The cult favourite, and the litter that made Pidan a household name far beyond China. The Tofu and Bentonite blend, roughly two parts soybean to one part clay, is the brand's signature, and it arrives at No. 18 with eighty two, a litter reviewers have long crowned an odour control master.
Dust, clumping and odour each score four and a half, a trio of near perfect marks that explains the devotion it inspires. The tofu keeps the pour clean, the bentonite lends a clump that lifts like rock, and the smell control holds for days, the two materials covering each other's weaknesses with rare elegance. On the things an owner notices most, it is excellent across the board.
Tracking sits at four, the rounded grain mostly holding to the tray, and sustainability at three, which is the whole story of why this beloved litter sits where it does rather than higher. The clay content, the very thing that gives it that magnificent clump, means it is no longer fully biodegradable, and the conscience score is capped accordingly. It is the eternal trade of the mixed litter, and Pidan makes it more gracefully than almost anyone.
For the owner who wants the cleanest box this side of pure clay, with the low dust of plant and a clump that never crumbles, this is close to the ideal answer, and its enormous following is well earned. It asks only that you accept the mineral in the bag and the conscience cost that comes with it. A genuinely iconic litter, and the formula that proved a Chinese brand could lead the world on design and performance at once.
