Any ideas? He's got high quality canned food and all the roast chicken he can eat, plus some elk meat our roommate's dad gifted us. He's down to 10 lbs from his healthy 15lbs. It's not like he can lie around eating eclairs all day, and his appetite is poor. Would kitten formula be good? Chopped deli meat? Straight up lard? He's already got Siamese body structure, but this is getting to the point where it's gross.
