We received a free coupon from Purina for a bag of Yesterday's News. We are used to using clumping litter and prefer "World's Best Cat Litter" over many others. This product is completely terrible. The product is messy and goes everywhere. Because it doesn't absorb or clump, the solid "pieces" even come out of the litter box and we are constantly having to pick up pieces of litter and "the other" off the floor. The product does nothing for odor control either. I do not recommend this product and luckily it was free because I wouldn't pay for another bag.
