Abstract
A litter box which cleams itself automatically, and separates the soiled litter from the clean litter, storing the soiled litter in a receptacle and replacing the consumed litter by clean reserve litter. The litter box is formed from a sieve (1) configured as an endless web, a continous transport belt (8) for taking up litter to be recycled. The belt (8) circulates in a housing (5, 7, 9, 11). The litter box optionally includes a system (6, 15, 16, 18) comprising a bin bag facilitating the filling of the receptacle 21 even in a substantially horizontal positon. The litter box is useful with eats and other animals, particularly pets, farm animals or wild animals in captivity.
