“I am so happy I changed! I felt like I was going through so much litter and this seems to help. The smell is less noticable. If I kept up on daily cleaning it would be non existent. It doesn't "track", however a few small pieces from time to time escape. ***I needed to put a layer of the cats old style litter on top of the new style for them to use it at first. After the first box, they did not need their old litter.”
