Lol, Jerry. Almost blends in with the whole Clinton definition of what "is" is, doesn't it? It has been my experience that male cats for some reason like to "nibble" -- nothing serious that would draw blood or even leave a mark, but they do seem to have a propencity to make sure you know they have teeth. None of the female cats I've ever had over my lifetime (four) ever did that to humans -- only to each other. I guess it's a male thing.
