Rank #1 in Best Cat Litter 2026: Why the Litre Tells You Nothing
Catsan Hygiene Plus Cat Litter White, 20L Non-Clumping
Price and rating as shown on Amazon when we collected them. Both change.
Catsan Hygiene Plus is the best-selling product in Amazon's entire pet supplies category: 33,577 ratings at 4.6 stars for £15.00, a 20-litre bag that weighs 9.5kg.
It takes first place on evidence — 81 per cent five-star and 3 per cent one-star across the deepest sample in this ranking — and it publishes both numbers, litres and kilos, which is what lets you work out that it costs £1.58 per kilo of litter against £0.83 for the cheapest bag here.

Questions people ask
How much is it per kilo?
£1.58: £15.00 for a 9.5kg bag. That is the number to compare between litters, not the litre.
Is it clumping?
No. Non-clumping litter absorbs into the granule, so you empty the tray rather than scooping clumps.
Why is the litre misleading?
Because a litre of this litter weighs 0.48kg while a litre of the heaviest here weighs 0.84kg. The same 10 litres can be nearly twice the litter.
Does it smell?
It is unscented and uses mineral odour control; one reviewer calls it the best on the market.
Is it worth 90 per cent more than the cheapest?
That depends on your cat: this is the one with 33,577 ratings, and the cheapest per kilo has 10,537.
How many ratings does it have?
33577 at the time of collection, averaging 4.6 stars, with 81 per cent five-star and 3 per cent one-star.
