Best Litter I have ever used

I have 4 cats, and this is the best litter I have ever used. I have had cats for many years and have used a lot of different litter brands. It is a little pricey, but not with the 40-pound size. It works wonderfully. I have a litter box in my home office, and this litter is amazing at controlling the odor. Please continue to manufacture and sell this litter, as I have never used anything better in the decades I have owned cats

Pretty Good

[This review was collected as part of a promotion.] ​ I like Arm & Hammer cat litter in general, so I'm always excited to try a new variety. This was about as good as the rest of their line, and I would say it does somewhat cut down on how much they track it out of the litterbox. (Although mine like to fling and dig, so no help there!) Unfortunately I was not a huge fan of the clumping. It didn't clump as well as usual and stayed pretty tacky/gluey when scooped. Overall pretty good, not the greatest. #sponsored I am receiving points toward rewards in the Kitty Krew Community for writing this review. All opinions are my own.
