Ok, most of you know what my little gerbil looks like. Well, he's not that little anymore. With all the recent events we (my family) havent been home enough to let little bit get some exercise out of his cage. Now he feels like im holding a real fast alive apple. God he's heavy! Does anyone know of a way to get gerbils to lose weight because his little run about ball is colored red so he wont run in it.
