Advanced Zero Mess Cat Litter by World's Best Cat Litter – 12 lb Review

I find the normal world's best cat litter excellent. It is better and very close to the dust. Major advantage; the cat likes it.

We've used the best black in the world in the busiest cat box. It really seems better than the usual best in the world, which really is the best in the world.

Our family has used four of the best types of cat litter in the world and they all work for us. We thought "Zero Mess" was the best of its kind, but it's very hard to find in large retail stores. Many thanks to Rescue Pet Supply for the delivery.

It's definitely a lot less messy and the filler didn't leave marks nearly as often as usual...but it was a lot LESS effective at removing odors. I'm going back to the regular (red) Worlds Best Packs because the promised "Zero Chaos" perk seems to have replaced the Odor Eliminator.

The best thing about this product is that it doesn't absorb any odors. Which makes it useless in my opinion. I was able to get a refund and am happy with the customer service. It's hard to rate anything else because I was so focused on the lack of odor absorption. If you're not concerned about odor absorption, you'll probably like this product more than I do.
