My new Sphynx, Lily, is starving all the time. She will eat anythig, including my food (which she does not get.) She most definitely is being fed enough. Maybe even a little more then she should be getting. She is very much on the skinny side. I just got her from a rescue, so don't know anything about her history, other then she was just recently spayed, and had a dental & 4 teeth pulled. She was completely vet checked before she came to me. I got her from a very reputable rescue. She is, they guess about 5yrs old. She is an absolute sweetheart, but walks around screaming at me all day for food. And she will definitely push Sammie out of the way for food, so I have been feeding them in seperate rooms. I feed twice a day - do not free feed.Any clues?
