I have a deaf ferret named Skippy.  Whenever he is naughty (which is
often) I scruff him and tell him no, just like I do the other ferrets,
but I have to emphasize the wagging of the finger in front of his face
and my upset grimace.  The problem is, he just closes his eyes and goes
"la-la-la".  What else can I do to get the message through to him?
