78 out of 100 Good
The European supermarket's most recognisable clay, and a litter that lifts on the strength of a single perfect score. Catsan, a Mars Petcare brand made in Germany, brings its Ultra Plus clumping litter in at No. 28 with seventy eight, built around an exceptional clump.
Clumping is the triumph, a flawless five: the naturally sourced bentonite sets a hard, clean clump that lifts whole and resists the crumble that wastes lesser clay. Odour is excellent at four and a half, holding a box clean across the week, and dust and tracking each score a solid four, low on the pour and largely contained in the tray. On the four axes that decide a daily scoop, it is genuinely strong, and its blue and white bag is a trusted sight in homes across the continent for good reason.
Sustainability, inevitably, is the anchor, scored at two. This is mined clay, neither renewable nor biodegradable, and the conscience mark reflects the unavoidable truth of the material. It is the single reason a litter this capable on the bench sits where it does.
What you are buying is dependable European clay from one of the most established names in the business: a magnificent clump, reliable odour control, and the reassurance of a brand that has earned its place over decades. It will not please the environmentally minded, but for the owner who wants a hard clumping, widely available mineral litter from a name they recognise, Catsan Ultra Plus is a sound and proven choice. A supermarket stalwart that earns its keep on clumping alone.
