Hypertrophic cardiomyopathy (HCM) is a disease of the heart muscle. The exact way the disease occurs in cats is unknown, but the result is that the heart muscle becomes extremely thickened with normal and abnormal cells. The thickened muscle can’t relax and contract normally, so HCM decreases the amount of blood that the heart can…
