Best Cat Litter: Tested for Odor, Dust, Tracking & Clumping

The best cat litter should control odor, clump well, produce minimal dust, and stay in the litter box instead of spreading throughout your home. We tested popular cat litters for odor control, dust, tracking, clumping, absorption, waste, and real-world performance with cats. Using our 100-point Almonte Cat Litter Score, we compare each litter using the same criteria to find which products actually perform best, including our top choices for kittens, long-haired cats, multiple cats, and automatic litter boxes.

Best Cat Litter at a Glance

There isn’t one cat litter that performs best in every category. Some excel at odor control but track more, while others produce less dust but don’t clump as firmly. These are our current top picks.

How We Tested the Cat Litters

Cat litter claims can be difficult to compare because terms like “low dust,” “low tracking,” and “strong odor control” don’t always mean the same thing from one brand to another. To make our comparisons more useful, we evaluate each cat litter using the same core criteria, combining controlled tests with observations from normal litter box use.

Dust

We perform a controlled pour test using the same amount of litter and pouring conditions. We look at the visible dust produced while pouring, dust that settles around the litter box, and dust generated during scooping.

Tracking

We evaluate how much litter leaves the box during normal use, including particles immediately surrounding the box and those carried farther into the room.

Odor Control

We compare how effectively each litter controls urine and fecal odor over time. Both initial odor control and how well the litter performs between routine scooping are considered.

Clumping Speed

For clumping litters, we measure how quickly the litter forms a stable clump after contact with liquid. Faster isn’t necessarily better if the resulting clump remains soft or breaks apart.

Clump Strength

Once a clump has formed, we evaluate how well it holds together during normal scooping. Strong clumps generally leave less contaminated litter behind and make the box easier to maintain.

Absorbency

We use a consistent volume of liquid to compare how much litter is required to contain and absorb it. This helps identify differences that aren’t obvious from bag size or weight alone.

Scoopability

We evaluate how easily waste can be removed without excessive crumbling, sticking to the litter box, or taking clean litter along with it.

Litter Waste

We look at how much clean litter is unintentionally removed during routine scooping. A litter that is inexpensive per pound may not be a good value if a large amount is discarded with every clump.

Coat Carryout

Tracking can be particularly noticeable with long-haired cats. We look at how readily litter becomes caught between the toes, in paw furnishings, and in longer coat before being carried away from the litter box.

Cat Acceptance

Performance doesn’t matter if cats don’t want to use the litter. Alongside controlled testing, we observe whether cats readily use each litter and note hesitation or avoidance when it occurs.

Value

Rather than judging value by the price of the bag alone, we consider price, performance, litter consumption, and waste together. This gives a better picture of what a cat litter actually costs to use over time.

The Almonte Cat Litter Score

To make cat litter comparisons consistent, we created the Almonte Cat Litter Score, a 100-point rating system based on the factors that have the greatest impact on everyday litter box use.

Every cat litter is evaluated using the same scorecard. Odor control receives the greatest weight, followed by dust, tracking, and clumping. We also account for absorption, waste, scoopability, cat acceptance, and value.

The final score is intended to show overall performance, not simply which litter performs best in one area. A litter with exceptional odor control, for example, may still lose points if it produces significant dust, tracks heavily, or wastes a large amount of clean litter during scooping.

Individual category scores are also shown throughout this guide so you can prioritize the characteristics that matter most in your home.

The table below brings our testing results together in one place. Overall scores are calculated using the Almonte Cat Litter Score above, while individual scores make it easier to compare products based on specific priorities such as odor, dust, tracking, or clumping.

About Our Ratings: Our cat litter scores are updated as we test and retest products. Because formulas, packaging, and product performance can change over time, the results shown here reflect the products available at the time of our evaluation. Every litter is evaluated using the same Almonte Cat Litter Score criteria to keep comparisons as consistent as possible.

Pelleted Cat Litter for Kittens

We use pelleted litter for young kittens rather than traditional fine-grained clumping litter. Young kittens explore their environment with their mouths and may occasionally chew or ingest litter while learning to use the litter box. Larger pellets help reduce access to loose, fine litter during this stage.

Pelleted litter is also typically low tracking and easy to monitor, which makes it practical for kitten areas and early litter training.

Pelleted Cat Litter Options for Kittens

Our Choice for Young Kittens

We typically use pine pellets with our kittens. They are inexpensive, absorbent, low dust, and the larger pellet size works well while kittens are learning appropriate litter box habits.

As kittens mature and are reliably using the litter box without attempting to eat the litter, they can gradually transition to the litter their family plans to use long term.

A note on bedding pellets: If using wood pellets that are not specifically marketed as cat litter, check the product ingredients before use. Choose plain, untreated pellets without added fragrances, chemicals, accelerants, or other additives.

Best Cat Litter Overall

The best cat litter needs to perform well across several categories rather than dominating just one. We gave the most weight to odor control, dust, tracking, and clumping, while also considering absorbency, scoopability, waste, cat acceptance, and overall value.

These are our strongest all-around performers.

Dr. Elsey’s Ultra Unscented

Almonte Score: 91/100

Best for: Overall everyday use
Litter type: Unscented clumping clay
Price range: $

What we liked: Dr. Elsey’s Ultra delivers a strong balance of clumping, odor control, and value. The clumps are firm enough for clean removal, and the unscented formula makes it a good option for households that prefer to avoid added fragrance.

Where it lost points: Tracking and dust were noticeable compared with some of the higher-performing products in those individual categories.

Our test results: It didn’t win every individual test, but it consistently scored well across the categories we consider most important. That consistency is why it earned our top overall position.

Who we’d recommend it for: Cat owners looking for a dependable clumping litter without paying a premium price.

BoxiePro Deep Clean Probiotic

Almonte Score: 90/100

Best for: Low dust and strong overall performance
Litter type: Unscented clumping clay
Price range: $$$

What we liked: BoxiePro performed particularly well for dust, clumping, and odor control. It produces firm clumps that are easy to scoop without leaving excessive residue behind.

Where it lost points: Price is its biggest disadvantage. It costs considerably more than many conventional clay litters.

Our test results: BoxiePro was one of the most consistent performers across our testing and came particularly close to taking the overall top position.

Who we’d recommend it for: Homes where reducing dust is a priority and paying more for litter isn’t a major concern.

Sustainably Yours Multi-Cat Plus

Almonte Score: 88/100

Best for: Strong clumping in a plant-based litter
Litter type: Corn and cassava
Price range: $$$

What we liked: The clumping performance stood out. It forms very firm clumps despite being a plant-based litter, making waste easy to remove cleanly.

Where it lost points: The fine texture can contribute to tracking, and its higher price lowered its value score.

Our test results: Sustainably Yours received one of our strongest clumping scores and performed competitively against traditional clay litters.

Who we’d recommend it for: Cat owners looking for a plant-based alternative without giving up strong clumping performance.

World’s Best Cat Litter Multiple Cat

Almonte Score: 87/100

Best for: Multi-cat households and lightweight litter
Litter type: Corn
Price range: $$

What we liked: World’s Best is noticeably lighter than traditional clay litter and combines clumping with good odor control. The lighter bags are also easier to carry and pour.

Where it lost points: Its clumps weren’t quite as firm as our highest-rated clumping litters, and tracking can still occur.

Our test results: It performed consistently across categories without a major weakness, particularly for households looking to move away from heavy clay litter.

Who we’d recommend it for: Multi-cat households that want a lightweight, plant-based clumping litter.

Arm & Hammer Clump & Seal Multi-Cat

Almonte Score: 86/100

Best for: Odor control
Litter type: Clumping clay
Price range: $$

What we liked: Odor control is where this litter stood out most clearly. It performed particularly well when the litter box experienced heavier use.

Where it lost points: Dust, tracking, and fragrance may make it less appealing to households prioritizing those characteristics.

Our test results: Its overall score was pulled upward by excellent odor performance, although several other litters provided a better balance across all categories.

Who we’d recommend it for: Multi-cat households where controlling litter-box odor is the highest priority.

Best Cat Litter for Odor Control

Our top choice for odor control is Arm & Hammer Clump & Seal Multi-Cat. It performed particularly well at controlling odor between scooping and remained effective under heavier litter-box use.

Runners-up: Dr. Elsey’s Ultra Unscented and BoxiePro Deep Clean Probiotic both provided strong odor control while performing better in some other categories.

Cat Litter Odor Test Results

The biggest difference wasn’t whether a litter could control fresh odor. Most of the better-performing products could. The separation became more noticeable between scooping and as the litter accumulated normal use. Strong clumping also mattered because litter that allowed contaminated material to break apart was more difficult to keep consistently fresh.

Best Low-Dust Cat Litter

BoxiePro Deep Clean Probiotic was our top low-dust performer. It produced less visible airborne dust during pouring and routine scooping than most of the clay litters we compared.

Dr. Elsey’s Ultra Unscented and Sustainably Yours Multi-Cat Plus were also strong alternatives for owners concerned about litter dust.

Cat Litter Dust Test Results

What Does “99% Dust Free” Actually Mean?

“99% dust free” sounds straightforward, but it doesn’t necessarily mean you will see no dust when pouring or scooping the litter.

Dust claims can also be difficult to compare between brands when consumers aren’t given the testing method used to produce the percentage. Particle size, shipping, handling, and material settling within the bag can all affect what you experience when you open it.

For that reason, we don’t award a dust score based on packaging claims. We evaluate the litter itself under the same pouring and scooping conditions used for the other products in our comparison.

Best Non-Tracking Cat Litter

Dr. Elsey’s Clean Tracks was our top choice for reducing tracking. Its larger, heavier granules were less likely to travel away from the litter box than many finer litters.

Fresh Step Clean Paws was a close alternative, particularly for households that want a clay litter specifically designed around reducing tracking.

Cat Litter Tracking Test Results

Does Cat Litter Granule Size Affect Tracking?

Granule size was one of the differences we noticed when comparing tracking. Larger, heavier particles generally stayed closer to the litter box in our testing, while very fine and lightweight particles were easier to carry away on paws.

Granule size isn’t the only factor, however. Particle weight, shape, litter depth, the cat’s coat and paws, and even how enthusiastically a cat exits the box can influence tracking.

This is particularly important with long-haired cats. Litter doesn’t only travel between the toes. Fine particles can become caught in paw furnishings and longer coat, which is why we evaluate coat carryout separately from ordinary floor tracking.

Best Clumping Cat Litter

Sustainably Yours Multi-Cat Plus produced the strongest overall clumping performance in our comparison, earning 15/15 for clumping.

Boxiecat Premium Unscented was another standout, while Dr. Elsey’s Ultra and BoxiePro both produced consistently strong clumps.

We evaluate more than whether litter simply “clumps.” Our testing considers how quickly the clump forms, how firmly it holds together, how much it crumbles during scooping, whether it sticks to the bottom of the box, and how much clean litter is removed along with it.

Cat Litter Clumping Test Results

Strong clumping matters for more than convenience. When a clump stays intact, less contaminated litter is left behind and less clean litter needs to be removed during scooping. That can affect odor control, litter consumption, and the actual cost of using the product over time.

Which Cat Litter Is Most Absorbent?

Absorbency affects more than how quickly litter handles urine. A highly absorbent litter may require less material to contain the same amount of liquid, which can reduce waste, keep the bottom of the box cleaner, and potentially lower the amount of litter used over time.

We test absorbency separately from clumping because a litter can form a strong clump without necessarily being the most efficient at absorbing liquid.

Cat Litter Absorption Test

For our absorption test, each litter is exposed to the same standardized volume of liquid. We then measure how much litter is required to fully contain the liquid without leaving excess moisture underneath.

Lower litter usage indicates greater absorption efficiency.

The differences can look small in a single test, but they become more meaningful when litter is used every day. A product that requires less litter to contain each urination may ultimately last longer, particularly in a multi-cat household.

About these results: Measurements are updated as products are tested and retested. Formula changes, moisture, storage, and normal variation between bags can affect litter performance.

Which Cat Litter Creates the Least Waste?

Bag price alone doesn’t tell you how economical a cat litter will be. Every time you scoop the box, some clean litter may be removed along with the waste.

Weak or oversized clumps can take a surprising amount of unused litter with them. Over weeks and months, that increases both litter consumption and cost.

This is why we include litter efficiency as part of our testing.

Cat Litter Efficiency Test

We measure the amount of clean litter unintentionally removed during standardized scooping. We also consider crumbling and residue left behind, since broken clumps can make it necessary to remove additional litter to get the box clean.

The most efficient litters generally formed compact, firm clumps that separated cleanly from the surrounding dry litter. Larger or more fragile clumps tended to remove more clean litter or leave pieces behind.

This also changes how we think about value. A more expensive bag may be economical if very little litter is wasted, while an inexpensive litter can become surprisingly costly if large amounts disappear every time the box is scooped.

Best Cat Litter for Long-Haired Cats

Long-haired cats create a litter problem that isn’t always captured by traditional tracking tests.

Litter can become trapped between the toes, caught in paw furnishings, or carried away in the longer hair around the legs, belly, and tail. Fine particles can travel surprisingly far before eventually falling from the coat.

Because we live and work with long-haired breeds, this is something we pay particular attention to when evaluating cat litter.

For long-haired cats, we consider:

• Granule size: Very fine particles can become caught more easily between toes and in long fur.
• Particle weight: Extremely lightweight litter may travel farther from the box.
• Paw furnishings: Hair growing between and around the paw pads can collect litter that would otherwise remain in the box.
• Coat adhesion: Some litter sticks to damp paws or longer coat more readily than others.
• Dust: Fine dust can settle on paws and coat even when larger particles remain inside the box.
• Tracking: We consider both litter immediately surrounding the box and particles carried farther into the home.

Our current choice for long-haired cats is Dr. Elsey’s Clean Tracks, primarily because its larger, heavier granules performed well in our tracking comparisons.

The Coat Carryout Test

Our Coat Carryout Test goes a step beyond measuring litter found on the floor.

We look at how much litter remains caught between the toes, around the paw furnishings, and in the surrounding coat immediately after a cat leaves the litter box. We then compare this with the amount of litter eventually deposited outside the immediate litter-box area.

What We’ve Learned From Long-Haired Cats

Our experience with Maine Coons, Ragdolls, and British Longhairs has made us much more conscious of the difference between ordinary tracking and coat carryout.

Maine Coons can have substantial paw furnishings that trap small particles between the toes. Ragdolls also have heavily furnished paws and longer body coats that can carry litter beyond the immediate litter-box area. British Longhairs have dense coats and furnished paws that create many of the same considerations.

For these cats, the litter with the absolute lowest tracking score isn’t necessarily the litter with the strongest odor or clumping performance. We look for a balance between granule size, particle weight, dust, clumping, and how readily the litter releases from the coat.

That is why we score long-haired cat performance separately rather than simply applying our overall cat litter ranking to every breed.

Best Cat Litter for Multiple Cats

Our favorite cat litter for multiple cats is World’s Best Cat Litter Multiple Cat. It is also the litter we prefer for our own adult cats because it offers a good balance of odor control, clumping, low dust, weight, and everyday ease of use.

Multi-cat households put much greater demands on litter than single-cat homes. More cats mean more urine, larger overall clump volume, faster litter consumption, more frequent scooping, and potentially more odor. A litter that performs well with one cat may become expensive or difficult to maintain when several cats share litter boxes.

World’s Best Multiple Cat is made from whole-kernel corn and forms scoopable clumps without the weight of traditional clay litter. We particularly like that it is lightweight, easy to pour, and performs well with frequent scooping.

Why World’s Best Is Our Pick

• Good odor control in multi-cat environments
• Lightweight compared with clay
• Reliable clumping
• Relatively low dust
• Easy to scoop
• Less cumbersome when filling multiple litter boxes
• Plant-based formula
• Works well for our long-haired adult cats

Alternatives: BoxiePro Deep Clean Probiotic is a strong choice if clumping and low dust are the priority. Dr. Elsey’s Ultra Unscented offers very good overall performance at a lower price, while Arm & Hammer Clump & Seal Multi-Cat is worth considering when odor control is the primary concern.

For households with several cats, we would also consider cost per month rather than price per bag. How quickly the litter is consumed, how much clean litter gets removed during scooping, and how frequently boxes need topping off can make a substantial difference in the true cost.

Best Cat Litter for Kittens

Our litter recommendation changes when we’re dealing with young kittens. We prefer pelleted litter for kittens, particularly during the early weeks when they are still learning appropriate litter box habits and may investigate litter with their mouths.

Rather than prioritizing maximum clumping performance, we look for a litter that is low dust, unscented, easy to monitor, and made from simple materials.

What We Look for in Kitten Litter

Texture: Larger pellets are our preference for young kittens rather than very fine litter.

Dust: We favor low-dust products because kittens spend a surprising amount of time digging, playing, and investigating their litter boxes.

Scent: Unscented litter is our preference. Strong fragrance isn’t necessary for maintaining a clean kitten box.

Acceptance: The best kitten litter is ultimately one the kitten will consistently use. Changes should be made gradually rather than abruptly replacing a familiar litter.

Introducing new litter: When a kitten goes home, we recommend initially continuing with the type of litter the kitten already knows. A new litter can then be introduced gradually by mixing increasing amounts with the familiar litter.

Our Preferred Kitten Litters

We typically use pine pellets with young kittens. Cat-specific options include Feline Pine Original and ExquisiCat Naturals Pine, while recycled paper pellets such as Fresh News and So Phresh provide another non-clumping pellet option.

As kittens mature and are no longer attempting to chew or eat litter, families can gradually transition to their preferred adult cat litter.

What We Avoid With Very Young Kittens

We don’t use fine clumping litter with very young kittens that may still attempt to eat their litter. Clumping litter is designed to absorb moisture and form a mass, so ingestion is something we prefer to avoid during this exploratory stage.

Once kittens are older and reliably using their litter box, there are many more litter options available.

Best Cat Litter for Automatic Litter Boxes

Automatic litter boxes place different demands on litter. A product that works perfectly in a traditional litter box may not work well with a machine that relies on sifting, rotating, raking, or separating clumps automatically.

Our current overall pick is World’s Best Cat Litter although the best choice ultimately depends on the specific automatic litter box and the manufacturer’s litter requirements.

What Matters in an Automatic Litter Box

Granule size: Litter needs to pass through the machine’s sifting system correctly. Litter that is too large or unusually shaped may not separate properly.

Clump strength: Weak clumps can break during a cleaning cycle, leaving contaminated particles behind.

Clumping speed: Automatic boxes may begin cleaning relatively soon after a cat leaves. The litter needs enough time to form a stable clump before the cleaning cycle begins.

Dust: Mechanical movement can stir up litter repeatedly, making low-dust performance particularly valuable.

Waste: Some automatic boxes remove more clean litter than others. A compact clump can help reduce the amount of unused litter deposited in the waste drawer.

Compatibility: This is the most important consideration. Always check the litter requirements for your particular automatic litter box before changing products.

Our Top Picks for Automatic Litter Boxes

Our favorite is World’s Best Cat Litter Multiple Cat, which is also our preferred litter for our adult cats. We like its combination of reliable clumping, low weight, odor control, and easy everyday cleanup. When compatible with the automatic litter box, it is our first choice.

For automatic litter boxes, compatibility still matters. Check the manufacturer’s litter requirements before choosing a product, since some automatic boxes require specific litter materials, textures, or granule sizes.

Best Natural Cat Litter

Natural cat litter has expanded far beyond traditional pine pellets. Today, cat owners can choose from pine, corn, tofu, wheat, grass, and recycled paper, with substantial differences in clumping, tracking, weight, odor control, and cost.

Our favorite natural cat litter for adult cats is World’s Best Cat Litter Multiple Cat. The corn-based formula provides the convenience of clumping litter while remaining lightweight and easy to scoop. We also like its odor control and find it practical for multi-cat households.

For young kittens, however, we prefer non-clumping pine pellets.

Our winner: World’s Best Cat Litter Multiple Cat for adult cats. For kittens or cats that need a simpler litter setup, pine pellets remain one of our favorite alternatives.

Cat Litter Types Compared

The material used to make cat litter has a major influence on how it feels, clumps, tracks, absorbs moisture, and controls odor. There isn’t one material that is automatically superior in every category.

Clay Cat Litter

Clay is the most familiar cat litter material. Clumping varieties generally use bentonite clay, which absorbs moisture and forms scoopable clumps.

Pros: Strong clumping, good odor control, widely available, and relatively inexpensive.
Cons: Heavy, can be dusty, and smaller particles may track.
Best suited for: Owners who prioritize strong clumping, easy scooping, and affordability.

Crystal Cat Litter

Crystal litter is made primarily from silica gel granules that absorb moisture rather than forming traditional clay-style clumps.

Pros: Lightweight, highly absorbent, good odor control, and generally low dust.
Cons: More expensive, texture may not appeal to every cat, and many varieties don’t clump.
Best suited for: Owners prioritizing moisture and odor control with less frequent full litter replacement.

Pine Cat Litter

Pine litter is commonly made from compressed wood pellets that break down as they absorb moisture.

Pros: Very low dust, inexpensive, larger particles track less, and simple to monitor.
Cons: Most pellet varieties don’t clump, and sawdust needs to be removed as pellets break down.
Best suited for: Kittens, cats that tolerate pellets well, and owners looking for an economical non-clumping option.

Tofu Cat Litter

Tofu litter is generally produced from soybean or other plant fibers compressed into small pellets.

Pros: Lightweight, absorbent, low dust, and usually clumping.
Cons: More expensive than conventional clay and not as widely available.
Best suited for: Owners wanting a lightweight plant-based clumping litter.

Corn Cat Litter

Corn litter uses processed corn to create a lightweight, absorbent litter capable of forming scoopable clumps.

Pros: Lightweight, clumping, plant-based, and easier to carry than clay.
Cons: Fine particles can track, and it generally costs more than basic clay litter.
Best suited for: Owners wanting plant-based litter without giving up clumping. This is the category we currently prefer for our adult cats.

Wheat Cat Litter

Wheat-based litter uses processed wheat and starches to absorb moisture and form clumps.

Pros: Lightweight, biodegradable, and naturally clumping.
Cons: Clump strength and odor control vary between products.
Best suited for: Owners looking for another plant-based alternative to clay.

Grass Cat Litter

Grass litter is typically produced from grass seed or grass fibers and has a fine, lightweight texture.

Pros: Strong clumping, highly absorbent, lightweight, and generally low dust.
Cons: Fine particles can track easily and the price is often higher.
Best suited for: Owners who prioritize strong clumping in a lightweight plant-based litter.

Paper Cat Litter

Paper litter is made from recycled paper compressed into pellets or soft granules.

Pros: Very low dust, lightweight, soft, and easy to monitor.
Cons: Most varieties don’t clump and odor control can be more limited.
Best suited for: Young kittens and situations where a simple, low-dust litter is desirable.

Clumping vs Non-Clumping Cat Litter

The biggest difference is what happens after the litter absorbs urine. Clumping litter forms a removable mass, while non-clumping litter absorbs moisture without creating a scoopable clump.

For most adult cats, we prefer clumping litter because it makes daily waste removal easier. For young kittens, we take the opposite approach and use non-clumping pellets.

Scented vs Unscented Cat Litter

Scented litter is primarily designed to make the litter box smell better to people. Cats experience scent very differently, and a heavily fragranced litter isn’t necessarily more appealing to the cat using the box.

Research into feline litter-box preferences has found that cats can show preferences related to litter substrate and odor, although individual cats vary. For that reason, we generally favor unscented litter and control odor through good litter performance and frequent scooping rather than fragrance.

Unscented doesn’t mean odor control is unimportant. A good unscented litter can control odor through absorption, clumping, and removal of contaminated litter without adding perfume to the box.

Clay vs Natural Cat Litter

Neither clay nor natural litter automatically wins. There are excellent and poor-performing products in both categories.

Clay remains difficult to beat for strong clumping, widespread availability, and price. Natural litter becomes particularly appealing when weight, material, or dust are priorities.

Our own preference demonstrates why the distinction isn’t particularly useful on its own. We use corn-based World’s Best with our adult cats and pine pellets with young kittens. We choose based on how the litter performs for the situation rather than whether the package says “natural.”

What Type of Cat Litter Do Cats Prefer?

Cats don’t read litter reviews. The features that make litter convenient for us aren’t necessarily the features that determine whether a cat wants to stand, dig, and eliminate in it.

What Humans Want

Most owners understandably prioritize:

• Low dust
• Minimal tracking
• Strong odor control
• Easy scooping
• Low cost
• Less litter around the house

What Cats May Prefer

Cats may respond more strongly to:

• Texture: How the litter feels underneath their paws
• Scent: Many cats may prefer little or no added fragrance
• Comfort: The substrate needs to be comfortable for standing and digging
• Cleanliness: A dirty box can make even a preferred litter less appealing
• Familiarity: Abruptly replacing a familiar substrate can sometimes cause resistance

This is also why the highest-scoring litter isn’t automatically the right litter for every cat.

What We Do When a Cat Doesn’t Like Its Litter

When we have a cat that is struggling with a litter or suddenly becomes reluctant to use it, we often go back to simple pine pellets.

Pellets provide a familiar, straightforward substrate that we already use extensively with our kittens. Once the cat is consistently comfortable with the litter box again, we can decide whether there is any reason to transition to another litter.

If a cat suddenly stops using the litter box altogether, however, we don’t assume the litter is responsible. Sudden changes in litter-box habits can also have behavioral or medical causes and warrant further investigation.

The takeaway is simple: the best cat litter is one that performs well for you and that your cat is comfortable using consistently.

How Much Does Cat Litter Really Cost?

The cheapest bag of cat litter is not necessarily the least expensive litter to use. Bag size, litter density, clump size, clean litter lost during scooping, and how often the box needs to be topped up all affect the real cost.

For that reason, we look at price per pound, estimated monthly use, and performance together rather than ranking litter by package price alone.

The prices below are examples based on retail prices checked in August 2026 and will change by retailer, package size, and promotions. For example, Dr. Elsey’s Ultra was listed around $20.69 for 40 pounds, World’s Best around $39.99 for 28 pounds, BoxiePro around $33.99 for 28 pounds, and Sustainably Yours around $39.99 for 20 pounds.

Important: The 20-pound comparison above standardizes price by weight. It does not mean every litter will require 20 pounds per month. Lightweight and highly absorbent litters can behave very differently from dense clay litter, which is why we also track actual litter consumption during testing.

Cheapest Cat Litter vs Best Value

There is an important difference between cheap cat litter and good-value cat litter.

Dr. Elsey’s Ultra has one of the lowest costs per pound in our comparison and also performs strongly overall, which makes it particularly competitive on value.

World’s Best costs considerably more per pound, but weight alone doesn’t tell the whole story. World’s Best notes that its 28-pound bag can last more than 67 days for two cats under its stated usage assumptions. In our own evaluation, we also consider litter consumption and how much clean litter is thrown away during scooping.

That’s why our Value Score considers:

• Purchase price
• Amount of litter used
• Clean litter wasted while scooping
• Clump efficiency
• Overall performance

A litter can therefore cost more at checkout and still represent good value if it lasts longer or wastes less product.

Does Expensive Cat Litter Perform Better?

Not necessarily.

Our preliminary price-to-performance comparison shows that a higher price per pound does not automatically produce a higher overall score. Dr. Elsey’s Ultra, for example, costs substantially less per pound than several premium litters in our comparison while remaining one of our strongest overall performers. Current retail prices also illustrate how wide the difference can be, from roughly $0.52 per pound for Dr. Elsey’s Ultra to about $2.00 per pound for Sustainably Yours in the package sizes checked.

For our final testing, we compare price per pound against the Almonte Cat Litter Score.

What our data shows: Paying more for cat litter does not guarantee better overall performance. The better question is how much performance you get for what you actually spend.

Cat Litter Cost Calculator

Bag prices make it surprisingly difficult to compare cat litter. A 40-pound bag costing $25 may look more expensive than a $20 bag until you account for the package size and how quickly each litter is actually used.

Our Cat Litter Cost Calculator lets you estimate what your current litter costs over a month and an entire year.

The calculator is particularly useful when comparing a traditional clay litter with a lightweight or plant-based litter because bag price alone doesn’t show how much the litter will actually cost you over time.

How to Choose Cat Litter

The right cat litter depends on both what matters most in your home and what your cat is comfortable using. Odor control may be the priority in a multi-cat household, while owners of long-haired cats may care more about tracking and litter caught in the coat.

Use this table as a quick starting point:

For our own adult cats, we prefer World’s Best Cat Litter Multiple Cat as an all-around litter. For young kittens, we prefer pine pellets.

The most important consideration is still your cat. A litter can perform exceptionally well in testing, but it isn’t the right choice if your cat doesn’t want to use it.

Cat Litter Marketing Claims Explained

Cat litter packaging is full of terms such as “99% dust free,” “low tracking,” and “odor control.” These claims can be useful, but they don’t always make it easy to compare one product with another.

Here’s what some of the most common cat litter claims actually tell you, and what they don’t.

“99% Dust Free”

A “99% dust free” claim does not necessarily mean you will see no dust when pouring or scooping the litter.

The result can depend on how the manufacturer measures dust, as well as shipping, handling, particle breakdown, and settling inside the package. Unless two products were evaluated using the same testing method, their percentages aren’t necessarily directly comparable.

This is why we evaluate visible dust ourselves rather than assigning scores based on package claims.

“Low Tracking”

Low-tracking litter is designed to reduce the amount of litter carried away from the box, often through changes in particle size, shape, or weight.

It doesn’t mean no tracking. Your cat’s paws, coat length, litter depth, litter mat, and even how the cat exits the box can affect how far litter travels.

For long-haired cats, we also look at coat carryout, because litter caught in paw furnishings and coat may travel farther than litter carried directly on the paws.

“Multi-Cat”

“Multi-cat” generally indicates that the product is marketed for households with more than one cat, often with an emphasis on odor control or clumping.

It doesn’t automatically mean it will outperform every standard litter in a multi-cat home.

We look at odor, clump strength, absorption, waste, consumption, and cost together when evaluating litter for multiple cats.

“Odor Control”

Odor-control claims can refer to several different mechanisms, including absorption, fragrance, activated carbon, baking soda, or other odor-control ingredients.

A scented litter isn’t necessarily better at controlling odor. Strong clumping can also make a significant difference because contaminated litter can be removed more completely.

We prefer to evaluate how the litter actually performs between scooping rather than how strongly the fresh litter smells.

“Lightweight”

Lightweight litter weighs less for a comparable volume, making bags easier to carry, pour, and store.

The tradeoff is that lighter particles may sometimes travel more easily outside the litter box. Lightweight also doesn’t necessarily mean economical. Compare how much litter you actually use, rather than package weight alone.

“Natural”

There is no single type of natural cat litter.

Products marketed as natural may contain corn, pine, wheat, grass, tofu, paper, or other plant-derived materials. These materials behave very differently from one another.

“Natural” tells you something about the source material. It does not automatically tell you how well the litter controls odor, clumps, tracks, produces dust, or whether your cat will like it.

“Biodegradable”

Biodegradable generally means the litter material can be broken down by biological processes under appropriate conditions.

That doesn’t necessarily mean used cat litter belongs in your backyard compost, can be disposed of outdoors, or will rapidly break down in a landfill. Disposal recommendations depend on the litter material, local waste rules, and the fact that used litter contains animal waste.

“Flushable”

Some plant-based cat litters are marketed as flushable, but that doesn’t mean flushing is appropriate for every home or municipality.

Plumbing systems, septic systems, local wastewater rules, and the disposal of cat waste all need to be considered. A flushable label should not be treated as universal permission to put cat litter down the toilet.

Common Cat Litter Problems

Many frustrating litter problems can be improved simply by choosing a product with different physical characteristics. Before replacing the litter, however, consider whether the problem comes from the litter itself, the litter box setup, or a change in your cat’s behavior.

If the issue is how often the litter needs replacing, see our How Often to Change Cat Litter guide. For problems related to cleaning the box itself, see How to Clean a Litter Box.

If your cat suddenly begins avoiding the litter box or eliminating elsewhere, don’t assume the litter is the only cause. Changes in litter-box habits can have behavioral or medical causes and should be addressed separately.

Frequently Asked Questions About Cat Litter

What is the best cat litter?

The best cat litter balances odor control, clumping, dust, tracking, waste, and cost while still being comfortable for your cat to use. Our preferred litter for adult cats is World’s Best Cat Litter Multiple Cat because we like its combination of clumping, odor control, lightweight material, and everyday usability.

What type of cat litter do cats prefer?

Many cats prefer fine-textured, unscented litter, although individual preferences vary. Familiarity and cleanliness also matter. Ohio State and Cornell both note preferences for unscented, finer-textured substrates. When one of our cats struggles with a litter, we often return to simple pine pellets and reassess from there.

What cat litter controls odor best?

In our comparison, Arm & Hammer Clump & Seal Multi-Cat earned our highest odor-control score. Strong odor performance depends on more than fragrance. Absorption, clump strength, and how completely contaminated litter can be removed all contribute to keeping a litter box smelling clean.

What cat litter tracks the least?

Larger, heavier litter particles generally performed better in our tracking tests than very fine, lightweight litter. Dr. Elsey’s Clean Tracks was our highest-rated traditional litter for tracking. With long-haired cats, we also consider litter caught in paw furnishings and coat rather than measuring floor tracking alone.

What is the best low-dust cat litter?

BoxiePro Deep Clean Probiotic was our highest-rated low-dust clumping litter. We base our dust ratings on controlled pouring and use rather than relying exclusively on claims such as “99% dust free” printed on the package.

What is the best clumping cat litter?

Sustainably Yours Multi-Cat Plus and Boxiecat Premium Unscented produced some of the strongest clumps in our comparison. We evaluate clumping speed, strength, crumbling, adhesion to the box, and how much clean litter is accidentally removed during scooping.

What cat litter is best for multiple cats?

Our choice is World’s Best Cat Litter Multiple Cat. We prefer it for our own adult cats because it combines good odor control and clumping with a lightweight formula that is easier to manage when maintaining multiple litter boxes.

What cat litter is best for long-haired cats?

Look for litter that produces little dust and doesn’t readily become trapped between the toes or in paw furnishings. Our testing considers coat carryout in addition to ordinary tracking, which is particularly relevant for long-haired breeds such as Maine Coons, Ragdolls, and British Longhairs.

What litter is best for kittens?

We prefer non-clumping pine pellets for young kittens. The larger pellet format is low dust and avoids giving very young kittens access to fine clumping litter while they are still exploring their environment with their mouths. Once kittens mature, families can gradually transition to their preferred adult litter.

Is clay cat litter safe?

Clay litter is widely used for adult cats, but product choice and individual circumstances matter. We prefer non-clumping pellets for very young kittens that may investigate or chew litter. If your cat repeatedly eats litter rather than simply investigating it, discuss the behavior with your veterinarian.

Is natural cat litter better?

Not necessarily. “Natural” describes the material more than its performance. Corn, pine, tofu, wheat, grass, and paper litters behave very differently. We recommend comparing clumping, odor, dust, tracking, waste, cost, and cat acceptance rather than choosing a litter solely because it is marketed as natural.

Is scented or unscented cat litter better?

We generally prefer unscented litter. Both Cornell and Ohio State note that many cats prefer unscented litter, and some cats may be deterred by scented or deodorizing products. Good litter-box odor control should primarily come from effective litter and regular cleaning rather than heavy fragrance.

Is expensive cat litter worth it?

Sometimes, but price doesn’t reliably predict performance. A more expensive litter may be worthwhile if it clumps efficiently, lasts longer, or produces less waste. Our testing therefore compares price against actual performance and consumption, rather than assuming premium-priced litter is automatically better.

Can you mix two types of cat litter?

Yes, and mixing can be useful when transitioning a cat to a new litter. Cats can resist abrupt substrate changes, so gradually introducing the new litter can make the transition easier. Cornell recommends adding small amounts of a new litter to the familiar litter when changing brands.

How much cat litter should I use?

The ideal depth varies somewhat by litter and cat. Ohio State suggests around two inches as a general starting point, with enough substrate for the cat to scratch and bury waste comfortably. See our How Much Cat Litter to Use guide for a complete breakdown.

How often should I change cat litter?

Scoop waste at least daily and replace litter often enough to keep the box clean, dry, and acceptable to your cat. How frequently a complete change is necessary depends on the litter type, number of cats, and box setup. See our How Often to Change Cat Litter guide for specific schedules.

Our Cat Litter Testing & Review Policy

Our goal is to make our cat litter reviews useful whether a product was purchased by us, provided by a manufacturer, or included in a paid partnership.

Products we purchase: Many products included in our testing are purchased independently at retail.

Products provided by brands: We may accept cat litter and other products from manufacturers for evaluation. Receiving a free product does not guarantee positive coverage or a particular score.

Sponsored products: Some content may be created in partnership with a brand. Sponsored relationships are disclosed, and payment does not determine a product’s Almonte Cat Litter Score.

Affiliate relationships: We may earn a commission when readers purchase through certain links. Affiliate relationships do not change how products are tested, scored, or ranked.

Standardized testing: Products are evaluated using the same core testing criteria whenever applicable, including odor control, dust, tracking, clumping, absorption, waste, scoopability, cat acceptance, and value.

Scoring: Products receive an Almonte Cat Litter Score out of 100 using the weighted scoring system explained earlier in this guide.

Editorial independence: Manufacturers do not receive the ability to purchase a higher score or ranking. Unless specifically stated otherwise, brands do not approve our testing conclusions before publication.

Updates: We periodically retest products and update results as formulas change, new products become available, or additional testing gives us better information.

Our policy is simple: sponsorship, free products, and affiliate relationships do not determine testing scores or rankings.

Veterinary & Feline Behavior Sources

Our product-performance findings come from our own testing and real-world use. Veterinary and feline behavior sources are used separately to support statements about cat preferences, litter-box behavior, health, and safety.

Useful references for this guide include:

• Cornell Feline Health Center: Guidance on litter preferences, litter-box avoidance, changing litter gradually, and medical causes of inappropriate elimination.
  Cornell Feline Health Center
• Ohio State University Indoor Pet Initiative: Evidence-based information about litter substrate, cleanliness, box setup, and feline litter preferences.
  Ohio State Indoor Pet Initiative

This distinction is important. A veterinary source can tell us what is known about feline behavior or health, but it cannot tell us whether a particular bag of litter tracks less or forms stronger clumps. Those product claims come from our testing.
