Can British Shorthair Cats Be Calico
Yes. British Shorthair cats can be calico. Calico is not a color but a color pattern that includes black, red, and white. The pattern forms in large, clear patches. Calico British Shorthairs are recognized by CFA, TICA and GCCF. They are uncommon because the genetics that create calico are tied to the X chromosome and involve both black and red expression. Most calico British Shorthairs are female, and males are extremely rare.
People Also Ask About Calico British Shorthair Cats
What is a calico British Shorthair?
A calico British Shorthair is a purebred British Shorthair with three colors on its coat: black, red and white. The patches must be large and clearly separated for the cat to be considered a true calico. This pattern is fully recognized in major registries such as CFA, TICA and GCCF.
Are calico British Shorthair cats rare?
Yes. Calico British Shorthairs are rare because the pattern requires the correct combination of black, red and white genes that often appear only in select breeding lines. Most calicos are female, which makes male calico British Shorthairs even more uncommon.
Can British Shorthair cats be calico?
Yes. British Shorthairs can be calico and the pattern is accepted in all major registries. It is a naturally occurring tricolor pattern and does not affect the breed’s purity, temperament or structure.
Why are calico cats almost always female?
Calico coloring is tied to the X chromosome. Female cats have two X chromosomes, which allows both black and red pigment genes to appear. Male cats, which have only one X chromosome, rarely express both colors unless they carry an extra X chromosome.
Can male British Shorthairs be calico?
Male calico British Shorthairs are extremely rare and occur only when a genetic anomaly causes the kitten to inherit two X chromosomes and one Y chromosome. These males almost always prove sterile and are not used for breeding.
Do calico British Shorthair kittens change color?
Calico kittens keep the same general patch layout but the colors deepen as they grow. Black darkens, red becomes brighter and white becomes clearer. Full patch contrast typically appears between six and twelve months.
What is the difference between a tortoiseshell and a calico British Shorthair?
A tortoiseshell British Shorthair has black and red mixed or marbled together with little or no white. A calico has the same colors but arranged in large, distinct patches of black, red and white. Patch clarity is the key difference.
Are calico British Shorthair cats good pets?
Yes. Calico British Shorthairs have the same calm, loyal and easygoing temperament as all British Shorthairs. The color pattern does not influence personality. They are known for being steady, affectionate and well suited to families.
How much does a calico British Shorthair kitten cost?
Calico British Shorthair kittens usually cost more than common colors due to their rarity. Prices vary by breeder quality, pedigree, registration and region. Many calico kittens have waitlists because they do not appear in every litter.
Do calico British Shorthairs shed more?
No. Calico British Shorthairs shed the same amount as all British Shorthair colors. Their dense double coat sheds lightly throughout the year and more heavily during seasonal changes. Weekly brushing helps maintain their patches and keep white areas bright.
Can two non calico British Shorthairs produce a calico kitten?
Yes. If both parents carry the necessary genes for black, red and white spotting, they can produce calico kittens even if neither parent is visibly calico. The pattern can stay hidden for generations.
Are calico British Shorthairs show quality?
Calico British Shorthairs can be shown in the bicolor or tricolor category depending on registry rules. Pattern clarity, patch balance and coat density matter for show quality, along with proper British Shorthair structure and temperament.
Are calico cats more expensive than other British Shorthair colors?
Often yes. The limited supply and high demand for calicos usually places them in the higher price range. However, pedigree quality, breeder practices and health testing influence price more than color alone.
Do calico British Shorthairs have special health needs?
No. Calico coloring is not linked to health conditions in females. Rare male calicos may have genetic sterility, but this does not apply to female calicos. Regular British Shorthair care, a balanced diet and routine vet visits are sufficient.
Can British Shorthair cats be longhaired calicos?
Yes. British Longhair calicos can occur when both parents carry the longhair gene. These cats have the same calico pattern but with a longer, fuller coat and a plush outline. They are very rare and highly sought after.
What Makes a British Shorthair Purebred Regardless of Color
A purebred British Shorthair has documented lineage from registered British Shorthair parents and follows the breed standard for structure, coat and temperament. Purity is based on pedigree, registration, bone type, head shape and temperament. Purebred status is never determined by the color or pattern. This means a calico cat is not any less purebred than a solid blue, lilac or golden British Shorthair. Registration through TICA, CFA or GCCF verifies purity.
Calico British Shorthair Appearance
Coat Color
Calico coats include three colors: black, red and white. Only large patches count as calico. The black patches range from jet black to warm seal. The red patches may appear bright, dark or softly shaded. White areas are usually pure and crisp. The patch placement is random. No two calico British Shorthairs ever look the same.
Eye Color
Most calico British Shorthair cats have copper, gold or deep orange eyes. Kittens begin with blue eyes which transition to their adult shade between 8 and 16 weeks. Rare eye colors, such as hazel or odd eyed combinations, can occur but are not the standard.
Body Type
Calico British Shorthairs share the classic British build. They have a round head, thick bone, plush coat, dense structure, wide cheeks and a powerful body. Patch distribution does not affect coat texture or density.
Are Calico British Shorthairs Rare
Calico is rare in the British Shorthair breed. It requires very specific genetics and is far less common than blue, lilac or golden. Almost all calico British Shorthairs are female, making male calicos exceptionally rare.
Calico British Shorthair Color Development Timeline (Birth to 2 Years)
Newborn Stage
Newborn calico kittens show two clear dark and red tones with small white areas. Patches may appear smaller and less defined at birth.
3 to 6 Weeks
Color patches begin to separate and define. The red brightens. White areas become more obvious.
8 to 12 Weeks
The pattern becomes clear enough for buyers to see the adult layout. Kittens may still have soft ticking that disappears as they mature.
6 to 12 Months
The black and red deepen. The white stays crisp. The final pattern becomes more visually balanced.
12 to 24 Months
Full adult coat density arrives. Patches appear more contrasted and bold.
Indoor vs Sunlight Color Differences
Sunlight enhances the contrast of the red patches. Indoor light softens the pattern. Black areas may appear warmer under artificial light.
Genetics Behind the Calico Coat
What Genes Create Calico
Calico requires:
- A black based gene (B)
- A red based gene (O)
- White spotting gene (S)
The black and red genes occur on the X chromosome. Females have two X chromosomes which allows the random activation needed for calico patterning. This is called X inactivation or lyonization.
Simple Inheritance Examples
- A black female carrying red can produce calico kittens.
- A red male paired with a black female can produce calico females.
- Two non red parents cannot produce red or calico.
Why Calico Cats Are Harder to Produce
Calico only occurs when the correct color genes, sex chromosome combination and white spotting gene align. Many breeding pairs will never produce calico even if both carry the potential behind the scenes.
How to Identify a True Calico British Shorthair
A true calico has:
- Three clearly separate colors
- Distinct black patches
- Distinct red patches
- Crisp white areas
Not calico:
- Tortoiseshell cats with minimal white
- Mottled tricolor coats with no clear patches
- Mink or sepia tricolors
- Shaded or smoke patterns mistaken for white
Calico British Shorthair Kittens
What Calico Kittens Look Like at Birth
Newborn calico British Shorthair kittens show early hints of their black, red and white patches, but the pattern is not sharply defined at this stage. The red areas often appear darker or more muted, making it difficult to predict their final brightness. The white regions are usually visible at birth, but the overall contrast between colors develops over time.
How Their Color Changes as They Grow
As calico kittens grow, the red patches brighten and take on their true warm tone. The black areas deepen noticeably, creating richer contrast with the surrounding white. Patch boundaries become more defined with age, giving the kitten a clearer and more balanced tricolor appearance.
Eye Color Progression in Kittens
All British Shorthair kittens, including calicos, start life with soft blue eyes. These eyes gradually shift between eight and sixteen weeks, moving from blue to gold, deep gold or copper. Final eye color stabilizes around maturity, although slight changes in depth can continue through the first year.
How Temperament Develops
Calico British Shorthair kittens grow into the same calm and even tempered companions the breed is known for. They are gentle, people oriented and naturally steady, making them well suited for families and relaxed households. The calico pattern does not affect personality, and each kitten develops temperament based on breeding, handling and socialization.
Price Range for Calico British Shorthair Kittens
Calico British Shorthair kittens typically cost between $2,500 and $4,000 in the United States, making them one of the higher priced British Shorthair colors due to rarity. This pattern does not appear in every litter, and many breeders only produce one or two calicos across an entire season. Because the calico pattern requires specific genetics and almost all calicos are female, demand greatly outweighs supply.
Pet quality calico kittens often cost more than blue, lilac or black kittens from the same breeder. Show quality calicos with balanced, well placed patches may be priced at the upper end of the range. Breeding quality calicos are extremely limited since most programs retain their best females.
Factors influencing the price include:
- Higher pet prices than common colors
- High demand for the tricolor pattern
- Limited availability in most litters
- Patch clarity and color balance
- Health tested parents and registration
- Breeder reputation and structure quality
Most families who want a calico British Shorthair join a waitlist. True calico kittens are not consistently produced and often reserve immediately when announced.
How Reputable Breeders Raise Calico Kittens
Calico British Shorthair kittens are rare, which makes it even more important to work with a responsible breeder who focuses on health, structure and proper development rather than just color. Ethical breeders never mass produce calico kittens because the pattern cannot be guaranteed. Instead, they prioritize strong bloodlines, genetic diversity and correct British Shorthair type so that any calico kittens produced are healthy, well balanced and raised to the highest standard.
Expect reputable breeders to provide:
- Health tested parents screened for heart, kidney and genetic conditions
- TICA or CFA registration to verify lineage and authenticity
- Strong British Shorthair structure, including round head, thick bone and dense coat
- In home socialization that teaches kittens confidence and gentle manners
- Veterinary care, vaccinations and health records
- Microchipping for permanent identification
- Early temperament evaluation to match kittens with the right homes
Even though calico British Shorthair kittens are not available year round, we raise all our kittens with the same high standards listed above. If you are searching for a quality raised British kitten visit our kitten page for more info.
Grooming and Care for Calico British Shorthair Cats
Calico British Shorthair cats have the same dense double coat as all British Shorthairs, so consistent grooming helps maintain thickness and shine. A weekly brushing session is usually enough to remove loose hair and keep the coat looking full and even. Shedding increases seasonally, especially in spring and fall, so additional brushing during those times helps control loose hair and maintain crisp white areas.
Eye Care and Tear Stain Risks
Calicos do not have a higher natural risk of tear staining unless they carry specific bicolor patterns with large white facial areas. Cats with more white around the eyes may need gentle wiping to keep the area bright and clean. Regular checkups and proper diet support clear eyes and reduce the chance of mild staining in lighter colored cats.
Bathing and Grooming Tools
British Shorthairs generally do not require frequent bathing, but calicos benefit from occasional baths to keep white patches bright. A rubber curry brush, slicker brush and metal comb work well during heavy shedding seasons and help maintain healthy skin and coat. Using the right tools keeps the patches defined and prevents matting, even though the British coat rarely tangles.
Diet and Coat Quality
A high protein diet is important for maintaining coat density and overall health in British Shorthair cats. Adding natural omega 3 sources or supplements can enhance coat shine and bring out the contrast in the calico pattern. Proper hydration and balanced nutrition support healthy skin, consistent shedding and long term coat quality.
Temperament of a Calico British Shorthair
Calico British Shorthairs have the classic British temperament, which means they are steady, affectionate and easy to live with. They are known for quiet confidence rather than high energy behavior, and most settle comfortably into the daily routine of their home. Although some people believe calicos have a unique attitude or extra sass, this idea comes from folklore and does not apply to the British Shorthair breed.
Calico British Shorthairs are generally gentle, patient and observant, choosing to stay close to their people without demanding constant attention. They enjoy companionship and will follow family members from room to room, but they also appreciate having their own quiet resting spots. Many calicos show a soft, sweet loyalty and form strong bonds with their favorite person while still being friendly with the rest of the household.
These cats adapt well to quiet homes and also do well with respectful children who understand boundaries. They are not overly vocal and rarely act out to get attention. Their calm nature makes them suitable for busy professionals, families or first time cat owners who want a relaxed and stable companion. Color never affects personality, so calico British Shorthairs behave the same as blues, lilacs or any other color within the breed.
How Rare Is the Calico British Shorthair
Breeding Difficulty
Calico is genetically complex and appears less frequently in litters than solid or tabby colors.
Availability in the US vs Europe
Calicos are more common in Europe due to larger breeding populations but still considered uncommon.

Common Myths About Calico British Shorthair Cats
Myth 1: Calico British Shorthairs are always female.
Snippet: Almost all calicos are female, but rare male calicos do exist due to genetic exceptions.
Female cats have two X chromosomes, which allows both black and red to appear on the coat. Male cats normally have only one X chromosome, so they cannot express both colors. Male calicos occur only when a kitten inherits an extra X chromosome. These males are extremely rare and typically sterile, but they do prove that calico males can exist.
Myth 2: Calico cats have unique or difficult personalities.
Snippet: Calico British Shorthairs behave like any British Shorthair, not like a separate personality type.
The idea that calicos are spicy or moody is folklore, not genetics. Personality is controlled by breed temperament, socialization and individual traits. British Shorthairs are known for calm, gentle and stable behavior, and calicos follow the same temperament expectations.
Myth 3: Calico is a breed.
Snippet: Calico is a coat pattern, not a breed or sub breed.
Many people mistakenly think calico cats belong to a distinct breed. Calico is simply a tricolor pattern involving black, red and white. British Shorthairs, Persians, Maine Coons and many other breeds can all be calico. The pattern does not change the breed’s structure, pedigree or standards.
Myth 4: Calico kittens stay the same color throughout life.
Snippet: Calico kittens develop deeper, clearer patches as they grow and mature.
At birth calicos may look muted, patchy or uneven. Over the first few months, the black deepens, the red brightens and the white becomes more defined. Full contrast does not appear until six to twelve months, and density continues to improve through the second year.
Myth 5: Calico cats fade with age.
Snippet: Calico patches may soften slightly over years, but true fading is uncommon.
Changes in density or sun exposure can alter how bright the patches appear. Mature British Shorthairs develop thicker coats that sometimes blur patch edges. The core pattern remains stable throughout life.
Myth 6: Calicos are always high white.
Snippet: Calicos can have low white, medium white or high white patterns depending on genetics.
The amount of white depends on how the white spotting gene expresses in the kitten. Some calicos have only a few white patches while others are nearly half white. All three color levels are valid for the calico pattern.
Myth 7: Any tricolor cat is a calico.
Snippet: True calicos require clear patches of black, red and white, not mixed or smudged color areas.
Tortoiseshells with small amounts of white are not calicos. Tricolor tabbies with patterned stripes instead of solid patches are also not calicos. Calicos must show crisp separation between the three colors.
Myth 8: Calico British Shorthairs are more expensive because they are rare.
Snippet: Rarity contributes to price, but structure, health and breeder quality matter more.
A calico British Shorthair from a low quality breeder may cost less than a blue from a reputable program. Prices reflect pedigree, health testing, breeder ethics and demand, not simply color alone.
Myth 9: Male calico British Shorthairs can be used for breeding.
Snippet: Male calicos are almost always sterile due to their chromosome structure.
A male calico typically has XXY chromosomes rather than XY. This genetic arrangement prevents normal fertility. Even if a male calico appears outwardly healthy, he is unlikely to produce offspring.
Myth 10: Calico British Shorthairs require special diet or care.
Snippet: Calicos need the same care as any British Shorthair.
There are no nutritional or grooming requirements linked specifically to the calico pattern. All British Shorthairs benefit from a balanced diet, regular brushing and routine veterinary care. White areas may need light trimming or cleaning in some individuals.
Myth 11: Calico British Shorthairs can be predicted easily in litters.
Snippet: Producing calico kittens is genetically unpredictable and cannot be guaranteed.
Even when both parents carry the needed genes, calico expression requires several separate genetic components working together. Breeders cannot promise calico kittens in any litter. They occur when color genetics, white spotting and sex chromosome combinations align.
Myth 12: Calicos are more vocal or demanding.
Snippet: Calicos are not more talkative or needy than other British Shorthairs.
British Shorthairs are naturally quiet and independent. Calicos follow the same temperament. Their vocal habits and social preferences match the breed standard, not their color.
Myth 13: Calico British Shorthairs are more likely to be overweight.
Snippet: Weight gain is related to activity level and diet, not coat pattern.
British Shorthairs tend to have round, sturdy builds that look fuller than many breeds. Maintaining a healthy diet and play routine is the key to preventing weight gain. Calico coloring plays no role in body mass.
Myth 14: Calico British Shorthairs are a sign of good luck.
Snippet: Calico luck legends exist in many cultures, but they are symbolic rather than genetic.
Historic traditions in Japan, Europe and the United States associate calicos with prosperity and protection. While charming, these beliefs are cultural stories rather than biological traits.
Myth 15: Calicos are always patched tabbies.
Snippet: Calicos can have solid patches or tabby patches depending on genetics.
When the black or red patches carry the tabby gene, the calico becomes a torbie and white. When the patches are solid, the cat is simply calico. Both patterns are accepted and equally authentic.
Myth 16: All calicos have the same pattern layout.
Snippet: Every calico is unique because patch placement is random and unpredictable.
No two calico British Shorthairs ever share the same markings. Patch size, color balance and white distribution differ widely. This individuality is one of the reasons calicos are so visually striking.
Myth 17: Calico British Shorthairs cannot compete in shows.
Snippet: Calicos are fully showable in bicolor or tricolor classes in all major cat registries.
As long as the pattern meets the registry rules for clarity and proportion, calico British Shorthairs can be shown. Structure, head type and coat quality matter more in the show ring than color placement.
Myth 18: Calicos are harder to socialize.
Snippet: Socialization depends on the breeder and environment, not the coat pattern.
Healthy, well raised British Shorthair kittens learn confidence through handling, exposure and routine. Calico kittens that grow up in home based environments are just as friendly and well adjusted as solid or tabby kittens.
Myth 19: Calico British Shorthairs require more brushing.
Snippet: Calicos shed the same amount as other British Shorthair colors.
You may notice more shedding from the white areas because the hairs are more visible, but total shedding volume is the same. Weekly brushing is usually enough to maintain coat health.
Myth 20: Calicos are a guarantee of a rare or high value pedigree.
Snippet: Color alone never determines pedigree quality.
A calico kitten may come from a modest lineage or from a top show line. The pattern itself does not prove anything about the cat’s structure, health or ancestry. Evaluating pedigree, registration and health testing is always essential.

Full FAQ About Calico British Shorthair Cats
1. Are calico British Shorthair cats rare
Yes. Calico British Shorthair cats are considered rare because the pattern requires a combination of black, red and white genes that only align in certain breeding pairs. Since most calico cats are female due to X linked genetics, litters produce very few calicos each year. Many breeders may only see one or two in several seasons.
2. How much do calico British Shorthair kittens cost
Calico British Shorthair kittens usually cost more than standard colors such as blue or lilac. Their price reflects the rarity of the pattern, the difficulty of producing correct patches and the fact that demand is higher than supply. Expect prices to be in the upper range of British Shorthair kittens depending on breeder quality, pedigree and region.
3. Can a male British Shorthair be calico
It is possible but extremely rare. Male calico British Shorthairs occur only when a male kitten inherits an uncommon genetic condition where he receives two X chromosomes and one Y chromosome. These males are typically sterile and appear only once in many litters. They are considered biological exceptions, not standard breeders.
4. Do calico British Shorthair kittens change color as they grow
Yes. Calico kittens often show softer or smaller patches at birth. As they grow, the black and red patches become more defined and the white areas become brighter. Most calicos reach their final pattern clarity between six and twelve months. Patches stay the same basic layout but deepen in tone and contrast.
5. Are calico British Shorthair cats good pets
Calico British Shorthairs have the same temperament as all British Shorthairs. They are calm, affectionate, observant and steady. They enjoy being near their families while still being independent. Color does not influence personality. If you love the classic British temperament, a calico will be an excellent companion.
6. Do calico British Shorthair cats have health issues related to color
Calico coloring itself does not cause health problems. However, the extremely rare male calico may be sterile because of the extra X chromosome. Female calicos have no health risks tied to the pattern. Good breeding practices and health testing are more important than color when evaluating long term health.
7. Do calico British Shorthairs have more attitude
No. The idea that calicos have special personality traits is a myth. Their behavior is determined by breed temperament, socialization and individual personality, not their color or pattern. Calico British Shorthairs are just as gentle and even tempered as blue, lilac or golden cats.
8. Do calico British Shorthairs shed more than other colors
Shedding levels are the same across all colors. British Shorthairs have a dense double coat that sheds lightly year round with heavier shedding in spring and fall. Regular brushing helps maintain the calico coat and keeps the white areas bright.
9. What eye color do calico British Shorthair cats have
Most calico British Shorthairs have gold, deep gold or copper eyes. Kittens start with soft blue eyes and begin transitioning between eight and sixteen weeks. Rare eye colors such as hazel or green tinted copper can appear but are not standard.
10. Are calico British Shorthair kittens born with white patches
Yes. White is a key part of the calico pattern and appears from birth. The amount of white can range from small amounts to large body wide areas depending on the kitten’s genetic expression of the white spotting gene.
11. Can two non calico parents produce a calico British Shorthair
Yes, if both parents carry the genetic components needed for calico. This includes black based genetics, red based genetics and the white spotting gene. Color genetics can be hidden for generations, so calico may appear unexpectedly even if neither parent is visibly calico.
12. Is calico considered a showable pattern in British Shorthairs
Yes. Calico is a recognized and showable pattern in CFA and TICA under the bicolor category. However, each registry has rules on pattern clarity, patch definition and color separation. Not all calico kittens will develop into show quality adults.
13. Why are calicos almost always female
Calico coloring requires both black and red genes which are located on the X chromosome. Female cats have two X chromosomes, which allows both colors to appear on the coat. Males have only one X chromosome, so they rarely express both colors unless they carry an uncommon genetic anomaly.
14. Do calico British Shorthairs require special grooming
Calicos do not need special grooming compared to other colors. Their coat care is the same as any British Shorthair. However, areas of white may require a bit more brushing or wiping to stay bright. A high quality diet also helps maintain contrast.
15. Can calico British Shorthair cats have tabby patches
Yes. Calico patches can be either solid or tabby. When the red or black patches include tabby stripes, the cat is called a patched tabby or torbie and white. Both are acceptable patterns in British Shorthairs and often create very striking designs.
16. Are calico British Shorthairs more expensive than tortoiseshells
Generally yes. Calicos typically cost more because they require the white spotting gene in addition to black and red coloration. They are less common, especially in structured breeding programs aimed at producing correct patch definition.
17. Are calico British Shorthair cats friendly with children
Yes. British Shorthairs are known for their stability and calm temperament. Calicos are no different. They adapt well to family homes, enjoy quiet company and typically tolerate respectful children. Their temperament is predictable and steady.
18. Do calico British Shorthair cats stay small
No. British Shorthairs are a round and solid breed. Calicos grow to the same adult size as other colors. Females tend to be slightly smaller than males, but this is due to sex, not color. Expect a sturdy, medium to large build.
19. Can calico British Shorthair cats be longhaired
Yes. When two carriers of the longhair gene are paired, calico longhair British Shorthairs can appear. These cats have the same pattern but with a plush semilong coat similar to a British Longhair. They are exceptionally beautiful and rare.
20. How can you tell if a calico kitten will have a balanced pattern
By eight to twelve weeks most calico kittens show clear patch placement. Balanced calicos have distinct color areas on both sides of the body and good separation between black and red segments. Pattern clarity improves with age but the basic structure is visible early.
