Well, this is probably more mouse behavior than cat behavior. But our cats have caught a couple of mice in our basement, and have left me wondering about something... the mice they've got have been very dead, but also don't seem to have a scratch on them. No signs of being bloodied, beaten or scratched. So, I'm just curious what they died of. Is it possible the mice actually get "scared to death" when a cat gets them cornered? Has anyone ever heard or read anything about this? Just one of those silly questions that's not worth thinking about but I can't seem to get out of my head!
