World's Best Cat Litter: A Review

Kitty litter has come a long way with the introduction of scoopable cat litter and all-natural, plant-based varieties. Dust-free cat litter is also a revolutionary advancement! There are many kinds to choose from, which can be overwhelming. There are a number of factors to consider when making this choice. To some extent, your cat has just as much say in the matter as you do. Kitty litter certainly isn't one-size-fits-all.

In this article, I will review World’s Best Cat Litter and delve into the pros and cons of the product.

My Qualifications

I have worked in shelters, been a pet sitter for at least 100 cats, and most importantly, been a cat owner my entire life . so I've had a lot of experience with kitty litter! Here's how all the unsavory time I've spent cleaning out cat boxes is worth it. I have a lot of experience and recommendations to share in my cat litter reviews. Naturally, I'm the official “scooper" in my house—I've only had a brief sabbatical from that duty while I was pregnant due to the risk of Toxoplasmosis.


  • If you care about the environment, like I do, this is the best cat litter choice. They are flushable, biodegradable, and organic.
  • It doesn’t have any strong perfume smells. Some cats really don’t like a lot of artificial odors emanating from their litter.
  • It’s a totally dust-free cat litter. Really, it is! There are a lot of cat litter brands that boast being 99% dust-free, but it still seems to kick up an awful lot of unhealthy dust.
  • It does do a good job of clumping. However, you really need to scoop the clump quickly or it dries out and crumbles.
  • It lasts a long time and a little goes a long way.
  • It’s not heavy like many of the clay litters. You won’t have to break your back or enlist the help of a neighbor to bring it in and pour it.


  • The negative part of World’s Best Cat Litter’s light weight comes if you have a cat who likes to perch on the edge of the litter box while doing her duty. I've discovered many cat boxes overturned as a result, with a disastrous aftermath.
  • It’s average to below average in the odor control department. I’ve found I really need to frequently clean it out to keep the odor under control.
  • It’s pretty spendy, but I do have to admit it lasts a long time.
  • It's not as easy to find as the more commercial brands of cat litter.

Ingredients: What to Look and Look out For

World’s Best Cat Litter is among the new generation of clumping, dust-free cat litter, and certainly the least environmentally-offensive of all. Toxic litters are made from a variety of ingredients: corn, corncob, cornhusks, wheat by-products, wheatgrass, beet pulp, oat hulls, and kenaf. World’s Best Cat Litter is made from corn—whole kernel corn, in fact.

I would stay away from wheat-grass and beet pulp litters, as they don't control odor very well. Kenaf is what's used to make tree-free paper and is related to cotton. I've had the privilege of using many of these and have been quite pleased with their clumping ability. Like the crystal litters, these don't weigh very much, which is a definite advantage for some.

Questions to Ask When Purchasing Cat Litter

Obviously, cat litter prices vary according to type, brand, and where it's purchased. You will need to comparison shop by asking yourself these questions.

  • How well will it work with your cat pan? Some litters won't work well with automatic litter boxes.
  • Is it biodegradable? Clay-based kitty litter is not biodegradable and has a huge impact on the environment. Sadly, more than 2 million tons of cat litter is dumped into our landfills yearly. Most of the litter isn't biodegradable.
  • Is it flushable? Some of the new plant-based litters can be flushed right down your toilet. Not only is it convenient, but it is also environmentally friendly.
  • How well does it control odor? Not all litters are equally as efficient at controlling odor. Clumping litters have become the most popular since actually removing the offending smell is one of the best odor control methods. However, there are alternatives as I will discuss below.
  • Is it a dust-free cat litter? Many commercial brand cat litters are quite dusty, posing health issues for both owners and cats alike. Look for ones that say dust free cat litter.
  • Is it full of chemicals and perfumes? Many kitty litters have unhealthy amounts of additives in them. In addition to the health concerns, a lot of cats simply do not like the strong smell emanating from their litter boxes. They might choose another, quite unpleasant place to defecate.
  • Is the texture one that's pleasant for your cat? Cats are funny about their paws. Many don't like the new crystal cat litters. They find them irritating on their sensitive paws. One of my cats would have nothing to do with the crystal litter, she looked like she was walking on hot coals in the pan.

Voted UP! Good review on WBCL. I've used it for several years. We tried the pine litter, and one of my cats developed a urinary tract infection. So, back to World's Best. I have to say that, for us, the odor control is very good, but we always remove soiled litter and feces daily. One drawback is that it doesn't last nearly as long as the bag says it could, though. We don't live near a large pet chain store, so we have to buy it at our local grocery store at 9.50 a bag (small size). The reason why we continue to pay this crazy price is because it really is dust-free. I'd love to find a dust-free alternative, but for now, it's totally worth the price.

Hi homesteadbound, thanks for coming by. They really can be picky about their litter, can't they? And what is it about them liking to use beds as their own little potties? Anyway, good to see you.

Cindy Murdoch from Texas on January 01, 2012:

You are so right about the decision being ours and the cats. We have changed litter before and watched a cat jump out quicker than they jumped in because of the difference in consistency. She chose to use our bed instead. Needless to say, we learned our lesson quickly!

Elsie Nelson (author) from Pacific Northwest, USA on January 07, 2011:

yenajeon, so sorry you're dealing with cat litter allergies. There are lots of perfumes and dusts in many commercial cat litters. I'd try one of the plant-based litters (like Integrity or S'Wheat or World's Best Cat Litter). The pine alternative is also a good one, although I think they fail in terms of odor control (scooping litters are better in this regard). Good luck and let me know how it turns out!

Yena Williams from California on January 07, 2011:

Thanks for the help, I'm currently looking for a non-allergenic cat litter. Perhaps one made from pine or newspaper. Any advice?

Overall, Is World’s Best Cat Litter A Good Choice?

We are happy to report that World’s Best Cat Litter lives up to its name. There are many things to love about this brand, not least the affordable price. The fact that this brand uses only natural, compressed corn materials means that every formula is lightweight, highly absorbent, and flushable. This makes World’s Best one of the easiest, most convenient cat litter brands for cat owners.

One thing to be mindful of with this brand is that some formulas are scented. We found the lavender scent to be very light and pleasant, but some customers found that the scent mixed unpleasantly with litter box odors. If you’re sensitive to smells, you may want to stick to unscented formulas.

All of World’s Best Cat Litter’s formulas are safe for kittens over 8 weeks of age and for adult and senior cats. One final concern is the fact that it is made from natural materials so it may attract insects. You can avoid this issue by tightly sealing the bag and by not placing your litter box outside in humid areas.

What is the Best Cat Litter in 2020?

The search for the best cat litter can’t start without going over a small educational stepping stone. First, you’ll need to know what types of cat litter are available on the market and what perks they offer. Then, you can slowly figure out what kind you and your cat needs. Different types can account for different needs either from you or your cat, so pay attention to these when shopping for litter.

  1. Odor Control – If you have a busy schedule, or aren’t that keen on cleaning the litter box multiple times a day, an odor-control litter might be the best option for you. It absorbs and reduces the smell from the box, leaving your house and apartment odor-free.
  2. Clumping – Clumping cat litter is designed for easy cleaning. Simply put, you won’t have to empty the entire litter box every time you want to clean the kitty’s bathroom. Most of these products contain bentonite, which allows litter to clump after the cat urinates. You can then quickly remove the clumps and leave the litter box clean.
  3. Scented – Some litters come in a variety of smells, like lavender or pine. While it’s not strong enough for you to smell it around the house, it can effectively mask other scents in the litter.
  4. Unscented – Unscented cat litter is fairly straightforward: litter that doesn’t smell. Cats have a notoriously delicate scent, and it’s possible for some kitties to dislike scented litter, which is why owners can opt for the unscented version.
  5. Multi-Cat – Packages advertised as multi-cat generally have stronger features. For instance, if it’s an odor control litter, it will be stronger than single-cat litter regarding how much odor it can absorb. You can use it if you have multiple cats in your households, though it’s not mandatory.
  6. Lightweight – Lightweight litter is almost 50% lighter than regular litter, perfect for owners with multiple cats. So, if you have two or three cats, you can stock up on litter, as the lightweight version is easier to carry.
  7. Non-Clumping – Non-clumping litter is one of the first types of cat litter ever to make it in the household. Some packages can also come with various scents, though you should know that with a non-clumping litter you’ll have to keep a close eye on the box. Left for too long, urine can pool at the bottom of the box, giving an unpleasant smell.
  8. Flushable – Flushable litter is, perhaps, the most environmentally-friendly option form the list. It’s completely biodegradable, generally made from corn, wood, or wheat. And, the best part about it is that you can clean the box just by flushing everything down the toilet.

7 Best Cat Litters of 2021, According to Pet Pros

These picks have superior odor control and minimal tracking.

Let's face it: One of the best parts of having a cat, aside from the endless unconditional love they bring, is not having to take them outside to do their business. However, litter boxes (even self-cleaning boxes) come with their own set of problems ranging from smell, cleanup, and well, finicky cats (we love you, too.) With that being said, not all litters are created equal, and choosing the wrong one is no hissing matter.

Our home care experts and engineers in the Good Housekeeping Institute Pet Lab test everything needed to keep pets and owners happy, from the best food to pet cameras. To find the best cat litter, we take into account things like absorbency, odor control, tracking, and clumping ability. Our favorite litters were easy to scoop, helped control odors, and didn't track little particles all over. Here are the best cat litters that the Good Housekeeping Institute recommends from top-performing brands and online reviewer favorites:

  • Best Overall Cat Litter:Dr. Elsey's Premium Clumping Cat Litter
  • Best Value Cat Litter: Special Kitty Scoopable Cat Litter
  • Best Odor Control Cat Litter:Purina Tidy Cats Pure Nature Cat Litter
  • Best Clumping Cat Litter:World's Best Cat Litter
  • Best Plant-Based Cat Litter:ökocat Natural Wood Clumping Cat Litter
  • Best Flushable Cat Litter:sWheat Scoop Natural Clumping Wheat Cat Litter
  • Best Cat Litter for Multiple Cats:Arm & Hammer Cloud Control Cat Litter
  • Best Crystal Cat Litter:Fresh Step Non-Clumping Crystal Cat Litter

This clay-based litter is uniquely formulated, combining non-tracking granules with a medium grain, so litter stays in the box where it belongs. It also has an excellent clumping ability that prevents moisture from reaching the bottom of the box for easy cleanup. Reviewers love the low dust factor and great odor control, making it a great litter for multiple cat households as well. And cats seem to love it, too!

  • Chunky granules for low tracking
  • Reviewers noted superior odor control
  • Unscented

Great for multiple cats, reviewers love the light, fresh scent that helps with odor control. We found that the tight clumping formula makes scooping your cat's box a breeze. We also love that it comes with an easy-pour handle — and that you can get 20 pounds of this clay-based cat litter for under $6!

Not only do we love that this litter is comprised of alternative ingredients, including pine, corn, and cedar, but it is also highly absorbent, allowing for easy clean-ups. And did we mention that this litter is formulated to fight even the toughest odors, leaving your home smelling fresh and clean? Our reviewers love that bags come in various sizes, making it easy to carry and pour.

  • Made with pine, corn, and cedar shavings
  • Lightweight bags available
  • Reviewers commented on the fresh, natural scent

A runner-up to our top overall pick, World's Best Cat Litter is indeed one of the best. Although a bit pricier than some, our pros love that it is unscented and made with corn cob particles instead of clay. This clay alternative option clumps easily to make cleanups a breeze and the manufacturer claims that it is flushable and septic-safe, which was confirmed in our Lab tests.

With a soft texture similar to that of clay, this litter is easy on paws and cats seem to like the fresh, natural scent reminiscent of the great outdoors. Made entirely from wood grains and particles, ökocat offers a clay alternative with reviewers raving about its low tracking, great clumping, and super absorbency. The wood fibers are meant to prevent enzymes from bonding with liquid to stop the creation of odors. We love that it is lightweight and has no artificial fragrance or dyes, making this perfect for the green-loving household.

Made of wheat and plant extracts to help eliminate odors, sWheat scoop premium cat litter claims to clump faster and firmer for easy scooping, designed for cats who are sensitive to dust, perfumes, and dyes. Made from renewable plant sources, the manufacturer states that it is designed to be flushed, which we found to be true in testing.

If you have two or more cats in your home, then this is the litter for you. The odor control is long-lasting and can be scooped and cleaned without tremendous clouds of dust. We loved that the litter has fine, sand-like clay granules that form tight clumps and won't stick to the bottom of a dirty litter box, perfect for easy clean-ups.

Ditch the clay and switch to gel silica crystals, which the manufacturer claims is more absorbent and better odor control than traditional clay litters. This litter locks in odor and absorbs moisture on contact, plus it's scented and smells fresh and clean. It works with any traditional litter box and self-cleaning ones. While we haven't tested it in the Lab, reviewers love that it has virtually no tracking.

Not only are there different types of litter, there are also different materials that litter is made of. It will likely take some trial and error to find the right litter for you and your cat. According to American Veterinary Medical Association (AMVA), when analyzing all the different types of cat litter, you should identify what you consider to the most important factors (though ultimately, your cat may be the decision-maker in the end!):

  • Material:Most litters are made of bentonite clay, since it is inexpensive and can produce solid clumps to make scooping easier. However there are a bunch of new alternatives including gel crystals, pine, wheat, tofu, corn, and paper that are milled, sawed, ground, or cut into fine granules or chunky particles. Those without clay or silica dust are generally viewed as more eco-friendly, and the all-natural alternatives come with big advantages like being flushable, offer less dust for allergic cats, and less tracking around the house. Litters come in various scents and grain sizes, and cats seem to like the texture the best as it is closest to soil.
  • Absorbency: This is the ability for the material to hold the urine. Brands make claims that crystal litter is the most absorbent kind of litter available because it is made from sodium silicate sand that is processed with oxygen and water. The result is a bead-like crystal with tiny pores allowing for more liquids to sink in. In our road tests, we found that crystal litter does absorb more liquid, allowing for less clean-up and longer-lasting.
  • Odor control: Some litters include baking soda or activated charcoal that help keep urine and fecal odors at bay. However, these odor-masking scents can be a turnoff to your cat, so it may take a bit of trial and error to find the odor control that works for both you and your kitty.
  • Clumping ability: Clumping litter tends to help minimize messes and make it easier for you to scoop for easy clean-up because it is mixed with bentonite. Non-clumping is usually cheaper, but it's hard to scoop urine or fecal matter without changing the whole pan.
  • Dust levels: This isn’t just important to keep your floors and furniture dust-free, but also important for keeping yours and your cat’s lungs clean. Clumping cat litter tends to produce the most dust in general, but this may take a bit of trial and error.
  • Tracking: The goal is for your cat’s litter to stay in their box and not get tracked around the house. Keep in mind that clay litters tend to track more than some other materials and larger particles tend to track less than small ones. A mat outside the litter box also helps remove particles from kitty's paws.
