Nope. I'm 100% cat. And by no means the biggest to have lived in this house... "Big" (now gone) was part Maine Coon and pushing 20lbs much of the time. My friend Kramer was long and lean... and weighed about 16lbs. "Raddish" was the biggest of the girl cats at about 17lbs and NOT fat. Maybe it's something in the water?
