ABSTRACT:
A method of making animal litter consisting of grinding peanut hulls into a size that will allow the ground hulls to pass through a one-sixteenth to a one-half inch sieve. Mixing the ground hulls with a ground vegetable product such as alfalfa, broom grass, or a like product containing chlorophyl to give the mixture not less than one percent chlorophyl content. The mixture is subjected to a steam bath to moisten and soften the hulls and the added product which are then forced through a die to form the mixture into small pellets. The moisture in the pellets is reduced by heating as they pass through the die thereby removing at least eighty percent of the moisture.
