Nothing works for my cat. He's on every horizontal surface in my house. He has his own multiple level tree. His latest is to pull the rubber ring AND metal cap off the disposal and play with them on the floor. I've tried everything suggested but nothing works. I say NO, firmly, he bites me and draws blood. I'm 83, love him like a child but I'm at my wits end. He's nine months and eleven pounds. I do not like cats on my counters. I'm a clean freak. HELP!!!
