I am not sure what brought on the question as to whether or not people should own Ferrets, there are people that own Hedgehogs, Chincilla's, Rats, Mice, Skunks, Guinea Pigs, Rabbits, etc. Geez, you even have people out there that have wild cats & wolves as pets..What harm can a ferret do? For me, I don't see any reason why someone can not own a pet of their choice as long as they know how to handle and maintain it.
