More Information

Unfortunate Information: This product is not very compatible with self-cleaning litter boxes. If you’ve got an aversion to cleaning the litter box the old fashioned way, then you will probably want a different brand from this list. If you’re old school then this litter will have you saying great things about it!

Pause and Think: This product changes its formula recently. While this makes it even better at clumping and capturing waste, and reduces the tracking throughout the house, it is slightly dustier than competitor brands.

Informative Details: Dr. Elsey’s is a Precious Cat company brand. This is an unscented litter designed for controlling odors. It works through moisture locking technology that reduces clumping and tracking.

Awesome News: The hypoallergenic formula is really great because it means even your finicky cats will not reject this litter. It’s the ultimate in bathroom comfort for your kitties. It also uses heavy granules, which will reduce the amount of liquid that hits the tray bottom. This makes for less scraping of nasty congealed litter from the bottom of your box.

World's Best Cat Litter Clumping Formula

World’s Best makes some perfect kitty litters, and you’ll go catnip crazy for their clumping formula!

This formula uses corn instead of clay, and doesn’t use the silica dust that ends up tracked all over the house.

This also makes it a decent choice for sneezy cats!

It clumps quickly, so a little bit goes a really long way with this brand.


  • Flushable formula
  • Very little dust
  • Ecologically friendly


  • Clumps can occasionally break apart, making for messier cleanup
  • Has a very distinctive smell
  • Pricier than comparable brands

More Information

Feline Features: This formula clumps very quickly, trapping odors away instantly and locking moisture in before it seeps through to the ray. It is 99% dust free so you can breathe easily and know that it won’t get tracked through your house.

Gives Some Pause: Sometimes, the clumps can disappear. The other disadvantage of corn is that, with an odor-free formula, you end up with the odor of natural products. Clay absorbs smell a bit better without having much of a distinctive smell itself. This isn’t the case with corn.

Perfect Formula: This formula is biodegradable, so you can easily flush clumps down the toilet as they occur throughout the day instead of having messy litter build up that crowds litter boxes and gets carried out to sit in the large trash bin until garbage day arrives.

Buyer's guide for the best clumping litter for cats

If you’re a new cat owner, you may have a lot of questions. This guide will answer a lot of the most frequently asked questions about cat litter so you can make an educated and informed decision that will be best for your cat and your home.

what is clumping cat litter?

Clumping litter nearly always uses sodium bentinite. This is special clay that clumps naturally when it takes in moisture. This makes it easy to scoop and dispose of soiled kitty litter. To work properly, no matter what material it uses, it needs to be extremely absorbent.

This is nice because it means you don’t have to empty the entire littler box nearly as often, which saves money. Instead, just toss in fresh litter as needed between cleans. Litter that doesn’t use a clumping formula has to be regularly emptied to avoid the entire bottom being a pool of cat urine. Without being able to clump and bond to the litter, it just spreads out across the box and settles.

things to consider when looking for the best clumping cat litter:

Cat litters are all different. Even within the category of clumping cat litter, there are several different methods and formulas to think about. This is why there’s not a single, best option to use. This is especially true when you factor in that cats have different preferences and can be more persnickety than their owners!

The most important factor is obviously how well it clumps. The entire point of buying clumping litter is so you can scoop the clumps easily. This means that if your clumps aren’t super hard and solid, you may as well not use it.

You also need to consider whether or not you want a scent. People have been debating which one is better for a while, and no solid conclusion has been reached.

If you decide to try a scented clumping formula, make sure that they also contain an odor eliminating scent, otherwise you’re just covering the smell with another smell instead of eliminating it. Don’t buy a huge package, either, because cats are picky and if they can’t stand the smell, they will refuse to use the litter.

None of the litters on this list are scented, because that can often make it more difficult to be accepted by your cat. It also may lead to allergies, and many scents do not mix well at all with litter box odors. Conversely, unscented formulas smell like their source materials, so a lot of people complain of a funky smell that is only a little better than the litter scent.

This leads to odor control, which is different from scent. Odor control is what actually attacks and eliminates the smell of your litter box. Extra odor protection can completely eliminate litter box smells without adding a cloud of perfume to your home.

Dust is another factor in every cat litter. Some cats are extremely sensitive to dust particles, so you will want to find a dust free formula doe them. This can also settle around your house and create an icky cat litter film, which is not pleasant.

Eco-friendliness can be important to a lot of people. More and more cat litters are becoming biodegradable, but not all of them are. Make sure you know what you are getting into when it comes to disposal, because while several of the litters in this list are flushable, very few clumping cat litters actually are.

how do i know when to change clumping cat litter?

This answer is different for everyone because it depends on a lot of different factors. If you have multiple cats, or if your cat uses the litter box more frequently than most, you will need to change your litter more quickly.

Several pet owners change their litter on a set schedule. Clumping cat litter needs to be completely emptied and cleaned less regularly than normal litter, so many people just change it on trash day.  If your litter starts to smell more noticeably, or look wet, then it is definitely time to go ahead and change it.

You should be scooping out the solid clumps regularly as your cat uses the litter box. Once you do, you need to go ahead and refill it so that there are always at least 3 or 4 inches of litter inside the box.

will you ever need to switch your litter?

This is a tricky question, and it largely depends more on your cat than you. A lot o cats will go their lifetime using the same litter and if you try to switch their brand, they get upset. Other times, subtle changes in the formula from the manufacturer that go unnoticed to you make the difference between acceptance and rejection to your cat.

If you get a new cat that does not like the one you are using, you may need to start hunting for another type of litter. This can be more difficult since your other cats have already adjusted to the current brand, but with so many available you can find a formula that all of your cats will use.

If you are noticing that you have to clean the litter box constantly, or your clumps aren’t hardening regularly, it may also be time to look around for other options.

If your cat doesn’t seem to be using the litter box as regularly as they used to, it can mean they are sick of the current formula and want a change. If they start tracking the litter through the house, then you may be ready to change, too.

Just remember that when you are switching litters, you should buy trial sizes or see if your vet has some sample packages on hand. Cats are extremely picky and it may take you a few tries to find the right option.

cat kittens use clumping litter?

This question has been debated hotly, but ultimately it has been determined that there is no scientific proof that clumping cat litter is harmful for cats. That being said, no cat litter is safe for curious kittens that frequently put things in their mouth.

Small amounts of litter that get accidentally ingested can easily make their way through and out again in very little time. Larger clumps may be too big to break down and end up causing blockages.

In the end, there is no evidence that says clumping cat litter is unsafe for kittens, but you know your pet best. The ASPCA recommends that if you are in doubt, you should wait until your cat is 3 or 4 months old before using it regularly.

can you mix clumping and non-clumping litter?

You can, but this is not recommended unless you are desperately close to being out of litter and don’t have time or money to run for more while you wait for your internet order to arrive.

Remember that cats are picky. If you mix 2 litters together, they may reject it for any number of reasons from the smell to the texture. If you are mixing, start slowly and use more of what they are familiar with than the new stuff.

Mixing it will also drastically reduce the effectiveness of your clumping litter. Those formulas are blended specifically and perfectly balanced. Adding non-clumping litter to the mixture will make it harder for the clumping formula to reach and absorb the liquid, and result in the type of clumps that will fall apart easily instead of remaining bonded together.

are there any natural cat litter alternatives?

There are several natural alternatives to traditional cat litter for ecologically minded people. While you can use them safely, many of them are far less effective than litter, so you may not get the best results – especially when it comes to odor elimination!

The upside is that many cat litter companies have begun looking into eco-friendly, biodegradable formulas. In fact, a couple of the options on our list already use some of these natural alternatives.

Corn is one of the most common biodegradable cat litter alternatives. This is unscented and clumps extremely well, so it makes a great option. The downside is that it tracks through the house a lot, no matter what you do.

Grass also works for cat litter. It’s the most natural option there is, and it has worked for wild cats for generations. Grass is light weight, dust free, doesn’t track, and lasts a long time. However, it’s also very lightweight so cats may not like it if they’re heavy. Several of them end up sinking or knocking over the box.

The ASPCA has suggested walnut shells before, too. They are not toxic to cats, they clump well, and they control the odor better than other natural remedies. The down side is that it is difficult to break them down into the right size pellets and it will track everywhere and stick to your cat’s paws. A lot of cats hate the stuff.

Wheat is a lightweight litter and smells nice naturally. The down side is that it gets everywhere and does next to noting about odor control. On the plus side, it clumps well and flushes easily if you’re not allergic.

Wood pellets are a great option, and one of the brands on this list is made from wood. It is highly absorbent, but can’t be scooped because the scoop holes are too small for large pellets. Be careful what you grab with wood, though, because if they have adhesives, finishes, or additives those things may be extremely toxic to your cats.

conclusion for these clumping cat litter reviews

Now that you have learned about what clumping cat litter is and had some questions answered, you should be ready to find the right litter for your cats. Remember that it is your cat’s decision as much as yours at the end of the day. If your cat refuses to use the litter you have chosen, then there is nothing you can do except find another option.

Remember that clumping cat litter reduces the need to frequently change the litter box and clean it, but it does not eliminate this need. You will still need to completely empty and refill your cat’s litter box on a regular basis to prevent odors and ensure health.

Practice safe cleaning standards. Cat urine contains a lot of potentially hazardous materials, so you want to wash the box somewhere that you don’t also wash food and scrub your hands thoroughly afterwards.
