My pregnant Silver Girl-She’s huge❤️🐯It is important that you ask the breeder if they HCM test their breeding cats when buying a kitten!!! Hypocardiomyopathy (HCM) is a deadly disease that runs in exotic breeds. If the breeder does not test and can’t provide documentation that they do so, move on to a reputable breeder that does test for HCM. This test is done yearly.
