<p>The invention provides a composition suitable for use as an animal litter comprising a first component having a density less than that of liquid and a second component having a density of at least 5 lb/ft3 (80 mg/cm3) greater than the first component. The invention is based upon the discovery that adding liquid such as urine to a composition having two components with significant differences in density, one of which is less than the density of the liquid, will result in the component with the lesser density floating to the top of the liquid while the component with the greater density will segregate below the component with the lesser density.</p> |
