Is it worth it to genetic test your cat before breeding?
YES!!!!!!! ABSOLUTELY without a doubt it is worth ever single penny to genetic test any animal BEFORE you breed them. I love my cats and want to provide healthy, happy kittens. All of our maine coons are genetic tested using Optimal Selection, and also have echocardiograms to check their hearts for early signs of HCM. Maine Coons are generally a healthy, hearty breed of cat but like all animals they are only as healthy as their parents are. 
Optimal Selection tests are a swab-at-home kit that screens for more than 25 genetic mutations causing inherited feline diseases and tests for traits such as coat color and length and morphology. Unfortunately because other dishonest breeders have been known to falsify records, I will not be posting the results of their genetic testing or pedigrees online. If you are interested in adopting a kitten from us, I am happy to share the results of their echocardiograms and Optimal Selection results. All of our breeding cats are  negative for HCM,PKD, and SMA.
