Health problems linked to the Cornish Rex

Conditions and what they can cost
ConditionWhat it isRelated costs
Progressive retinal atrophy (PRA)Named by: PetMD vet-reviewed guide [1]The cells at the back of the eye slowly wear out, starting with night vision. It isn't painful, but it can lead to blindness. [2]Cat vet visit (owner bills): $190–$525 [3]
Hypertrophic cardiomyopathy (HCM)Named by: PetMD vet-reviewed guide [1]The heart muscle thickens and stiffens. It is the most common heart disease in cats and can cause heart failure or blood clots. [4]Cat heart ultrasound (owner bills): $90–$400 [5]

Costs are national figures from our sourced cost guides, not breed-specific prices. Being on this list doesn't mean a pet will get the condition.

PetMD's vet-reviewed guide to the Cornish Rex lists these conditions to know about: Progressive Retinal Atrophy (PRA), Hypertrophic Cardiomyopathy. [1]

Health screening

The UC Davis Veterinary Genetics Laboratory lists 3 DNA health tests for the Cornish Rex, including Progressive Retinal Atrophy (PRA rdAc) (Abyssinian); Dilute; AB Blood Group in Domestic Cat Breeds. [6] One health test costs $47 there. [7]

What to budget

Breed-specific cat bills aren't published, but a routine vet visit for any cat typically runs $190–$525. [3]

Lifetime cost, roughly. Our yearly estimate for an adult Cornish Rex at US-average prices, before insurance, is $800–$1,300. Multiply that by a life expectancy of 11–15 years and you get roughly $8,800–$19,900 over a lifetime, before inflation and before any major illness. The low end is the ASPCA's yearly cost of care; the high end adds one typical vet bill a year. [3][8] It's simple math on sourced figures, not a quote.

Insurance and savings

The average accident and illness policy cost $435 a year for a cat in the US in 2025. [9] Timing matters more than the price. A condition that shows up before you enroll is usually treated as pre-existing and isn't covered. [10]

Prefer saving instead? Putting money aside each month works too; see insurance vs a savings fund.
