i know this is an older thread, but i wanted to add to it. I had to help my little Perry. She's a tiny 100 grams, and I wasn't sure she could eat a full mouse. But, for the sake of growth I gave her a fuzzy and left her. I come back to her bottom jaw hooked on her back. She was bleeding a bit and really writhing around trying to get unstuck. She had the food by its shoulder, so the head was bending backwards, making it REALLY hard to get down, plus the lips being stuck to her back thing. So, that one time I had to hold her down and unhook her from herself. Idk why you'd take the mouse away though.
