We have a cat called Cassie. She is nervous. She doesn't like other cats a whole lot, yet likes people and dogs. She bumps against the Labs on purpose and meows. She is a short haired gray tabby (always been kept inside). She is 4 years old. She has only ever weighed about 7.5 pounds but now she is down to 6 pounds. She eats and drinks, but I can feel the tops of her hip bones when I stroke her. She's been to a vet, tested negative for FELV, is spayed, with all other shots. She sleeps alot (but then so do most cats), likes to be petted, but is squirmy. She sometimes spits up undigested food after eating quickly. She is a very picky eater. Should we be concerned about the weight? She is the one I mentioned before that pulled her fur out on the backs of her hind legs (the weight thing and the fur thing started about the same time).
