I have a theory about this, essentially I believe that humans have historically selected cats for breeding by their ability to catch mice, except we measured that based on how often we witnessed the mousing occurring. This caused the behaviour to bring mice home to become especially common, overriding the instinct to actually kill and eat their prey in a significant number of cats. Probably loads of reasons why this is totally wrong, but I enjoy it so whatever![]()
Haha that's a new theory to me, I was always lead to believe it's that domestic cats aren't really hungry so they catch for fun and bring it home to play with basically.
