I don't understand the gerbils, a lot are born in captivity and they've been kept as pets for a long time. I understand the wild animal bans and bans on threatened or dangerous species. I wonder if they have any regulations on aquarium fish. Just about anybody can go out and buy an endangered species of aquarium fish. Some species are almost completely wiped out in the wild. Anyway, my point, who's going to find out if you have a gerbil? Unless you have a friend you get in a fight with and they tell on you.
