Abstract
Abstract A method is provided for deodorizing and absorbing the excreta from animals, and particularly from pet animals. The method utilizes dried citrus pulp or sugar beet pulp which both coats the animal feces and absorbs urine. The residual acids and sugars left in the dried pulp serve to neutralize the odor of the excreta.
