Sometimes you have to change the protein to see if they like it better, or add some flavoring to it. We had a bully that all of a sudden they didn't like the food, so we put a little Feta cheese in the food and they scarfed it up. So you might try that, plus there are other flavoring a you can get at petsmart or petco. Plus do not give them people food at all. Unless you scrabble some eggs to add to their food.
