  • Patent number: 4437430
    Abstract: A receptacle for holding cat litter material is secured in a toilet bowl in such a fashion that it can be easily used by cats. The apparatus includes a substantial flange for providing stability and a rim overlapping tab to secure the receptacle to the front of the toilet bowl. Holes are provided in the bottom of the receptacle to drain liquid. The size and location of the receptacle is such that it covers only approximately 1/6 of the total opening of the bowl. Therefore the apparatus can be used with cats at will and without assistance and does not have to be removed in order for the bowl to be used by humans. A cat can be trained to use the apparatus with progressively smaller amounts of litter material until the cat uses the apparatus without any litter material at all. At that point it may be possible to remove the apparatus so that the cat relieves itself directly into the toilet bowl.
