Abstract
Abstract A system for animal excrement control which comprises the use of plastics such as foamed plastics capable 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., surfactants to make the plastic more adsorbing and/or absorbing, etc., dyes to give the desired color, etc. The foamed plastic, preferably employed in the form of small particles, may be employed alone or in conjunction with other types of animal litter such as clays, bentonites, chlorophylcontaining litters such as dehydrated grasses, for example alfalfa, etc.
