Abstract
A low tracking clumping litter is provided that has larger non-clumping litter particles with particle sizes sufficiently large enough relative to smaller clumping litter particles thereby disposing substantially all the smaller particles of litter in a litter box below the surface of the litter packing them into in voids between adjacent non-clumping particles. This reduces tracking because the surface is made up of the larger particles, which are not readily picked up by a cat, minimizing the number of smaller more readily tracked particles on top because they are packed in the voids. This causes urine to rapidly wet and swell the clumping particles trapping the urine forming the clump on top. The litter has a tracking effectiveness of less than 100 particles/in2 and clumping particles preferably composed of extrusion modified starch-based water-soluble binder produce shed-resistant clumps having clump retention rates preferably greater than 97%.
