Debbie stay calm- the main thing is about peeing and you'll know that by tomorrow. It's a good sign if she is eating and acting normal.

Don't let it haunt you that she slept on that spot- she didn't feel purrfect- so she wanted to be alone and that spot obviously is best (in terms of Feng Shui) for cats who don't feel ok.
