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. 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.

Claims

1. A biodegradable litter kit for use by an animal comprising:

a foldable box comprising a tray portion for holding litter wherein the tray has a bottom and at least one side extending away from the bottom and further comprising a retractable lid such that the lid may be selectively moved from a position in which it prevents access to the tray portion of the box into a position in which an animal may access the tray of the box to deposit waste in the litter;

a substantially flat false bottom positioned within the tray wherein the false bottom is adapted to hold a layer of fresh litter at a position located between the false bottom of the tray and the retractable lid and not in contact with the bottom of the tray and wherein the false bottom defines multiple perforations wherein the perforations in the false bottom are too small to permit passage of the fresh litter to the bottom of the tray but are sufficiently large as to permit soiled litter which is partially dissolved to pass through the perforations, the false bottom being located a distance sufficient from the bottom of the tray to allow soiled litter to freely fall into and accumulate in a space defined between the false bottom and the tray bottom; and

at least one support member running between the bottom of the tray and the false bottom;

wherein the litter box and the perforated false bottom are all biodegradable and wherein the false bottom is sufficiently rigid to support the weight of the litter while defining the space.

2. The kit of claim 1 further comprising a locking mechanism connected to the tray for holding the lid in a retracted position.

3. The kit of claim 2 where the locking mechanism comprises at least one flap.

4. The kit of claim 3 wherein the locking mechanism uses the friction formed between the at least one flap and a slot formed in a portion of the box to hold a portion of the lid within the flap.

5. The kit of claim 1 further comprising a separator piece positioned between the layer of fresh litter and the lid such that the separator piece seals the litter within the tray when the box is not being used.

6. The kit of claim 1 wherein the layer of fresh litter comprises pine pellets.

7. The kit of claim 1 wherein the lid defines an opening for selectively holding at least one biodegradable waste bag and wherein the kit further includes at least one biodegradable waste bag to be selectively held by the lid until used for disposing solid animal waste.

8. The kit of claim 1 further comprising a biodegradable scooper.

9. The kit of claim 1 wherein the retractable lid is connected to at least part of a side of the tray.
