Fill litterbox with 2"-3" high of litter. Scoop clumps and remove waste daily to ensure maximum freshness and odor control. Add more litter to maintain depth of 2"-3". On a weekly basis or when litter becomes saturated, empty litterbox, wash, dry and refill with fresh litter. Always wash hands thoroughly after handling the litterbox. Some cats may need to be weaned onto new litters. Gradually replace current litter with Nature's Miracle litter until complete transition occurs.
