You're right.. there's a 2"x2" gap under the cabinet that I never noticed.. I hope it doesn't like lead straight into the floor or something.. or we will never get him out. I feel AWFUL. What's the best way to lead him out (if there is one??).. A f/t mouse in the middle of the floor in the dark.. could the smell work? It's been about two weeks since he's last eaten, and he shed in that time.
Could it have gotten into the crawl space underneath the house? It's dark and alot cooler under there. Couldn't you put a fan facing the enclosure to cool him down? How hot is it in your house?
