That's so unfair! Poor guy. Don't let it deter you from continuing to work on your own weight, though. Thirty pounds is such a great start that it would be a shame to stop now. You have to regain some mobility. Phil was your whole family, so I know how hard it will be for you to cope with everything on your own.
Do you still have your sweet lilac point Siamese? I lost both of mine years ago. I really miss them. It's such a special breed -- the puppy dog of the cat world. The cats I have now don't take walks with me the way Snowball and Vanilla did. They follow me for a little while and then rush back home for some food and a nap.
