Btw, breeders dont know much more than anyone else when its related to animals. Of course, there are exceptions and there must be some very good ones.
My girlfriend is a vet and she gave a conference to bird breeder a few months ago and she was surprised by their ignorance. They often use their own way to treat an animal rather than going to the vet. And their own way often look more like alchemy than medicine... But then again, maybe it was just a small group of breeders who were there and its not representative of the general market...
Anyways, if you want a pet, you can always go to the vet clinic and ask if they have a pet to give. They generally wont charge you anything for it and they will give you a detailed account of his health state. So its even better than going at the pound.
