82 out of 100 Very good
A young Chinese brand with a designer's eye, and a cassava litter that earns its place on substance. Petshy, a fresh name from the same competitive domestic market that produced Pidan and Xucuihua, brings its cassava formula in at No. 19 with eighty two, a clean and capable plant litter with a single soft spot.
Dust and clumping each score four and a half, the heart of its appeal: the cassava root pours with almost no haze and sets a firm, fast clump that lifts in one piece, the characteristic strength of the material. Odour control is strong at four, clean and reliable if a half step short of the very best, and sustainability sits at the same four, the renewable, biodegradable root flushing in small amounts.
The one figure that holds it back is tracking, marked at three and a half, where the light cassava grain wanders from the box a little more freely than the denser pellets above it. It is the familiar tax of a fine plant litter, and the only real blemish on an otherwise tidy card.
What Petshy demonstrates is how deep the Chinese plant litter bench now runs. This is not a market leader or a household name, simply a well made cassava litter from a thoughtful young brand, and it comfortably out scores far better known clays elsewhere on this list. For the owner drawn to the clean pour and clear conscience of cassava, who is willing to keep a mat by the tray, it is a quietly rewarding choice. A promising newcomer, and further evidence that the centre of gravity in plant litter has shifted east.
