the only flaw I can see in this statement, most animals can be trained, if the owner/handler knows what they are doing, now Im not saying the poster dos'ent know what he's doing, but ALL FERRET KITTS BITE, its how we keep them, handle them etc, that teach them not to bite us, so giving the advice of, if its keeps doing it, knock them on the head and get some more, because as you say, thats how stockmen get good stock, is bo****ks, as the next lot of kitts they get WILL ALSO BITE, unless taught/handled correctly
