Well, as I thought the cat came back. It killed a Chipmunk and left it for us at the front door on the deck. Nice. So I picked it up and threw it into the woods for the foxes to find. I called the owners just to let them know that the cat was back and not to worry I was not feeding it or letting in the house. No call all day. So guess what? My wife lets in and it slept in the basement last night.
