Thanks, Lynnestankard.

Tubby is in the beginning stages of kidney failure and used to throw up a lot, and I think he wasn't eating as much either, so he has lost a couple of pounds in the last few years. Now we've got it under control and he is eating more, but he doesn't seem to gain the weight back. Someone who was seeing him for the first time said "He's an older cat isn't he?" When I said yes, she said she could tell because he's got the body of an older cat (not as muscular as a younger cat).

So I guess everything sags for the kitty kats as they get older, just like it does on us.
