  • Patent number: 10849309
    Abstract: A combined litter box and cleaning sieve is provided including a base structure and a sieve member. The base structure includes a bottom wall and side wall(s) which extend upward from the base wall except in one portion to leave an open side for receiving the sieve member therethrough. The sieve member includes a back wall section for extending across the open side of the base structure, a screen portion and upstanding handle. In use, the sieve member is inserted in the base structure and litter filled on top thereof. The litter can be cleaned of waste by lifting the sieve member by the handle whereby clean litter sifts through the screen portion and waste is collected on the screen which can then be disposed of. Afterward, the empty sieve member is placed back into position through the receiving side of the base structure for further use.

  • Patent number: 10653106
    Abstract: A litter box includes upper and lower shells having corrugations formed therein that strengthen the walls of the shell and that enable the walls themselves to be relatively thinner than would be required in the absence of corrugations. The relatively thinner walls thus enable the litter box to be formed from less material. The corrugations are configured to enable molding with conventional two-part molds. An upper shell portion has a handle integrally molded therein. When assembled, the upper shell sits atop the lower shell, and the line of junction between the upper and lower shells is oriented oblique to a bottom surface of the lower shell and thus oblique to a floor upon which the litter box may sit. The oblique angle enables a relatively low step-over height at the front and a relatively high height at the rear to resist the penetration of urine.

The commercial plumbing version has a conventional commercial flushing valve and lever, either hand or foot operated. The residential version has an oversized conventional toilet tank complete with flush handle and flapper valve. To flush, the pet owner activates the actuator to dislodge the cover from the drain and flushes the pet waste and absorbent material down the drain. The user then replaces the plug and refills the bowl with about an inch of fresh litter.

  • Patent number: 8863693
    Abstract: Animal toilets presently do not have an automated method of cleaning the toileting surface and disposing of wastes. The animal toilet disclosed herein is equipped with a permeable toileting surface, a catchment surface underlying the toileting surface to collect and channel liquids, and a drain. The toileting surface may be equipped with a rinsing element to rinse wastes from the toileting and catchment surfaces. The drain may be further equipped with tubing to convey the liquids to a convenient disposal location. The animal toilet may be equipped with a moving toileting surface, which results in improved rinsing, and potential solid waste collection. In all embodiments, absorbent material may be used in place of permeable material for the toileting surface, which may not require any rinsing. The solid waste disposal may be automated through the use of rinse water and disposal tubing routed to the proper disposal location.

  • Patent number: 8857375
    Abstract: A litter box system comprises an imitation bed of loose cat litter that includes a layer of actual cat litter granules bonded to a sheet of flexible material. In some examples, the relative thicknesses of the sheet of material and the layer of cat litter is such that the imitation bed of loose cat litter has substantial urine holding capacity yet remains sufficiently flexible. In some examples, the sheet of material includes an image of loose cat litter underneath the bonded layer of cat litter so that if some of the cat litter layer is scratched off, the imitation bed will still appear to be fully covered with cat litter granules. In some examples, the sheet of material includes integrally formed bumps that resemble cat litter granules.

  • Publication number: 20140209033
    Abstract: The present invention consists of a two part system for controlling pet odor. The first part is an enzyme spray with a high concentration of microbes that consume ammonia. The second part of the system is absorbent granules that also contain the ammonia consuming microbes. When used in conjunction with each other, the system is ten times more effective at controlling pet odor than comparable one part systems. The microbes can penetrate into the cracks and crevices of most surfaces to further reduce the source of pet odors. The system also works to control moisture which allows for proper pet hygiene by reducing molds, fungus, insects, and parasite infestations. The system is a non-toxic and environmentally friendly product that will not harm pets if ingested. The system can be used with cat litter boxes, pet bedding, dog kennels, or any indoor area where pets expel their waste.

  • Patent number: 8733286
    Abstract: A litter box having apparatus for catching and returning litter being tracked from the litter box, and a method of assembling the litter box. The litter box includes a container for containing litter. An opening and a litter return window are formed in the container. Stair steps defining slots therebetween extend from the opening. A litter return slide is disposed beneath the slots and slopes downward towards the litter return window. As the animal traverses the stair steps, litter adhering to the paws of the animal is dislodged and falls through the slots to be caught by the litter return slide. The dislodged litter travels down the litter return slide and through the litter return window so as to return the dislodged litter to the litter container. Thus, the animal is prevented from tracking litter beyond the litter box, so that litter cleanup is reduced and sanitation is enhanced.
