I have a normal ball I think 4 months and he had a little larger mouse than he is used to on his last feeding. I haven't seen him in a few days other than spotting him in his hide. I was told feed him in a brown paper bag. he did fine excellent. but I would like him eating in his cage and it kind of works for me.As I am just now thinking about feeding, in his tank and see if he will take it.
