Abstract

A litter box assembly is provided that includes a tray for containing litter and a shield that can be removably mounted to the tray for reducing or preventing the scattering of litter material outside the tray. The shield effectively extends the height of the tray along three sides and can be removed for cleaning between litter changes. A self supporting shield for a litter box tray is further provided as well as a method for reducing the scattering of litter material by a cat or other animal.

Claims

1. A litter box assembly comprising:

a tray for containing litter material, the tray including a bottom wall, opposing pairs of side walls, and a peripheral lip joined to the side walls, and

a shield removably mountable within the tray such that it can extend above the tray and engage the bottom wall of the tray, the shield including a rear panel, two opposing side panels and an open end, wherein a width and length of the shield approximate a width and length of the tray, and a height of the shield is about twice a height of the tray, wherein the panels of the shield are positionable within the tray to prevent or reduce scattering of litter material outside the tray by an animal using the tray.

2. A litter box assembly as described in claim 1 wherein the shield is mounted to the tray and further including litter material within said tray.

3. A litter box assembly as described in claim 1 wherein the bottom wall and opposing pairs of side walls of the tray define a generally rectangular enclosure, the side walls of the tray being about five inches in height.

4. A litter box assembly as described in claim 3 wherein the height of the shield is at least about twice the height of the tray.

5. A litter box assembly as described in claim 3 wherein the side panels of the shield taper downwardly in height in a direction away from the rear panel.

6. A litter box assembly as described in claim 5 wherein the height of the shield is at least about twice the height of the tray.

7. A litter box assembly as described in claim 3 wherein each of the side panels of the shield includes an end secured to the rear panel.

8. A litter box assembly as described in claim 7 wherein the height of the shield is at least about twice the height of the tray and the side panels of the tray taper downwardly in height in a direction away from the rear panel.

9. A litter box assembly as described in claim 3 wherein the shield engages the bottom wall of the tray.

10. A method of preventing or reducing the scattering of litter material used by an animal comprising:

providing a tray having four generally vertical side walls, a bottom wall and a peripheral lip extending from the generally vertical side walls of the tray;

filling the tray with litter material suitable for burying animal waste; and

removably inserting a self-supporting shield within the tray to provide three generally vertical wall surfaces such that the shield is supported by the bottom wall of the tray, wherein the shield includes a rear panel and two opposing side panels secured to the rear panel, wherein the wall surfaces each have a height substantially greater than the heights of the side walls of the tray with two generally vertical side wall surfaces being in opposing relation to each other and the other generally vertical side walls being substantially perpendicular to the two opposing generally vertical wall surfaces.

11. A method as described in claim 10 including the step of mounting the shield such that the rear and opposing side panels adjoin three of the four generally vertical side walls of the tray, the side walls of the tray being about five inches in height.

12. A method as described in claim 10, wherein the generally vertical side walls of the tray are about five inches in height and, with the bottom wall, define a generally rectangular enclosure.

13. A method as described in claim 10 wherein the shield is a self supporting structure including a rear panel and two opposing side panels secured to the rear panel, including mounting the shield within the tray such that the shield engages the bottom wall of the tray.

14. A method as described in claim 10 including mounting the shield to the tray such that the shield adjoins at least three of the side walls of the tray.
