Abstract
The formation of the odor associated with cat litter boxes is prevented by inhibiting the bacterial action on cat urine. A sorbent pad structure is positioned between a protective screening, capable of withstanding the clawing action of a cat, and a moisture impermeable liner. The cat urine is transferred directly from overlying litter particles, through a cat claw resistant screen into a sorbtive-desiccant member of fibers and having high surface area and high urine sorbency. The urine disperses quickly from fiber to fiber in the sorbtive-desiccant member. The moisture impermeable sheet prevents urine from leaving the side of the sorbtive-desiccant member opposite the screen. The screen and the fibers of the sorbtive-desiccant member provide for aeration, thus inhibiting the growth and bacterial action of bacteria as well as the evaporation of the urine from the sorbtive-desiccant member. Consequently, the bacteria die or become dormant thereby preventing significant odor formation.
