Games with cardboard boxes. Yesterday I received a delivery which came in a rectangular box. I often create little forts for the cats out of boxes and this one seemed perfect for games. I cut a doorway at one end and then another in the side rather than just making a tunnel. Here is Doyle checking it out and considering whether to pounce on the camera, which she didn't, instead she came to the doorway I was peeking through to see what I could see.
