When we first moved in this house 10 years ago we would let Ripley play in the garage to expell some of his excess energy (boy was he energetic). Once while we were watching a movie with the lights out he came in and sat right in front of the tv and had something in his mouth. We finally realized it was wiggling and he dropped it on the floor. It was a baby mouse and he was playing with it. Anyway, he had no intention of killing it, just playing so we had trap it and release it outside.

One other time he brought a large live mouse in and it got under our kitchen cabinets. I think Ripley had more fun watching us scream and run trying to catch it than he ever had with the mouse.
