Questions people ask
What does the activated carbon do?
It adsorbs odour molecules rather than masking them with perfume, which is why the listing leads with it.
Is it clumping?
Yes, and the clumps are designed to lift out cleanly.
How much is it per kilo?
£1.62: £13.99 for 8.64kg, the second-dearest here.
Does it work in a robot litter box?
The fine texture suits automatic boxes, and one reviewer uses it in one.
Why the 16 per cent three-star?
A fine, scented litter divides opinion; three stars is a preference rather than a fault.
How many ratings does it have?
24946 at the time of collection, averaging 4.3 stars, with 65 per cent five-star and 3 per cent one-star.
