I have a female I adopted from the streets. When we got her last November she was about 7lbs, since then she has kept gaining weight to over 17lbs and still climbing, so we cut her canned food and she is eating dry food and drinking lots of water. But now I'm concerned that even though she has lost 2lbs in the past 2 weeks she is starting to get bald spots on her that we thought at first she was picking off, but now she has one on her head. She is declawed so its not that. Could these be related at all?
