  • Patent number: 6216634
    Abstract: A grain-based animal litter comprising discrete plural particles of a grain-based substrate, which particles tend to agglomerate into clumps when wetted. The litter of the invention absorbs liquids such as animal excretions, and substantially reduces the odor thereof. Preferably, the-substrate is a grain germ; more preferably, the substrate is a corn germ; most preferably, the substrate is washed, spent grain germ. In accordance with a preferred embodiment of the invention, the grain germ is provided in the form of discrete plural granules, each of which granules includes a cohesiveness agent in an amount sufficient to enhance the cohesiveness of the granule.
