Herman does eat people food occasionally. He loves turkey breast. Suprisingly enough, he smells better when he eats turkey or chicken breast. I don't think it will give him all the nutrition he needs, so I don't just feed it to him all the time. He is a strictly indoor cat (scared of birds and all) so I know he's not getting mice or food. Sometimes he actually plays in his box and then it's bath time, but no waste on his rear.
