  • A Quick Review on the World’s Best Cat Litter Brand

    The company called the World’s Best Cat Litter was founded in 1996 by scientists who had the goal of manufacturing the best clumping cat litter ever—from corn. At that time, cat owners needed a better alternative to clay, so the World’s Best Cat Litter aimed at creating a biodegradable litter that would satisfy this need.

    Today, the brand has already developed seven litter formulas. While each of these formulas has specific purposes, they are all corn-based, 100% biodegradable, and safe for you, your cats, and the environment.

    Original Series

    • Clumping: 100% whole-kernel corn
    • Multiple-Cat Clumping: optimized for odor elimination
    • Lavender-scented Multiple-cat Clumping: with added lavender oil

    Advanced Series

    • Zero Mess™: includes plant fibers
    • Zero Mess™ Pine-Scented: includes plant and wood fibers
    • Picky Cat: concentrated formula with cat attractant

    Plus Line

    • Attraction Action: focused on attracting cats to the litter box

    Reviews of Top 4 World’s Best Cat Litters

    Let’s dig into some of the most popular formulas from the World’s Best Cat Litter.

    1. World’s Best Cat Litter, Clumping Litter Formula for Multiple Cats



    This multiple-cat formula from World’s Best Cat Litter offers quick-clumping and easy-scooping, something that you would totally appreciate if you have two or more cats at home.

    The formula actually comes in two types: one has just a natural scent, while the other has an added lavender oil to help mask odors.

    What we like about this product is that it’s lightweight, so you can buy a bunch and save your back. Quite surprisingly, it’s also low in dust, so it can keep your cat’s lungs safe and healthy.

    Finally, it’s friendly to the environment, just like all the other formulas from World’s Best Cat Litter. You can even flush the litter into the toilet. Just make sure you’re not dumping everything at once.

    • Quick-clumping
    • Easy to scoop
    • Lightweight
    • Low dust
    • Flushable
    • Eco-friendly
    • The scented version may not be favorable to some cats
    • For best results, you might need to scoop more frequently

    2. World’s Best Cat Litter Attraction Action

    • 99% Dust-free
    • Odor control
    • Quick clumping
    • Easy scooping
    • Flushable

    The World’s Best Cat Litter Attraction Action variant is the very first product launched by the brand under its Plus line. The main purpose of this formula is to help you avoid “accidents” with cat poop, i.e., accidental pooping on the floor or anywhere outside the litter box.

    It draws your cats to the litter box and then makes sure they proceed with their business inside. The “secret” ingredient is a natural plant-based cat attractant combined with the concentrated power of corn.

    This litter is also optimized for a multi-cat household and is fit for all types of cats.

    Moreover, the litter’s texture is soft, which further allows your cat to have a positive experience when using the litter box.

    By the way, we have found this cat litter to be long-lasting. So, you might find this variant favorable especially if you’re looking to save money in the long run. And, like the rest, this cat litter is flushable and eco-friendly, so it shouldn’t give you too much hassle in terms of disposal.

    • Long-lasting
    • Eco-friendly
    • Flushable
    • Attraction effectively
    • May track around

    3. Zero Mess by World’s Best Advanced Cat Litter



    Part of the brand’s Advanced Series is the Zero Mess Cat Litter. It’s designed to trap liquid waste and its corresponding odors by clumping them tightly within the litter granules.

    Zero Mess uses a patented blend of whole corn kernels and plant fibers so that the resulting litter becomes super-absorbent. Its 100% natural formula uses concentrated granules so that you can use less litter and get even better performance.

    Only clump-forming plant ingredients are included in this litter’s formula, so it has no silica content. As a result, the Zero Mess litter is 99% dust-free.

    Aside from preventing odors, the quick-clumping action of Zero Mess provides powerful odor control. Plus, it prevents the litter from sticking to your cat’s litter box. Thus, this litter is perfect for heavy-duty use. It’s even excellent for a multi-cat household.

    Since it’s septic-safe, the Zero Mess litter is totally flushable and eco-friendly.

    • Quick-clumping
    • No silica dust
    • 99% dust-free
    • Flushable and septic-safe
    • Eco-friendly
    • Can track around the house

    4. World’s Best Picky Cat Advanced Multiple Cat Clumping Cat Litter



    If you have senior cats, little kittens, newly adopted felines, or even fussy Toms, then you might need a litter that encourages them to use the litter box properly. That’s the goal of the World’s Best Picky Cat Advanced Multi-Cat Clumping Litter.

    The granules of this litter work together to create tighter and smaller clumps compared to other formulas. This makes the odor stay locked inside the litter. With this formulation, your kitties would feel more comfortable while doing their business.

    This Picky Cat formula also keeps the standard of being eco-friendly since it’s made from corn and natural plant fibers that were all sustainably grown. It has no added chemicals, as well.

    Finally, it’s 99% dust-free. So, it should be able to keep your seniors and little ones free from dust allergies.

    • Tight-clumping
    • No added chemicals
    • 99% dust-free
    • Eco-friendly
    • Superb odor-control
    • A little more expensive
    • Can track on the floor

    World’s Best Cat Litter Brand Vs. Other Cat Litter Brands?

    Price – 4/5

    Prices fluctuate, but at the moment, the World’s Best Cat Litter isn’t really that pricey if you compare it to other brands that use corn as the primary ingredient. For instance, Nature’s Miracle Premium Clumping Corn Cob Litter is currently slightly at the higher end of the budget compared to the original World’s Best Cat Litter formula.

    Currently, the formulas under the Advanced Series are the most expensive products of this brand.

    Clumping Action – 5/5

    All of the World’s Best Cat Litter products can form tight and hard clumps, thanks to the process of compressing corn materials and concentrating them into the litter that you now see.

    So far, the World’s Best Cat Litter Clumping Formula (the original formula) forms the most reliable, tight, and hard clumps that don’t easily crumble.  In my experience, it has worked even better than the clumping clay litter that I once used. Many other users love the original formula as well.

    Odor Control – 4/5

    World’s Best Cat Litter only uses natural ingredients such as corn, plant, and wood fibers in its formulas and has no special ingredient for odor control, except for its lavender-infused product. Of the seven formulas, the World’s Best Lavender-Scented Multi-Cat Clumping Litter is the most effective at controlling odors with its added lavender scent.

    Still, it’s not necessarily the best among all other brands of litter in terms of getting rid of odors. For instance, the Ever Clean Extra Strength Cat Litter has better odor-controlling agents such as activated carbon.

    Dust/Tracking – 3.5/5

    The World’s Best Cat Litter uses concentrated corn to ensure that the resulting product is 99% dust-free, like Ökocat Litter. But since the granules are tiny, you can still expect some tracks.

    Among all the formulas made by this brand, the World’s Best Lavender-Scented Multi-Cat Clumping Litter is, surprisingly, also the most effective formula against dust and tracking (according to our experience).

    Easy to Scoop – 5/5

    Scooping isn’t a problem with World’s Best Cat Litter because of its effective clumping action. You can easily take the large clumps using any litter scoop, and the remaining clean granules would simply fall back into the litter.


    Overall, is the World’s Best Cat Litter worth it?

    I’m glad to say that Yes, the World’s Best Cat Litter can live up to being really the world’s best in many ways.In fact, many cat owners have already been using it for over 10 years now. They found the product to be dependable in terms of tight-clumping and easy scooping. Plus, all the formulas are biodegradable, septic-safe, and flushable, which is pretty convenient.

    Just be aware that since the World’s Best Cat Litter formulas are corn-based (with some formulas adding other plant materials), they can attract insects. You just have to do your part of maintaining the litter box clean and covered, as much as you can.

    Finally, some formulas are scented (like the lavender-infused one). You may or may not like how it turns out to smell, but that’s just one option among many. And, with the seven variants this brand currently has, I’m pretty confident that you’d be able to find one that matches your kitty’s preference and yours.
