The Green Pee Cat Litter System uses a non-porous filler, pea gravel in a perforated tray sitting in a second tray that contains an absorbent layer of newspaper ...
Holes are drilled in one tray
Newspaper and baking soda are put in the bottom tray
The trays are combined
The cats are trained by using pea gravel on one side and cat litter on the other
