Abstract
Abstract A system for animal excrement control which comprises the use of popcorn as a means of adsorbing and/or absorbing excrement. Animal litter so made may be employed as such, or may be impregnated with an additive such as a bactericide, an antioxidant, a deodorizer, chlorophyl, etc., dyes to give the desired color, etc. Popcorn, preferably employed in the form of small particles (i.e., comminuted) may be employed alone or in conjunction with other types of animal litter such as clays, bentonites, plastics, chlorophyl-containing litters such as dehydrated grasses, for example alfalfa, etc.
