Ferrets

I'm looking for information about wild ferrets, as well as stoats and weasels.

Do all three species live in the same area?

Is there anything about them you think would make a good hero? (For example, do they take good care of their young?)

A "wild ferret" would be a polecat, their closest decendant. In fact, all a ferret is, is a polecate who has been bread out of its preditory instincts over generations upon generations.

Thanks.
