  • Cat litter box
    Patent number: 5590623
    Abstract: A cat litter box has a solid bottom, vertical sides and a top with an opening to admit a cat. The height of the vertical sides is such that a cat can reach the top with its forepaws by standing on its hindlegs. The box is low enough that a cat would have easy access to the box, yet is deep enough to prevent the escape of litter or excreta from the box during use by a cat.
