The short answer
The Cornish Rex is generally a healthy, active breed that often lives into its mid-teens. The conditions worth knowing are hypertrophic cardiomyopathy (HCM), the most common feline heart disease, which is reported in the breed and can be serious but is often manageable when caught early; patellar luxation, a kneecap issue that ranges from mild to surgical; and the skin, ear and dental care that a very fine coat demands. Mention the breed to your vet before any anaesthetic, since a fine-coated, lean cat needs to be kept warm and may need a tailored approach. Adopt from a health-testing source, have your own vet examine any cat, keep up regular check-ups, and consider pet insurance while the cat is young.
Hypertrophic cardiomyopathy (HCM)
HCM is the most common heart disease in cats, in which the heart muscle thickens and the heart pumps less efficiently, and it is reported across many breeds, the Cornish Rex among them. It can stay silent for a long time and then appear as fast or laboured breathing, lethargy, a drop in appetite, or, in serious cases, sudden weakness in the back legs or collapse, and it can be genuinely dangerous. There is no cure, but a cat diagnosed early can often be managed with medication and monitoring and enjoy a good quality of life. Your vet can listen for a heart murmur or an abnormal rhythm at routine check-ups, and a veterinary cardiologist can confirm it with an ultrasound of the heart, an echocardiogram, which is the definitive test. This is the single strongest reason to keep up with regular vet visits and to adopt from a source whose cats are screened.
Patellar luxation and joints
Patellar luxation, where the kneecap slips out of its normal groove, is reported in the Cornish Rex. It ranges widely, from a minor, intermittent skip in the step that never troubles the cat, to a more significant problem that causes lameness and may need surgery to correct. Signs to watch for are an occasional hop or a held-up back leg, or reluctance to jump. If you notice anything like that, your vet can examine the knee and advise whether it needs treatment or simply monitoring. Keeping the cat lean protects the joints, which is one more reason not to let an active breed become overweight.
Skin, ears and coat
The Cornish Rex's very fine, sparse coat does not spread the skin's natural oils the way a full coat does, so the skin can become a little oily and, occasionally, irritated, and the large ears collect waxy debris. Practical care is simple: an occasional gentle bath with a mild cat shampoo (ask your vet how often), regular gentle ear cleaning with a vet-recommended product, and a look at any red, sore or smelly skin or ear, which may be an infection needing treatment. Because the coat offers little protection, be mindful of sunburn on exposed skin through a hot window, which an indoor lifestyle makes easy to avoid. Our companion guide to the breed's coat and warmth covers day-to-day coat care in more detail.
Dental health
Dental disease is common in all cats and worth staying ahead of. Bad breath, drooling, difficulty eating or pawing at the mouth are signs to have checked. A dental routine at home, where the cat tolerates it, plus veterinary dental checks and cleaning as needed, keeps problems from building up. The RSPCA Knowledgebase has good general guidance on cat dental care, and your vet will advise what suits your cat.
Anaesthesia and general care
Mention the breed to your vet before any procedure that needs an anaesthetic. Two practical points come up with fine-coated, lean cats: they lose body heat quickly under anaesthesia and during recovery, so a good vet keeps them warm throughout, and a low-body-fat cat may need a tailored drug approach. This is routine for an experienced vet, not cause for alarm. Beyond that, the everyday essentials are the same as for any cat and matter just as much here: year-round parasite prevention (paralysis ticks are a real risk across South East Queensland and easy to feel on a fine coat), keeping the cat lean and active, and regular check-ups so anything is caught early.

Is the Cornish Rex a healthy breed?
The Cornish Rex is generally a healthy, active breed that often lives well into its teens, and many individuals never develop a serious inherited problem. Like every pedigree cat, though, it has a few conditions that appear more often than in the general cat population, and knowing about them helps you choose a responsible source, ask the right questions and catch problems early. The most important are hypertrophic cardiomyopathy (a heart-muscle disease), patellar luxation (a kneecap issue), and the skin and dental care that comes with a very fine coat. None of this should put you off the breed; it simply means going in informed and keeping up with vet checks.
What is HCM and why does it matter in the Cornish Rex?
Hypertrophic cardiomyopathy, or HCM, is the most common heart disease in cats, in which the heart muscle thickens and the heart pumps less efficiently, and it is reported across many breeds including the Cornish Rex. It can be silent for a long time, then show up as fast or laboured breathing, lethargy, reduced appetite, or in serious cases sudden hind-leg weakness or collapse, and it can be seriously dangerous. There is no cure, but a cat diagnosed early can often be managed with medication and monitoring for a good quality of life. A vet can listen for a murmur or gallop at check-ups, and a veterinary cardiologist can confirm it with an ultrasound of the heart (echocardiogram), which is the definitive test.
What other conditions should I know about?
A few worth understanding. Patellar luxation, where the kneecap slips out of its groove, is reported in the breed and ranges from a minor intermittent skip in the step to a problem that needs surgery. Because the coat is so fine and sparse, the skin can become oily or occasionally irritated and the ears collect wax, so skin and ear care matter more than in most cats. Dental disease is common in all cats and worth staying ahead of with home care and vet checks. As with any pedigree, buy only from a breeder who health-tests their cats, and have any cat you adopt examined by your own vet. Your vet is the right person to assess an individual cat, since the presence and severity of these conditions varies widely.
Do Cornish Rex have any special anaesthesia needs?
It is worth mentioning the breed to your vet before any procedure that needs an anaesthetic. Two practical points come up with rex cats. First, the very fine coat gives little insulation, so a Cornish Rex can lose body heat quickly under anaesthesia and during recovery, and a good vet will keep the cat warm throughout, which is standard care. Second, lean, low-body-fat cats can respond to some anaesthetic drugs differently, so your vet may adjust their approach. This is routine for an experienced vet, not a reason for alarm; simply make sure your vet knows you have a Cornish Rex so they can plan appropriately.
Should I get pet insurance for a Cornish Rex?
It is well worth considering. A condition like HCM or a knee that needs surgery can mean ongoing medication, specialist cardiology or an operation, and those costs add up, so insurance taken out while a cat is young and healthy can make a real difference to the care you are able to give. Read any policy carefully, since pre-existing and some hereditary conditions may be excluded, and compare a few options. If you would rather self-insure, set aside a dedicated fund instead. Either way, know where your nearest after-hours emergency vet is before you need it: on the Gold Coast the Animal Emergency Service at Carrara (104 Eastlake St, Carrara) provides after-hours and weekend emergency care.
