The other day I cut up some watermelon and mixed it in with Skeletor's food.
Oh well, if it's cheap and good for him, he can have at it!
Other things I've added to get him to eat include:
Pecan meal, potato flakes, peanuts, peanut butter, olive oil, Parmesan cheese, tuna juice, lunch meat, chicken broth, leftover noodles, leftover rice, raisin bran crumbs I accidentally spilled on the counter, cooked liver, raw egg, cooked egg, and even wet dog food.
Ian tricked him into eating plain dry food by tossing a few pieces of kibble in the air for him to catch. He gradually tossed them closer and closer to the food dish and then into the dish...
Maybe one of these days I'll find the magic dry food that he just loves.
