What I really like about Cat Spot Litter is that it is all natural. There is NO dust or odor from the litter itself. I appreciate that because I am mildly allergic to most litters and my cat :) Because it is natural (I have the non-clumping) I can flush the solids in the toilet. What I don't like about Cat Spot Litter is, just like all litters, it tracks everywhere! Because it is so light weight I find it throughout most of my house and on the furniture. I have a Cat Spot Litter box, which I like, and I have put small throw rugs outside of the box, but still there is litter almost everywhere. It does control odor pretty well as long as you mix it up really well. I don't feel it lasts as long as they predict before I feel the need to empty it completely. It probably goes about 10-12 days. I have one neutered male cat.
