Hair (hooman or otherwise) in the bathroom tub or sink.

I don't know what it is about it. Leave it anywhere else and I don't care but I get anal (pardon the pub) about hair in the tub and sink. If I stay at someone's home, I always double-check to make sure I'm not leaving any leftovers. And I always wipe off the sink spout after brushing my teeth to get those little spots off. eeewwwww

Richard, some cat owners just don't get it.
