Abstract

Animal litter having up to a sixty percent reduction in bulk density can be produced by combining flat-shaped cellulosic materials and sodium bentonite clay. Not only is the resulting litter lighter, but it also maintains a high clump strength as compared to clay-based animal litters that contain greater than ninety percent by weight sodium bentonite clay.

Claims (4)

1. A method of making composite particles having a cellulosic material component and a sodium bentonite component comprising:

providing flat-shaped cellulosic particles having a mean particle size ranging from 0.2-3 mm;

providing powdered sodium bentonite particles having a mean particle size less than 0.25 mm, wherein the ratio of cellulosic material to sodium bentonite is in the range of 1:4 to 4:1;

using a high shear agglomeration process to mix the cellulosic particles and the sodium bentonite particles to form composite particles having a mean particle size in the range of 0.4-4 mm.
