Abstract
Cat litter is formed from ground corncob granules, a clumping agent such as guar gum, and an odor control agent such as soyaethyl morpholinium ethosulfate. A water solution of the odor control agent is sprayed onto corncob granules. Thereafter, the clumping agent is slowly mixed in (without forming clumps), and excess water is evaporated off. The odor control agent is applied in a substantially uniform and adherent manner, without materially comprising absorbency or causing significant premature clumping.
Claims1
A method of producing an animal litter, comprising:
- providing at least 90% of corncob particles by weight;
- providing at least 0.1% of clumping agent by weight;
- and providing at least 0.1% of an odor control agent by weight;
- obtaining a water solution of the odor control agent, wherein the odor control agent is soyaethyl morpholinium ethosulfate;
- then spraying the water solution of the odor control agent onto the corncob particles;
- then mixing a result of the spraying with the clumping agent to create a moist litter, wherein the clumping agent is applied at a slow enough rate of application so as to create a moist litter that is, prior to an animal leaving waste on the litter, free of clumps;
- and
- then permitting at least some water in the moist litter to evaporate from the moist litter while leaving the odor control agent adhering to the corncob particles;
- thereby achieving a well distributed odor control agent without exhausting the function of the clumping agent in the animal litter.
