Litter One is the 100% biodegradable, all inclusive, odorless, disposable cat litter system. Each kit includes: litter box, pine pellet litter, scoop, and waste bags. The kit is delivered to your door, all you do is open the box. When your cat urinates on the pellets they turn to sawdust. The sawdust then falls through the patented false floor. When 4-6 weeks has passed, all you do is close up the kit, throw it away, and open up the new one that has already been shipped to your door.
