A sensor on the animal's tail that signals the onset of elimination or presence of waste, may be coupled to the station's electronic system, or to a speaker near the animal's ear for producing unpleasant sounds to discourage elimination outside the station. Electronic systems are used to reward the animal after its elimination in the station.

Abstract: The advantage of this toilet for cats relative to conventional models consists of the fact that the toilet automatically cleans itself after each use and is again automatically supplied with fresh cat litter.Annoying odors are extensively eliminated by that the used cat litter is immediately removed into a separately mounted, air tight waste container equipped with a replaceable bag, by a slide.This satisfies both the hygienic requirements of contemporary household pet maintenance and the cleanliness needs of cats.The probelm is resolved by that a slide is located in the cat toilet facility, which moves the used cat litter into an automatically opening and closing waste container and that subsequently fresh cat litter is distributed over the bottom by an automatic refill device. To prevent access to the toilet facility during the cleaning process, the inlet is closed by a sliding door.
