A lightweight disposable kitty litter box comprises a container which forms a closed receptacle (110) and fresh kitty litter (20) which is enclosed within the closed receptacle (122). The kitty litter (20) comprises a resilient paper product having a density between 0,017 g/cm<3> and 0,17 g/cm<3> (.01 and .10 ounces per cubic inch). The container is convertible between a closed condition in which it forms said closed receptacle (110) and an open condition in which it forms an open receptacle (122). To supply a kitty litter box for a cat, the container is converted into the open condition to form the open receptacle to thereby allow the cat access to the fresh kitty litter (20). The cat may then interact with the fresh kitty litter (20) until it reaches a sanitarily unacceptable state. The sanitarily uncceptable kitty litter is then enclosed in the closed container by converting the container into the closed condition. The container and the sanitarily unacceptable kitty litter enclosed therein may then be disposed as a unit.
