Described herein is a toilet seat capable of being coupled to an existing toilet bowl enabling the toilet to be used by animals. Further, the toilet seat can be used in training an animal to use a toilet as opposed to going outside or using a litter box. The toilet seat has a platform for the animal to rest upon as well as a number of inserts configured to help with training the animal to use the toilet.

A portable toilet litter bowl for cats that fits human toilets of all conventional sizes, may be alternately placed in a functional position on flat surfaces, that provides an uncomplicated, space-saving, secure, environmentally friendly cat toilet apparatus. The litter bowl is comprised of a plastic injection molded unitized structure including a flat u-shaped horizontal platform member that provides a comfortable area on which cats may jump, stand and rest their front paws, a central basin extending downwardly from said platform into a conventional human toilet bowl in which flushable cat litter is placed and cats urinate and defecate, a basin opening with a sliding cover system that provides a simple, sanitary method for expelling soiled litter and containing clean litter, a semi-oval shaped internal wall extending upwardly on the back and sides of said platform to prevent cat litter from spilling onto the floor, a semi-oval shaped external wall/base extending downwardly from the top of said internal wall with a base perimeter flange that keeps said toilet litter bowl steady and secure on a conventional human toilet as well as on flat surfaces, and a pawprint shaped handgrip opening adjacent each side therein to provide a simple, quick method for moving said toilet litter bowl on and off a conventional human toilet. Said litter bowl is designed for regular use, not cat toilet training.

A potty training device includes: a support body providing an internal space where a pet is able to enter and defecate; and an inducer receptor disposed in the internal space of the support body and providing a first inducer receiving space in which a defecation inducer is contained, wherein the support body includes: a support plate supporting the inducer receptor on an upper surface thereof and having a defecation hole through which excrement of the pet passes; and a wall protruding upward from the upper surface of the support plate to accommodate the inducer receptor and having an entrance formed on one side such that the pet is able to enter and exit the support body, and wherein the entrance is disposed near the defecation hole.

An indoor pet toilet system has an elevated platform having a vertical wall extension along the rear, a drain opening through the top surface of the platform, a water source connection, a sewer drain connection, and a motion activated and timer controlled flushing mechanism in fluid communication with a water source.

A feces and urine disposal device for cats includes a support structure having parallel, vertically extending wall members, a bottom chamber, and an elevated relief area between the opposing wall members and above the bottom chamber. The relief area includes a pair of longitudinal channels disposed in spaced, parallel relation to one another and an open longitudinal gap between the channels and communicating with the bottom chamber. In use, a cat stands in the relief area with the left paws in one channel and the right paws in the opposite channel so that the cat is straddling the gap. When the cat relieves itself, feces and urine pass through the gap and into a removable trough positioned in the bottom chamber or directly into a toilet bowl. Cat litter or another odor absorbing or containing substance can be placed in the trough, as well as the relief area.
