To understand Whiskers' background, you have to go read the story of his mother, Dusty the Ducati Cat. That's a cool story.
Whiskers is pure white with blue eyes, is on the large (not fat) side, and a boy. His eyes give him a sort of serene, distracted look, like one would imagine cats of ancient Egypt having. He is the largest of the three "kittens" from Dusty, and his fur is the roughest.
He has been trained by accident to sit up and beg when he wants to be petted, so of course we pet him and the behavior is reinforced. It is so endearing. He doesn't like to be held very much, unless the two of you are hunting spiders on the wall. He has no qualms about plopping down on the floor next to one of the boys in hopes of getting some attention. If you should happen to walk past him without giving him any attention, he will often bat at your hand or arm to remind you of your responsibility.
His favorite toy is a tear-off strip from a milk jug. He hears the ripping sound and will come remind you not to throw it away.
