When I was little, I used to raid Chip's litter box. It is embarrassing to admit, but for some reason it was an irresistible urging I could not stop. After I put together that every time I went to the litter box I got a bath and my teeth brushed, I stopped. It would have been a lot less painful if Linda bought me S.E.P.
