I want to agree with Citrine's post. I had a hamster that kept getting out, and one day, I hadn't noticed its cage was empty when I got out of bed. I had made myself a bowl of cereal, and when I walked by the entrance to the living room, I screamed because I saw my hamster, dead, in the mousetrap my brother had put down. I had told him not to do that, and I still get upset thinking about it.
