I have been seeing a lot of posts all over the internet about Persians being unhealthy because of being bred to show standard. This statement is in the least misleading and worst, just plain WRONG. If a Persian comes from a caring, knowledgeable breeder the cat should have no problems breathing. A good breeder will breed for large nares (nostrils) among other qualities. Most of the problems come from back yard breeders or people who don't have the knowledge to breed responsibly. PLEASE, when you buy any pedigree pet (cat or dog) DO YOUR RESEACH!! I will get off of my soapbox now and go clean litter boxes.
