what do you mean eat your finger ? Did you offer it up to him? or did he just strike for the mouse and get your finger? or did you feed him the other night, and tonight he struck at you as if he was hungry (no rat/mouse scent)?
well i was holding him, not really paying attention and he bit down on my finger like he was gonna eat it. hes id say about a foot and a half and at his thickest point hes a little over the size of a quarter.
