Composite particles suitable for use as a clumping animal litter according to one embodiment include an absorbent material, and a superabsorbent polymer coupled to the absorbent material, where a ratio of rates of absorption of the superabsorbent polymer and absorbent material is at least about 1:1. Composite particles suitable for use as a clumping animal litter according to another embodiment include an absorbent material and a superabsorbent polymer coupled to the absorbent material, where the superabsorbent polymer has a greater Jenkins osmotic potential than the absorbent material. |
