I used to want to breed and show Persian cats. I bought one from a breeder at a show. She and I discussed the process and I decided not to breed them after being told that because of the size of their heads, the queens can have difficulty delivering kittens and also that new moms can be so stupid, they need to be taught to care for their young. I decided I didn't want to perpetuate a breed that had trouble having their young. I neutered my cat. A few years ago, I adopted another Persian from a breeder who was retiring her from her cattery. She was a "pig faced" Persian. Both cats had respiratory issues, especially the little female. They both had litter box problems as well. I had the male put to sleep a few years ago when he started ruining the rug and was also developing eye problems. Yesterday was a very sad one. Sara, the little female was getting old and her nasal discharge was getting worse. It was getting all over her fur and she was developing an odor. I spoke to our vet about having her put to sleep soon. Yesterday, she crawled up on my bed and I found her semi comitose. I sat with her until she passed away. I believe that the way she was bred affected her quality of life and led to her demise. I know the show folks are going for the really flat faced look and are breeding really extreme animals. This is harming them. If any of you folks out there are breeding Persians, I suggest going for the less extreme "doll faced" Persians. Besides looking sweeter, it's more humane.
