I know some like to pretend that some things don’t happen in their breed. Pet Adopter can have unrealistic expectations so to set the record straight: Devon Rex and Sphynx are prone to yeast called Malassezia. Devon Rex are even more so and it’s proven by a study. This happens even more on a time of stress. It makes them brown. Sphynx are among the breeds more prone to heart disease so they need to be tested. Devon Rex are more prone to asthma and allergies. With that being said, we are very careful and try our best to avoid these issues and you should be looking for a breeder who does too. But the Malassezia yeast is something that will happen in a time of stress on especially Devon Rex. Living things are not robots and are not cookie cutter. It’s just like I have allergies to some foods. Someone else might have other genetic ailments. Responsible breeders strive for perfection in all regards, and it is the goal, but is not attainable in living things and cats are messier with ailments than you think. 30% will test positive for mycoplasma. 1 in 7 have heart disease. 90% have had herpes virus. And on an on. I am trying to figure out how to post the study done by Dr Abitbol. It’s 150 pages and I translated it to English.
