The Mustelidae are a family of carnivorous mammals, including weasels, badgers, otters, ferrets, martens, minks, and wolverines, among others.

Look at that list - they all be killers - even a happy fun loving ferret will go beast mode on rodents if they see one.

I really enjoyed this video on what a determined mink and a dog can do to an infestation of rats in an old barn.

40 or so years ago I went to visit my girl friend and her room mate. They were hiding in the closet because their pet ferret was having a bad day and had bitten both of them. He seemed perfectly friendly to me and was begging for food as usual.

Weasels ripped my flesh.
