Every cat is an individual, and mixed-breed cats can have health risks too. Still, some purebred cats are more prone to certain conditions. Knowing the risks helps you screen early and act sooner.
Maine Coon
Hypertrophic cardiomyopathy (HCM), a thickening of the heart muscle, and hip dysplasia occur in the breed. Ask your vet about heart screening.
Ragdoll and British Shorthair
Both are associated with HCM. Regular exams and, where recommended, cardiac screening can help catch it early.
Persian and other flat-faced cats
Polycystic kidney disease, eye problems, tear staining and breathing difficulties are more common. Keep faces clean and watch for squinting or noisy breathing.
Siamese and Oriental breeds
Some are prone to asthma, dental disease and certain eye conditions.
Bengal and Abyssinian
Inherited eye conditions such as progressive retinal atrophy and certain inherited blood disorders have been reported. Reputable breeders screen for them.
Sphynx
Skin care matters, since they lack a protective coat and can get greasy skin or sunburn. HCM also occurs.
What every cat owner can do
- Schedule regular exams, with more frequent checks for seniors
- Ask whether genetic or heart screening makes sense for your breed
- Watch for changes in appetite, thirst, weight, litter box habits and energy
- Keep your cat lean and active
- Keep dental care up
When to call a vet
Rapid breathing, open-mouth breathing, sudden weakness or hind-leg paralysis, which may signal a blood clot, are emergencies. Need an in-person clinic? Find a vet near me.
