I'm fine feeding mice, I would just rather not use rats. Anything else is fine. At least for now. Eventually I might be able to feed rats, but my girls only passed away a few years ago.any snake that will feed on mice can eat them, but mice are higher in fat than rats, so i like to use rats to beef up my boas, if your looking for a snake that doesnt eat rate or mice, hognoses will eat toads readily, most people switch them to pinkies, but im sure you could talk to a breeder to get a hatchling that hasnt been switched, and they are rather small snakes
