The Cornish Rex is a true showstopper with their slender build, large ears, and curly, soft coat. That coat is one of the things that makes this breed so special: Their velvety fur feels like nothing else. And while they may appear slender, they’re known for being quite muscular and athletic, which makes them great at jumping and running, which they love to do. These cats are always on the go, so they make great companions for active owners who enjoy playing. Despite their active natures, these cats are also extremely affectionate and social with their humans. The Cornish Rex has a unique history, as the breed is believed to have originated in Cornwall, England, where a cat with curly hair was born as a result of a genetic mutation. Today, they are popular pets around the world and are loved for their charming personalities and distinct appearance. So, if you’re looking for a playful and affectionate companion, a Cornish Rex might just be the perfect cat for you!

Where are Cornish Rex cats from?

Cornish Rexes originate from Cornwall, England. In 1950, a single curly-coated kitten was born to an unexpected cat litter. This unusual kitten was bred back to their mother and helped establish a breed of curly-coated cats with lithe bodies. Other breeds, such as the Siamese, British Shorthair, and Burmese, were later bred in to diversify their gene pool.

When does a Cornish Rex stop growing?

Most Cornish Rex cats will stop growing and reach their full size when they are between nine and 12 months old. If you’re worried about your Cornish Rex’s growth, it’s always best to chat with your vet. They can help you monitor your cat’s growth and development and make sure they are on track.

How long do Cornish Rex cats live?

The average lifespan of a Cornish Rex cat is between 15 and 20 years. However, there can be some variation depending on genetics, diet, lifestyle, and neuter status. Maintaining a healthy lifestyle plays a critical role in ensuring a Cornish Rex reaches their potential by avoiding health problems and accidents.

Cornish Rex temperament

Learn about about the Cornish Rex temperament and how well they fit into your lifestyle, home environment, and family.

Do Cornish Rex cats meow a lot?

Yes, Cornish Rex cats tend to meow more than other breeds, perhaps due to their Siamese roots. While not all Rexes are super vocal, there’s always a chance your Cornish Rex might be a talkative kitty. They might meow to greet you, ask for attention, or simply chat about their day.

Are Cornish Rex cats friendly?

Yes, Cornish Rexes are friendly, affectionate, and outgoing cats. They adore people and thrive on companionship. Rexes tend to be very social kitties and often follow their humans around the house, seeking interaction and maybe a few scratches.

Are Cornish Rex cats good with other cats?

Yes, most Cornish Rexes get along with other cats. But like any cat, Cornish Rex cats have individual personalities, so some might prefer solitude. With proper introductions and a good match in temperament, Cornish Rex cats can be great companions for other felines.

Are Cornish Rex cats good with dogs?

Yes, Cornish Rex cats can be good in homes with dogs. Their energy level can keep up with a playful pup, and they might even enjoy chasing each other around the house. Proper introductions are crucial for both the Cornish Rex and the dog. Slow intros help them get accustomed to each other’s company in a safe and controlled way.

Are Cornish Rex cats good hunters?

Yes, Cornish Rexes are quite capable of hunting mice, but it depends on the individual cat and the situation. Not all Cornish Rex will be equally motivated to hunt. Some might be more interested in play or cuddles than chasing mice. So, don’t rely on them solely for pest control, but you might be surprised by their skills.

Are Cornish Rex cats good indoor cats?

Yes, Cornish Rex cats make great indoor cats. For safety reasons, the American Veterinary Medical Association (AVMA) recommends that all cats be kept indoors. Indoor kitties have a decreased risk of fleas, parasites, infections, and trauma.

Are Cornish Rex cats active?

Yes, Cornish Rex cats are very active. They are energetic cats who play hard, and they can be dog-like in their love of fetch. They’re also keen on jumping and climbing to out-of-reach places.

Are Cornish Rex cats good lap-cats?

Yes, Cornish Rexes are very good lap-cats. These kitties love a warm lap and will seek out attention. Cornish Rex cats generally relish cuddling and closeness, unlike some cats who might tolerate being petted but prefer some personal space.

Cornish Rex health

Learn about about the Cornish Rex health outlook and what diseases they may be prone to at various stages of their life.

Do Cornish Rex cats shed?

Yes, Cornish Rex cats shed, but minimally. Because they have only a single coat (and a fine, silky, usually curly one at that), they are low-shedding cats. Because of their genetic makeup, Rexes do not have the longer and coarser outer guard hair seen in most cats.

Do you need to groom a Cornish Rex cat?

Yes, all cats, including Cornish Rexes, need basic grooming. But beware: excessive brushing will damage a Cornish Rex’s fragile coat, so only brush them when necessary. All cats should have their claws trimmed every two weeks or so. Cats are also prone to periodontal disease and should have their teeth brushed two to three times a week.

Are Cornish Rex cats hypoallergenic?

Yes, Cornish Rex cats are considered hypoallergenic. However, the term “hypoallergenic” is used loosely: there is no truly hypoallergenic cat breed. All cats, regardless of hair length or coat type, produce allergy-inducing dander in their skin, saliva, and urine. That said, Cornish Rex cats can be a good option for people with mild cat allergies because they shed much less than many other breeds. There’s no guarantee a Cornish Rex won’t trigger allergies. While someone with allergies might find a Cornish Rex manageable, others might still experience reactions.

Are Cornish Rex cats healthy?

The Cornish Rex is mostly a healthy breed, though their thin coat can cause some issues, including:

  • Dry skin and itchiness: The lack of guard hairs can leave this breed’s skin exposed and susceptible to dryness and irritation.

  • Yeast infections: Skin folds and a lack of overcoat can trap moisture, creating an environment for yeast overgrowth. 

  • Sun damage: Cornish Rexes are prone to sun damage due to their thin coat, and bald spots can arise

What diseases are Cornish Rex prone to?

Like many breeds, Cornish Rex can be susceptible to certain inherited conditions, such as:

  • Hypertrophic cardiomyopathy (HCM): HCM is an abnormal thickening of the left ventricle of the heart that leads to improper blood flow. It is the most common cause of heart disease in cats and can result in sudden death.

  • Patellar luxation: Also known as slipped kneecaps, patellar luxation occurs when slight abnormalities cause the knee joint to slide in and out of place. This can cause pain and occasional lameness. Surgical treatment is available for severe cases, although many cats lead normal lives without treatment.

  • Chronic kidney disease (CKD): This is a common condition in cats in which the kidneys gradually lose function over time, leading to issues such as dehydration, weight loss, and increased thirst and urination. It’s often managed through diet, medication, and regular check-ups to maintain quality of life.

  • Diabetes: This complex disease prevents the body from properly regulating blood sugar levels

  • Hyperthyroidism: This thyroid malfunction results in an overproduction of thyroid hormone and could cause weight loss, excessive thirst, panting, diarrhea, and obesity.

  • Gingivitis: This inflammation of the gums can lead to periodontal disease.

  • Obesity: Cats have a hearty appetite and are prone to obesity. It is best to give them scheduled feeds and minimal treats.
