I feel stupid asking this, since I kind of already know the answer, but I guess I need conformation. I have been debating with myself, whether to feed 2 mice or one rat. Piston loves mice, but I like how rats, encourages him to grow. I have no intentions of breeding him/her I just want him to be as big as possible. He also got a heck of a lot more girth, since I start feeding rats. No, I do not power feed. He takes rats just fine, but I'm having problems deciding what size to go for? He is about 26" long, and his girth is about the size of a golf ball. Assuming you have normal size hands, the girth is about the same size as when you touch the tip of your thumb, with the tip of your "pointing" finger. I hope that gives you guys and idea. I find myself, in the pet store I go to, always asking for the biggest fuzzy rat they have, and always seems too small. This is the main reason I sometimes feed two mice, instead of rats. Even the biggest fuzzy rats I fed, leave no lump in his body.

Anybody out there with a similar size bp? If so, what do you feed?
