Guardian Angel pine pellet cat litter is achieved through an extrusion process that heats the wood fiber to levels of pasteurization. Oils in the wood are removed to reduce allergens. Concerns of molds, toxins and other contaminants found in unprocessed fibers, woods, corn, wheat and clay are eliminated. Softened fiber will instantly absorb, trapping odors and moisture. Wicks moisture out of solids to reduce odors and risk of contamination. Pine litter pellets are perfect for cat litter boxes, bird cages, guinea pig and reptile habitats. As a cage and habitat bedding, pine litter pellet will reduce odor through its natural ability to absorb quickly and retain odor until it is removed through daily cleaning. Comes in 25-pounds bag.
