One thing worth knowing

The "up to 7 weeks" figure is the manufacturer's own claim under conditions we haven't been given detail on, and it assumes regular scooping alongside it rather than replacing scooping altogether - a multi-cat household should expect that figure to shrink.

Why we chose it

A litter that's genuinely compostable is still the exception rather than the rule, and 700% absorption is a real number rather than marketing vagueness. Being lightweight also makes a real difference carrying it home.

Full description

Most cat litters ask you to choose between clumping well and being kind to the environment, since the two easiest materials to work with - clay and silica - are neither renewable nor especially biodegradable. A plant-based litter is one of the few options that tries to do both.

Cats Best Original is described by the manufacturer as Europe's number one plant-based cat litter, built around wood fibre technology for odour control. It has high absorption, quoted at 700% of the litter's own volume, and forms loose clumps rather than hard ones. Cat's Best say it is 100% natural, biodegradable and compostable, and that original litter can remain in the tray for up to 7 weeks before needing a full change, alongside regular scooping.

One thing worth knowing. The "up to 7 weeks" figure is the manufacturer's own claim under conditions we haven't been given detail on, and it assumes regular scooping alongside it rather than replacing scooping altogether - a multi-cat household should expect that figure to shrink.

Who it's for: owners who want a plant-based, compostable litter over a clay or silica one, and are prepared to scoop regularly to get the most out of the longer change interval.
