I have an odd question. Isis (3y/o, F calico) waddles. She is no longer really overweight and the vet said she only had about 1lb more to lose to be at an ideal weight. If you watch her walk from behind though...she waddles. It kinda looks like she's got something up her bum...like if you where walking around trying to hold a coin between your butt cheeks. This isn't something new and she has walked like this as long as I've known her. Just looks funny/awkward. Any insight? Other than this she is a very graceful cat, jumping and landing with barely a sound. I wish Loki could learn to jump down from things a bit more gracefully
