What a joke! These commision board members who are even considering this are obviously mentally ill... They must be closet PETA members...
Why dont you just make animal abuse illegal? Oh wait it already is!
Drugs are illegal in San Francisco, doesnt seem to stop anyone from doing them though... You make pet sales illegal and you will suddenly make basement breeding very profitable, black market hamsters will suddenly flood the city, and I can guarantee their living conditions will be even more atrocious than any commercial breeder!
