Detailed Expert Reviews of Top 6 Clumping Cat Litters

Another option for the best clumping cat litter is clay, which contains a large number of minerals. Cats that eat litter may be trying to make up for a mineral deficiency in their body. A clay-based litter is a good option but be sure to read the label to ensure that it is safe for your cat.

#1. Arm & Hammer Platinum Slide Easy Clean-Up Clumping Cat Litter

Arm & Hammer Platinum Slide Easy Clean-Up Clumping Cat Litter

Buy it on Amazon

Arm & Hammer has always maintained a strong catalog with excellent products. This version comes with a focused improvement – the ability to slide the clumps aside when cleaning. It is the best option when the ability to clump is your top priority.

This is among the fastest litters I’ve tested. It clumped almost instantaneously, leaving no urine behind. Additionally, I noticed no loose pieces that could create a lingering smell.

All of this product power really made a night-and-day difference when it was time to clean up the box for your cat. Most of the time, all I needed to do was “slide” the clumps out, and they would fall out. This cat litter cut down on sticking and required little scrubbing.

It maintained this performance when I changed to a box with a different shape. This scented one comes with a light flowery smell. And you can see it in action right on the first day. This cat litter worked well with my pets. Normally I can smell the smell of their box several feet away. But I couldn’t really notice anything with the Arm & Hammer Slide until I was standing near it.

This cat litter is not a dust-free product, but it comes really close to that. There was little dust when I poured it out, but not enough to bother me. I was just as impressed when scooping as well. There were no clouds of dust to choke out my lungs like many other products.

Likewise, I was satisfied by the fact that this cat litter tracked very little. It was a big bonus because my cats didn’t create any big mess when climbing in and out of the box. Their paws were amazingly clean after using this product. The granules didn’t follow them and left trails all over the place.

Consider this cat litter if you’re a busy person and don’t want to spend much time getting rid of litter from your furniture and bedding all the time. The best part of this premium product is that it doesn’t make customers think much about their budget. Pricing-wise, it is comparable to most clumping clay cat litter on the market.

The big 37 lb bag option is also a plus as you can even save some more money. It is enough to serve 4-5 cats for 3-4 weeks.


The perfumed scent of this cat-clumping litter is certainly not everyone’s cup of tea. I was fine with it, but it is normal for others to find it a bit too strong. Some cats may not like its sandy texture as well.

  • Clumps slide easily for scooping and don’t stick
  • Superior odor control
  • Low dust and tracking
  • Reasonably priced
  • The sandy texture is not for every cat
  • Some people might be uncomfortable with the added scent

#2. World’s Best Cat Litter – Best Corn Cat Litter

World's Best Cat Litter

Buy it on Amazon

Corn-based products like this can clump surprisingly well. If you’re eco-conscious and want to expose as little chemicals as possible to your cat, have a look at World’s Best Litter.

The corn absorbs liquids quickly upon contact, just like how the Arm & Hammer Slide works. It was a breeze for me to scoop this natural litter when cleaning as it had already taken care of everything. The corn granules turned all the waste into small solid clumps that didn’t stick to the bottom or sides of my box.

These tight clumps kept their structure and shape on removal as well. The World’s Best didn’t fall apart easily when scooping. But the cool thing is this corn cat litter is flushable and didn’t cause my toilet any trouble. In the first few days, I maintained a regular cleaning routine. The fibrous material absorbed the odors well enough. There were no bad smells to get up my nose during that period, even when I sniffed it real close.

However, this impression didn’t last long. When clumps started to build up in the box, it wasn’t hard to notice a mild odor. It isn’t horrible by any means. But if you want to contain the offensive smells all the time, you may need to change this unscented litter more often.

To people with allergies, the low-dust nature is an appeal of this item. Some dust may appear when pouring or scooping. But it’s minimal and settles back to the box quickly rather than staying airborne and attacking your sinuses.

Likewise, this cat litter doesn’t track much. There were some of it around the box, but in a much lower volume than what I anticipated. The substrate didn’t follow my cats everywhere, especially when compared to other lightweight natural litters like walnut or grass.

For an all-natural, biodegradable product, I didn’t expect this cat litter to be this affordable. Some options are cheaper per pound. But considering how it is made and the benefit to your cat and the environment, it is worthwhile.

The brand recommends one 28-pound bag can last for at least 30 days with two cats. My observations tell me that this estimation really matches reality. For the same amount of cat litter, it can outlast many other competitors.


As amazing as it is, this cat litter can’t escape the inherited downsides of corn. You will need to pay extra care to storage, or it may get ruined by excessive moisture or grain mites.

  • Biodegradable
  • Highly absorbent
  • Form firm clumps
  • Lightweight, easy to handle
  • Low dust and tracking
  • Cheaper than most natural products
  • Odors get worse fast without regular cleaning
  • More expensive than clay-based products
  • Prone to moisture and bugs

#3. Nature’s Miracle Intense Defense Clumping Cat Litter

Nature's Miracle Intense Defense Clumping Litter

Buy it on Amazon

This Nature’s Miracle model works well enough for most situations. It is a great choice if you want to avoid the strong scent of the Arm & Hammer Platinum Slide, for instance.

In my testing, this cat litter created hard clumps that encased the solid waste thoroughly. Even when I left them there for a few days, the clumps stayed that way and didn’t lose their shape. Cleaning was straightforward as well. Unless you let the box be full of urine, this product won’t fall apart and make a sticky mess in the box, which will make your cat extremely uncomfortable.

Nature’s Miracle offers both scented and unscented versions of the Intense Defense. The fragrance isn’t too harsh and helps the cat litter manage unpleasant odor fairly well. My little box was busy all week, but the odors couldn’t escape it.

When I poured this cat litter, the Nature’s Miracle Intense Defense did kick up a little dust. It was more than expected, but I don’t see it as a deal-breaker. Because of the dust above, tracking does occur. I was worried about it at first. But after getting used to it, the issue wasn’t serious. Compared to some products that can create a mess everywhere, it was a real blessing.

The pricing of this product is in line with most clay-based products. You have the option to pick up the massive 40-pound bucket, which lasted beyond my test duration.


The box is a bit flimsy, and the lid of the plastic container can’t close properly. They created a big mess when I unpacked my box. The unscented clay version actually gives off a light smell as well.

  • Clump very well
  • Hard and stable clumps
  • Minimal dust and tracking
  • Outstanding odor control
  • Pleasant scent
  • Cost-effective
  • The fragrance-free version actually has a light smell
  • Packaging should be better.

#4. Fresh Step Multi-Cat Scented Cat Litter – Best Budget Cat Litter

Fresh Step Multi-Cat Scented Litter

Buy it on Amazon

A tight budget doesn’t mean you have to sacrifice the quality. The Fresh Step Multi-Cat is a prime example of how an inexpensive product can still give you good value for money.

This is what the Fresh Step Multi-Cat Extra Strength does best. The soft and fine texture allowed my cats to dig in and do their business. I didn’t have to wait long before tight clumps appeared in the box with no stinky crumbles.

However, it is just above average if you have multiple pets. Fecal matter doesn’t pose many issues to this product. But a high amount of urine every day can turn it into a mess.

This item comes with light Febreeze artificial fragrances to help fight ammonia odor. It gets the job done fairly well. But the heavy industrial scent of this cat litter is not for everyone. People and cats who are sensitive to smells may have a hard time stomaching it. This smell can linger for a long time and even stick to your clothes upon contact.

Even though Fresh Step claims this is among the best low-dust products, it’s not the case. Tiny particles flew in the air when I poured the litter. If you have an active feline friend, your floor and furniture may get covered by coats of dust everywhere.

This clumping cat litter seems to struggle in tracking as well. Too much urine doesn’t create a pasty mess difficult to scoop out. But it can also stick to the paws and get tracked all around the house.

A bag of 20 pounds can last anywhere between 10 and 14 days. For the price Fresh Step is asking, this cat litter is an excellent deal.


With that said, you should be mindful of the place you plan to buy this product. The prices appear to have massive differences between stores. You should not expect high-quality packaging from this cheap product. Be careful when opening the box, or you will have spills everywhere.

  • Low cost per pound
  • Good at clustering
  • Decent odor control
  • Not suitable for multi-cat families
  • Dust and tracking can create a mess
  • Too strong scent
  • Poor packaging

#5. SmartCat All Natural Clumping Litter – Best Unscented Clumping Clay

SmartCat All Natural Clumping Litter

Buy it on Amazon

If you loathe the dust created by every product you’ve used so far, give the SmartCat All Natural a try. It is the best in preventing dust from getting into your eyes or mouth when taking care of the litter box.

This clumping cat litter is an obvious choice if you want to stick with an eco-friendly product but not the dusty clouds created by the World’s Best. There was no dust for me to notice whatsoever.

Made entirely of grass seeds, the SmartCat All Natural is super lightweight. When the urine comes into contact, this cat litter creates hard balls with no residue.

It was easy for me to lift them out as there were no piles stuck to the box. The clumps weren’t clumpy or unpleasant to handle. I wet the clumps by letting them sit in a bowl of water. After a few minutes, they all got softer and went down to my toilet without a hitch.

The SmartCat All Natural isn’t quite there with the best odor-fighting abilities of other products. It started to stink quickly after a few days. The situation got worse when I accidentally broke up the clumps when cleaning. Some charcoal and zeolite did well as a workaround. But if you prefer a completely unscented product, you’re out of luck.

The SmartCat All Natural lasts longer than clay products. If you can endure the smells, it can look the same for more than 4 weeks.


Many cats may eat grass seeds out of curiosity. Additionally, there aren’t many stores carrying this litter. It may be out of the question if you need a quick emergency bag from your local stores.

The light nature of this glass-based product means it can stick and track everywhere in the house. If you don’t have a habit of vacuuming regularly to control cat litter tracking, this could become a big headache pretty soon. The only upside is that grass seeds aren’t hard to clean and won’t hurt your feet.

  • No dust
  • Lightweight and clump well
  • Flushable
  • Highly scoopable
  • Easy to clean
  • Pricey
  • Track easily
  • Limited availability

#6. Boxiecat Extra Strength Premium Cat Litter – Best Control Cat Litter

Boxiecat Extra Strength Premium Clumping Cat Litter

Buy it on Amazon

As far as advanced and effective odor control goes, this is the product I suggest you give a go. It makes a great choice for cat owners who love the proven ability to clump of clay-based products but need some improvements in odor-fighting.

This litter did live up to my high expectations, which came from the manufacturer’s big talks. It was locked in the waste’s bad smells very well. I left it for days and still couldn’t notice anything unpleasant. Boxiecat claims it uses helpful bacteria to do the trick. But the tight clumps also deserve some credit as they act as a bag and stop odors from getting out.

This award-winning litter clumps very well. It uses a minimal amount of granules to cover the waste, enough to prevent urine from reaching the bottom of the box. Even if your cat tends to pee on the side, the urine will still get soaked up entirely.

The clumps in my kitty’s box were easy to scoop as they all floated on the surface. I didn’t have to dig deep to search for them.

When it comes to dusty mess, Boxiecat Extra Strength isn’t the best. You may encounter some noticeable dust clouds puffing up when you dump the Boxiecat into the box.

However, there is no need for a face mask when using this product. And you get past the pouring; it creates much less dust than other clay-based products. Tracking happened, but nothing more serious than what I was waiting for. You should still be prepared to dust off your little mats often.

The standard Boxiecat product is already more expensive than most clay-based products. And to get awesome odor control, you have to pay even more for this Extra Strength version. Despite the manufacturer’s claim, it doesn’t seem to last longer than similar clay options. Some people may not find the extra cost worthwhile because of this reason.


You should not mix the Boxiecat Extra Strength with another cat litter. The bacteria can break down the other product and render it useless. This limitation may make the transition harder for your pets.

  • Superior odor-fighting ability
  • Clump fast
  • Little dust and tracking
  • No fragrances
  • Costly
  • Not suitable for mixing

Consider when you choose the best clumping cat litter for multiple cats

Clay cat litter

This was the first-ever material used in cat litter when Edward Lowe invented it in 1947. It is also the most popular choice with the ability to clump. According to, clay accounts for 84% market share.

Bentonite is the most common material used in modern clumping cat litter. Manufactures get it through strip-mining before breaking them down into pebble-sized granules.

Some of these litters consist of fine particles, and others are made up of larger pieces. But they all can absorb a great amount of liquid, then turn themselves into a soft, cement-like texture.

Cats also love clay because they can dig and cover waste easily. You can see how effective these litters are at clustering with this video.

  • Tolerated or preferred by most cats
  • Absorb liquids and create tight clumps instantly
  • Some with activated charcoal can control odors
  • Affordable and wildly available
  • Typically need less frequent changes
  • Heavier than other options
  • Not environmentally friendly
  • Non-flushable

Natural Material

This material has been dominating the market for a long time. But there is a slew of alternative clumping litter choices as well.

Consider the following plant-derived choices when you need something more eco-friendly or simply when your feline friends refuse to use traditional clay litters.

Corn cat litter

Some of the best products on the market, like the World’s Best Litter, are made of corn kernels. They are biodegradable and usually their natural cereal scent, not added harmful chemicals, to mask smells.

It is edible, so you won’t need to worry about your pets if they happen to eat some corn. Corn-based litters are also safe for cats that are infection-prone or just had surgery.

  • Biodegradable
  • Safe for ingestion
  • The natural scent that can minimize odors
  • Typically produce little dust
  • Expensive
  • The ability to clump varies between products
  • Many cats don’t like their rocky texture

Wheat cat litter

Similar to corn, processed wheat is also a good green choice to replace clay. They can cluster (to some extent) and lock away odors without using any added perfumes or dyes.

  • Biodegradable and septic-safe
  • Low dust
  • Need careful storage to prevent pests
  • Clumps are not as firm as those in clay products


Made from fibrous walnut shells, this cat-clumping litter features a sandy texture. They are soft and highly absorbent (even more than clay). The clumping variant can form tight clumps for easy scooping.

  • High absorbance level
  • Lightweight
  • Clump well
  • Low-dust
  • Track easily
  • Not suitable for people with nut allergies


They are harder to find, but grass products can also form clumps so you can scoop the waste out easily. Made of dried grass seeds, they are naturally lightweight and low-dust with a sandy texture.

  • Create little dust
  • Can clump well
  • Lightweight
  • Usually have no added chemicals
  • Track easily
  • Expensive and not readily available
  • Some cats may eat them


Made of fibers from coconut husk, these products virtually don’t create any dust. However, they don’t score a high clumping power if it is your top concern.

  • Dust-free
  • Compostable
  • Limited availability
  • Only clump lightly
  • Ability to clump

It’s up to you to decide which kind of clumping level works best for you. Tight and instant clumps are easier to scoop out from the box and leave only clean clumping cat litter behind.

Most cats also prefer this because they can push clumps aside with ease. But it isn’t always the case. Too tight clumps can stick to incisions on cats with recent surgery, for instance.



Like many products, consumers have become more conscious about how they’re made and the best and worst impacts they have on the environment. Natural formulas like corn are more eco-friendly and usually safer for cats. Some of them can be flushed down your toilet if you wish to do so.

Granule Size


This is another matter of personal choice. Some cat owners love formulas with fine and sand-like particles. They make wet stuff stick together more easily.

On the other hand, heavier and bigger granules are the favorite cat litter choice for others. Their kitties will have a harder time kicking them out of the box. As a result, there is less dust and tracking around their houses.



Most products produce dust in some way, but some are more problematic than others. A low-dust or dust-free cat litter doesn’t only help keep your furniture clean but also gives the health of you and your cat the best protection.

Dust can make you and your feline friends sneeze, cough, or even trigger your asthma conditions. According to experts at Cornell Feline Health Center, at least 800,000 cats in the US are suffering from acute or chronic asthma.

Some natural formulas are very low in dust. They are a perfect choice if you have any serious respiratory issues.



Tracking happens when the litter sticks to the feet and hair of your cats. This is a common “side effect” of litter, whose main purpose is to stay in the box as much as possible.

Clay clumping products tend to track more than natural formulas. Formulas with bigger and heavier particles like clay are less prone to this. Some with unique particle shapes are also trackless outside the cat litter box.

Odor Control


Compared to the non-clumping variant, clumping products usually have better odor-fighting capability.

To make bad smells even less of a problem, focus on products with charcoal or baking soda included. These ingredients provide the cat litter with another way to neutralize odors.



A natural or added fragrance can help mask the foul smells associated with waste as well. But sometimes, they don’t work as intended and even deter the cats.

These animals have a strong sense of smell, and many of them actually hate scented products when the pet owners have no problem with them.

Some manufacturers put out multi-cat versions in addition to regular products. They tend to have more antimicrobial and scent-control ingredients than the single-cat variant.

They are your best option if you have several cats. But this isn’t a strict recommendation, however, as many regular products can perform well with more than cats as well.

Cat’s Preference


At the end of the day, it’s your cat who uses the litter box. You may like the texture or smell of a product, but it may get rejected by your kitties right away.

Take into account what they like to use and give them some time to switch to a new clumping formula. Mixing new and old products is also a good idea. Your pets can enjoy the transition without an abrupt change.

Consider other conditions of your cat as well. If they have sensitive feet, avoid sharper granules from a pelleted or crystal cat litter.



The prices of cat litters range anywhere from under one dollar to several per pound. Newer and harder to source ingredients tend to cost more.

Also, pay attention to how long a bag can last. Some products are more expensive upfront. But since they are cost-effective, the amount of money required for the same duration is actually lower.
