Ferrets are for life...
Ferrets in Australia are being dumped in the wild by stupid owners and ferret groups aren't happy. They say breeders are not giving ferret owners enough information to make an informed choice about owning the animals, and because of that the ferrets are suffering.
Specifically, the tendancy to nip and smell is being downplayed, as well as the amount of care ferrets need. Many bad breeders classify them as "easy to care for cage animals".
Ferrets in Australia have already been outlawed in Queensland, and many Oz ferret owners worry such dumps may make them illegal where THEY live too.
