Cat Litter Review -- World's Best Clumping Formula

We have eight litter boxes set up in our home.  Two are on the main level; six are in the basement.

Currently we use World’s Best Clumping Formula cat litter in five of the boxes.  It's packaged in a green and black bag.  We like it for the following reasons:

Great clumping, even near the sides of the box
If you’re gonna scoop, you’ll want the clumps to remain intact and not fall apart as you perform your duty.  Compared with the two other clumping brands that we’ve tried (Tidy Cats and Naturally Fresh), World’s Best seems to form the most robust clumps.

Low cost
I’ve seen World’s Best priced as low as $1 per lb.  (In fact, we use our pet supplier’s “Auto Ship” service and get additional discount and free shipping.)  But what really matters is the cost per volume.  The 7lb bag is all you’ll need to fill one empty litter box.  It’s generally more expensive than Tidy Cats, but cheaper than Naturally Fresh.

Ubiquitous – even our grocery store carries it
It’s convenient if your go-to brand of cat litter is available at the local “Brick & Mortar” stores you regularly shop at.  Occasionally I’ll need an extra bag, or I might walk by and notice that it’s marked down in price.  While Tidy Cats also is widely available, Naturally Fresh is a bit harder to find.

Compostable
Because it’s made from corn, World’s Best will eventually decompose, so it can be composted.  It does take quite a long time for this, though, perhaps more than six months.  I suppose the same can be said for Naturally Fresh, although I’ve never tried it.  Tidy Cat is clay and is not considered compostable.


What we don’t like:

Dust
World’s Best claims to be 99% dust free.  What does that mean, exactly?  My guess is that if you put 100 units in a box, then over a period of time 1 unit of it will become airborne while 99 units remain in the box.  What’s the period of time?  The lifetime of 1 month, perhaps?  What are the units?  Weight?  Volume?  Nevertheless, it emits less dust than Tidy Cats and, I think, Naturally Fresh, which claims to be “virtually dust-free.”  This is the main reason we switched away from Tidy Cats and then from Naturally Fresh.  I’m still looking for a product with less of a by product of dust.

Slow to drain
We have one very Prolific Peer (PP).  His output is so voluminous that he wets himself because his stream splashes up from the puddle he produces.  This is the main reason we’ve started to swap out the clumping litter with non-clumping.  The non-clumping litter (Feline Pine) drains very quickly, so our PP cat stays dry.

Punctured Packaging
Occasionally we’ll get a bag that’s punctured.  So far, we’ve not had any brand new cat litter that’s been exposed to water.  But a couple of bags have leaked a small amount of product.  It’s always pretty obvious when you get a punctured bag – it tends to look as though it has air in it rather than “vacuum-packed.”

Corn
I’m not a fan of corn.  I can’t eat too much of it because it gives me joint pain.  I wonder if just breathing in its dust can bother me.  And what effect does it have on the cats?  We have one cat who needs anti-seizure medication and another that seems to have upper respiratory problems and eye discharge.  I’m hoping that they’ll improve as we transition to more non-clumping litter.

Slow Flow Through Scoop
I ended up buying a new scoop, one with a larger grid pattern, because this litter doesn't flow well through a typical scoop.  The granules are irregularly shaped, unlike the spherical granules that make up the clay litter I was accustomed to.
