Abstract

A one-piece litter box for an animal includes a container having a base wall with sidewalls extending vertically upward from edges of the base wall to form a hollow interior space. A top opening is formed by upper edges of the sidewalls and an entrance opening is formed in one of the sidewalls. The entrance opening is free of coverings so that the animal can see through the entrance opening. The sidewalls form a height of the container which substantially prevents the animal from seeing over the sidewalls while standing within the hollow interior space so that the animal faces the entrance opening while within the hollow interior space. The tall sidewalls and the fact the animal faces the entrance opening enables the litter box to avoid litter from escaping. The size, shape and location of the entrance opening further enhances retention of litter within the container.

Claims

1. A one-piece litter box for an animal comprising, in combination:

a container having a base wall with sidewalls extending vertically upward from edges of the base wall to form a hollow interior space;

wherein a top opening is formed by upper edges of the sidewalls;

wherein the entrance opening is circular and has a diameter in the range of about eight inches to about ten inches;

wherein the entrance opening is spaced below the top opening of the container and spaced at least six inches above the base wall of the container;

wherein the entrance opening is laterally centered on the sidewall in which the entrance opening is formed;

wherein the sidewalls are free of any openings other than the entrance opening;

wherein the entrance opening is free of coverings so that the animal can see through the entrance opening;

wherein the sidewalls form a height of the container which substantially prevents the animal from seeing over the sidewalls while standing within the hollow interior space; and

whereby the animal faces the entrance opening while within the hollow interior space to see out of the container through the entrance opening and thereby substantially avoid escape of urine feces and litter through the entrance opening while the animal is within the container.

2. The litter box according to claim 1, wherein each of the sidewalls are continuous except for the entrance opening.

3. The litter box according to claim 1, wherein the height of the container is at least fifteen inches.
