Hello! I have a beautiful, wonderful, perfect cat, Muzak. He will be 22 in January, and has recently gone almost completely blind; I think he can see a little light/dark. He hasn't played or run around in a year; he has mild arthritis but the vet says he's not in pain, just aches. He has a pressure-activated cat heating pad that he's glued to; since he went blind he never leaves it except for food and the litter box. I don't blame him, I'd do the same thing. But is there anything I can do to entertain him, or give him a reason to walk around some? He does come on my lap a little still, but when I have to get up, he's pretty upset, so his visits are getting much fewer. He also lost his sense of smell a year ago, so he doesn't respond to catnip, or even chicken. Any suggestions would be very welcome.
