Litter One is the 100% biodegradable, completely self-contained, disposable litter system for cats. Each kit includes: litter box, pine pellet litter, scoop, and waste bags. The kit is delivered right to your door ready for use. All you need to do is open the box and set it out. The pellets turn to sawdust when the cat urinates. The patented false floor allows for the sawdust to fall through and not worry the consumer about tracking and buildup. The pine pellets completely neutralize the cat urine odor and provide a natural pine scent. When 4-6 weeks has passed, all you do is close up the kit, place it in the recycle/trash bin, and open up the new one that has automatically been shipped to your door.
