So I picked up a variety of foods today to try. Started off with the Merrick Purrfect Bistro Beef Pate for dinner tonight and he has absolutely inhaled it, ate the whole 5/8can in a single sitting. Now to see if he's just faking me out or if he's going to eat it for +5 and breakfast also. Plus, our other cat came sniffing at the bowl after he was done and licked up the scraps so I might finally be able to start feeding them the same food again which would be great and go a long way towards fattening him back up.
