I have two very slim cats, and I'm pretty sure they stay that way because the baby eats their food as well as his own...the third cat is a little pudge! He runs around all day long, so I have no idea how he keeps the weight on (he's perfectly healthy according to his vet), but god love him he looks like Jabba the Hut from above!

Sure you are, buddy, sure you are
