Abstract: A pet sanitation station comprises a housing having a main chamber a sliding plate forming a chamber floor located in a collar which sits on a receptacle for collecting soiled litter. A hopper for storing and dispensing clean litter is located in the housing directly above the main chamber. An apertured sliding plate dispenses a controlled amount of clean litter from the hopper onto the floor the main chamber.

Abstract: An apparatus and method are provided for partially automating the use of litter bags for animal litter. The method makes use of apparatus including two pivoted arms over the tops of which the upper portion of a litter bag may be folded when the arms are extended upwardly. The arms are then pivoted downwardly to spread out the litter bag either in a litter pan or upon the base upon which the arms are pivoted. The litter containers used are in the form of bags which-may be prefilled and have an interior sheet over the litter to prevent dusting and pockets in the upper edge to facilitate attachment to the pivoted arms of the support apparatus.

Abstract: A new and improved cat litter box apparatus includes a floor member and four walls projecting upward from the floor member. The four walls and the floor member define a container for litter material. A removable and replaceable cover member is capable of being fitted onto the four walls for sealing the litter within the container. A discharge outlet is located in one the four walls for permitting the litter within the container to be discharged from the container. Three of the four walls include grooves and one of the four walls includes a slot for receiving the cover member for sealing the litter within the container. A lifting handle is attached to one of the four walls for lifting the container. A receptacle slot, located under the floor member, receives the cover member when the cover member is not installed on the four walls for sealing the litter within the container.

Abstract: A kitty litter disposal device for hygienically reusing kitty litter in a litter box has a plurality of fine-meshed nets in juxtaposition with the bottom of the litter box in the box. Each net covers the bottom of the litter box and extends along the inside surfaces of the sides of the litter box, over the lip of the litter box and along at least part of the outside surfaces of the sides. Net fasteners in the nets and on selected sides of the litter box releasably fasten the nets in position in the box, whereby kitty litter in the litter box on the nets is siftable via the uppermost of the nets upon unfastening of the uppermost of the nets and manual holding of same in the box at a distance above the remaining ones of the nets thereby to pass the kitty litter into the box.

Abstract: A system which separates the pet excreta collection, storage and disposal functions wherein each individual component used to perform each of these functions is optimized for its intended purpose. The system of the present invention permits almost indefinite recycling of the substantially nonsorbent, nonclumping granular litter material used by the animal to bury its solid excreta. The combination of the present invention includes a porous filtering member exhibiting a pore size which will readily permit the granular litter material to pass therethrough, yet retain substantially all of the solid animal excreta coming in contact with the fitering member during the filtering operation. A protective member capable of substantially resisting damage when subjected to digging or clawing by animals is secured in superposed relation to and completely overlies the uppermost surface of the porous filtering member.

Abstract: A litter box envelope comprising a top sheet and a bottom sheet bonded to each other along the side edges and one end edge of each so as to leave an open end for receiving a litter box therein; a facing sheet of tear resistant, claw and scratch-proof material of non-woven nylon fibers, which are spun-bonded and heat treated. The facing sheet is adapted to receive litter material therein.
