I have a fuzzy who has insulinoma, and doesn't seem to have alot of energy. I have him on a high-protien diet, which gives him enough energy to want to come out of the cage, but he doesn't play with the other 3. He's not interested in toys or playing at all. He likes to come out of the cage and find another place to curl up in and sleep. He's pretty chubby now, and it's all mush, not much muscle. Any ideas? [Posted in FML issue 2458]
