I love hamsters. When I was 10, my hamster broke out of his cage and went down a mouse hole. I was devastated. I put a ton of food in his cage and turned it so the open door faced the mouse hole. In the middle of the next night, I heard a scratching--my hamster was trying to get back in his cage, but was on the side of the cage where the door had been before I turned it! They are clever little buggers.
