I have always bought Scoop Away because it is clumpable and packaged in boxes. Because changing litter types can cause a cat to pee and poop outside the box, I do not want to stop buying it until Patricia dies. However, I have decided to look for a different type of litter for my next kitten because Scoop Away is very messy and I can't go in the laundry room barefoot. Is there another clumpable litter that never tracks away from the litterbox?
