An animal litter box includes: an upper container including a liquid passage portion having holes through which urine passes downward; a tray on which an absorbent body is disposed to absorb the urine that passes through the liquid passage portion; a lower container that supports the upper container from below and that detachably accommodates the tray; and a ventilation fan disposed in the lower container and that sends internal air in the lower container to an outside.

Apparatus and methods are disclosed for detecting motion between two subassemblies, for example in or near a litter box. A first subassembly includes a first frame adapted for supporting a receptacle. A second subassembly includes a second frame adapted for resting on a steady surface. Connecting members connect the subassemblies such that relative movement between them can occur. At least a first position indicating member is attached to one the subassemblies and at least a first detector is attached to the other of the subassemblies. The detector is positioned proximate the first position indicating member so that changes in relative position are detected. Preferably, the device includes a second position indicating member and a second detector for detecting more precise changes in relative position. It is also preferred for each position indicating member to include a patterned marker.

A waste receptacle (1) for animal excreta, the waste receptacle (1) comprising: a housing having a base and at least one sidewall (3) upstanding from the base so as to define an internal housing void (7) in which a liner (9) can be provided; and a liner (9) insertable into said internal housing void, the housing liner (9) having a liner base and at least one liner sidewall supportable in use so as to be generally upstanding from said liner base, the liner base and said at least one liner sidewall cooperating to define an internal liner void for the receipt of animal litter; wherein the housing (1) and the liner (9) each comprise access ports that cooperate with one another when the liner is received (9) within said internal housing void (7) to allow an animal to enter the housing (1) and access litter provided within said liner void, the at least one liner sidewall further comprising a pocket (27) for the storage of a litter scoop, said pocket (27) being provided on an external face of the at least one liner sidewall that is adjacent an internal face of said at least one housing sidewall when the liner is inserted into said internal housing void.

A litter evacuation door system includes a door opening defined through a side wall portion of a litter tray, a sliding door guide structure surrounding the door opening, a door slidably engaged in the sliding door guide structure, the door is user selectively movable between a closed and open position, a bag engaging collar extending around an exterior side edge of the door opening and configured for engaging the opening edge of a litter collecting bag, the bag engaging collar further defining a bag collar engaging groove for slidably receiving therein the bag collar plate of a disposable litter collecting bag.

A litter vessel assembly includes a vessel including a bottom for reception of broken down litter. The bottom is positioned over a confined volume and is configured with slots and a hatch. The slots are configured to disable unbroken down litter from falling downwardly therethrough into the confined volume from the vessel and enable broken down litter to fall downwardly therethrough into the confined volume from the vessel. The hatch is adjustable between a closed position closing a hatchway to the confined volume and an open position opening the hatchway to the confined volume.

An animal toilet includes a body portion, and a partition portion. The body portion has a bottom face part and a side face part, and is in a box shape. The partition portion is in a plate shape, and divides the inside of the body portion vertically. The partition portion has a through hole that allows urine to pass therethrough. The thickness of the partition portion in a surrounding part around the through hole is smaller than the thickness of the partition portion in a remaining part that is the part other than the surrounding part. The surrounding part around the through hole inclines downward toward the through hole.

The present invention relates to a toilet training device for a pet. More specifically, the present invention relates to the toilet training device for the pet, which allows the pet to receive the automatic toilet training to save an owner's time for training the pet in connection with the defecation, wherein it enables the more correct determination about the pet's defecation state, while simplifying a sensor plate configuration for detecting the pet's defecation state, so that it is possible to reduce manufacturing cost thereof. The present invention for obtaining the above goals comprises a defecation unit which receives pet's excrement; and a feeding unit for supplying snack in case that the pet defecates on the defecation unit, wherein the defecation unit comprises a sensor plate for sensing the defecation state of the pet and a collecting member located below the sensor plate.

A generating device of simulating a particulate environment for an experimental animal includes an experimental chamber. An ultrasonic atomization device is installed at the bottom adjacent to the center of the experimental chamber. The upper side of the ultrasonic atomization device is connected to a guide device for guiding particles. The guide device includes an air seal cover, and a micro fan is installed inside the air seal cover to drive the movement of particles generated in the ultrasonic atomization device. Air guide pipes are fixedly connected to a side wall of the air seal cover. The generating device has good sealing performance, and can generate a variety of particle simulation environments to accurately and effectively simulate the biological effect of particles in the animal body. The generating device can improve the particle simulation environment, reduce the deviation of experimental data, and ensure the accuracy of the overall experimental data.

A pet system according to various aspects of the present technology may comprise a pet apparatus configured to attach to a pet door, comprising an enclosure comprising a wall. The wall may include an entrance defined therethrough. A pet door interface may be connectable to the pet door. The pet door interface may define a substantially enclosed portal between the pet door and the entrance.
