  • Patent number: 6742478
    Abstract: An animal bedding material that includes a layer of substantially dry ground drywall and a layer of a substantially absorbent litter material. The ground drywall layer has a concentration of greater than 10 g/ft2 and includes ground gypsum and ground paper backing. The ground drywall constituent of the bedding material helps control odor, acts as a moisture barrier, and provides a “lift” to the waste saturated litter material, which reduces compaction and extends the useful life of the bedding material.
