A pet litter composed of limestone particles in the size range of 0.0001 mm to 4.75 mm which clump readily when contacted by pet urine, particularly cat urine. The particle size is typically between 0.6 mm and 1.18 mm. In addition, a thickener that may be digested by cats may be added to the limestone base to enhance the clumping properties of the litter. The composition can range from 80% limestone particles:20% thickener to 98% limestone particle:2% thickener. A typical composition is 98% limestone particles and 2% thickener.
