Also super-aggressive huge beasts, in the case of lions and tigers.

My grandmother had a yellow-and-white cat that would get things like cat toys and treat bags in it's mouth and not let go - occasionally after successfully pulling the item away from the grip of human hands he would then shake and worry the item like a terrier with a rat.

Same thing for human males, too. *sigh*

Get away with it? I think you mean, "if they had new servants lined up to replace us".
