I have been surprised by the ability of this litter to trap odors. I have layered with my old clumping litter to break in the cat and it seems to have worked quite well. I just followed the recommendations on the bag. Cat does just fine. I clean it quickly every day and one bag has lasted 3 weeks already without having to be completely changed. It is less tracking that clay litter for sure and I think smells better than some of the corn litter I have been trying lately. I am going to keep trying it and find the limits on the bags no biggie since I order frequently from the website anyways.
