Abstract: A particulate urea product having improved anticaking and nonfriable properties and which is useful for either direct application to the soil or as an intermediate product for the subsequent incorporation with other fertilizer materials into solid bulk blends. The product consists of an admixture of urea and a finely divided mineral filler selected from the group consisting of diatomaceous, sodium bentonite, calcium bentonite, kaolin, zeolite and ball clay and is in either granular or prill form.

Abstract: An animal litter capable of agglomerating in the presence of animal urine so that the wetted litter can readily be separated and removed from unwetted litter, comprises clay granules which have, exposed on their surfaces, a layer or pregelatinized, cationic starch which is confined to the surfaces of the granules; the starch comprising between 0.2% and 2% of the weight of the litter. The layer of starch is effective to cause agglomeration of adjacent granules when wetted, but is such that the agglomerated granules will readily disagglomerate when placed in water, to allow flushability.
