It's terrifying when that happens isn't it, it happened to me a while ago with Holly when I left the lid of his cage up. I came back about half an hour later and saw he was gone, started to panic then I heard rustling noises from the wardrobe. Looked and there he was, investigating some bags of knitting wool I store there. He had somehow managed to climb in the wardrobe door which is around 6 inches off the floor!
Now I'm trying to imagine a hamster taking up knitting.....
