A few years ago (WWII!)we had a cat named Furball. When he was a kitten, the name fit him very well, but when he got older we should have changed it to "Fifteen pounds of muscle, teeth, claws and scar tissue" But that was too long, so we kept calling him Furball. He was so gentle he would sit on you lap and purr for hours. But he was so tough he whipped up on all the cats and dogs in the neighborhood. It was really funny watching a large dog being chased by a cat. I don't know that he ever lost a fight, but one day he left and didn't come back.
