When should you remove the litter?
This type of litter does not clump. Thanks to their porous structure, crystals absorb all the liquid and volatile compounds, and store them. If the litter box is in a place with good air circulation, the substrate retains
its properties even longer. Water evaporates from the litter, and other chemicals remain in its structures. Change of the color from transparent to yellowish is a sign that litter should be replaced. Solid droppings should be removed systematically
and on a regular basis.
