British Shorthair Health Problems
British Shorthairs are generally hardy cats, but their popularity has brought some genetic health concerns to the forefront. They're prone to a serious heart condition and obesity. Understanding these risks helps you keep your British Shorthair healthy.
British Shorthair Lifespan: What to Expect

Genetic Factors
The breed's round, stocky build can lead to weight issues. HCM is the primary genetic concern, and responsible breeders screen for it.
Common Health Issues in British Shorthairs
Hypertrophic Cardiomyopathy (HCM)
Thickening of the heart muscle. The most common heart disease in cats and particularly prevalent in British Shorthairs.

Obesity

Hemophilia B
A bleeding disorder found in some British Shorthair lines. Causes excessive bleeding from injuries or surgery.
Symptoms to watch for:

Warning Signs to Watch For
