I forgot to add this to my previous comment. There must be some money to be made by kitty mills, but my guess is that it's not much. It's usually the pet shop that makes the money. I'm in Japan, so the situation might be different from that in the States, but my local pet shop (part of a big chain; the animals look healthy and well-treated) charges over $2000 per purebred kitten (with pedigree). Your average household breeder, in Japan, will charge anywhere from $600 to $1000 (I'm talking about Maine Coons here), and if it's a good breeder, the kittens will be of much better quality than what you can get from a pet shop. Less expensive cats are not necessarily of a lower quality than more expensive cats, but human psychology is strange--some people are convinced that the more expensive a cat is, the better it must be. Cats are not cars.
