When you feed nubi how much do you "annoy" him with the mouse? To get Kuddles to feed i have to gently tap him on the side of the body/neck and up around the head for up to 5 mins before he will strike at the food, which is down from 15-20 mins when i fist got him, and i have found that at the moment he like to be fed out of his enclosure while hanging from something, and he prefers rats over mice. It sucks when you have to waste mice/rats coz they wont eat, maybe let him go another 4 days or so before offering again, it wont hurt him, and he might be a bit hungrier by then. I have read posts/threads where peoples hatchies havnt eaten for months and they are still fine.
