A concise guide to typical adult needs and characteristics.
Lifespan values identify ranges, study medians and open-ended estimates explicitly. Ratings appear only for comparable care or activity scales. Individual animals still vary with age, health, breeding, environment and previous care.
Profile description
The Cornish Rex is a slender, athletic cat with a very short wavy coat and large ears. It is playful, affectionate, active and often seeks warmth and close contact. Within the Cornish Rex, thoughtful breeding may produce recognisable tendencies in body type, coat, activity and social behaviour, while individuals still vary. Early, positive handling and a stable kitten environment help a Cornish Rex develop confidence and adaptability for adult life.
Its unusual coat is produced by a specific hair-shaft or follicle trait. Texture can vary across the body and between kittens, and fragile or sparse areas should not be interpreted as automatically unhealthy when the skin itself is comfortable and normal. Movement and novelty commonly draw the Cornish Rex into household activity. Without enough climbing, chasing and thinking opportunities, the inventive Cornish Rex may redirect its energy into nuisance behaviour.
Strong social attachment can make the Cornish Rex a frequent companion during ordinary household activities. Prolonged isolation can contribute to calling, over-grooming or overeating in the Cornish Rex, making companionship and enrichment important. A suitable Cornish Rex home provides safe indoor living or a secure enclosure, scratching surfaces, several resting places, clean litter trays and retreat from unwanted attention. Social interest in the Cornish Rex is best supported by predictable attention and gentle boundaries rather than constant handling or forced interaction. A well-matched Cornish Rex should have opportunities to express normal feline behaviour while retaining control over when to approach, play, rest or withdraw.
A responsible source for a Cornish Rex should provide health records, explain known family risks and match the individual cat to the owner's experience and lifestyle.

Care requirements
Protect from cold and excessive sun, clean the ears and skin as needed and avoid harsh brushing. Provide daily play, weight monitoring and breed-relevant health screening. Plan several active Cornish Rex play sessions daily using wand toys, retrieving, chase games and food puzzles. Tall stable climbing structures and rotating enrichment help the Cornish Rex avoid boredom and frustrated behaviour. Reward-based Cornish Rex training can teach recall, carrier entry, nail handling and calm behaviour around meals. Groom gently so the characteristic coat is not broken or pulled straight.
Use fingers or a wide-toothed comb where appropriate, check sparse areas for irritation and clean the ears regularly because wax can accumulate in some rex and hairless-related lines. Feed the Cornish Rex a complete and balanced feline diet appropriate to age, reproductive status and health. Measure the Cornish Rex's portions, record weight and body condition, and adjust calories before excess weight becomes established. Provide the Cornish Rex fresh water in several locations; wide bowls, fountains and moisture-rich food may encourage drinking.
The Cornish Rex's dental care should include tooth brushing when tolerated, regular oral examination and investigation of bad breath, drooling or changed chewing. For the Cornish Rex, trim nails as needed, check the ears for discharge or odour and monitor litter trays for altered urine, stool or straining. Before breeding, discuss heart examination and, where appropriate, echocardiographic or breed-specific HCM screening, PKD DNA testing or kidney ultrasound in relevant breeding lines, breed-appropriate retinal examination or validated DNA testing where indicated.
Seek veterinary care promptly if a Cornish Rex develops breathing difficulty, repeated vomiting, inability to urinate, sudden weakness, collapse, seizures, severe eye pain or refuses food. Because a Cornish Rex may conceal illness, subtle changes in appetite, grooming, jumping, social behaviour or litter use can be important early signs.
