I'm not sure what happens with petstore kittens, but have heard of kitten mills. Most of us by now have heard of puppy mills, but most haven't heard of kitten mills. The queens go through about the same thing dogs do, crammed into cages pregnant constantly on the cheapest quality food until they can't breed anymore. Then they are disposed of in whichever way the breeders see fit. I sure hope people continue to be educated about petstore animals and choose a shelter pet instead. Supply and demand are what keep these pup/kitten millers in business. *SIGH*
