Bathrooms can work too... just put the toilet paper away and the lid down on the toilet...

and flop the shower curtain over the rod so it can't be played with, and put all the bottles in the cabinet under the sink and tie the handles together so they can't get in and fold up the bottom shelf on the towel rack and wedge it in place with a toothbrush so they can't knock it down and play with the towels and put the litterbox in the bathtub so that when they throw it everywhere it's easy to clean up and and and and.....

you learn to think like a cat...
