I think it's fabulous that the folks who started this company thought to take scrap wood that was going to go to a landfill, and make something useful with it, which would also reduce the need for bentonite mining. DOUBLE WIN for the environment! My kitties really like it. I'm currently doing half regular litter and half Catalyst as I wean them into it. Even my one kitty, who is persnickety as hell about the litter box, has not peed once outside the box, even if I miss a day cleaning it. I love it! And the wood smell of the unscented litter is most pleasant. The boys approve!
