84 out of 100 Very good
The Winner's quieter sibling, and one of the more unusual materials on the list. Tofu Cat Litter Australia builds this litter not from soy but from oat, a renewable grain rarely seen in the tray, and it arrives at No. 15 with eighty four on an even, honest card crowned by a faultless conscience.
Dust, clumping, odour and tracking each score a solid four. There is no single flourish here and, just as importantly, no single failing: the oat pours cleanly, sets a respectable clump, controls smell adequately, and largely stays in the box. It is a litter defined by balance rather than brilliance, the sort that simply works without drawing attention to itself.
Sustainability is where it climbs to the top tier, a perfect five. Oat is renewable and biodegradable, the litter flushes in small amounts, and it carries the same locally made, carefully sourced credentials that lift the brand's flagship to the summit of the list. On conscience, it gives away nothing to anything here.
It sits below its Original sibling because the enzyme magic and the perfect tracking of that litter are not repeated, and the four across the performance axes marks it as very good rather than exceptional. But that undersells the appeal. For the owner who prizes a fully renewable, faultlessly green litter and wants a gentle, low fuss everyday experience without the premium of the flagship, the Oat is a genuinely likeable answer. A novel grain, handled with the same integrity as the rest of the range, and a reminder that this Australian maker treats sustainability as a starting point rather than a slogan.
