I'm really a dog person, except . . .

There is an old white kitty that lives on my front porch.  He has several names - I call him "not my cat;" or white kitty.  He has a proper name, but I don't remember it.  White kitty was my neighbor's teen daughter's cat.  The teen grew up and moved away.  So did white kitty.  White kitty started hanging out on my front porch while some construction was going on at his house.  For the past 7 years, white kitty has been my "not my cat." I feed him.  I make him a warm bed in the winter.  I guess he is my cat.  No, I guess I'm his person.
