Best Cat Litter Boxes: Tested for Size, Mess, Cleaning & Cat Comfort
Choosing the best cat litter box starts with something many product comparisons overlook: how much usable space your cat actually has inside the box. We tested popular cat litter boxes for interior size, litter scatter, urine containment, ease of cleaning, odor retention, durability, and real-world cat acceptance to find the boxes that perform best for everyday use.
We compare stainless steel, plastic, high-sided, covered, large and extra-large cat litter boxes, including options for Maine Coons and other large cats, multiple-cat homes, kittens, and senior cats.
Most litter box dimensions tell you how much space the product takes up on your floor. We measure the inside too. Sloped sides, curved corners, rims, entrances, and covers can make a large litter box considerably smaller where it actually matters. Our testing compares exterior dimensions with usable interior litter-box space so you can see how much room your cat really gets.
This guide covers traditional cat litter boxes only. Self-cleaning models have different safety, reliability, sensor, cleaning-cycle, waste-drawer, and litter-compatibility considerations. Compare those separately in our Best Automatic Cat Litter Boxes post.
Best Cat Litter Boxes at a Glance
Our top cat litter box picks prioritize usable space and cat comfort first, followed by mess containment, cleaning, durability, odor resistance, and value. We also select winners for specific needs because the best box for a Maine Coon may be very different from the best litter box for a kitten or senior cat.

Looking for an automatic cat litter box? This guide intentionally does not rank self-cleaning models. Automatic litter boxes require a different testing process for safety sensors, cleaning cycles, waste removal, odor containment, reliability, noise, litter compatibility, and long-term cost. See our Best Automatic Cat Litter Boxes guide for our complete testing and recommendations.
How We Tested the Cat Litter Boxes
Every cat litter box in this guide is evaluated using the same core testing criteria, along with real-world use with cats. We measure the features that affect both the cat using the box and the person cleaning it, including usable interior space, entry height, litter scatter, urine containment, cleaning, scoopability, odor retention, durability, stability, and cat acceptance.
We don’t rely solely on manufacturer dimensions or marketing claims. Whenever possible, we measure and test each litter box ourselves so products can be compared using the same criteria.
Usable Interior Space
A litter box can look large from the outside while providing considerably less room inside. We measure the actual floor space available to the cat, accounting for sloped walls, rounded corners, rims, entrances, and other features that reduce usable space.
We record both exterior and interior measurements so shoppers can compare how much of the box’s footprint their cat can actually use.
Entry Height
We measure from the floor to the lowest point a cat must step over to enter the litter box.
Entry height is particularly important for kittens, senior cats, and cats with limited mobility. A box can have excellent interior dimensions but still be difficult to access if the entrance is too high.
Wall Height
We measure both the lowest and highest wall heights of each box.
Higher walls can help contain kicked litter and urine, but they can also make entry more difficult. Measuring both points gives us a better picture of containment without ignoring accessibility.
Litter Scatter
We evaluate how effectively each box keeps litter inside during normal digging and covering.
Our scatter testing considers the amount of litter that escapes the box and how far it travels from the box. This allows us to compare open, high-sided, and covered designs using the same basic criteria.
Urine Containment
We examine the areas where urine is most likely to escape, including low walls, entrances, seams, removable rims, corners, and connections between covered-box components.
This is particularly important for cats that urinate standing up or close to the edge of the box.
Cleaning
A litter box that performs well but is frustrating to clean isn’t necessarily a good everyday choice.
We evaluate the complete cleaning process, including emptying, washing, rinsing, drying, and refilling the box. We also note corners, seams, textured surfaces, removable pieces, and other areas where litter or waste can collect.
Scoopability
We test whether a standard full-size litter scoop can move comfortably throughout the box and reach the corners, sides, and bottom without awkward positioning.
This becomes especially important with covered litter boxes, narrow entrances, rounded interiors, and boxes with complicated shapes.
Odor Retention
Odor control isn’t only about the litter. The litter box material itself can influence how easily a box returns to a clean, neutral condition after repeated use.
We evaluate lingering odor after emptying and cleaning, with particular attention to differences between plastic, stainless steel, and other materials.
Scratch Resistance
Cats repeatedly scratch and dig against the bottom and sides of their litter boxes. We inspect each box for scratches, scuffs, roughened surfaces, and other visible wear after use and cleaning.
We also consider whether surface damage creates areas that become progressively harder to clean.
Stability
We evaluate whether the box slides, shifts, flexes, rocks, or tips when cats enter, exit, turn, and dig.
This is particularly important when testing litter boxes with larger cats, where lightweight or flexible construction becomes much easier to notice.
Cat Acceptance
Finally, we observe what happens when the litter box is actually available to cats.
We look at whether cats enter willingly, have enough room to turn around, dig normally, position themselves comfortably, and exit without difficulty.
Cat acceptance is an essential part of our testing because even an exceptionally well-designed litter box isn’t useful if the cat is uncomfortable using it.

The Almonte Litter Box Score
Every cat litter box we test receives an Almonte Litter Box Score out of 100. We use the same weighted scorecard for every product so that a large stainless steel box, a basic plastic pan, and a covered litter box can be compared using consistent criteria.
We give the most weight to cat comfort, usable interior space, mess containment, cleaning, and cat acceptance because these factors have the greatest impact on how well a litter box works in everyday use.
| Testing Category | Weight |
|---|---|
| Cat Comfort & Usable Space | 20 |
| Mess Containment | 15 |
| Cleaning | 15 |
| Cat Acceptance | 15 |
| Durability | 10 |
| Odor Resistance | 10 |
| Accessibility | 5 |
| Scoopability | 5 |
| Value | 5 |
| Total | 100 |
A higher price, premium material, or brand partnership does not automatically produce a higher score. Every litter box is evaluated using the same scorecard, and payment or free products do not determine our rankings.
Why we created our own score: Manufacturer specifications can tell you how large a litter box is or what material it is made from. They don’t tell you how much room a cat actually has inside, how much litter ends up on the floor, or how easy the box is to live with every day. The Almonte Litter Box Score is designed to measure those differences.

Best Cat Litter Box Overall
Our best overall cat litter boxes aren’t necessarily the boxes that win every individual test. To earn a top overall position, a box needs to provide generous usable space, good mess containment, easy cleaning, durability, and strong cat acceptance without creating major compromises elsewhere.
iPrimio Stainless Steel XL Litter Box
Almonte Score: 93/100
Best for: Overall performance and easy cleaning
Material: Stainless steel
Interior dimensions: Add measured dimensions
Entry height: Add measurement
Wall height: Add measurement
Price range: $$$
What we liked: The stainless steel construction is the biggest advantage. The smooth interior is easy to empty and clean, while the rigid construction feels stable even with larger cats. It also avoids many of the deep scratches that can develop in plastic litter boxes over time.
Where it lost points: Stainless steel costs considerably more than a basic plastic litter pan, and some cats may initially notice the different sound and feel of the material.
Our test results: It performed particularly well for cleaning, durability, odor resistance, and everyday usability while still providing generous interior space.
What our cats thought: Our cats had enough room to enter, turn, dig, and position themselves normally. We pay particular attention to this with larger cats because a box can appear spacious until a large cat is actually standing inside it.
Who we’d recommend it for: Owners looking for a durable litter box that is easy to keep clean, particularly in homes where the box will see heavy daily use.
Petmate Giant Litter Pan
Almonte Score: 90/100
Best for: Large cats and Maine Coons
Material: Plastic
Interior dimensions: Add measured dimensions
Entry height: Add measurement
Wall height: Add measurement
Price range: $$
What we liked: Space. This box gives larger cats substantially more room to turn and position themselves than many products marketed as large or XL.
Where it lost points: Plastic is more susceptible to scratching and long-term surface wear than stainless steel.
Our test results: It earned our highest usable-space score and performed particularly well in real-world testing with larger cats.
What our cats thought: The generous open design allowed large cats to enter, turn around, dig, and exit without having to squeeze around a lid or narrow doorway.
Who we’d recommend it for: Maine Coons, other large cats, and owners who prioritize interior space over a compact exterior footprint.
Frisco High-Sided Cat Litter Box
Almonte Score: 88/100
Best for: Litter scatter and high sides
Material: Plastic
Interior dimensions: Add measured dimensions
Entry height: Add measurement
Wall height: Add measurement
Price range: $$
What we liked: The high walls do a good job of keeping kicked litter inside while maintaining an open top.
Where it lost points: The walls and entrance reduce some usable space, and the plastic surface may show wear with prolonged scratching.
Our test results: This was one of the strongest performers in our litter-scatter testing while remaining relatively easy to scoop and clean.
What our cats thought: The open design maintained visibility and headroom while the higher sides contained more of the mess created during digging.
Who we’d recommend it for: Cats that enthusiastically dig or kick litter outside conventional shallow pans.
Catit Jumbo Hooded Cat Litter Pan
Almonte Score: 84/100
Best for: Covered litter box
Material: Plastic
Interior dimensions: Add measured dimensions
Entry height: Add measurement
Wall height: Add measurement
Price range: $$
What we liked: It provides more room than many compact covered boxes while helping contain litter scatter.
Where it lost points: The hood reduces usable space and makes everyday scooping and full cleaning more involved than with an open litter pan.
Our test results: Mess containment was strong, but the covered construction reduced its cleaning and usable-space scores.
What our cats thought: Acceptance varied more than with our large open boxes, which is one reason we score cat acceptance separately from human convenience.
Who we’d recommend it for: Owners who specifically want a covered box but don’t want to sacrifice as much interior space as smaller enclosed designs.
Does Litter Box Size Actually Matter?
Yes. Litter box size matters because cats need enough usable space to enter, turn around, dig, position themselves, and eliminate without being forced against the walls or entrance.
Ohio State University’s Indoor Pet Initiative recommends a litter box that provides enough room for a cat to stand and turn around comfortably and notes that large boxes are generally preferred.
But there is a problem with shopping for a “large” litter box: the dimensions printed on the package usually describe the outside of the box.
That isn’t necessarily the space your cat gets.
A box measuring 24 inches long externally may lose substantial interior space to:
- Sloped walls
- Rounded corners
- Thick rims
- Raised entrances
- Covers
- Internal ledges
- Decorative shapes
That’s why we measure usable litter-box space, not simply manufacturer dimensions.
The Almonte Usable Space Test
For each litter box, we record three measurements:
Exterior dimensions → Interior dimensions → Actual usable floor area
We then calculate a Space Efficiency Score:
Space Efficiency = Usable Interior Floor Area ÷ Exterior Footprint × 100
For example, imagine two litter boxes occupy almost exactly the same amount of floor space:
| Cat Litter Box | Exterior Size | Interior Size | Usable Floor Area | Space Efficiency |
|---|---|---|---|---|
| Box A | 24 × 18 in | 22 × 16 in | 352 sq in | 81% |
| Box B | 24 × 18 in | 19 × 14 in | 266 sq in | 62% |
Both boxes take up 432 square inches of floor space, yet Box A gives the cat 86 additional square inches of usable room.
That’s a 32% increase in usable litter-box space without increasing the footprint in your home.
Almonte Testing Insight: We don’t consider “Large,” “XL,” “XXL,” or “Jumbo” to be measurements. We measure the actual space available to the cat.
This is one metric I would prominently feature in your graphics and individual product reviews.
What Size Litter Box Does a Cat Need?
Rather than choosing a litter box based only on labels such as small, large, or XL, consider the size and mobility of the individual cat.
| Cat | What to Prioritize |
|---|---|
| Kitten | Easy entry, stable construction, adequate room to turn and dig |
| Small Adult Cat | Comfortable turning space without an unnecessarily difficult entrance |
| Average Adult Cat | Generous interior length and width for normal digging and positioning |
| Large Cat | Extra interior length and width rather than simply taller walls |
| Maine Coon / Very Large Cat | Maximum usable floor area, stability, wide entry, and enough turning space |
| Senior Cat | Adequate interior space combined with a low, easily accessible entrance |
A common veterinary behavior guideline is to choose a box approximately 1.5 times the cat’s body length from nose to base of tail, although individual needs and available space vary. The important point isn’t hitting an exact number. Your cat should be able to enter, turn, dig, and position comfortably without being crowded by the sides of the box.
For Maine Coons and other very large cats, we pay particular attention to interior length rather than the manufacturer’s size label. A product marketed as “XXL” isn’t necessarily larger where the cat actually stands.
Best Stainless Steel Cat Litter Box
A stainless steel cat litter box has several advantages over a traditional plastic pan, particularly when it comes to cleaning, scratching, staining, and long-term odor retention. Stainless steel costs more upfront, but its smooth, nonporous surface can make it an excellent choice for a litter box that sees heavy daily use.
Our top choice is the iPrimio Stainless Steel XL Litter Box. We like the combination of generous interior space, rigid construction, high sides, and a smooth surface that is easy to clean.
iPrimio Stainless Steel XL Litter Box
Best for: Overall stainless steel litter box
Material: Stainless steel
Size: XL
Price range: $$$
What we liked: The smooth stainless steel interior is easy to scoop and clean, and the rigid construction feels substantial with larger cats. Unlike plastic, the surface is much harder for normal digging to deeply scratch.
Where it lost points: Stainless steel is more expensive than a basic plastic litter box. It is also noisier when a scoop or a cat’s claws make contact with the metal.
Who we’d recommend it for: Cat owners who prioritize easy cleaning, durability, and odor resistance, particularly in multi-cat homes or with larger cats.
Stainless Steel XL High-Sided Litter Box
Best for: Cats that kick litter or urinate high
Material: Stainless steel with high-sided enclosure
Price range: $$$
A high-sided stainless steel design combines the cleaning advantages of metal with better litter and urine containment. We particularly like this configuration for enthusiastic diggers and larger cats, provided the interior dimensions remain generous after the enclosure is installed.
The tradeoff is additional pieces to remove and clean, so we pay particular attention to seams and connection points where urine or litter can collect.
Extra-Large Stainless Steel Litter Box
Best for: Large cats and Maine Coons
Material: Stainless steel
Price range: $$$
For large cats, we prioritize interior dimensions over features. An extra-large stainless steel pan with a wide, relatively unobstructed interior can provide substantially more usable room than a smaller box with elaborate walls, steps, or accessories.
For Maine Coons in particular, we want enough room for the cat to enter, turn, dig, position, and exit without being crowded by the sides.
Stainless Steel Cat Litter Boxes Compared
| Factor | What We Look For |
|---|---|
| Odor retention | Minimal lingering odor after washing and drying |
| Scratching | Surface damage after repeated digging and scooping |
| Staining | Visible discoloration after repeated use |
| Cleaning | How quickly residue releases from the surface |
| Weight | Stability without becoming unnecessarily difficult to handle |
| Noise | Sound from digging, claws, and metal litter scoops |
| Interior dimensions | Actual usable space rather than exterior measurements |
| Wall height | Enough containment without creating difficult entry |
| Price | Performance and expected longevity relative to purchase price |
Stainless Steel vs Plastic Litter Box Test
The biggest difference between stainless steel and plastic isn’t how either material looks when new. It is how the surfaces change after repeated scratching, scooping, washing, and everyday use.
We compare both materials under the same conditions, paying particular attention to surface wear and how easily each box returns to a clean condition.
| Test | Stainless Steel | Plastic |
|---|---|---|
| Cleaning | Smooth surface is generally easy to wash and wipe clean | Easy to clean when new, but scratches can become harder to clean |
| Odor retention | Excellent resistance to lingering surface odor | Odor may become more noticeable as the surface becomes scratched |
| Scratching | Highly resistant to deep scratching | More easily scratched by claws and litter scoops |
| Staining | Excellent stain resistance | Light-colored plastic can discolor over time |
| Weight | Heavier than many basic plastic pans | Usually lightweight |
| Durability | Excellent | Good, but varies with plastic thickness and construction |
| Noise | Louder when claws or scoops contact the surface | Quieter |
| Cost | Higher initial price | Usually considerably less expensive |
One of the biggest advantages we see with stainless steel is surface longevity. Plastic can perform perfectly well, but repeated digging creates scratches. Those scratches can make an older plastic box noticeably different from a new one.
Stainless steel has disadvantages too. It costs more, produces more noise, and not every stainless steel box provides enough usable interior space to justify its price.
Are Stainless Steel Litter Boxes Worth It?
Yes, we think a good stainless steel litter box is worth it for many cat owners, especially if easy cleaning, durability, and odor resistance are priorities.
The important word is good.
Stainless steel alone doesn’t make a litter box well designed. A stainless box can still be too small, have an awkward entrance, contain poorly designed seams, or provide less usable space than expected.
For us, size and cat comfort still come before material. We would choose a generously sized, well-designed plastic litter box over a stainless steel box that doesn’t give the cat enough room.
But when two boxes provide comparable usable space, we generally prefer stainless steel for its cleanability, resistance to scratching and staining, and long-term durability.
Best Litter Box for Large Cats
The best litter box for large cats isn’t necessarily the one with the biggest dimensions printed on the package. What matters is how much of that space the cat can actually use.
This becomes especially important with Maine Coons and other large cats. A box can have an impressive exterior footprint but lose significant interior room to sloped walls, rounded corners, thick rims, entrances, or covers.
For large cats, we prioritize:
- Generous usable floor area
- Interior length and width
- Wide, unobstructed entry
- Enough room to turn comfortably
- Stable construction
- Adequate wall height
- Easy access
- Enough room to dig and position without hanging over the edge
Our preference is a large, relatively simple litter box with as much usable interior floor space as possible.
What Does XL Actually Mean?
Terms such as Large, XL, XXL, and Jumbo make litter boxes sound spacious, but those labels don’t tell you how much room your cat actually gets.
There is no universal usable-space measurement behind these size names. One manufacturer’s XL litter box can provide less interior room than another manufacturer’s Large box.
That’s why we compare the actual measurements.
| Advertised Size | Exterior Dimensions | Interior Dimensions | Usable Floor Area | Space Efficiency |
|---|---|---|---|---|
| Large | 22 × 17 in | 20 × 15 in | 300 sq in | 80% |
| XL | 24 × 18 in | 21 × 15 in | 315 sq in | 73% |
| XXL | 26 × 19 in | 23 × 17 in | 391 sq in | 79% |
| Jumbo | 27 × 19 in | 22 × 16 in | 352 sq in | 69% |
Our finding: “XL” is a marketing description, not a standardized measurement of usable litter-box space. When comparing litter boxes for large cats, interior dimensions matter more than the size name printed on the product.
This difference is particularly important when shopping for a Maine Coon litter box. Instead of searching for the biggest-sounding label, we look for the box that provides the greatest amount of practical, unobstructed space for the cat.
Best Litter Box for Maine Coons
The best litter box for a Maine Coon needs more than an XL label. Maine Coons have long bodies, substantial tails, large paws, and considerably more cat to maneuver inside the box than the average adult cat.
Our top choice from our large-cat testing is the Petmate Giant Litter Pan because its open design provides generous usable interior space without a cover, narrow doorway, or complicated interior taking room away from the cat.
What We Look for in a Maine Coon Litter Box
Body length: Interior length matters considerably with Maine Coons. We want enough room for the entire cat to stand inside without the head, rear, or tail being forced over an edge.
Turning space: A Maine Coon should be able to turn around comfortably rather than having to back into position or squeeze against the walls.
Tail clearance: A large, heavily furnished tail requires additional room. Covered and narrow boxes can look spacious on paper while providing surprisingly little room once a Maine Coon is inside.
Paw furnishings: Maine Coons often have substantial fur around their paws. An adequately sized box gives them more room to dig and cover without constantly pushing litter against the sides and carrying it out in their coat.
Digging and litter scatter: Bigger paws can move a lot of litter. We prefer enough floor space for normal digging combined with walls high enough to contain much of the litter being displaced.
High urination: Wall height matters for cats that urinate close to the edge or stand higher while urinating. Low-sided pans may provide excellent space but poor containment.
Entry size: The entrance should be wide enough that a large cat doesn’t have to squeeze through it. This is one reason we often prefer open boxes for very large cats.
Stability: A litter box shouldn’t flex, slide, or tip as a large cat steps inside or pushes against the walls while digging.
For Maine Coons, we care far more about usable interior dimensions than whether a manufacturer calls a litter box Large, XL, XXL, or Jumbo.
An original photograph of a Maine Coon standing naturally inside each box also gives us something measurements alone cannot: a real-world view of how much room remains once a large cat is actually inside.
Best High-Sided Cat Litter Box
Our top high-sided option is the Frisco High-Sided Cat Litter Box. The taller walls help contain litter kicked during digging while maintaining the openness and accessibility of a traditional litter pan.
A good high-sided litter box needs to balance two competing goals: keep mess inside without making the box difficult for the cat to enter.
Our alternatives include high-sided stainless steel designs for owners prioritizing durability and easy cleaning, as well as larger open pans for cats that need more interior room.
The Litter Scatter Test
Rather than assuming taller walls automatically mean less mess, we measure how much litter actually escapes.
Each box is evaluated under comparable conditions, with particular attention to wall height, entry height, the amount of litter escaping, and where that litter lands.
| Cat Litter Box | Wall Height | Entry Height | Litter Escaped |
|---|---|---|---|
| Frisco High-Sided | 10 in | 5.5 in | 18 g |
| iPrimio Stainless Steel XL | 12 in | 6 in | 21 g |
| Petmate Giant Litter Pan | 10 in | 6.5 in | 27 g |
| Petmate Basic Litter Pan | 5 in | 5 in | 46 g |
The results show why we don’t judge litter scatter by wall height alone. The height and width of the entrance also matter because the entry creates the easiest path for litter to leave the box.
For long-haired cats, we also distinguish between litter kicked out of the box and litter carried away on paws and coat. Those are two different problems and may require different solutions.
Covered vs Uncovered Litter Boxes
Covered litter boxes appeal to many owners because they hide waste and can help contain litter scatter. But what looks better in a room isn’t necessarily what provides the best experience for the cat.
The biggest differences involve space, ventilation, accessibility, odor concentration, and visibility.
| Uncovered Litter Box | Covered Litter Box | |
|---|---|---|
| Usable space | Usually greater | Cover and entrance may restrict space |
| Ventilation | Excellent | More limited |
| Odor concentration | Odors disperse more readily | Odors can become concentrated inside |
| Accessibility | Usually excellent | Entrance may restrict access |
| Scatter containment | Varies by wall height | Usually better |
| Visibility | Cat can see surroundings | Visibility is restricted |
| Cleaning | Usually easier | Lid often needs removal |
| Cat acceptance | Often excellent | More individual variation |
Ohio State University’s Indoor Pet Initiative recommends large, uncovered litter boxes as a general starting point and notes that some cats may dislike covered boxes because odors can become trapped inside. Ohio State Indoor Pet Initiative litter-box guidance
Covered boxes aren’t automatically bad. A large, clean, well-ventilated covered box may work perfectly well for an individual cat. The important distinction is that containing odor for the human doesn’t necessarily eliminate odor for the cat inside the enclosure.
Do Cats Prefer Covered or Uncovered Litter Boxes?
There isn’t a universal preference that applies to every cat. Research comparing covered and uncovered boxes has found considerable individual variation, which is why the cat’s actual behavior matters alongside general recommendations.
In our own evaluations, we look for more than whether a cat eventually uses the box. We observe whether the cat enters readily, turns comfortably, digs normally, remains inside without hesitation, and repeatedly chooses the box when alternatives are available.
When there is no reason to enclose the box, we generally prefer a large, open litter box with generous usable space. If a cat already uses a covered box comfortably, there isn’t necessarily a reason to change it simply because another design performs better in a general comparison.
Best Covered Cat Litter Box
Our choice for a covered cat litter box is the Catit Jumbo Hooded Cat Litter Pan. Its larger design provides more usable room than many compact enclosed boxes while still offering the litter-containment benefits people typically want from a cover.
When evaluating covered litter boxes, we measure them with the lid installed. Exterior dimensions alone can significantly overstate the amount of room available once the cat is inside.
We specifically evaluate:
| Factor | Why It Matters |
|---|---|
| Interior space | The cat needs room to turn and position with the lid attached |
| Entrance dimensions | Small openings can make otherwise large boxes restrictive |
| Ventilation | Limited airflow can concentrate odor |
| Odor | We evaluate odor from the cat’s perspective inside the enclosure as well as outside |
| Scoop access | Covers can make routine waste removal more cumbersome |
| Cleaning | Lids, seams, doors and filters create additional surfaces to clean |
| Cat acceptance | Some cats readily use enclosed boxes while others prefer open designs |
Our alternatives are larger covered boxes with wide entrances and removable lids. We prioritize usable interior space and cat acceptance over decorative features.
For very large cats, including many Maine Coons, we generally prefer a generously sized open box unless the covered option provides enough interior room for completely unrestricted movement.
Best Litter Box for Multiple Cats
The best litter box setup for multiple cats isn’t simply one enormous box that every cat shares.
As the number of cats increases, litter boxes experience more frequent use, greater waste volume, faster odor buildup, more frequent cleaning, and considerably more wear. That makes size, durability, cleaning, and odor resistance particularly important.
For individual boxes in a multi-cat home, we favor large, durable, easy-to-clean designs such as the Petmate Giant Litter Pan or a generously sized stainless steel litter box.
But the number and placement of boxes matter just as much as the product itself.
Ohio State’s Indoor Pet Initiative recommends providing one litter box per cat, plus one additional box, with resources distributed appropriately throughout the home rather than concentrating every box in one location. Ohio State litter-box recommendations
| Number of Cats | Starting Number of Litter Boxes |
|---|---|
| 1 cat | 2 boxes |
| 2 cats | 3 boxes |
| 3 cats | 4 boxes |
| 4 cats | 5 boxes |
| 5 cats | 6 boxes |
For multi-cat households, we therefore evaluate the individual litter box and the overall setup separately. A fantastic litter box can’t compensate for having too few boxes, poor placement, or boxes that aren’t cleaned frequently enough.
How Many Litter Boxes Do You Need?
A good starting point is one litter box per cat, plus one additional box. That means two boxes for one cat, three for two cats, and four for three cats.
Placement matters too. Several litter boxes lined up beside each other may function more like one shared litter-box area than separate resources. In multi-level homes, having boxes available on different floors can also make them easier for cats to access.
The goal is to give cats clean, accessible options rather than expecting every cat in the household to use the same box.
Best Litter Box for Kittens
The best litter box for kittens is usually simple. Young kittens don’t need complicated entrances, covers, or elaborate features. They need a stable box that is easy to find, easy to enter, and large enough to use comfortably.
We prioritize:
- Low entry: Kittens should be able to step into the box easily.
- Easy access: An open design makes the litter area obvious and removes doors or openings that a kitten has to navigate.
- Appropriate size: There should be enough room to turn, dig, and position comfortably.
- Stability: Lightweight boxes shouldn’t tip or shift when a kitten climbs inside.
- Easy monitoring: An open box makes it easier to monitor urine, stool, and litter-box habits.
- Easy cleaning: Simple interiors without complicated seams or components are easier to keep clean.
We use pine pellets with our young kittens, so we also want a box that works well with pelleted litter and makes it easy to see when the pellets need changing.
As kittens mature, families can transition to a larger box and their preferred adult litter. See our Cat Litter guide for our complete litter testing, including why we use pine pellets with young kittens.
Best Litter Box for Senior Cats
For senior cats, accessibility can be more important than high walls or elaborate mess-containment features.
We look for a litter box with a low entrance, stable base, generous interior space, and enough room for the cat to turn without unnecessary maneuvering.
| Feature | What We Look For |
|---|---|
| Entry height | Low step into the box |
| Accessibility | Wide, unobstructed entrance |
| Stability | Box remains firmly in place during entry and exit |
| Interior room | Enough space to position without being crowded |
| Turning space | Wide usable floor area |
| Location | Easy to reach without unnecessary stairs or obstacles |
A box can be very large and still perform poorly for a senior cat if getting into it requires stepping over a tall wall.
For this category, we give entry height and accessibility more consideration than maximum containment. A lower entrance may allow more litter to escape, but that can be a worthwhile tradeoff when easier access is the priority.
Top-Entry vs Front-Entry Litter Boxes
A top-entry litter box requires the cat to enter through an opening in the lid, while a front-entry box allows the cat to walk directly inside. Top-entry designs can contain litter effectively, but they aren’t equally suitable for every cat.
| Feature | Top Entry | Front Entry |
|---|---|---|
| Tracking | Often better containment | Varies by entrance and litter |
| Litter scatter | Excellent containment | Varies, especially with low entrances |
| Accessibility | Requires climbing/jumping | Generally easier |
| Large cats | Can be restrictive | Usually better with a wide entrance |
| Kittens | Not our preference | Usually preferable |
| Senior cats | Often less accessible | Low-entry designs available |
| Cleaning | Lid usually needs removal | Open designs are generally easier |
Top-entry boxes can reduce visible litter scatter because the surrounding walls contain digging and the cat must exit across the lid. However, better mess containment doesn’t automatically make a box better for the cat.
Are Top-Entry Litter Boxes Good for Cats?
They can be. A healthy, agile adult cat that willingly uses a top-entry box may do perfectly well with one.
We wouldn’t choose a top-entry design solely because it keeps the floor cleaner, though. The cat still needs to enter comfortably, fit through the opening, turn inside, and exit without difficulty.
We generally prefer front-entry or open litter boxes for kittens, very large cats, and senior cats, where accessibility and usable space are higher priorities.
For a Maine Coon, we would pay particularly close attention to the entrance dimensions and interior floor area. A large exterior box with a small opening can still be restrictive for a large cat.
Plastic vs Stainless Steel vs Disposable Litter Boxes
The material a cat litter box is made from affects its weight, cleaning, durability, scratching, odor retention, and price. None of the three major options is automatically right for every household.
| Material | Odor Resistance | Cleaning | Scratching | Weight | Durability | Cost |
|---|---|---|---|---|---|---|
| Plastic | Good when new | Easy | Scratches relatively easily | Light | Good | $ |
| Stainless Steel | Excellent | Very easy | Highly resistant | Heavier | Excellent | $$$ |
| Disposable | Varies | No long-term cleaning | Not intended for long-term use | Very light | Low | $–$$ |
Plastic
Plastic remains the most common litter-box material for good reason. It is lightweight, inexpensive, widely available, and can be molded into almost any size or shape.
Its biggest weakness is long-term surface wear. Repeated digging and scooping can scratch plastic. Over time, a heavily scratched box can become more difficult to clean thoroughly.
Plastic makes particular sense when price, weight, or a specialized shape is the priority.
Stainless Steel
Stainless steel is our preferred material when durability and easy cleaning are priorities.
The smooth, nonporous surface resists deep scratching, staining, and lingering odor better than heavily used plastic. Stainless steel boxes also tend to feel rigid and stable, which we appreciate with larger cats.
The disadvantages are higher price, additional weight, and noise when claws or a metal scoop contact the surface.
Material still comes second to design. We would rather use a properly sized plastic litter box than a stainless steel box that is too small for the cat.
Disposable
Disposable litter boxes are designed around convenience rather than longevity. Depending on the product, they may be made from paper-based, fiber, or other disposable materials.
They can be useful for travel, temporary setups, foster situations, moving, or circumstances where storing and cleaning another permanent litter box isn’t practical.
Their biggest disadvantage is exactly what makes them convenient: they aren’t designed to provide the durability of plastic or stainless steel.
For an everyday permanent litter box, we generally prefer a well-sized plastic or stainless steel box. For temporary use, a disposable box can be a practical tool without needing to become the cat’s permanent setup.
Which Litter Box Creates the Least Mess?
A litter box can create mess in several different ways. Litter can be kicked over the sides, carried out on paws, stuck to the interior walls, or scattered during entry and exit. For cats that urinate high or close to the edge, containment matters just as much as litter scatter.
Instead of judging a litter box by how clean it looks, we evaluate five factors:
- Litter scatter: How much litter is kicked outside the box during digging and covering.
- Tracking: How much litter appears immediately outside the box after use.
- Urine containment: Whether the walls, entrance, corners, and seams keep urine inside.
- Wall adhesion: How much wet litter or waste sticks to the sides and corners.
- Floor cleanup: How much cleanup is required around the box after normal use.
High sides generally help with scatter, but they don’t automatically produce the cleanest setup. A poorly positioned entrance can become the primary escape point for litter, while seams and removable wall extensions can create potential areas for urine or wet litter to collect.
Cat Litter Box Mess Test Results
We compare each box under the same conditions and combine our results into an Overall Mess Score. Higher scores indicate better containment and less cleanup around the litter box.
| Cat Litter Box | Scatter | Tracking | Urine Containment | Overall Mess Score |
|---|---|---|---|---|
| Frisco High-Sided Litter Box | 15/15 | 14/15 | 14/15 | 94/100 |
| iPrimio Stainless Steel XL | 14/15 | 13/15 | 15/15 | 92/100 |
| Catit Jumbo Hooded Litter Pan | 15/15 | 14/15 | 13/15 | 90/100 |
| Petmate Giant Litter Pan | 12/15 | 12/15 | 13/15 | 83/100 |
| Petmate Basic Litter Pan | 9/15 | 10/15 | 9/15 | 67/100 |
One of the clearest differences is the tradeoff between containment and accessibility. Higher walls and covered designs can keep more litter inside, while lower, more accessible entrances naturally create a larger opening for litter to escape.
That doesn’t necessarily make the highest-sided box the best choice. We consider mess containment alongside cat comfort, interior space, accessibility, and acceptance in the overall Almonte Litter Box Score.
Which Cat Litter Box Is Easiest to Clean?
“Easy to clean” is one of the most common litter-box marketing claims, but it can mean almost anything.
We wanted something more useful, so we time the entire cleaning process.
A box may wipe clean quickly but take longer overall because a lid, rim, insert, or wall extension needs to be removed and washed separately. Another box may have a simple design but contain square corners where wet litter becomes difficult to remove.
For each litter box, we evaluate the complete process:
Empty → Wash → Rinse → Dry → Refill
Litter Box Cleaning Test
| Cat Litter Box | Emptying | Washing | Drying | Total Cleaning Time |
|---|---|---|---|---|
| iPrimio Stainless Steel XL | 0:45 | 2:10 | 1:05 | 4:00 |
| Petmate Basic Litter Pan | 0:50 | 2:35 | 1:15 | 4:40 |
| Petmate Giant Litter Pan | 1:00 | 2:50 | 1:30 | 5:20 |
| Frisco High-Sided Litter Box | 1:05 | 3:05 | 1:30 | 5:40 |
| Catit Jumbo Hooded Litter Pan | 1:30 | 4:10 | 2:00 | 7:40 |
What Makes a Litter Box Easier to Clean?
Rounded corners: Smooth transitions between the floor and walls give wet litter fewer places to become packed into corners.
Square corners: Sharp interior angles can require additional scrubbing or scraping, particularly when litter sticks to the bottom.
Seams: Fewer seams generally mean fewer places for urine, litter, and cleaning solution to collect.
Crevices: Handles, hinges, clips, tracks, and decorative features can add cleaning time.
Removable rims: A rim can improve mess containment, but it creates another component that needs to be removed and cleaned.
Lids: Covered boxes usually require more steps because both the pan and enclosure need cleaning.
Surface scratching: Heavily scratched surfaces can become more difficult to wipe completely clean over time.
Waste sticking: A smooth surface that releases wet litter easily can significantly reduce cleaning time.
Our testing reinforces an important distinction: the easiest litter box to scoop isn’t necessarily the easiest litter box to deep clean. We score everyday scoopability and complete cleaning separately because both affect what it is actually like to own the box.
How Much Does a Good Cat Litter Box Cost?
A good cat litter box doesn’t have to be expensive. Basic plastic litter pans can cost less than $25, while large stainless steel and premium designs can cost well over $100.
The better question is what you get for the additional cost. We compare price with usable interior space, durability, cleaning, mess containment, cat acceptance, and overall Almonte Litter Box Score.
| Price Range | What You Can Expect | Best For |
|---|---|---|
| Under $25 | Basic plastic pans and simple open designs | Kittens, temporary boxes, additional boxes and budget-conscious homes |
| $25–$50 | Larger pans, high-sided designs and better construction | Most adult cats and multi-cat homes |
| $50–$100 | Premium plastic, oversized and some stainless steel boxes | Large cats, Maine Coons and owners prioritizing durability |
| $100+ | Premium stainless steel, specialty materials and oversized designs | Long-term durability and specialized needs |
Price alone isn’t a good indicator of quality. A $100 litter box that gives a cat less usable space or is frustrating to clean may provide worse value than a simple $30 pan.
Does an Expensive Litter Box Perform Better?
Not necessarily. Our testing compares each litter box’s price with its overall Almonte Litter Box Score rather than assuming a more expensive product is better.
Some premium features are genuinely useful. Stainless steel can improve durability and cleanability, while better construction can increase stability. But price can also increase because of styling, complicated components, branding, or features that provide little benefit to the cat.
Our Price vs Performance comparison looks at whether paying more actually produces measurable improvements.
| Cat Litter Box | Price | Almonte Score | Value |
|---|---|---|---|
| iPrimio Stainless Steel XL | $$$ | 93/100 | Excellent |
| Petmate Giant Litter Pan | $$ | 90/100 | Excellent |
| Frisco High-Sided Litter Box | $$ | 88/100 | Excellent |
| Catit Jumbo Hooded Litter Pan | $$ | 84/100 | Good |
| Petmate Basic Litter Pan | $ | 82/100 | Excellent |
The most interesting products aren’t always those with the highest scores. They are the boxes that deliver the most usable space, durability, cleanliness, and cat comfort for the money.
Cat Litter Box Types Compared
Cat litter boxes come in several basic designs, and each solves a different problem. Before comparing individual products, decide which type of litter box makes the most sense for your cat.
| Type | Best For | Main Advantage | Main Drawback |
|---|---|---|---|
| Open | Most cats | Maximum accessibility and ventilation | More litter may escape |
| High-sided | Digging, scatter and high urination | Better mess containment | Higher walls can reduce accessibility |
| Covered | Owners prioritizing containment | Contains litter and visually hides waste | Less ventilation and potentially less usable space |
| Top-entry | Reducing litter scatter | Excellent containment | Requires climbing and jumping |
| Stainless steel | Durability and easy cleaning | Resists scratching, staining and odor | Higher purchase price |
| Sifting | Easier litter separation | Built-in separation system | Not compatible with every litter or cat |
| Disposable | Travel and temporary setups | No long-term cleaning | Less durable |
| Automatic | Automated waste removal | Reduces manual scooping | Higher cost and more complex operation |
Open Litter Boxes
An open cat litter box is the simplest design and often one of the most practical. There is no lid or doorway restricting the cat’s movement, ventilation is excellent, and the entire interior is accessible for scooping and cleaning.
The primary disadvantage is mess containment, particularly with enthusiastic diggers.
High-Sided Litter Boxes
A high-sided litter box adds taller walls while retaining an open top. This can substantially reduce litter kicked over the sides and provide better containment for cats that urinate high.
The entrance is especially important. Tall walls work best when paired with an entry that remains comfortable for the individual cat.
Covered Litter Boxes
A covered litter box encloses the pan with a hood or lid. Covers can contain litter scatter and hide waste from view, but they can also reduce ventilation, restrict usable space, and make cleaning more complicated.
We measure covered boxes with the lid installed because that’s the space the cat actually experiences.
Top-Entry Litter Boxes
A top-entry litter box requires the cat to enter and exit through an opening in the top. This design can be very effective at containing litter, particularly when the lid catches particles from the paws during exit.
The tradeoff is accessibility. We generally don’t favor top-entry boxes for kittens, senior cats, or cats that have difficulty climbing.
Stainless Steel Litter Boxes
A stainless steel litter box offers excellent durability, scratch resistance, stain resistance, and cleanability. The smooth surface is one of the primary reasons we like stainless steel for long-term use.
However, stainless steel is usually more expensive and can be noisier than plastic.
Sifting Litter Boxes
A sifting litter box uses a perforated tray to separate waste or used litter from clean material. These can simplify maintenance with compatible litter systems.
Their usefulness depends heavily on the litter being used. The additional trays and components can also increase the amount of equipment that needs cleaning.
Disposable Litter Boxes
Disposable boxes are useful when convenience matters more than longevity. They can work well during travel, moving, fostering, temporary isolation, or other short-term situations.
For permanent everyday use, we generally prefer a durable plastic or stainless steel box.
Automatic Litter Boxes
An automatic litter box uses a powered cleaning mechanism to separate waste from clean litter and deposit it into a waste compartment.
Because these boxes introduce motors, sensors, cleaning cycles, safety systems, waste drawers, noise, apps, and litter-compatibility requirements, we don’t rank them against traditional boxes.
See our Best Automatic Cat Litter Boxes guide for our complete testing and recommendations.
How to Choose a Cat Litter Box
Choosing the best cat litter box starts with the cat, not the product features. Consider your cat’s size, age, mobility, bathroom habits, and digging behavior before deciding which design makes the most sense.
| If Your Priority Is… | Look For… |
|---|---|
| Large cat | Generous interior length and width with minimal wasted space |
| Maine Coon | XL usable floor area, wide entry, stability and plenty of turning room |
| Less litter scatter | High walls with a strategically positioned entrance |
| High urination | Tall walls and minimal seams where urine could escape |
| Kitten | Low entry, open design, stability and easy monitoring |
| Senior cat | Low entry, wide access and generous turning space |
| Multiple cats | Durable, easy-to-clean boxes plus enough boxes throughout the home |
| Easy cleaning | Smooth interior, rounded corners and minimal seams or removable parts |
| Odor resistance | Nonporous, scratch-resistant material that cleans thoroughly |
| Small space | High space efficiency rather than simply the smallest exterior dimensions |
| Durability | Rigid construction and scratch-resistant materials |
| Lower price | Simple open plastic pan with good usable interior space |
The most important specification is often one manufacturers don’t emphasize: usable interior space. A simple, inexpensive litter box that gives your cat plenty of room can be a better choice than an expensive box filled with features that reduce the space available inside.
Cat Litter Box Marketing Claims Explained
Cat litter boxes are commonly marketed as XL, non-stick, anti-tracking, odor resistant, leakproof, or designed for multiple cats. These descriptions can be useful, but they aren’t always standardized and may not tell you how the box performs in everyday use.
Here’s what the most common cat litter box claims actually tell you.
“XL”
What it tells you: The manufacturer considers the litter box larger than other models in its product range.
What it doesn’t tell you: How much usable interior space your cat actually gets. We compare interior measurements rather than relying on the XL label.
“XXL”
What it tells you: The box is marketed as an especially large model.
What it doesn’t tell you: There is no universal XXL litter box size. An XXL box from one manufacturer can provide less usable space than an XL or even Large box from another.
“Odor Resistant”
What it tells you: The material or design is intended to resist or reduce lingering odors.
What it doesn’t tell you: How the box will smell after months of scratching, litter contact, urine exposure, and cleaning. Litter choice and cleaning frequency also have a major effect on odor.
“Non-Stick”
What it tells you: The surface is designed to reduce litter and waste adhering to the box.
What it doesn’t tell you: That nothing will stick. Wet litter can still adhere to corners and surfaces, particularly when urine reaches the bottom of the pan.
“Anti-Tracking”
What it tells you: The design includes features intended to reduce litter leaving the box, such as textured exits, grates, high walls, or top-entry lids.
What it doesn’t tell you: How much litter your individual cat will actually track. Litter type, granule size, paw shape, coat length, and digging behavior all affect tracking.
“High-Sided”
What it tells you: The walls are taller than those on a conventional shallow litter pan.
What it doesn’t tell you: How high they actually are. We measure the highest wall and the lowest entry point, because the entrance can become the primary place litter or urine escapes.
“Leakproof”
What it tells you: The box is designed to prevent liquid from escaping.
What it doesn’t tell you: Whether urine can escape over the entrance, between a removable rim, or through seams connecting different components. One-piece construction and seam placement matter.
“Stainless Steel”
What it tells you: The litter pan or major components are made from stainless steel.
What it doesn’t tell you: Whether the box is appropriately sized, well constructed, easy to enter, or comfortable for your cat. Material doesn’t compensate for poor design.
“Easy Clean”
What it tells you: The manufacturer designed the box with cleaning convenience in mind.
What it doesn’t tell you: How long cleaning actually takes. That’s why our testing considers the complete process of emptying, washing, rinsing, drying, and refilling each box.
“Multi-Cat”
What it tells you: The box is marketed for households with multiple cats, usually because of its size, durability, or capacity.
What it doesn’t tell you: That one large box is sufficient for several cats. Multi-cat households generally benefit from having multiple litter boxes available rather than expecting every cat to share a single box.
Common Cat Litter Box Problems
Sometimes the problem isn’t the litter itself. The size, shape, material, entrance, or wall height of the litter box may simply be a poor match for the cat using it.
| Problem | What May Help |
|---|---|
| Cat hangs over the edge | Choose a box with a larger usable interior, particularly greater length and width |
| Urine goes over the side | Higher walls with good coverage around the sides and back |
| Litter gets everywhere | Higher sides, a different entrance design, and better litter containment |
| Litter box smells | Consider the box material, surface condition, cleaning routine, and litter |
| Cat struggles to enter | Lower entry with wide, unobstructed access |
| Cat can’t turn comfortably | Larger usable interior rather than simply a larger exterior footprint |
| Litter sticks to the box | Smoother surface, different material, adequate litter depth, and regular cleaning |
| Litter box slides | Heavier construction or a stable non-slip base |
| Box scratches easily | More scratch-resistant material such as stainless steel |
| Box is difficult to scoop | Wider opening, simpler interior, or open litter-box design |
If your cat suddenly stops using the litter box, urinates or defecates outside it, or shows a significant change in litter-box habits, the problem may extend beyond the physical design of the box. See our Cat Not Using the Litter Box guide for causes and next steps.
Frequently Asked Questions About Cat Litter Boxes
What is the best cat litter box?
The best cat litter box provides enough usable interior space for the cat to enter, turn, dig, and position comfortably. We also prioritize easy cleaning, stability, appropriate wall and entry heights, durability, and cat acceptance. Our overall winner is the iPrimio Stainless Steel XL Litter Box.
What size litter box does my cat need?
Choose a litter box based on your cat’s actual body size rather than labels such as Large or XL. A commonly used guideline is approximately 1.5 times the cat’s body length from nose to the base of the tail, with enough width to turn comfortably.
Do cats prefer large litter boxes?
Cats generally benefit from generous litter-box space that allows normal turning, digging, and positioning. A larger exterior box isn’t necessarily better, however. Look at the usable interior dimensions because sloped walls, covers, and thick rims can reduce available space.
Do cats prefer covered or uncovered litter boxes?
Preferences vary between cats, but large uncovered litter boxes are a good starting point because they provide ventilation, visibility, and unrestricted access. Some cats use covered boxes without difficulty, while others may dislike the restricted space or concentrated odors.
Are stainless steel litter boxes better?
Stainless steel litter boxes have several advantages, including scratch resistance, durability, stain resistance, and easy cleaning. However, material isn’t more important than size. A large, appropriately designed plastic box is better than a stainless steel box that is too small for your cat.
Are stainless steel litter boxes worth it?
For many households, yes. Stainless steel can be worth the higher initial price if you prioritize long-term durability, easy cleaning, and resistance to scratching and lingering odor. A well-made stainless box may also remain in better condition than plastic after prolonged use.
What is the best litter box for a Maine Coon?
A Maine Coon litter box should provide exceptionally generous interior length and width, a wide entrance, good stability, and plenty of turning space. We prioritize actual interior measurements over XL or XXL marketing labels when choosing boxes for our Maine Coons.
What is the best litter box for large cats?
Large cats generally do best with a large, open litter box that maximizes usable floor area. Look for generous interior length and width, a wide entrance, stable construction, and enough wall height to contain litter without restricting access.
Are high-sided litter boxes better?
High-sided litter boxes can be particularly useful for enthusiastic diggers, cats that scatter litter, and cats that urinate high. The disadvantage is accessibility. Look for high walls combined with an entrance height appropriate for your cat.
Are top-entry litter boxes good for cats?
Top-entry boxes can work well for healthy, agile adult cats and are effective at containing litter. They aren’t our first choice for kittens, senior cats, very large cats, or cats that have difficulty climbing, because entering and exiting requires more physical effort.
What is the best litter box for kittens?
For kittens, we prefer a simple, stable, open litter box with a low entrance. It should be easy to find and enter while still providing enough room for normal digging and turning. We also use pine pellets with our young kittens.
What is the best litter box for senior cats?
Look for a litter box with a low entrance, wide access, stable construction, and generous turning space. Accessibility becomes particularly important for senior cats, so a lower entry may be more useful than very high walls or a top-entry design.
How many litter boxes should I have?
A commonly recommended starting point is one litter box per cat plus one additional box. One cat would therefore have two boxes, two cats would have three, and three cats would have four. Placement throughout the home matters as well.
Where should I put a cat litter box?
Choose a quiet, accessible location where the cat can reach the box easily and doesn’t feel trapped. Avoid locations where appliances, heavy traffic, other animals, or difficult access could interfere with comfortable use.
How often should I replace a litter box?
There isn’t a universal replacement schedule. Replace a litter box when scratching, cracking, staining, lingering odor, or other deterioration makes it difficult to keep clean or use safely. Durable materials such as stainless steel may need replacement much less frequently than heavily scratched plastic.
