Zeolite pellets must be used as a filler only for special dual-level cat trays. Pellets are poured onto the grate - the upper level. It is necessary to pour 2 Liters (approximately 1.6 kg) of pellets. The layer should be 2-3 centimeters. A special underpad with superabsorbent is inserted into the lower level. Use high-quality underpad; otherwise, they will have to be changed much more often. Cats solid “business” must be removed from the tray with a special spatula. Pellets that are soiled or stuck to excrement must be discarded. Please note that pellets do not dissolve in water, so they should not be thrown into the toilet. Add pellets as needed. And completely replace them with new ones after 30 days or sooner if there is an unpleasant odor. For loose stools, remove dirty cat litter. If the toilet is very dirty, please wash it and use it after drying. The Superabsorbent underpad must be changed as it fills up - usually 7 days (for cats up to 8 kg). In the middle of the underpad change period, it can be turned 180 degrees to distribute urine over the diaper evenly, as usually, cats pee in the same spot in the litter box.
