I've always had a fear of that happening to me so I've always propped the door with something so it wouldn't. He said he knew I was on the computer and it would be awhile before I'd start looking for him. He was thinking as a last resort to climb out the SMALL window in the back in order to get out if he was in there too much longer. He would have had to go head first and that wouldn't be pretty. We both got a good laugh out of it but that was because he hadn't been in there too long. I guess he'll either fix the door to open from the inside or prop it open the next time.
It is never dull around our house.
