If your hand is warmer than the mouse they will go for your hand - I use tongs so not to get tagged. After mine eat their 1st mouse they go back to there hide to realign their jaws and then its back to hunt mode for mouse #2. After the 2nd mouse they hide for almost 2 days to digest. I guess if they were to poke their heads out again I would probably offer a 3rd mouse, but that hasn't happened yet. My baby gets 2 small mice and my 1 yr old gets 2 large mice. Seems to work for now.I'd try to offer a second one at the next feeding... Good luck! And yes its normal.
