I have a deaf boy to and this may sound very weird but it works let me tell you. First I will explain how a mother ferret disciplines her babys, she scruffs them and drags them across the floor. So I started doing this I'd scuff him make th3e disapointed face and when he'd turn away I'd lay him on the floor while still scruffing him and drag him abou a foot or so if he kept up he got drug about two feet. that certianly worked with my guy, now if that dosn't work I had to actually scruff him in my mouth and drag him, I only did that twice and he never was naughty in that manner again. Hope this helps, Mya Falkkor & Lukas [Posted in FML issue 4314]
