That story brought back a memory from about 20 years ago. My first cat, Pebbles, came through the cat door one night with a VERY excited look on her face and laid something on the rug just inside the door. I thought it was a mouse until it started flapping it's wings and took off flying. It was a BAT!!! Then both cats were chasing the bat from one end of the house to the other and back while the bat was searching for a way out and I was hiding in the bedroom with the door closed. Finally, I called a friend who came over and simply opened the sliding glass door and waited until the bat circled back to the kitchen. The bat (having radar) flew right out the door! Why didn't I think of that??!!
