British Shorthair and American Shorthair are relatively common purebred cats, and everyone thinks they are very healthy. In fact, British and American shorthair cats also have genetic diseases (most purebred cats have some diseases).

The genetic diseases of British and American shorthair cats cannot be underestimated.

Myocardial hypertrophy is the most common myocardial disease in the UK and the United States. There are no obvious symptoms in the early stages of this disease. Once the symptoms are obvious, it is already life-threatening. Owners can pay more attention to the health of cats at an age when genetic diseases are more likely to occur. If conditions permit, they can take them to the pet hospital for regular physical examinations.

The genetic disease of British and American Shorthair usually occurs between the ages of 1 and 3, so cat owners should feed their cats scientifically at this stage to reduce the chance of accidents.
