There is a cat that lives across the street from us who is all black with white paws. We call him "Sox". We tried to adopt him and have him live in a cardboard box when we thought he was a stray - turns out he lives across the street! Anyways Sox has been famous in our house for quite some time - and our cats have grown to appreciate the occasional visits by Sox. He "tap dances" outside our windows and initially Sox caused our cats to get really upset and even want to fight each other - but now they just watch Sox for the most part. Occasionally Brady likes to attack the window with no word of warning.. but overall it's fun for everyone.
