Any information on this would be greatly appreciated.
I have seen Persians with underrbites. I think they are adorable. But I do believe it is hereditary... However not all her kittens will have the same thing. Some will be perfectly normal. And I got my Persians and my Birman from Breeders who did show cats but their main thing was breeding loving and wonderful furbabies. They didn't really care too much about the show circuit and producing perfect show kittens. It was nice if it happened but they also did not cage their kitties and they were very hands on with every litter. I also do not think they were BYB's... BYB's are people that do not care and are only trying to make a quick buck off their animals. They don't take their animals to the vet. Good breeders care very much about their animals and do all they can for them. You clearly do, as well. She is beautiful and happy. That is what matters!!
Yes, I know. I wasn't the one that brought it back up.. It was someone else and their post has been deleted. I reread the entire post and noticed that but it was too late. I couldn't delete my post. I am sorry. It is not me doing this, I promise!!
