Abstract
A biodegradable litter kit to be used for the collection and disposal of animal waste. The kit includes a litter box having a tray portion and a retractable lid. The tray has a bottom and at least one protruding side to which the lid is connected. The box includes a perforated false bottom positioned within the tray for holding a layer of fresh litter above the bottom of the tray. The perforated false bottom permits for the passage of soiled litter but prevents the passage of fresh litter to the bottom of the tray thus keeping a layer of fresh litter accessible for use by an animal. A separator piece may be included for selective positioning over the layer of fresh litter to maintain it within the box when the box is not in use. The box may include biodegradable accessories.
