Abstract

A debris containment system for use with a litter box for containing litter tracked from the litter box by an animal'"'"'s paws includes a collection pan for collecting the litter. The collection pan is formed to include a funnel portion to facilitate quick and easy disposal of the litter. Preferably, the litter containment system also includes a grid member which cooperates with the collection pan to extract debris which is otherwise trapped between the paws of the animal. Further in the preferred embodiment, the collection pan is constructed of a flexible rubber and can be folded about a centerline when litter is being emptied therefrom.

Claims

1. A debris containment system adapted to collect debris carried by an animal'"'"'s paws as the animal exits the litter box, the debris containment system comprising:

a litter box; and

a flexible collection pan positioned in close proximity to the litter box, the collection pan including a generally flat lower surface upstanding substantially linear sidewall and a funnel shaped portion interconnected to and extending upwardly from the generally flat lower surface, said lower surface adapted to be folded about a center line which intersects said funnel shaped portion.

2. The debris containment system of claim 1, wherein a portion of said collection pan is positioned subadjacent to the litter box.

3. The debris containment system of claim 1, further comprising means for extracting debris from the animal'"'"'s paws.

4. The debris containment system of claim 3, wherein said means for extracting debris from the animal'"'"'s paws comprises a grid member disposed in said collection pan.

5. The debris containment system of claim 1, wherein said collection pan is integrally formed of a flexible rubber.

6. The debris containment system of claim 1, further comprising a plurality of walls upwardly extending from said generally flat lower surface, said funnel shaped portion being formed in at least one of said plurality of walls.

11. The method of claim 6, further including the step of returning the debris to the litter box.

7. A debris containment system adapted to collect debris carried by an animal'"'"'s paws as the animal exits the litter box, the debris containment system comprising:

a litter box;

a generally rectangular flexible tray for collecting the debris, said generally rectangular tray including a bottom and four upwardly extending sides;

a funnel portion formed in at least one of said four upwardly extending sides to facilitate pouring of the debris from said generally rectangular tray; and

a grid member disposed within said generally rectangular tray for dislodging the debris from the animal'"'"'s paws as the animal exits the litter box;

said generally rectangular tray adapted to fold about a centerline passing through said funnel portion to facilitate disposal of collected debris.

8. The debris containment system of claim 7, wherein a portion of said generally rectangular tray is positioned subadjacent to the liter box.

9. The debris containment system of claim 7, wherein said generally rectangular tray is integrally formed of a flexible rubber.

10. A method of containing debris tracked by an animal as it exits a litter box, the method comprising the steps of:

providing a collection pan for collecting debris integrally formed to include a funnel portion;

positioning the collection pan adjacent to the litter box;

collecting the debris as the animal exits the litter box;

folding the collection pan along a centerline passing through said funnel portion; and

emptying the debris from said collection pan by tilting said collection pan and pouring the debris through said funnel portion.

12. The method of claim 10, further including the steps of:

providing a grid member for spreading the paws of the animal as the animal exits the litter box; and

placing the grid member in the collection pan.
