Using this Tidy Cats litter is a breeze. First, simply pour the litter into your cat's litter box. For best odor - control results, fill the box to a depth of about 3 - 4 inches. Scoop out solid waste and clumped urine daily to keep the box clean and fresh. Every 2 weeks, replace all the litter to maintain its ammonia - blocking power. When handling the litter, be careful as it might still generate a little dust, so pour it slowly. Store the remaining litter in a cool, dry place to keep it in good condition. If you have multiple cats, you may need to change the litter more frequently depending on their usage.
