Made with a natural plant ingredient for even more outstanding odor control, this multiple cat clumping litter is easy to scoop and proven flushable for simple cleanup! Having more than one cat shouldn’t mean you have more to worry about it. Your cats deserve the best clumping cat litter.Directions: 1. TRANSITION SLOWLY: Start with only a third of World's Best Cat Litter added to a clean box of your current litter. Then, once your cat is more familiar with it, change to two-thirds. After that, use only World's Best Cat Litter. 2. PICK A GOOD LOCATION: Provide at least one litter box per cat. Place the box in a quiet place that can be easily accessed and is away from the cat's food and water dishes. 3. KEEP IT CLEAN: For best results, scoop clumps daily and maintain a depth of 2-3 inches of World's Best Cat Litter.
