hiya i dont think pet shops should be banned from selling animals but i do think they should be far more regulated and they should not be allowed to sell cages which are too small for the animal. i think there should be a law on cage sizes so it is against the law to keep animals confined with not enough room.
i also think people shoud THINK before buying that cute bunny in the window and remember its a living animal that has needs. a planned pet is fine but some people buy pets on the spur of the moment because its cute and have no idea how to care for them or how long they are going to live!
