We were looking for a change in our natural litter, and decided to try this one, as I have enjoyed the odour reduction that pine can give in the past. It was really good for the fist couple of weeks. Given that I did not like Worlds Best multi cat, I was surprised. After about 2 weeks the litter turned to dust. Every time I would clean, I'd end up with it floating around me. Clumping and smell control stayed though.
