Hi, my 3 year old kitty died last week from congestive heart failure due to HCM. I'm utterly heartbroken. We purchased him a breeder in Southern California who never told us how common the disease is or that we should get him scanned as a preventative measure. Do you know how common HCM is in the breed and can they live a normal life if they test positive? Do all breeders have some cats that will die from HCM before the age of five? I loved my Sphynx more than anything but I’m having serious doubts about getting another one because I never want to go through this again. Thanks for your help and understanding. --Dee
