have used this brand for several years, but supply across the board has been spotty. But it would be my first choice if available. Reasons: imho the size of the pellets is just right (similar to Nurture Pro Tofu) i.e. not that small so doesn't track very easily, and not as dusty as some of the other tofu litter i have used. Smell is ok and not over-powering. Clumps well and quickly (doesn't form soft clumps at the bottom like some other tofu litter). My main issue is its costliness.
