either a collar or soak him down with a warm rag every feeding time in the bathroom so you can undo what he does! In other words, he wants badly to be clean, if you wet him before he pulls fur, he'll "lick" first, you can get him clean and by then he hopefully won't want to pull catfood coated fur out! But it is a bad habit that should be stopped before he is pulling for no reason but for boredom...ya know?
