Fuzz Bucket

I am going to digress a bit today.  Fuzz Bucket is not one of the colony.  He is not one of my cats. He is, I think, an apparition.  Fuzz has been appearing for about a year.  I say appearing because he never seems to move.  He sits.  He waits. He scares me.

I've actually seen Fuzz, or a vision of him, down the street.  He must live elsewhere and only appears at my house to stare.  Why, I ask you? The other cats are oblivious to him.  There is never any interaction, human or animal.  I think he's waiting for something...but what!
