Abstract An animal litter having improved odor control properties comprising a major amount of an absorptive litter material and a minor amount of an odor control agent derived from sagebrush. The absorptive material may be an absorptive mineral, a fibrous organic material or a chlorophyll-containing grass. The odor control agent is ground sagebrush or sagebrush oil. The animal litter may contain from about 0.005%-10% by weight of the odor control agent.
