Update: Murfee still hasn't eaten or had a drink. He wouldn't come out of the bathroom all night. I did lay on the floor with him but neither of us slept. I finally got him to come and lay on my shoulder and he is asleep right now. After a little nap, I am going to try to entice him with food and water. If that doesn't work, we will go back to the vet. I sure don't want him to get dehydrated.
