That's a great picture! I think you need to talk to the cats about their "job description".
Black toilets are nice looking--one of our bathrooms has a black double-sink top, black toilet, black bathtub, and black (marbleized) shower surround--with white floor and tub deck tile. It's very pretty, and I highly recommend it to anyone who has a full-time maid in their employ!! Thankfully, it is our least-used bathroom!
