Abstract: The disclosed system, methods, and apparatus relates to a self-cleaning litter box. The self-cleaning litter box includes a movable rake. A mechanism controlling the rake can allow for control of the forward/reverse position, the vertical position, and the rotation of the rake using a different path of travel for the forward and reverse traversals of the rake across the litter box. The controlled positioning of the rake can reduce force on the rake and other mechanical components, and more evenly distribute litter. Further, some implementations may include a dumping mechanism that involve the rake flipping so that clumps of pet waste are forcibly removed from the rake by a mechanical impact. Further implementations allow for removal/replacement of the rake.

Abstract: An animal collar includes a collar portion including a housing portion and a plurality of extension portions. Each extension portion can include an insert having a snap receiver aperture extending through the extension portion, as well as a strap receiver having a strap insertion slot and a snap fitting. The snap fitting includes a cap retention slot and one or more snap extensions positioned to engage an interior circumferential ridge of the snap receiver aperture when the snap fitting is inserted into the snap receiver aperture from the first side. The extension portion further includes a retention cap insertable into the snap receiver aperture from the second side and including at least one cap retention extension mateable with the cap retention slot and at least one cap extension positioned adjacent the one or more snap extensions.

Abstract: A pet litter box (10) includes a housing (12) having a base portion (14), a grid portion (16), and a top portion (18). The base portion has a floor (20) and a raised, peripheral ledge (22) with a vertical wall (28) and a horizontal wall (30). The pet litter box has a removable tray (40). The horizontal wall includes air vents (56). Each air vent has an upwardly extending hood (58) having a rear wall (60), two oppositely disposed end walls (62) which define an outwardly facing air outlet opening (64). Each side air outlet opening is in fluid communication with a bottom air inlet opening (66) extending through the ledge horizontal wall. The air inlet opening is in fluid communication with ambient air external of the litter box. The grid portion 16 has a generally flat floor (72) with a grid of holes (74) there through.
