I've tried, Nancy, but Fluffy has inflammatory bowel disease, and he gets so stressed out that he gets diarrhea
when I try to shut him out. That is not pretty on a white three-legged cat, and he makes a mess.
He's almost 16, and I can't change him now. I've tried earplugs, I've asked the vet for something to calm him down. The med calmed him down, but made his stomach and bowels very upset. Oh, and at 16 pounds, he hangs over the sides of my lap, lol.
