Genetic Testing for HCM-Not Always Necessary

This is general information and not really helpful for those with HCM cats. But apply it to your other cats; tell your friends, etc.

I believe your cat doesn't need a DNA test to see if they might get HCM. They could still possibly get it even though they do not have the gene. But it is a good starting point for breeders since many top breeds of cats are prone to HCM.

Also-testing and being positive with a gene tells you nothing-you still must wait to see IF the disease will occur in your cat and to what extent. For that you need to see a cardiologist at least annually and then wait for it to appear.

I recommend that all cats see a cardiologist when a kitten, or when you first get one home; then again when they are four, then age six or so, and then annually once they are ten because the heart ages and issues can arise. Also see the cardiologist if your cat has a detectable murmur, or if they need surgery, or they need dental cleaning/surgery, if they need anesthesia for anything such as an MRI. If you do not, the anesthesia will likely cause CHF-the first sudden sign of HCM that typically hits a cat. (It's likely HCM or CHF signs were appearing at home but owners missed them.)
