Tubby has one too - one of those that "swings from side to side when the cat walks."

It really doesn't swing when he walks, just when he runs. And it is so funny to see him run with his tummy swinging.

He's really not a fat cat - not even really Tubby anymore since he's lost weight because of his kidney troubles, but he hasn't lost his little pouch at all. That's still there, just swingin' away.

Oh, and he's had it forever....probably started developing when he was about 1 1/2 or so.
