Abstract
Abstract An improved pet litter is disclosed which has as its major ingredient the fiber fraction of alfalfa or other leafy green vegetable fibers. The new litter is prepared by squeezing chopped leafy green crops in the presence of water, ammoniated water or ammoniated serum derived from the rolled juice. The resulting pressed cake is then subjected to a low temperature drying operation followed by procedures to produce a pelletized absorbent fibrous material.
