Seams every fall, at least one mouse is silly enough to try and move in. The boys play with it until it dies then leave it for me to step on bare footed in the middle of the night. That's happened twice. Now I leave a light on. If the mouse is lucky, I can get it away from them and put it outside before it goes to the RB. Of course there are about 5 outdoor cats it needs to run from then. Mice beware!!! This is not a mouse friendly zone!
