How We Tested The Litter:

• We spent a few weeks testing the cat litters on several cats.
• We did not receive these product in exchange for a favorable review, they were purchased with our own money.

Brand Overview

The World’s Best Cat Litter company was founded in 1996, when a group of scientists set out with the goal of creating the best clumping cat litter on the market. In doing so, they discovered a revolutionary process that transformed natural ingredients like dried corn into a cat litter that delivered concentrated odor- and liquid-absorbing power for a cleaner, fresher litter box.

The brand’s claim to fame is the fact that World’s Best Cat Litter offers cat owners the potential of having a cleaner litter box with less mess and less waste. Compressed corn is a highly absorbent material that forms tight clumps, making the task of scooping the litter box quicker and easier than ever. Plus, hard clumps means less waste, as clean litter simply falls back into the litter box. The clumps themselves can be safely flushed down the toilet for disposal.

World’s Best Cat Litter is so confident in their products, that they offer a money-back guarantee within 90 days of purchase.

What Kinds of Litter Does the Brand Offer?

The World’s Best Cat Litter brand currently offers seven different formulas.

The Original Series including three recipes, all made from 100% natural compressed corn. The Plus Series includes one formula formulated to attract cats to the litter box. The Advanced Series includes three formulas designed to solve specific problems.

The three formulas we’re reviewing here are the clumping formulas included in the Original Series.

Top 3 Cat Litters Reviewed

#1

World’s Best Cat Litter Scoopable Multiple Cat Clumping Formula

When you have more than one cat, litter box odors can add up quickly. This clumping formula is uniquely designed for multi-cat households to reduce litter box odor and to make scooping easy. It features compressed corn for high absorbency, forming tight clumps that trap odor and are easy to scoop. This dust-free formula is environmentally-friendly, flushable and natural.

This multi-cat formula is incredibly lightweight which makes it easy to transport, and it is much less dusty than traditional clay litter. In testing, we found it to be a little dusty when first pouring fresh litter into the box, but the dust settled very quickly and wasn’t an issue from that point on. The litter formed tight, hard clumps which made the box easy to scoop and it resulted in very little waste.

Category Rating Price 3/5 Clumping Action 5/5 Odor Control 3/5 Dust/Mess 4/5 Scent 3/5 Easy to Scoop 5/5 Overall Rating 3.5/5

Pros:

• Excellent clumping action, easy to scoop.
• Naturally absorbent compressed corn materials absorb liquid on contact.
• Subtle natural scent, no added fragrance.
• Very low dust and relatively low tracking compared to clay litters.

Cons:

• May develop a foul odor when exposed to a large amount of urine.
• Offers moderate odor control, requires frequent scooping for better results.

This litter comes in 7, 14, and 28-pound bags. Because the litter is made from compressed corn rather than clay, it is lightweight compared to most traditional cat litters.

#2

World’s Best Cat Litter Clumping Formula

Made from natural compressed corn materials, this clumping cat litter is free from silica dust so you and your cat can breathe easy. It forms tight, hard clumps for easy scooping, and it is biodegradable and flushable for easy disposal. This cat litter is eco-friendly and unscented, making it an excellent choice for single cat and multi-cat households.

Like the other formulas tested, this litter produced a little dust when first pouring but it settled quickly and was not a long-lasting issue. The litter did take on an unpleasant odor when exposed to large volumes of urine, but frequent scooping was sufficient to control litter box odor. The litter itself had a very slight scent to it but nothing strong enough to irritate cats with sensitive noses.

Category Rating Price 3/5 Clumping Action 5/5 Odor Control 3/5 Dust/Mess 4/5 Scent 3/5 Easy to Scoop 5/5 Overall Rating 3.5/5

Pros:

• Forms hard, tight clumps on contact with urine and feces.
• Very low dust (no silica dust) compared to clay litters.
• Eco-friendly and all-natural, clumps are flushable for easy disposal.

Cons:

• May take on an unpleasant odor when exposed to lots of liquids.
• Lightweight corn kernels may track more than heavier cat litter.
• Offers moderate odor control, needs frequent scooping for better control.

This litter comes in 7, 14, and 28-pound bags. Because the litter is made from compressed corn rather than clay, it is also lightweight, just like the previous product reviewed above.

#3

World’s Best Cat Litter Lavender Scented Multiple Cat Clumping Formula

This scented formula offers the same hard-clumping benefits as the other two formulas, with the addition of a pleasant lavender scent. Generally speaking, World’s Best Cat Litter offers average odor control – when exposed to a significant amount of urine it can retain some odor. In this case, the lavender scent helps to mask that odor, keeping the litter box smelling fresher for longer.

In addition to its pleasant scent, this cat litter is eco-friendly and flushable. It forms hard clumps on contact with both solid and liquid waste, relying on the benefit of the fresh lavender scent to control odors for longer than average. It is very low in dust and low-tracking as well, helping you keep your house clean. Plus, it is formulated for multiple cat households.

Category Rating Price 3/5 Clumping Action 5/5 Odor Control 4/5 Dust/Mess 5/5 Scent 4/5 Easy to Scoop 5/5 Overall Rating 4/5

Pros:

• Absorbs liquid on contact, forming hard clumps.
• Clumps are easy to scoop and flushable for disposal.
• Very low dust and non-tracking.
• Pleasant lavender scent helps cover litter box odors.

Cons:

• Litter may take on an unpleasant odor when exposed to a significant amount of urine.
• Some cats find the lavender scent unpleasant or too strong.

This litter comes in 7, 14, and 28-pound bags. Because the litter is made from compressed corn rather than clay, it is lightweight compared to most traditional cat litters.

What Do Customers Think of World’s Best Cat Litter?

Pet owners are a picky bunch, to be sure. When it comes to products like cat litter, there are certain basic requirements that must be met in order to satisfy a cat owner. For the most part, World’s Best Cat Litter meets or exceeds these requirements, and customers are largely satisfied with the brand.

This being said, every customer’s experience is unique, and there are both good and bad reviews for the brand online. Keep reading to see a positive and negative customer review for each of the three cat litter formulas featured above:

Positive Customer Reviews for World’s Best Cat Litter

“I love this cat litter. I made the switch after discovering that most traditional litters contain silica, which when inhaled over time, can cause lung diseases including cancer. I thought, what do I have to lose? With a name like World’s Best Cat Litter, maybe it really was good stuff! Well, it sure is. This litter is literally just ground up dried corn. That is it. It is magical, clumps very tightly, and doesn’t have little bits breaking off and crumbling away. My cats had zero issues adjusting to their new litter.” – CaitlinCatLady, reviewing World’s Best Scoopable Multiple Cat Clumping Formula

“Highly recommend the World’s Best green bag formula! I’ve used this product for 12 years with two cats. We are sensitive to smells and wanted to easily clean the litter box. A friend recommended this – it’s so easy to flush feces daily (or hourly)! Clumps well too. I tried the multi-cat formula once but seemed to have a perfume/odor. This green bag formula doesn’t have odors and works great.” -Julia, reviewing World’s Best Clumping Formula

“Happy customer! This stuff is awesome! My 2 cats with 3 litter boxes means a lot of scooping. This is the easiest, cleanest litter to scoop. Pee clumps quickly, but doesn’t stick to the box, just to the waste! Even if your cat, like mine, pees at the very edge of the box, you’ll scoop the clump without any scraping or chipping away to dislodge it from the box. It lifts right out.” – Cleaner, reviewing World’s Best Lavender Scented Multiple Cat Clumping Formula

Negative Customer Reviews for World’s Best Cat Litter

“My cat is a Maine Coon. He is huge and makes a lot of urine. He was too big for this litter… The urinated litter sticks to the bottom of the pan like goo. He is so big he also tracked it around the bathroom. I used to clean the box and floor every day or two… I don’t advise this for an adult cat whose urine comes out like a race horse. But a small cat is okay.”  – Pippinsmom, reviewing World’s Best Scoopable Multiple Cat Clumping Formula

“This litter works very well right out of the bag. It forms tight clumps and traps odors. I never smelled anything! However, a few weeks of just topping off the litter when I scooped as needed, I noticed the litter overall was turning into a fine dust. This dust ends up everywhere plus the litter tracks far and wide. I always assume clumping litter will track, and I will say this is not nearly as bad as clay litter.” – CatOwner, reviewing World’s Best Clumping Formula

“My first impression is the lavender smell is not great. Second, it does not hide smells it more mixes with the smells and creates an even worse smell. I was using basic clay litter from my local store before, it was way cheaper, and I never smelled the litter box. With this litter, I smell it all through the house. However, it is really easy to clean! It clumps really well.” – Imalady, reviewing World’s Best Lavender Scented Multiple Cat Clumping Formula

How Much Does World’s Best Cat Litter Cost?

Many cat litters made from natural materials are more expensive than traditional clay litters, but that is not the case with World’s Best Cat Litter.

This brand is similarly priced to traditional litters, but you actually get more for your money due to the concentrated power of naturally absorbent corn materials. A small bag of World’s Best Cat Litter lasts one cat 30 days or longer because it is low-waste and would normally cost between $1.1-$1.2 per pound.

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.

Where Is World’s Best Cat Litter Sold?

World’s Best Cat Litter is sold online and in pet stores. You can find it for sale from online retailers like Chewy and Amazon as well as big box stores like Walmart and Target, and local and national pet stores such as PetSmart and Petco.

It’s easy to get confused and even overwhelmed when considering all the different types and brands of cat litter that are available today. How do you choose which one to use?

All cat litters fit into one of the several major categories, and each one has advantages and disadvantages when compared to others. This article will help you to narrow down your choices, but you are still likely to be faced with some trial and error before settling on the one that works best for you. Actually, you need to choose the litter that works best for you and your cat, as our feline friends can be picky about litter, and if they won’t use, it… well, you probably know the rest.

Traditional Clay Cat Litter

These are the litters that look like sand, and in fact for a long time sand (and/or dirt) was what was used for cat litter. But clay is a lot more absorbent, and in the late 1940s, industrial absorbents were repackaged and clay cat litters became available commercially. With numerous other better performing choices, clay litters are not that popular any more, comprising only about 3% of sales at A Pet’s Life.

Advantages:

• It’s cheap. Clay litters cost the least.

Disadvantages:

• It’s dusty. And that’s silica dust, a known carcinogen when inhaled.
• It’s easily tracked. It sticks to cat paws quite easily, and gets tracked around the house.
• It’s heavy. You’ll be lugging it at least twice, once before and once after it’s used, and it’s like carrying a bag of sand.
• It’s not easy to dispose of. You can’t flush it or compost it, so you are likely left with putting it in the garbage.
• It’s not long lasting. You’ll use quite a lot, as it needs to be replaced often because of its limited ability to absorb liquid and to suppress odour. For this reason, many people put the litter box in the basement or garage, where the smell can be ignored longer.
• It’s environmentally unfriendly. Tons and tons of clay litters end up in landfills every year, and the extraction of clay for litters usually involves some form of strip mining.

All this doesn’t make traditional clay litters sound so terrific, well, except for that cost thing. Additives such as baking soda and odour maskers, either already in the bag or as an extra that you sprinkle in yourself, are sometimes used to help with odour control.

A traditional clay litter available at A Pet’s Life is Jonny Cat.

Clumping Clay Cat Litter

In the the 1950s, someone got the bright idea that adding some form of bentonite clay to a traditional clay litter would be a big improvement. Bentonite, which in litters is nearly always either sodium bentonite or calcium bentonite, is a type of clay that forms from the weathering of volcanic ash. The advantage of bentonite in cat litters is that it will absorb several times its dry weight in liquid, and in doing so it expands as much as 15 times its original volume and at the same time forms clumps that can be scooped out without removing the rest of the litter. This is a terrific functional improvement over traditional clay litter. Clumping clay litters are about 13% of sales at A Pet’s Life.

Advantages:

• It’s easy to scoop. Using a sifting litter scoop, you can remove both feces and the urine clumps, leaving the rest of the litter in the box.
• It’s economical. Although periodically all the litter has to be removed, the same quantity of clumping clay litter will last longer than traditional clay litter.
• It’s not so smelly. Since regular scooping removes both feces and urine, it’s easier to live with it in close proximity.

Disadvantages:

• It’s potentially unhealthy, maybe even dangerous. There’s plenty of controversy about this, but some believe that inhaling that absorbing and swelling bentonite dust is a bad idea, and your cat will certainly inhale some of it.
• It’s dusty. Like other clay litters, that’s silica dust, a known carcinogen when inhaled.
• It’s easily tracked. It sticks to cat paws easily, and gets tracked around the house.
• It’s heavy. It’s just as heavy as traditional clay litter, although you will use less of it.
• It’s not easy to dispose of. You certainly can’t flush it, imagine that clumping and swelling going on in your plumbing! The only disposal option is the garbage.
• It’s environmentally unfriendly. Again, it’s extracted using some form of strip mining.

Clumping clay litters available at A Pet’s Life include Cattitudes, and Dr Elsey’s Precious Cat.

Silica Gel Cat Litter

Silica gel litter is relatively new, and is sometimes referred to as crystal litter. It’s actually a granular form of sodium silicate, a substance with an incredible ability to absorb liquids, so it’s no surprise someone decided to market it as cat litter. It also has many industrial and commercial uses, such as those little packets you find in vitamin bottles. In use, you have to scoop out the feces every day, but urine is absorbed and just seems to vanish. It doesn’t, of course, it is just soaked up, and eventually the litter’s ability to absorb any more is gone. Then it’s time for a complete change. Some people find that a 2 kg bag will last for a month for one cat. Silica gel litters have gained much of a following, with only 2% of sales at A Pet’s Life.

Advantages:

• It’s economical. If a small bag lasts your single cat for a month, it might be the lowest cost alternative.
• It’s lightweight. No more lugging those big, heavy bags.
• It’s minimal work. Scooping feces and stirring the crystals are all that is needed, at least until it needs a complete change.
• It’s relatively dust free. Especially when compared most other types of litter.

Disadvantages:

• It’s fussy. It gives no warning when it’s “used up”. Usually, the only indication is the puddle of urine in the bottom of the litter pan. Then it quickly gets really stinky. Some silica gel litters have a portion of the granules change colour as they get saturated to indicate when it needs changing.
• It’s often not accepted by cats. While some cats are happy to use it, many refuse to do so.
• It’s sometimes messy. Those little round beads of silica gel can get rolling on the floor and go a long way. If your cat is a digger, and throws litter around, this might get really annoying. Look for the silica gel litters that are odd shaped, although there is a downside to these: some of the edges can be sharp and don’t feel very nice to step on, for you or your cat. If your litter box is in a high traffic area such as the bathroom or laundry room, you’re bound to step on one from time to time!

A silica gel litter available at A Pet’s Life is Clear Choice.

Biodegradable Litter

In recent years, a wide range and variety of plant-derived litters have become available. These biodegradable litters can be further divided into two types: pelleted or granular.

Pelleted Biodegradable Cat Litter

Made from either wood or recycled newspaper, pelleted litter has an incredible ability to absorb liquids, and in doing so will crumble into an easily removable form. Sawdust that is a by-product of wood processing industries or recycled newsprint is formed under very high pressure into pellets, which are then thoroughly dried. Wood pellets absorb urine so well that they are used extensively as bedding in horse stalls. Feces must be scooped from the cat litter box regularly, along with the pellets that become urine soaked and crumbly, leaving the remaining pellets behind. Pelleted biodegradable litters are about 25% of sales at A Pet’s Life.

Advantages:

• It’s relatively dust free. And whatever dust there is relatively benign.
• It’s environmentally friendly. Made from either recycled newspaper or wood processing by-products
• It’s easy to dispose of. The crumbled pellets can be flushed or composted (but not the feces, of course!)
• It’s non-tracking. Well, the pellets don’t track easily, although the crumbled bits do.

Disadvantages:

• It’s often rejected by cats. Some fussy cats just don’t seem to like the feel of the pellets on their paws.

Pelleted biodegradable litters available at A Pet’s Life include Feline Pine, Crown Animal Bedding, Stall Dry, Yesterday’s News, and Good Mews.

Granular Biodegradable Cat Litter

There are plenty of choices in this category: wheat, corn, barley, and pine, and it’s worth trying some different types to find the best one for you and your cat. These litters are made from the by-products of the human and animal food, as well as the wood processing industries, and so use materials that might otherwise be waste. Clumping properties come from the starch or cellulose components and odour is controlled by the natural enzymes and proteins in the litter. Granular biodegradable litters are far and away the most popular, currently having about 57% of sales at A Pet’s Life.

Advantages:

• It’s environmentally friendly. They are biodegradable and made from renewable resources.
• It’s easy to dispose of. These litters are easily flushed or composted (but not the feces, of course!)
• It’s lighter than traditional clay litters.
• It’s fairly long lasting. With proper daily maintenance, a bag will last twice as long as an equivalent size bag of clay litter.

Disadvantages:

• It’s easily tracked. It sticks to cat paws quite easily, and gets tracked around the house.
• It’s somewhat dusty. Some users find these litters to be dusty, although at least it’s not silica dust.
• It doesn’t capture odours as well as clumping clay litters. Daily, if not twice daily scooping is necessary for odour control.
• Its natural odour may be offensive. Some people find the smell of the wheat, corn, pine, etc to be disagreeable.

Granular biodegradable litters available at A Pet’s Life include Swheat Scoop,World’s Best, Feline Fresh, and Rainforest.

In Summary

The bottom line is that there is no such thing as a perfect cat litter. It would really be great if there were, but it just isn’t so. They all have their advantages and their disadvantages. Some of these are inconveniences for cat owners and some are negatives for the cat. It really makes sense to choose the litter that is the most accepted by your cat, given the range of problems that can arise otherwise. It will likely take some trial and error to find the right litter for you and your cat. If you’re not sure where to start, talk to any of the A Pet’s Life staff for good advice and go from there. Good luck!
