Abstract: A biodegradable, clumpable cat litter made from corncob and biomass components. The animal litter is a mixture of heavy density particles and light density particles. The heavy density particles are formed of corncob grit and the light density particles are formed of sized pellets of light weight corncob components. Heavy density and light density particles are coated with mineral oil to which is adhered guar gum. The heavy density particles compose 30%-70% of the mixture and the remainder is composed of light density particles.

Abstract: A granular, biodegradable carrier made from a naturally occurring cellulose material such as corncobs, wood shavings or saw dust, rice hulls, peanut shells and pecan shells. A maximum density cellulose carrier product is produced in a wide variety of granule size ranges by the process of reducing the cellulose material to produce an intermediate pulverulent product, compressing the intermediate pulverulent product to produce pellets, shearing the pellets to produce the granular product, and classifying the granules to the desired size range. Critical control of a moisture addition to the intermediate pulverulent product before it is compressed or pelletized along with selective tempering of the pulverulent product before compression yields a maximum density pellet and a maximum density granular product.

Abstract: Compositions comprising cocontinuous interpenetrating network of a polymer of at least 50 weight percent methyl methacrylate and a polymer of ethylene and vinyl acetate, and process for preparing such compositions comprising polymerizing the major portion below 55.degree. C.
