Cornish Rex

Quick Facts

The Cornish Rex has a unique soft, wavy coat with almost no guard hairs, which makes it feel like crushed velvet to the touch.
This is one of the most active and playful cat breeds, often compared to a kitten that never really grows up.
Cornish Rex cats are very people focused and usually prefer being involved in every part of household life rather than sitting on the sidelines.
Their slender, fine‑boned body, large ears, and egg‑shaped head give them a very distinctive and elegant appearance.
Despite the short coat, they are not maintenance free and need thoughtful care around temperature, nutrition, and mental stimulation.

Appearance & Coat

The Cornish Rex is a striking and unmistakable cat. At first glance you notice the long, fine‑boned body and those huge, alert ears that sit high on an egg‑shaped head. The overall impression is one of elegance combined with surprising strength. They are medium in size, but their light build can make them look smaller than they actually are on the scale. Adults are usually lean yet muscular, similar to an athlete rather than a heavy set cat.

The body is long and supple, with a deep chest and a noticeable waist. The back often has a gentle arch which emphasizes their graceful outline. Legs are long and slim, with the hind legs a little longer than the forelegs. This gives the Cornish Rex a powerful spring when they jump or run. The paws are small and oval, which adds to their delicate look. The tail is long, thin, and well covered with waves of fur, often curling slightly when the cat is relaxed.

The head is one of the breed’s most famous features. It is often described as egg‑shaped when viewed from the front, with a narrow muzzle and high cheekbones. The profile should show a straight nose and a gently rounded forehead. Large, oval eyes give a bright, curious expression, and coat color usually matches the eye color family, such as golden or green shades, depending on the pattern and variety.

The Cornish Rex coat is what truly sets this breed apart. Unlike most cats, they almost lack coarse guard hairs. Instead, they have a short coat made mostly of soft undercoat. The hair lies close to the body in waves and ripples, which may be tighter on some cats and looser on others. Even the whiskers can be curly or crinkled. When you stroke a Cornish Rex, the coat feels incredibly soft, often compared to silk, velvet, or a plush toy.

In terms of color and pattern, the Cornish Rex is very inclusive. You can find them in almost every color and pattern that exists in cats, including solid, bicolor, tabby, tortie, smoke, and more. There are also pointed varieties in some registries. This wide range means that future owners can choose a Cornish Rex in a look that suits their taste, while still enjoying the same basic temperament and coat structure.

Coat care is simple but not completely hands off. Regular brushing with a soft, rubber grooming glove or a very gentle bristle brush once or twice a week is usually enough. The goal is to remove loose hairs and distribute skin oils without roughing up the delicate coat. Avoid heavy combs or harsh brushing, since this can break the fine hairs or irritate the skin. Because of their lack of dense guard hairs, Cornish Rex cats may appear somewhat greasy if not occasionally wiped down with a warm, slightly damp cloth. Many do not need full baths often, but some lines have a bit oilier skin and benefit from a mild shampoo every few months.

One important practical issue is temperature. The thin coat provides less insulation than in most breeds. Many Cornish Rex cats love to sit in sunny windows, curl under blankets, or sleep on warm laps. They should live indoors, in a stable climate, and they may need extra warmth in colder seasons. Heated beds, soft blankets, and draft free sleeping spots will help them stay comfortable and healthy. Owners should also be aware that the thin coat provides less protection against scratches, so rough outdoor life is not ideal.

With good care, the Cornish Rex coat remains one of the most enjoyable features of the breed. The combination of unique texture, minimal shedding compared to many other cats, and low grooming time makes them a practical choice for people who enjoy close, hands on interaction with their pets.

Temperament & Personality

Living with a Cornish Rex is a bit like sharing your home with a curious, playful child who never loses interest in life. This breed is extremely people oriented and often forms very strong bonds with its human family. Many owners report that their Cornish Rex follows them from room to room, participates in every activity, and insists on being included in conversations, phone calls, and meetings. They are not the type of cat who is content to be admired from across the room. Instead they usually want to be right on your lap, on your shoulder, or at least within touching distance.

Cornish Rex cats are typically very affectionate. They enjoy being stroked, cuddled, and talked to, and many love to sleep under the covers with their favorite person. Because they are social, they do not usually enjoy long hours left alone with nothing to do. Families, couples, or individuals who work from home often suit them better than a household where the cat would be alone all day. If you are away often, consider a second friendly cat for company, or plan interactive toys and puzzle feeders to keep your Cornish Rex busy.

They are well known for being playful and active, often well into adulthood and even into senior years. Many Cornish Rex cats will learn to fetch small toys, run after ping pong balls, and perform leaps and twists that look almost acrobatic. They can be very entertaining, but the energy level may surprise people who are used to more sedate breeds. This high activity can be a joy, but it can also be a challenge if the environment is not prepared for a lively cat that loves to climb, explore, and test boundaries.

With children, the Cornish Rex is often patient and tolerant, provided the children are taught to handle the cat gently. Their playful nature means they usually enjoy games with respectful kids, such as tossing a toy or using a teaser wand. Supervision is important with younger children, both to protect the cat’s fine body from falls and rough handling, and to prevent the child from being scratched in self defense if the cat feels trapped. In a calm and respectful household, Cornish Rex cats can become wonderful companions and even best friends with the children.

With other pets, the Cornish Rex is usually sociable and curious. They often get along well with other cats and can adapt to living with cat friendly dogs. In many homes, they will try to establish themselves at the center of the group, both in terms of play and human attention. Proper introductions are essential, especially with more reserved cats or older animals who are not used to such an enthusiastic personality. A slow, stepwise introduction helps reduce stress and avoids conflict.

There are a few common temperament related challenges to keep in mind:

Vocalization. Many Cornish Rex cats are talkative. They may meow to get attention, ask for food, or simply respond when you speak to them.
Need for interaction. A bored Cornish Rex can become demanding. They may get into cupboards, chew on unsuitable items, or pester other pets if they do not have enough constructive outlets.
Strong attachment. Their loving nature is a gift, but it can also make them more vulnerable to stress if routines change, if they lose a companion, or if they are rehomed.

Overall, the Cornish Rex personality suits people who enjoy an active, companionable cat that behaves almost like a small dog in terms of loyalty and desire for involvement. If you are looking for a quiet, decorative cat that mostly sleeps and keeps to itself, this is probably not the right breed. If you want a lively, affectionate partner in daily life, the Cornish Rex can be an outstanding choice.

Training & Exercise

The Cornish Rex is not only playful and energetic, but also intelligent and trainable. This is a breed that thrives on mental as well as physical stimulation. If you provide both, you will have a happier cat and far fewer behavior problems.

When it comes to exercise, think in terms of interactive play sessions several times a day rather than one long workout. Short, intense bursts of activity are natural for cats. A Cornish Rex in particular loves games that simulate hunting. Feather wands, fishing rod toys, and fast moving teasers are ideal. Many will jump high into the air, twist their bodies, and sprint around the room to catch their “prey.” Rotate toys frequently so that your cat does not become bored. Simple items like paper balls, bottle caps, or cardboard tunnels can also become favorites.

Vertical space is very important. Cornish Rex cats usually enjoy climbing, perching, and surveying their territory from above. Invest in at least one sturdy cat tree or multi level scratching tower. Place it near a window if possible, so the cat can watch birds and outdoor life. Wall mounted shelves and cat bridges offer additional climbing routes that help burn energy and satisfy their curiosity. Scratching posts of different textures support natural scratching behavior and protect your furniture.

Training a Cornish Rex can be surprisingly rewarding. They tend to be food motivated and eager to interact, which makes them good candidates for clicker training. You can teach basic behaviors such as:

Coming when called by name
Sitting on cue
Giving a high five or paw
Jumping onto a designated perch
Walking nicely into a carrier

Training should always be based on positive reinforcement. Use small, high value treats such as tiny bits of cooked chicken, freeze dried meat, or commercial training treats. Pair the desired behavior with a click or a short marker word and then reward immediately. Keep sessions short, usually 5 to 10 minutes, and end while your cat is still interested. In time, you can add simple trick routines that provide both entertainment and mental challenge.

Litter box training is usually straightforward with this breed, but they can be sensitive to a dirty box or strong smells. A clean, easily accessible litter tray in a quiet area will prevent most problems. If your Cornish Rex suddenly stops using the box, always rule out medical issues through a vet visit before assuming it is behavioral.

Because they are intelligent, Cornish Rex cats can develop unwanted habits if their environment is not enriching. For example, they might learn to open cabinet doors, jump on counters, or chew plants. Instead of only trying to prevent these behaviors, focus on offering acceptable alternatives and guiding the cat toward them. For instance, provide puzzle feeders so the cat works for part of their food. Food dispensing balls, treat mazes, and interactive feeders occupy their mind and slow down fast eaters.

Leash training is another option that some Cornish Rex cats enjoy. Using a well fitted harness and a gradual introduction, many can learn to walk confidently in safe, quiet areas. This can be especially useful in apartments where outdoor access is limited, although care must be taken with temperature and overexposure to cold or strong sun, due to their short coat.

The key to training and exercise with a Cornish Rex is consistency. Daily attention, regular play routines, clear boundaries, and patient positive training create a strong bond and a well behaved, confident cat. Without this structure, the same intelligence and energy that make them such charming companions can turn into mischief. For active households who enjoy engaging with their pets, these cats are an endless source of fun and shared activities.

Health

The Cornish Rex is generally considered a healthy and robust breed, but like all purebred cats, they have certain health concerns that responsible owners and breeders should be aware of. A combination of careful breeding, regular veterinary care, and good daily management helps maintain their wellbeing and quality of life.

One area of particular interest in Cornish Rex cats is heart health. Hypertrophic cardiomyopathy, often shortened to HCM, is the most common form of heart disease in cats and can occur in this breed. Ethical breeders work actively to reduce the risk by screening breeding animals with echocardiography performed by experienced veterinary cardiologists. For pet owners, it is wise to discuss heart screening with your vet, especially if your cat has any symptoms such as rapid breathing, lethargy, or fainting episodes, or if you know of HCM in close relatives.

Another health topic is the skeletal system. Some pedigrees in different breeds are known to have genetic bone conditions, and although the Cornish Rex is not among the worst affected, careful breeders pay attention to overall body structure and avoid breeding animals with obvious deformities. Good nutrition during growth, controlled weight, and safe physical activity all support strong bones and joints.

Because of the unique coat structure, Cornish Rex cats can have specific skin considerations. Their thin coat and reduced guard hairs may lead to:

Slightly oilier skin in some individuals, with potential for blackheads or mild irritation
Increased sensitivity to sun, with a higher risk of sunburn on ears and nose
Greater awareness of scratches and minor injuries, since there is less protective hair

Regular gentle grooming, as described earlier, along with careful monitoring of the skin, helps detect problems early. Avoid strong shampoos and aggressive scrubbing, which can strip natural oils and cause dryness or irritation. If you see persistent redness, flaking, or sores, seek veterinary advice.

Some Cornish Rex cats have sensitive digestion. A high quality, balanced diet that is appropriate for the cat’s age and activity level is essential. Introduce new foods gradually and limit sudden diet changes, which can upset the stomach. If you notice chronic loose stools, vomiting, or poor coat condition, consult your vet rather than experimenting with random diets or supplements.

Respiratory health is another area to consider. While the Cornish Rex is not known for severe brachycephalic issues like some flat faced breeds, they can still be susceptible to common feline respiratory infections, especially as kittens. Vaccination according to your vet’s recommendations, along with good hygiene and quarantine procedures in multi cat homes or catteries, will reduce risks.

Routine preventive care should include:

Vaccinations against core feline diseases
Regular deworming and parasite control tailored to your cat’s lifestyle
Annual or semi annual veterinary checkups, including dental assessments
Weight monitoring to avoid obesity, which can strain joints and organs

Dental health is often overlooked, but dental disease is common in cats in general. Provide dental friendly diets or approved dental treats when recommended by your vet, and consider tooth brushing if your cat accepts it. Early dental care can prevent extractions and pain later in life.

The typical lifespan of a well cared for Cornish Rex is often around 12 to 15 years, and some live even longer. Genetics, environment, and healthcare all play roles. Responsible breeders usually screen for known concerns in their lines and may provide information on recommended tests such as:

Heart ultrasound screening for HCM in breeding animals
General veterinary health checks before breeding
Genetic tests that may be relevant in specific lineages

For pet owners, choosing a kitten or adult from a breeder who prioritizes health, or adopting from a shelter with good veterinary support, lays a strong foundation. Once your Cornish Rex is home, maintaining a healthy weight, offering a safe indoor environment, preventing stress, and visiting your vet regularly all help your cat stay healthy and happy over the long term.

History & Origins

The story of the Cornish Rex begins in Cornwall, in the south west of England, in the early 1950s. On a farm near Bodmin Moor, a domestic tortie and white cat gave birth to a litter that included one very unusual kitten. This male kitten had a fine, curly coat instead of the typical straight fur of his littermates. He was named Kallibunker and is considered the foundation of the Cornish Rex breed.

Early on, it became clear that Kallibunker’s curly coat was not a random accident but the result of a natural genetic mutation. Local cat enthusiasts and geneticists worked together to understand and preserve this new trait. They discovered that the curl was inherited as a recessive trait, which meant that both parents had to carry the gene for kittens to show the wavy coat. To build a sustainable breeding population, Kallibunker was mated back to his mother, and later to selected shorthaired cats from the area, including British Shorthairs and other local domestic cats. This established a small but growing line of curly coated cats that would eventually become the Cornish Rex.

The name “Rex” has an interesting background. It comes from a term used earlier for curly coated rabbits presented to a king’s show in Europe. When those rabbits did not meet the usual standard, they were labeled “Rex” as a way to accept them despite their unusual fur. The same word was later applied to curly coated cats, and the first recognized line from Cornwall became known as the Cornish Rex.

In the early days, another curly coated breed appeared independently in Devon, not far from Cornwall. That cat, later developed into the Devon Rex, had a different mutation and a different coat type. For a time, some breeders attempted to cross Cornish and Devon Rex cats in hopes of strengthening the curl. However, the kittens from such matings often had straight coats, and it became clear that the two mutations were separate and not compatible in the way initially hoped. Over time, the Cornish Rex and Devon Rex were developed as distinct breeds, each with its own standard and identity.

As interest grew, Cornish Rex cats were exported to other countries, including the United States and various parts of Europe. Breeders worked with cat associations to develop official breed standards that described the unique coat, slender body, and elegant head. Controlled outcrosses to other shorthaired breeds improved genetic diversity while preserving the characteristic curl and overall look. Through careful selection, the modern Cornish Rex gained its recognizable egg shaped head, large ears, and highly arched, rippled coat.

Today, the Cornish Rex is kept almost entirely as a companion and show cat. Their unusual appearance and affectionate nature have earned them a devoted following. At cat shows, Cornish Rex cats often attract attention not only from judges but also from visitors who want to feel the remarkable coat. Breeders continue to refine the breed according to the standards of major cat fancier organizations, while also focusing on health, temperament, and genetic diversity.

In everyday life, Cornish Rex cats live as beloved pets across the world. Many share their homes with children, other cats, and even dogs, and they are increasingly visible in social media and cat communities due to their playful character and photogenic look. Some participate in cat agility events or trick demonstrations, which suit their active and trainable nature.

Despite their relatively recent origin compared to ancient breeds, the Cornish Rex has a clear and well documented history. From a single farm kitten with an unexpected coat, the breed has grown into a recognized and cherished companion, known for its velvet waves, elegant build, and joyful personality.

Living with the Breed

Sharing your home with a Cornish Rex is both rewarding and demanding. This is not a cat you simply feed and admire from a distance. They expect to be a full member of the family, and they notice very quickly if they are ignored. Before you choose a Cornish Rex, it helps to understand what daily life with this breed looks like and the level of commitment involved.

The most important aspect is time and interaction. Cornish Rex cats thrive on human company. If you are often away from home for long periods, this breed may struggle, especially if it is the only cat in the household. A second compatible cat, or even a calm, cat friendly dog, can make a big difference, but they will still need regular engagement and playtime with you. Plan at least a few structured play sessions every day, plus casual contact such as lap time, grooming, and conversation.

Financially, the yearly costs of caring for a Cornish Rex are similar to those of other indoor pedigree cats, although vet bills can vary by region and individual health. You should budget for:

High quality food, either wet, dry, or a combination, suitable for an active cat
Routine veterinary care, including vaccinations, parasite control, and yearly checkups
Occasional dental cleaning under anesthesia if needed
Pet insurance or a savings fund for unexpected illnesses or accidents
Replacement of toys, scratching posts, and other enrichment items

Initial costs also include the purchase price from a responsible breeder or adoption fee, along with basic equipment such as:

A sturdy cat tree or climbing furniture
Several scratching posts or boards
Comfortable beds and soft blankets, preferably in warm, draft free spots
Food and water bowls, or a fountain for cats who like running water
A suitable litter box with a good quality litter that your cat accepts
Safe toys, including interactive wands, balls, and puzzle feeders
A secure carrier for vet visits and travel

Because of the Cornish Rex coat, environmental comfort is a constant consideration. They are indoor cats and should not be left outside in cold or wet weather. In cooler climates, they may seek heat sources such as radiators, laptop keyboards, or sunny windowsills. Provide warm resting places and be careful with very hot surfaces that could burn their skin. In hot sunny conditions, prevent prolonged direct sun exposure that might cause sunburn, especially on pale colored cats and exposed ear tips.

Household dynamics also matter. Cornish Rex cats often enjoy lively homes where people talk, move, and interact, but they can find very chaotic, noisy environments stressful if there is no safe quiet zone to retreat to. Provide hiding places, such as covered beds, boxes, or a quiet room, where your cat can rest undisturbed. Respect their signals when they want a break, even if they are usually very sociable.

New owners should be prepared for a certain level of mischief. The intelligence and curiosity of the Cornish Rex often leads them to test cupboards, shelves, and any new object that appears. You may find them exploring inside wardrobes, watching you cook from the kitchen counter, or trying to “help” with computer work. A sense of humor and a willingness to cat proof certain areas will go a long way. Keep breakable items out of reach, store toxic plants or cleaning products securely, and make sure windows and balconies are safe.

Grooming routines are relatively straightforward but should not be ignored. Even if they do not need daily brushing like some longhaired breeds, regular coat checks, ear cleaning if wax builds up, and nail clipping are part of responsible care. Many Cornish Rex cats tolerate these procedures well if introduced gently and associated with treats from a young age.

Emotionally, the bond with a Cornish Rex can be deep and rewarding. They often respond strongly to their human’s mood and enjoy being comforters when someone is ill or unhappy. At the same time, they can be sensitive to changes, such as moving home, a new baby, or loss of a companion. Maintaining routines and offering extra reassurance during transitions will help them cope.

For people who want a quiet, low involvement cat, the Cornish Rex may feel overwhelming. For those who are ready to invest time, energy, and affection, and who enjoy a lively, interactive relationship with their pet, living with a Cornish Rex can be one of the most enjoyable experiences in the cat world. With the right preparation, understanding, and care, these elegant, velvet coated clowns can become cherished family members for many years.

Frequently Asked Questions

Are Cornish Rex cats really hypoallergenic?

They are often better tolerated by some allergy sufferers because they shed less and have a very short, wavy coat. However, no cat is truly hypoallergenic, since most people react to skin and saliva proteins, not fur length. Spending time with the breed before adopting is the only reliable way to test your personal reaction.

What is the temperament of a Cornish Rex like?

This breed is typically active, people focused, and playful well into adulthood. They tend to enjoy interactive games, often follow their owners around the home, and may seek frequent physical contact. Many are vocal and expressive, which can be charming to some households and overwhelming to others.

Do Cornish Rex cats get cold easily because of their short coat?

Yes, they are more sensitive to temperature than many other cats due to their very fine, sparse coat. They usually prefer warm spots, heated beds, and sunny windowsills. Most should live strictly indoors, with extra care taken in colder climates to prevent chills and drafts.

How much grooming does a Cornish Rex need?

They require less brushing than most cats, but still benefit from gentle grooming to remove loose hairs and skin oils. Harsh brushing can damage the delicate curls, so a soft glove or hand smoothing is usually sufficient. Regular ear cleaning is often necessary, as their large ears can accumulate wax and debris.

Are Cornish Rex cats good with children and other pets?

They are usually sociable and playful, which can make them good companions for respectful children and friendly pets. Because they are active and people oriented, they generally enjoy interaction rather than a quiet, hands off lifestyle. Supervision and careful introductions are still important, as with any breed.

What health problems are Cornish Rex cats prone to?

The breed can be predisposed to certain issues such as hypertrophic cardiomyopathy (a heart disease), dental problems, and some hereditary muscle or neurological conditions in specific lines. Their delicate coat and skin may also be more prone to irritation or sunburn. Choosing a breeder who screens for known genetic and cardiac issues reduces risk.

Why does a Cornish Rex feel oily or need more frequent baths?

Because the coat is very short and lacks a typical guard hair layer, skin oils are not absorbed and distributed in the same way as in other cats. Some individuals develop a slightly greasy feel or visible buildup, especially on the tail or chin. Occasional gentle baths with a cat safe shampoo can help, but overbathing may dry the skin.

How active are Cornish Rex cats and how much playtime do they need?

They are among the more energetic and athletic cat breeds, often enjoying climbing, jumping, and running. Daily interactive play, puzzle feeders, and vertical spaces like cat trees help prevent boredom and destructive behavior. Many remain kittenlike in activity levels well into their senior years.

Is a Cornish Rex suitable for apartment living?

They generally adapt very well to smaller spaces as long as they receive enough mental and physical stimulation. Because of their social nature, they can become stressed if left alone for long periods with no interaction. Enrichment, companionship, and warm, cozy resting spots are more important than floor space.

What should I know about feeding a Cornish Rex and their slim, fine‑boned body?

They have a naturally lean, whippetlike build, so a healthy adult should look slim but muscular, not bony. Their high activity level can mean a slightly higher calorie need, but overfeeding can still lead to weight gain, which stresses their fine frame. A balanced, high quality diet and regular body condition checks with your veterinarian are recommended.
