Like what, birds and rabbits and such? Craigslist from local breeders.
We always push for people to buy reptiles from reputable breeders. Why shouldn't we advise the same for other species of animals? Most people that buy those kind of animals usually just purchase on a whim because they see it and think, "aweee, that's so cute!" Then end up getting rid of it once they get bored with it or realize birds are loud or some other various reason. Sounds like the kind of thing this bill is trying to prevent since they won't just be buying random animals on a whim just because they saw it in a pet store... I have no problem with that personally, since those that still want to get an animal will still be able to do so, and it will most likely be healthier and better quality. I'm not a big fan of pet stores for the most part.
