The cat was probably trying to give you the mouse as a gift. A way to sort of pull its weight around the house. We had a couple cats growing up that would do that. One would drop dead mice in your bed while you were sleeping.Rambler said:^^^I love cats but they're masochistic shits. We had one years ago that caught mice, ate just their ears, tail & feet & then left them where my wife was sure to step on them in the morning. I swear that cat enjoyed it all.
