The Football

The other day I posted about my little cat, Calumet being a footballer. She has a multitude of toys, but lately that soft little football has been her favorite. The other day I went down to the basement and saw it laying at the bottom of the stairs. The next day I saw it on the second floor, in the library. Today, it's on the first floor near my computer-but close to the kitchen...and not far from the basement stairs. Where will it turn up next?
