He was hiding most of Saturday night and all day Sunday, so I decided to get drastic and drag him out of his hiding place, because I knew he hadn't eaten or used the litterbox. So despite what I know to be contrary advice, I removed him from his hiding spot and put him in a carrier for a little while to eat. He ate a whole can of food and then I re-released him into the bathroom (much cozier than the living room apparantly for my scaredy cat). He has a little kitty house in there that he hides in and then meows his head off for me to come in and sit on the floor. When I do he comes out and headbutts me until I pet him then he rolls over on his back for me to rub his tummy. He's so adorable, but I wish I knew what has him so freaked out to be out in a "big" room.
