ABSTRACT:
The invention provides a method of increasing the sorption capacity of smectite clays which exhibit osmotic swelling such as montmorillonite clays having predominately sodium as the exchangeable cation. The invention further provides a clumping cat litter having excellent cohesiveness comprising certain mixtures of a clay which exhibits osmotic swelling, a cellulosic material, and optionally a density controlling material, the clay, the cellulose material, and the density controlling material having certain particle size distributions, and the cat litter having a bulk density in the range from about 0.54 to about 0.96 g/cc and a sorption capacity greater than about 1.0 cc/g, wherein the concentration of the smectite clay is such that upon wetting the litter the cohesiveness of the lump of wetted litter is sufficient to allow its removal from a litter box, and wherein the concentration of the smectite clay is insufficient to prevent the lump of wetted litter from disintegrating in water over time.
