What is HCM and why is it important to make sure the cattery you are buying cats from is tested Negative?
Feline hypertrophic cardiomyopathy (HCM) is a disease of the heart muscle in which the walls thicken and the heart enlarges. HCM affects the left ventricle and its functional ability to pump blood into the aorta. Maine coons are particularly prone to this genetic disease. In all classes, the heart disease usually results in clinical signs of heart failure.
