Silent heart disease hides until it’s too late.

It’s one of the most devastating experiences a cat owner can face—your cat seemed healthy, playful, and then suddenly collapsed without warning. Many of these unexplained deaths trace back to undiagnosed heart disease, particularly hypertrophic cardiomyopathy (HCM), the most common cardiac condition in cats. The disease thickens the heart muscle until it can no longer pump blood effectively. Because symptoms often stay hidden until the final moments, most owners never realize what’s brewing inside. Understanding the subtle signs and knowing how to act early could mean everything.
