Okay, so this won't be entirely about a fat cat, but fat animals in general. If you think your kitty with the jiggle draggy belly is overweight, you may be right, but you are not necessarily the owner who your vet is the most concerned about. Lately I have seen several cats that don't have a belly, their entire body is not just thick, but like a large deflated football, or like a bag of flour. These cats are fat.
Today we got a dog, I forget the breed, but it's one of those short long dogs with the stubby legs that already looks malformed without any extra help. This dog was fed table scraps and junk like that. The man who brought it in described the dog as belonging in a circus sideshow. He was completly right. This dog didn't just look overweight or fat, it looked like a bloated balloon. he was a cartoonists dream, the real life depiction of these crazy looking dogs.
