  • Patent number: 6895896
    Abstract: The present invention is directed to enhancing the odor control of a manufactured composite cat litter granule by including as a component thereof and entrapped therein an effective odor controlling amount of small size silica gel particles. The manufactured granule preferably includes a clay component but may rather include any number of absorbent filler materials such as paper mill sludge, recycled paper, corn cob renderings, rice or peanut hulls, or other organic plant materials, so long as the materials can be agglomerated into a cat litter granules and entrap small size silica gel particles.

  • Patent number: 6659042
    Abstract: An economical process that combines bentonite, or similar clays, that form a clump when in contact with cat urine, with waste cellulosic fibrous materials, preferably paper mill sludge, to form a light weight scoopable (clumping) cat litter product. In the process, paper mill cellulose waste is combined with bentonite clay (preferably sodium bentonite) in a mixing auger in varying percentages depending upon the desired end weight of the finished product, transferred to a secondary rotating drum mixer, then to a rotating drum dryer, and from the dryer to a screening process. The finished product is a granule weighing between 20 lbs./cubic foot and 50 lbs./cubic foot. The granule is highly absorbent and capable of forming a distinct clump that can be separated from the surrounding granules without falling apart. A unique characteristic of the process is the combination of heavy clay particles with light weight cellulose particles to form a new composite particle.
