Abstract: To provide an animal litter from seed hulls such as sunflower hulls, seed hulls having a fatty acid content between 1 percent to 15 percent by weight, at least 40 percent of the fatty acid being unsaturated fatty acid and being between 50 to 95 percent by weight of hulls, is formed as pellets without substantial added binder. The seed hulls serve the function of aiding in pellet forming to avoid the need of substantial added binder as well as aiding in deodorizing. One appropriate additional deodorizing material that may be an added ingredient is alfalfa. The pellets are preferably formed to sizes between 3/64 to 1 inch in diameter but the size is related to the heating and cooling of the pelletizer.
