1. In a clean cat litter box, put a garbage bag on it, put a pet urine pad on it, and put a layer of crystal cat litter about 4 cm (1.5 inches) thick.

2. If there are multiple cats, it is recommended to shorten the cat litter replacement cycle proportionally, rather than putting too much cat litter in the litter box.

3.1.5KG/3.8L/bag of cat litter: one cat, one month; two cats, about 15 days; three cats, about 10 days.

4. When the cat litter in the cat litter box is saturated, wrap the garbage bag in the pet urine pad and clean it with the crystal cat litter. Replace with new litter bags, pet changing pads and crystal cat litter.
