摘要：
Animal litters and methods of making and using such litters are disclosed herein. The animal litters comprise (a) a plurality of absorbent particles comprising (i) a non-swelling particle and (ii) a clumping material coated on the non-swelling particle and (b) a plurality of one or more filler particles that are not associated with the absorbent particles. The filler particles provide additional functionality to the litters, e.g., controlling odor, absorbing moisture, releasing fragrance, controlling microorganisms, controlling dust, reducing density, reducing weight, and combinations thereof. The litters are made by producing the absorbent particles using conventional means and combining the absorbent particles with one or more filler particles that impart the desired characteristic to the litters.
