Yes ! There are three, Depth of crystal litter in litter box, Scooping, and Stirring.
Depth of crystal litter in cat box: The ideal depth to fill your cat’s litterbox is two inches (8 cm). This is the depth required for the odor-defeating technology to function optimally.
Scooping: Most users scoop feces daily, and discard in toilet or garbage. Do NOT flush any large amount of litter. If a few crystals cling to the solid waste that is scooped, this is harmless. You will need a scoop with wide slots, so the crystals fall through the slots.
Stirring: After scooping, stir the crystals about the litterbox. Most of the urine is directed at the center. If you don’t stir, the crystals around the perimeter are virtually unused and the crystals in the center are saturated. This reduces the useful life of the product.
