Abstract
Most conventional animal litters develop malodors fairly quickly. An animal litter in accordance with the present invention selectively releases an odor masking component in response to agitation of the litter by an animal. The animal litter comprises absorbant particles having microcapsules affixed to exterior surfaces of at least some of the absorbant particles. The microcapsules encapsulate the odor masking component, which is released when the microcapsules are ruptured.
