Abstract
A waterproof receptacle for use in the disposal of animal waste products. The litter receptacle contains a layer of porous expanded shale. The porous shale has a porisity of at least 10% by volume for reducing bulk density of the porous shale and an ability to absorb liquid waste upwardly. Advantageously, the porous structure allows a portion of the liquid to flow to the bottom of the receptacle for subsequent upward absorption. Most advantageously, a screen size of at least +50 mesh (300 microns) is maintained to limit dusting. Optionally, 5 to 25% by weight ammonia absorbing zeolite may be added for odor control.
