Cornish Rex Breed History and Origins
The Cornish Rex originated in Cornwall, England, in 1950 when a spontaneous genetic mutation resulted in a curly-coated kitten named Kallibunker. This unique cat became the foundation of the breed. Breeders carefully selected for the signature wavy coat, large ears, and fine bone structure, leading to the development of the modern Cornish Rex. The breed gained recognition in 1963 and has since become a beloved pet worldwide for those seeking an affectionate and energetic companion.

Their playful and curious nature means they remain kitten-like throughout their lives, always up for a game or a new adventure. While they are known to be vocal, their voices are usually soft and engaging rather than loud. Cornish Rexes thrive in homes where they receive plenty of attention and mental stimulation.

Key Characteristics of Cornish Rex Cats

Their most distinctive feature is their short, soft, wavy coat, which lacks the coarse guard hairs found in most other breeds. Their large, bat-like ears, high cheekbones, and oval eyes give them a unique, almost elfin expression.

Common Cornish Rex Cat Health Issues
While generally healthy, Cornish Rex cats can be predisposed to a few genetic conditions. Responsible breeders test for these issues to minimise risks, but owners should be aware of potential concerns:
- Hypertrophic Cardiomyopathy (HCM): A heart condition that can affect Cornish Rexes
- Patellar Luxation: A condition where the kneecap may slip out of place
- Sensitivity to Anaesthesia: Cornish Rex cats can have a heightened sensitivity to certain medications
- Temperature Sensitivity: Their fine coat provides little insulation, making them more susceptible to cold temperatures
Regular veterinary check-ups and a healthy lifestyle can help manage and prevent these issues.
Cornish Rex Compatibility with Families and Other Pets
Cornish Rexes make excellent family pets due to their friendly and affectionate nature. They get along well with children, other cats, and even cat-friendly dogs. Their high energy levels mean they thrive in an interactive household where they can receive plenty of playtime and attention.
- Good with children and other pets
- Playful and energetic, needing regular engagement
- Requires companionship and does not enjoy being left alone for long periods
Should Cornish Rex's Be Indoor Cats?
Cornish Rexes are best suited as indoor cats due to several factors. Their delicate coat provides little insulation against the cold, making them susceptible to hypothermia in cold weather. As indoor cats, they are protected from outdoor dangers such as traffic, predators, and infectious diseases. By keeping them indoors, owners can ensure their safety and monitor their health more closely. For cats that enjoy the outdoors, supervised access to a secure garden or a catio can provide a safe and enriching experience.

Essential Grooming Tips for Cornish Rex Cats
One of the biggest advantages of owning a Cornish Rex is their low-maintenance grooming routine. Unlike most cats, they lack guard hairs, so they shed less and require minimal brushing. However, their fine coat can accumulate natural skin oils, so occasional baths may be needed to keep their skin healthy.
- Brushing: Light brushing with a soft cloth or hand rubbing is usually sufficient
- Bathing: Occasional baths help remove excess oils from the skin
- Ear Cleaning: Their large ears can accumulate wax, so regular cleaning is recommended
- Nail Trimming: As with all cats, their claws should be trimmed regularly
- Sun Protection: Their fine coat offers little UV protection, so avoid excessive sun exposure
Proper Nutrition and Feeding for Cornish Rex
A balanced diet is crucial for Cornish Rexes to maintain their health and well-being. High-quality cat food, whether wet or dry, should be the foundation of their diet, providing essential nutrients and vitamins. Due to their high energy levels, Cornish Rexes may require more calories than some other breeds. Fresh water should always be available to ensure adequate hydration. Occasional treats can be given in moderation, but should not make up a significant portion of their diet. It’s also essential to choose cat food appropriate for their age and activity level, as kittens, adults, and seniors have different nutritional needs.
