ABSTRACT:
An odor control additive present in a litter formulation provides release of fragrance or odor masking scent only when litter is used by a cat or other animal within a litter box. The odor control additive comprises a plurality of fragrance scent microcapsules that contain fragrance scent oil. This central, fragrance scent oil is encapsulated in a microcapsule cell wall, which prevents evaporation of the fragrance scent oil and prevents overpowering of litter smell in a closed room resembling an unscented litter composition. When cat or animal enters the litter box, a load is applied to the fragrance scent microcapsules, which readily breaks releasing the fragrance contained therein. The fragrance scent microcapsule cell walls also degrade by swelling and degradation when wet by animal urine thereby releasing fragrance. Fragrance evaporating from the ruptured microcapsules provides odor control and a pleasant scent.
