If it ended with a 'just kidding' and a rub-down I don't think we'd be nearly as hard on the Nazis about the whole shower thing.
As a young'un my brother and I used to like to carry the cat to the pool and watch her swim. She did not like that much. So, I'm not in a position to judge the 90sec wash.
She used to like to sleep in the dryer after the clothes were warm and dry. She knew how to pop open the door. Used to piss my mom off - cat hair on the clean clothes. I don't think the cat ever got tumbled, though.
