Abstract

A litter box for cats or other domestic animals, which comprises three pans insertable into each other to form a stack. The position of the pans is interchangeable and each pan has openings in its inferior part for filtration of an absorbing material used to solidify and absorb the organic wastes. The openings of each pan are located at positions different from the openings of the other pans in such a manner that the openings of each pair of adjacent pans be vertically out of line. One advantage of this litter box is that it is not necessary to use a shovel to pick up and dispose of the organic wastes.

Claims (13)

1. A litter box for cats or other domestic animals, comprising:

at least three pans insertable into each other to form a stack, the pans being interchangeable within the stack, each pan comprising a floor and a peripheral wall forming together an open container capable of receiving a layer of an absorbing material for absorbing and solidifying organic wastes, the floor of each pan comprising cavities that are aligned vertically with the cavities made in the other pans when the same are inserted into each other; and

a plurality of openings made within the floor of each pan, the openings of each pan being located at positions different from the openings of the other pans in such a manner that the openings of each pair of adjacent pans be vertically out of line, each opening being sized to retain the organic wastes while allowing the absorbing material to pass therethrough.

2. The litter box according to claim 1 , wherein the openings are made exclusively in the bottoms of some of the cavities.

3. The litter box according to claim 1 , wherein the openings are made in all the cavities, said openings being the shape of slim rectangular slots that are located in such a manner that the openings of each pair of adjacent pans be out of line vertically.

4. A litter box for cats or other domestic animals, comprising:

at least three pans insertable into each other to form a stack, the pans being interchangeable within the stack, each pan comprising a floor and a peripheral wall forming together an open container capable of receiving a layer of an absorbing material for absorbing and solidifying organic wastes, the peripheral wall of each container comprising an upper rim opposite to the floor, the floor of each pan comprising cavities that are aligned vertically with the cavities made in the other pans when the same are inserted into each other, each pan comprising a handle projecting outwardly from a portion of its peripheral wall;

a plurality of openings made within the floor of each pan, the openings of each pan being located at positions different from the openings of the other pans in such a manner that the openings of each pair of adjacent pans be vertically out of line, each opening being sized to retain the organic wastes while allowing the absorbing material to pass therethrough, said handles being positioned in such a manner as to be aligned when the pans are inserted into each other and the openings of each pair of adjacent pans are vertically out of line, said handles then acting as positioning indicators; and

attaching means for holding together the rims of all the pans.

5. The litter box according to claim 4 , wherein the openings are made exclusively in the bottoms of some of the cavities.

6. The litter box according to claim 5 , wherein each pan is made of molded plastic material.
