Thread: Heart Murmurs in Maine Coons

Hypertrophic Cardiomyopathy is a recognised defect in MCs. 34% of the UK Maine Coon population is said to have it. Sorry don't know figures for anywhere else.

A murmur can be a sign of HCM although not necessarily so but I'd make sure that the baby is thoroughly and specifically checked at least annually.

I have HCM, as far as I know I am still alive and kicking.
