I came home from work to a cat soaked in pee.

Now, I don't know if he peed and then sat in it (what I'm thinking) or just plain peed himself, but while I was gone, I left him locked in the bathroom with food, water and his litterbox. Still no potty in the litterbox, but he was covered in pee. What do I do? It worries me a little more that he hasn't touched his food in the six hours I've been gone more so than the fact that he pottied on the bathroom floor...

Suggestions to make him eat?
