Abstract

An animal litter box which is configured to urge an animal toward a desired orientation in the litter box. The litter box includes a floor, a sidewall extending upward from the floor to define an interior of the litter box, which sidewall has an interior sidewall surface facing the interior of the litter box, and a cue associated with a selected portion of the interior sidewall surface, which cue urges the animal toward the desired orientation.

Claims

1. An animal litter box comprising:

(a) a floor;

(b) a sidewall extending upward from the floor, the sidewall surrounding an interior of the litter box, the sidewall having an interior sidewall surface facing the interior of the litter box; and

(c) a cue associated with a selected portion of the interior sidewall surface, for urging an animal toward a desired orientation in the litter box.

2. The litter box as claimed in claim 1 wherein the sidewall is comprised of a front wall and an opposing back wall and wherein the back wall is comprised of the selected portion of the interior sidewall surface.

3. The litter box as claimed in claim 2 wherein the front wall defines an entrance gap for facilitating ingress to and egress from the litter box by the animal.

4. The litter box as claimed in claim 3 wherein the selected portion of the interior sidewall surface is aligned with the entrance gap such that the selected portion of the interior sidewall surface is substantially opposite to the entrance gap.

5. The litter box as claimed in claim 3 wherein the sidewall has an upper end and a lower end and wherein the entrance gap extends vertically from a lower gap end above the lower end of the sidewall to the upper end of the sidewall.

7. The litter box as claimed in claim 1 wherein the sidewall is comprised of a front wall and an opposing back wall, wherein the front wall has a length, wherein the back wall has a length, and wherein the length of the back wall is greater than the length of the front wall.

8. The litter box as claimed in claim 7 wherein the sidewall is further comprised of a left side wall extending between the front wall and the back wall and wherein the sidewall is further comprised of a right side wall extending between the front wall and the back wall.

9. The litter box as claimed in claim 8 wherein the sidewall is further comprised of a left front corner between the left side wall and the front wall, wherein the sidewall is further comprised of a right front corner between the right side wall and the front wall, and wherein the left front corner and the right front corner are oblique corners.

10. The litter box as claimed in claim 1 wherein the sidewall has an upper end and wherein the litter box is further comprised of a rim projecting laterally from the upper end of the sidewall.

11. The litter box as claimed in claim 1 wherein the cue is comprised of a visually perceptible irregularity.

12. The litter box as claimed in claim 1I1 wherein the visually perceptible irregularity is comprised of a shape associated with the selected portion of the interior sidewall surface.

13. The litter box as claimed in claim 11 wherein the visually perceptible irregularity is comprised of a pattern associated with the selected portion of the interior sidewall surface.

14. The litter box as claimed in claim 11 wherein the sidewall is comprised of a front wall and an opposing back wall and wherein the back wall is comprised of the selected portion of the interior sidewall surface.

15. The litter box as claimed in claim 14 wherein the front wall defines an entrance gap for facilitating ingress to and egress from the litter box by the animal.

16. The litter box as claimed in claim 15 wherein the selected portion of the interior sidewall surface is aligned with the entrance gap such that the selected portion of the interior sidewall surface is substantially opposite to the entrance gap.

17. The litter box as claimed in claim 15 wherein the sidewall has an upper end and a lower end and wherein the entrance gap extends vertically from a lower gap end above the lower end of the sidewall to the upper end of the sidewall.

18. The litter box as claimed in claim 15 wherein the sidewall has a height and wherein the height of the sidewall is between about six inches and about twelve inches.

19. The litter box as claimed in claim 1 wherein the cue is comprised of a discontinuity in the interior sidewall surface.

20. The litter box as claimed in claim 19 wherein the discontinuity is comprised of a protrusion which extends laterally a protrusion distance toward the interior of the litter box.

21. The litter box as claimed in claim 20 wherein the sidewall has an upper end and a lower end and wherein the protrusion extends vertically from a lower protrusion end above the lower end of the sidewall to an upper protrusion end adjacent to the upper end of the sidewall.

22. The litter box as claimed in claim 21 wherein the protrusion distance at the lower protrusion end is less than the protrusion distance at the upper protrusion end.

23. The litter box as claimed in claim 20 wherein the sidewall is comprised of a front wall and an opposing back wall and wherein the back wall is comprised of the selected portion of the interior sidewall surface.

24. The litter box as claimed in claim 23 wherein the front wall defines an entrance gap for facilitating ingress to and egress from the litter box by the animal.

25. The litter box as claimed in claim 24 wherein the selected portion of the interior sidewall surface is aligned with the entrance gap such that the selected portion of the interior sidewall surface is substantially opposite to the entrance gap.

26. The litter box as claimed in claim 24 wherein the sidewall has an upper end and a lower end and wherein the entrance gap extends vertically from a lower gap end above the lower end of the sidewall to the upper end of the sidewall.

27. The litter box as claimed in claim 24 wherein the sidewall has a height and wherein the height of the sidewall is between about six inches and about twelve inches.

28. The litter box as claimed in claim 25 wherein the sidewall is comprised of a front wall and an opposing back wall, wherein the front wall has a length, wherein the back wall has a length, and wherein the length of the back wall is greater than the length of the front wall.

29. The litter box as claimed in claim 28 wherein the sidewall is further comprised of a left side wall extending between the front wall and the back wall and wherein the sidewall is further comprised of a right side wall extending between the front wall and the back wall.

30. The litter box as claimed in claim 29 wherein the sidewall is further comprised of a left front corner between the left side wall and the front wall, wherein the sidewall is further comprised of a right front corner between the right side wall and the front wall, and wherein the left front corner and the right front corner are oblique corners.

6. The litter box as claimed in claim 31 wherein the sidewall has a height and wherein the height of the sidewall is between about six inches and about twelve inches.
