the reason most likely it's not feeding is the size of the tub you have him in. (too big) I would try what steveboos posted with the hide. he's active in his tub cause he's stressed by the size of it. if you placed the rodent a little in the throat and he's getting a feeding response for having something in the mouth and takes it the rest of the way by himself that's good. lower the stress for him (with a hide) and he should go by himself soon. you might want to junk up the tub so it doesn't feel so big, and once he eats, start taking things out slowly. if he doesn't feed by himself in 2 weeks, PM me and I'll give you something else to try that usually works well, and I'll explain why it works. good luck, don
