This evening, our cat was interested in our front door, and Diana peeked out and saw this set of tiny footprints from our car to our door. After Diana took the picture and shut the door, I heard scratching at it! Then our cat was back to the door, and I opened it up, and the cat went out, felt the cold, and came right back in! I am sure that there was a mouse visitor knocking on our door. I hope that he or she found a safe place to spend the night!
