Well, it's been a while since I've posted on this thread. I thought the shot was working for Taz, but when we went back to the vet this past Tuesday he had actually lost MORE weight. He was 12.7 lbs. So the doctor wanted to do an ultra-sound, which would have been big bucks. But instead we decided to give him a stronger cortisone shot and she told me to feed him "kitty junk food". Anything that he will eat, give it to him. She did list three brands to not buy. I think it was Crave, Friskies and Whiskas. Anyway, I got him some dry Cat Chow and some wet food I'd never heard of before. He has been cleaning his bowl at each meal!! Woo Hoo!! So at this moment Taz is the KING of the house. He will get whatever he wants.
He is also not bugging me endlessly anymore. It's such a relief. I will weigh him again in two weeks and see if he's gained any poundage.

Thank you for listening to me express my relief.
