those cats can be darn right sneaky! I call them tuxedo cats also, but I've always had pure black ones (w/little tiny white spot on chest). My old guy who passed a few years ago was obsessed with chewing on anything plastic..the crinklier the better. The youngster (now 14) has a wonderful habit of anytime she expels a hairball she poops about 6 ft away from it. They always come in twos. That one I have not figured out.
