The bag answers its own question twice

World's Best say one 8lb bag lasts one cat or kitten "38+ days" in one line and "60+ days when used with one cat" in another, in the same description, and neither figure comes with a tray size or a scooping routine attached. Take the lower one as your planning figure. The flushable claim arrives with limits printed alongside it too: their own instruction is a maximum of one or two clumps at a time, only into a well-maintained system, and to check with a plumber if you are unsure — which is not the same as a litter you can pour away.

Why we chose it

Corn answers the dust question rather than the smell one, and that is why it is on the shelf — nothing with silica in it can honestly make the same claim. Start with the unscented original, because a perfume is the thing a cat is most likely to object to. This is also the smaller bag, which matters when litter is the one purchase in the house a cat can veto outright.

Full description

Nobody ever notices a cat litter doing its job. The only day it registers is the day the bag runs out, which makes how long one lasts the figure most worth knowing and the one hardest to pin down — a fact this particular bag demonstrates rather well, since its own description answers the question twice and gets two different answers.

What is not in dispute is the material. This is made from whole-kernel maize with no added chemicals, which is a different proposition from clay or crystal litter in one specific way: corn carries no silica dust, so the 99% dust free claim comes from what the raw material is rather than from anything done to it afterwards. The granule is fine and clumps quickly, so waste is trapped before it sticks to the bottom of the tray, and this is the Original Unscented, with no perfume added on top.

Who it's for: owners wanting off clay and mineral litters, households where dust is a problem for the cat or the person scooping, and anyone whose cat has objected to a scented litter and needs the plain version.

Common questions

What is it made from?

Whole-kernel maize, with no added chemicals. That is also where the dust claim comes from — corn is naturally free of silica dust.

Is it scented?

No. This is the Original Unscented.

Can it really go down the toilet?

World's Best describe it as flushable and septic safe, but their own instruction is a maximum of one or two clumps at a time, only into a well-maintained system, and to check with a qualified plumber if you are unsure about yours. If you have any doubt, bin it.

Does it clump properly?

It is a quick-clumping litter with a fine granule, and the maker's claim is that the corn absorbs waste before it sticks to the tray, which is what makes scooping easier.

How big is the bag?

3.63kg, which is the 8lb size.
