DETAILED DESCRIPTION OF THE INVENTION

[0031] The present invention provides improved pet and cat litter boxes. Of course, it is known in the art to provide litter boxes so as to allow a sanitary area for a cat, or other small pet, to urinate and/or defecate. These litter boxes provide a structure in which to house cat litter or other absorbent material for receiving the pet waste.

[0032] As set forth in FIGS. 1-7 various designs and embodiments of the cat litter box 10 of the present invention are provided. Generally, as illustrated in FIG. 1 the cat litter box has a top 12 and a bottom component 14. The top component 12 further includes a part that is hinged. The hinged portion 16 allows one access to an interior of the cat litter box 10. In the illustrated embodiments, the hinged top portion 16 includes an opening 18 for the cat, or other pet, to enter and exit.

[0033] Preferably, the litter box is nestable. To this end, the top 12 when not in use, can be inserted into the bottom 14. This allows multiple litter boxes to be stacked on top of one another. The nestable feature provides a compact design for the retailer in stocking/dispensing the litter boxes to customers.

[0034] Preferably, the front of the litter box 10 has a friction snap 20 to lock the top to the bottom. Thus, the pet can enter and exit the litter box 10 without the top portion opening. The top 12 of the litter box 10 is hinged to the remaining portions by, preferably, at least two hinges 22 to allow it to swing up.

[0035] The litter box 10 defines an interior for receiving the cat litter. This interior includes a bottom portion 24 on which the cat litter is located. Preferably, the bottom 24 of the cat litter box 10 is textured. Preferably, there are a minimum of eight types of textured bottoms to prevent the cat litter from sticking to the bottom of the container.

[0036] If desired, the bottom portion 24 of the cat litter box 10 can include a disposable liner (not shown). Also, in an embodiment, the inside bottom texture is chosen to reduce the cat litter from sticking to the bottom of the container which makes it easier to clean and to remove clumped cat litter. Preferably, the shape of the bottom piece has a waste and is not square or oblong.

[0037] To reduce smell within the cat litter box 10 side vents 26 are provided. The side vents 26 increase the air flow within and through the interior. Moreover, by being placed on the side they prevent cat litter from being kicked out by the cat. A variety of vents can be provided as illustrated in FIG. 7 as A through F.

[0038] In order to ensure that the top portion 12 of the cat litter box 10 is coupled to the bottom portion 14 side locks 28 are provided in a preferred embodiment. The side locks 28 are preferably pressure side locks to removably lock or secure the top to the bottom.

[0039] In order to allow the cat litter box 10 to be easily transported, preferably a handle 30 is located on the top of the litter box. The handle 30 is used to carry the litter box. Preferably, the handle 30 is molded to fit four fingers. In an embodiment, the handle 30 is molded to encompass a finger grip. FIG. 6 illustrates a number of embodiments of the handle.

[0040] The opening 18 of the cat litter box 10 is designed to allow the cat, or other pet, to be able to enter the litter box. A variety of different openings can be utilized. FIG. 5 illustrates six embodiments of the opening A, B, C, D, E and F. For example, FIG. 5C illustrates the shape of a cat's face as the opening to the cat box.

[0041] Preferably, located at the top of the litter box 10 is a charcoal vent 32. The combination of the side vents 26 and the front opening 18 allow more efficient air flow for the charcoal. This is believed to result in a longer-lasting charcoal filter. In this regard, it is believed that the charcoal filter will only have to be replaced every month or two.
