Spent filter media material may be blended with a classic material, such as high-density polyethylene, polypropylene, polybutylene succinate, or polylactic acid, to form a filled plastic composition. The spent filter media may include spent diatomaceous earth, spent perlite, and/or residues thereof. The composition may be performed by co-extruding a mixture of the plastic material and the spent filter media. Surprisingly, the spent filter media may be used as-supplied and without the need to dry the material. The resulting plastic composite material has numerous uses, including, for example, litter scoops and eating utensils.

A pelletized, environmentally friendly animal litter. The animal litter includes birch bark waste in pellet form that is mostly hydrophobic to allow liquid waste to quickly pass therethrough while trapping a small amount of waste therein that adheres to the surface of the pellet and is then absorbed over time. The litter is used in a litter box system that includes a base, a drawer slidably received therein for capturing waste in a preferred absorbent pad and a removeable grate suspended thereover for retaining the litter thereover. The drawer defines a container of sufficient volume to receive all of the litter when a standard amount of litter is used to fill the box which improves ease in changing litter by removing the grate and allowing the litter to drop into the drawer.

An automated litter device having: a base; and a chamber configured for retaining a litter and rotatably supported by the support base, wherein the chamber includes: an entry opening so that an animal can enter and exit the chamber; and a waste opening generally opposing the entry opening configured so that an animal waste passes through the waste opening into the base upon rotation of the chamber; wherein the automated litter device includes one or more of: i) one or more sensors located adjacent to the entry opening which are adapted to sense the presence of the animal within the chamber, the presence of the waste in the base, a level of litter in the chamber, a position of the chamber relative to the base, or any combination thereof; ii) a filtering system configured for reducing, eliminating, and/or preventing, malodors building in the base; and/or iii) a litter dispenser in communication with the chamber to transfer some of the litter to the chamber.

A toilet includes a body portion, a plurality of grains, and a light source. The body portion has a bottom face part and a side face part, and is in a box shape. The plurality of grains are disposed in the body portion. The grains have a water-repellent property. The light source irradiates the plurality of grains disposed in the body portion with light. At least a part of the plurality of grains contain a coloring material that discolors gradually when receiving the light, and exhibit a first color before start of use and exhibit a second color in replacement timing of the grains, the second color being different from the first color.

Provided is a pet cat excrement screening device. The pet cat excrement screening device includes a support base; a drum rotatably mounted on the support base; and a drum driving device mounted on the support base. The drum is configured to rotate between a first position and a second position under drive of the drum driving device, where the rotation angle of the drum is less than 360 degrees. A side wall of the drum body of the drum is provided with a pet inlet. The pet inlet is exposed out of the support base during a rolling process of the drum. A screening mechanism is mounted in the drum. The rear end of the drum is provided with a waste discharge port.

A litter box cover comprises an enclosure adapted to engage and cover a litter pan. The enclosure defines an interior volume adapted to accommodate felis catus (housecat) defecation, and has a feline transit doorway opening into the interior volume and which is adapted to accommodate felis catus ingress into and egress from the interior volume. A hood is movably coupled to the enclosure in registration with the doorway so as to be movable between a canopy position and a chute position. In the canopy position the hood extends outwardly from the enclosure to form a canopy over the doorway, and in the chute position the hood forms a guide ramp for guiding particulate material such as kitty litter through the doorway into the interior volume.

A litter device which is easily operable by individuals with limited mobility or disabilities. A litter device having a base; a waste drawer removably located within the base; a chamber with an entry opening, wherein the chamber is configured to retain litter, is supported by the base, and is located above the waste drawer; and a lift affixed to the base, the waste drawer, or both, wherein the lift is configured to raise and lower the base, the waste drawer, or both.

A combined toileting and hygiene system for a cat, the system comprising: a support device having a first shelving level and a second shelving level, the second shelving level being vertically elevated with respect to the first shelving level; a litter tray associated with the first shelving level; and a container on the second shelving level which is dimensioned to hold one or more hygiene items for the litter tray.

A pet litter box system comprising a base tray with a non-apertured bottom wall and a plurality of sifting trays each with an apertured bottom wall, the sifting trays formed of molded pulp material. The sifting trays and base nest together. The system may include an upper shield seated on the nested sifting trays to contain litter that is kicked up by a cat utilizing the tray system. The shield may be formed of pulp and inverted to receive nested pulp sifting trays to define a transport or storage mode, the shield enhancing the combined structure in the transport or storage mode.

A clumped cat litter filter device and a filtering method thereof are provided. The filter device includes a litter box including a body with a receiving room and a collecting room thereof, a soft cushion, a separating rod transversely arranged between the soft cushion and the bottom wall of the receiving room, and moving along a length direction of the body, a filtering shovel transversely placed above the soft cushion along a width direction of the collecting room, a moving member configured to drive the separating rod and the filtering shovel to move along the length direction of the body, a rotating member installed on the moving member; the present disclosure can prevent the filtering shovel from crushing clumped cat litter, improve a filtering effect thereof, adapt to a variety of cat litter, reduce odor, have advantages of a small size, a low cost, low operation noise and high safety.
