Pidan turns to the cassava root, and the result is one of the most complete plant litters on the list. At No. 7 with ninety two, this is the brand's cassava formula, and it pairs the dust virtues of plant material with a clump that very nearly rivals clay.
Dust is a flawless five, the cassava pouring clean, and clumping is a perfect five too, the great trick of this litter: cassava starch sets hard and fast, lifting in one dense piece with none of the softness that holds pure tofu a half step back. To score full marks on both dust and clumping is rare air, achieved by only a handful of litters here.
Odour is excellent at four and a half, controlled cleanly with only the faintest gap before the perfect mark, and sustainability sits high at the same four and a half, a renewable, biodegradable root crop that flushes in small amounts. The single softer figure is tracking at four, where the cassava grain travels a little more than the very best, the one axis keeping this from the summit.
What you get is the Pidan hallmark applied to a different material: considered grain, intelligent absorption, and a finish that feels engineered rather than poured. For the owner who wants the hardest clump a plant litter can offer without surrendering the clean air and clear conscience of the category, this is close to the ideal answer. A superb, renewable, hard clumping litter, and a reminder that cassava may be the most quietly capable material in the room.
