Factors to consider when choosing a flushable cat litter

When choosing a flushable cat litter, there are several important factors to consider to ensure that the product is suitable for your needs and will provide the best experience for both you and your feline companion. Some factors to consider include:

  • Flushability and septic tank safety: Indeed, flushability and septic tank safety are crucial factors to consider when choosing a flushable cat litter. It is important to ensure that the litter you choose is designed to be flushable and will not clog pipes or damage your septic system. Some litters may claim to be flushable, but may not break down easily or quickly enough to be safe for use with a septic system.
  • Odor control: It’s important to choose a litter that effectively controls odors and is suitable for your cat’s needs. Some cats may have a sensitivity to certain types of fragrances or odor-control agents, so it’s important to choose a litter that is unscented or made of natural materials.
  • Dust and tracking: Some litters also tend to stick to your cat’s paws and be tracked around your home, making a mess. When choosing a litter, it’s important to choose one that produces minimal dust and tracking. Clay-based litters tend to produce more dust than other types of litters, such as paper-based or silica gel litters. However, some clay litters are now formulated to minimize dust and tracking. Another option is choosing litter made of natural materials such as corn, wheat or paper-based litters, which are known to produce less dust and tracking than clay-based litters.
  • Product name, brand, and description: Research the brand and product name of each litter and read the product descriptions to ensure that they meet your criteria for a good flushable cat litter.
  • Green and sustainable options: Consider environmental factors such as biodegradable materials, unscented litters, safe for sensitive paws, natural materials (e.g. green tea) and opt for eco-friendly options.
  • Natural litters: Some people prefer to use natural litters made of materials such as corn, wheat, or paper, which are biodegradable and safe for septic systems.
  • Artificial fragrances: Some litters are scented with artificial fragrances, which can be overwhelming or even harmful to some cats. If you have a cat that is sensitive to smells, it is important to choose an unscented litter.

How We Tested

When testing the best flushable cat litters, we considered several important factors to ensure that the products we recommend are of the highest quality and will meet the needs of most cat owners.

  • Flushability and septic tank safety: We tested the flushability of each litter by flushing them down the toilet and observing if they broke down easily and quickly without clogging the pipes or causing any damage to the septic tank.
  • Odor control: We evaluated the odor control capabilities of each litter by filling litter boxes with them and leaving them for several days. We then assessed the level of odor present in the room and around the litter box.
  • Dust and tracking: We observed how much dust and litter were tracked outside of the litter box during use. We also checked for any dust when pouring the litter into the litter box.
  • Price: We compared the price of each litter to others on the market to see if they offered good value for money.
  • Product name, brand, and description: We researched the brand and product name of each litter and read the product descriptions to ensure that they met our criteria for a good flushable cat litter.
  • Green and sustainable options: we also considered the environmental factor of the products, for example, biodegradable materials, unscented litters, safe for sensitive paws, natural materials (e.g. green tea) and we made sure that the product is eco-friendly.
  • Convenient and eco-friendly disposal: We evaluated how easy it was to dispose of the litters, and the options available to users.

We also took into account feedback from other cat owners who have used the products in the past, in order to get a well-rounded understanding of the performance of each litter.

#1: World’s Best Cat Litter Multiple Cat, Unscented


Buy it on Amazon

If you are an experienced cat parent, you must know about the renowned corn-based cat litter products from World Best Cat Litter. This flushable cat litter brand is high-profile for being natural and environmentally friendly and what’s more, all of its formulas have undergone harsh testing to confirm they are sewer and septic safe.

Designed for flushing in a well-maintenance system, World’s Best Cat Litter does a great job. I have four cats and two litter boxes, and I use one bag for each month. I keep the boxes in the bathroom, where it’s very convenient for me to clean twice a day by simply flushing them down the toilet. From my experience, I have never had a problem doing so.

A natural litter with long-lasting odor control

The manufacturer claims that this litter offers highly absorbent corn compressed into super-absorbent granules so it has an outstanding ability to clump and control odors.

However, due to the environmentally friendly formula and being suitable for flushing, the clumps are not hard and easy to fall apart if you try to scoop them.

But it’s no big deal, here is the tip for you: Just maintain the litter level at 4-5 inches in the litter box so that the urine can’t get close to the bottom of the pan.

Offers low tracking and less mess

Unlike the clay and other corn litters, The World’s Best Cat Litter Multiple Cat doesn’t produce big dust clouds so you and your cat can breathe easily. Although there is some dust with this litter reported by some customers, it is not a problem for your cat’s health.

This litter is declared to be made with natural and renewable ingredients, containing no synthetic additives, chemicals, clays, or perfumes. It is made from sustainably grown ingredients—not mined or drilled using heavy equipment.

Accordingly, it is safe for cats of all life stages, especially kittens at over eight weeks of age.

On top of that, what makes this litter at the top of our list is its long-lasting performance. The manufacturer clarifies that it lasts 2x longer than other flushable cat litters available on the market now, depending on the number of cats and frequency of litter box use. One small 8lb World’s Best Cat Litter bag lasts more than 30 days for one cat. This cat litter is available in sizes of 8lb, 10lb, and 25lb.


Although it is easy to scoop this cat litter, sometimes when you try to scoop it, some flakes of urine-soaked litter that are too small for the scoop might fall apart and get mixed in with the clean one.

Besides, if you use the unscented litter, it might not absorb the smell well. Instead, you should use ones with a lavender scent, especially when your Tom has stinky poop.

Let’s face it, World’s Best Cat Litter is made of natural ingredients so it may attract some bugs if they find access to the litter. Don’t worry I’ll give you a hand: remember to seal the package or store it in a sealed container and then place it in a cool, dry place. Do not put your litter boxes outdoors in humid locations if you don’t want to shorten the litter’s lifespan.

  • Flushable and septic safe
  • No added scent
  • Long-lasting performance
  • Lightweight, 99% dust free

#2: Cat’s Pride Lightweight Clumping Cat Litter

Cat's Pride Cat Litter

Buy it on Amazon

What’s special about this litter is it’s safe to flush and does not contain sodium bentonite, which can make your pipes clogged. Over several years, this cat litter has been tested and proved flushable in non-septic systems designed and maintained by plumbing standards.

To ensure flushability, just flush one or two clumps at a time, and remember to remove clumps from the litter box daily. Also, avoid cat litter or waste from sticking to the sides and bottom of the box so that cleaning up will be no sweat.

Powered with Baking Soda and lightly scented

Another positive quality this litter has to offer is the excellent ability to control odor. We much prefer this flushable cat litter to other traditional clay litters as it is powered with Baking Soda and lightly scented with ingredients that pass a safety review by the scientists.

We found the fresh scent to be very light and pleasant, and what’s more important is that the fragrances it releases are safe for us and our four-legged friends. It can remarkably control odor for up to 10 days and maintain the fresh air around your house if you scoop the waste out of the litter box regularly.

Tight hard clumps

This litter also clumps very effectively with tight hard clumps for easy clean-up. In testing this litter, we notice that it clumps well and forms clumps that are very easy to scoop away. It is made from natural minerals to provide cat parents with the powerful clumping for a stress-free cleaning process.

Made from naturally porous, light-density clay, Cat’s Pride Cat Litters are lighter in weight than other traditional scoopable litters, so you can carry some jugs at a time without all the heavy lifting. Over the time using it, you will find this litter has some other superior performances like long-lasting, strong clumping, and low dust.

The manufacturers also claim that they donate one pound of every jug of Cat’s Pride litter purchased to shelters, which will help more shelter cats find their forever homes.


Some users said that they dislike the smell that this litter has. Though this formula does a good job of forming hard clumps and controlling odor, it is a little bit messy. It produces some dust when it is first poured into the tray and it tracks sometimes.

  • Flushable in non-septic systems
  • Lightweight, get 50% more litter per pound
  • Powerful odor control with scented formula
  • Hard clumps for easy clean-up
  • Cheap
  • Not every cat parent will like the smell

The first thing you will notice about this K Kamy’s zoo – I am Tofu cat litter is that it’s made from soya bean and corn starch. This feature makes it water-soluble because it can instantly dissolve in water and it’s safe to flush.

To effectively discharge the litter down the toilet, you need to use the scooper in the septic system to break it down into smaller chunks before flushing.

This litter is clumping, so it needs enough amount of water to be flushed. From my experience, when not provided the correct amount of water, it will just absorb the water and then leave bigger particles and even mush in the toilet, so make sure you supply water of about 4 times more than its weight to ensure a smooth discharge.

Besides, do not throw a large amount of waste into the toilet at once as it may cause the drains to get clogged.

Strong deodorizing power

Made from activated carbon, charcoal, and natural aromatic oils, I am Tofu features a strong deodorizing power.

This flushable litter is available in 4 options: original no scent, green tea, honey peach, and charcoal, all of which are great at controlling odor. It all depends on your personal preference to choose from and figure out which is best for you and your Tom.

I’ve tested all these four options and the peach scent is my favorite due to its decent and not overwhelming smell. I can also tell that my beloved friends and many other cat parents love it too.

Besides, the absorption ability of this cat litter is also the way to go. I was very surprised that it can absorb 4 times their weight, much faster than other regular clay clumping litters. This natural clumping litter is highly absorbent and it can clump within just a few minutes, which negates scraping the sides or bottom of the litter box. Not bad!

99% non-dusty

While using this tofu litter, we found it 99% non-dusty, and sweeping it up is not a big problem.

Thanks to this quality, cat parents can feel safe keeping the risk of respiratory and eye disease for their felines and families at bay.

With some customers who are training their cats to use the toilet, they reported that unlike some other flushable cat litter this one doesn’t get tracked around the bathroom floor so it ensures a hassle-free cleanup.

This flushable cat litter is made from 100% soybean & pea fiber, it also doesn’t contain any synthetic additives, chemicals, and clay. With extra thin pellets, it’s incredibly gentle on the cat’s paws.

One of the advantages of tofu litter is that it’s biodegradable and safe to ingest, but we still recommend not letting your felines eat a lot of it.

If you care about the health of our planet, you should consider this cat litter because it can easily dissolve in water and can be used as compost.


Well, I am Tofu also received some negative reviews from users who reported that it’s not 100% trackless. It does track sometimes when your cat scratches it out of the box, but every cat litter does. We tried more than 20 different types of litter and this type turned out to be the best.

Just keep in mind that after opening, do not store the litter in a humid place, otherwise, the condensation property may decrease and the shape may be deformed.

  • Fast dissolve and safe to flush
  • Safe for consumption, eco-friendly, and healthy for cat
  • Great absorption
  • Excellent odor control
  • 99% dust-free, virtually no tracking
  • Doesn’t last long so more expensive than other flushable cat litters

#4: ökocat Dust-Free Natural Paper Non-Clumping Cat Litter

ökocat Natural Paper Cat Litter

Buy it on Amazon

Made entirely from reclaimed, clean white paper fiber, ökocat Natural Paper Cat Litter is a great alternative to litters of other traditional materials. It is very easy to flush. All we have to do is simply discharge the waste into the toilet and flush them down. No clogging, no need to flush twice, it’s completely hassle-free for many cat owners who are too tired of searching for a product that could dispose of their cats’ feces and urine in just one flush. Still, we recommend flushing in small quantities to ensure the most effective removing performance.

Strong odor-controlling power & absorption of urine

What makes this flushable cat litter incredibly special is its strong odor-controlling power. Without any added scents or fragrances, Oko Cat Litter’s paper fibers made me satisfied. They are highly absorbent and can absorb all the liquid super fast, keeping my cat’s feet dry and making cleanup quick and easy by simply scooping out the soiled pellets daily.

Plus, it doesn’t combine with urine to make any fouls. These natural pellets are enhanced with long-lasting, plant-based odor control to overpower the smell of ammonia. Some other cat parents reported that it has a slight paper smell but it’s not bad.

One of the advantages we love about this litter is it’s lightweight compared to many other regular litters, so no heavy lifting is needed.

Another huge plus is that it doesn’t get stuck in my kitties’ fur and toes, and no airborne dust is given off so it’s ideal for your cats’ health, especially cats with respiratory issues and also families with allergies or post-surgical needs.


Unfortunately, you should expect to pay some extra bucks for this litter as it is one of the most expensive options among Oko Cat Litter product lines. Though this formula does well in stress-free flushing and odor-controlling, it’s fairly messy. Sometimes, it does get tracked out of the litter box, but it falls off my kitty’s paws within a couple of feet.

  • 100% dust-free, quick absorption
  • Flushable
  • Long-lasting odor control
  • Safe for cats with respiratory problems
  • 100% biodegradable and planet-friendly
  • Lightweight fibers spread around easily

#5: sWheat Scoop Multi-Cat All-Natural Clumping Cat Litter

sWheat Scoop Multi-Cat All-Natural

Buy it on Amazon

This wheat-based cat litter is claimed to be flushable, it’s safe for septic tanks and city systems. There’s no more running out of your apartment to the dumpster or landfill with a bag of waste that Tom deposited in. While using this cat litter, we found it did the trick, it’s never clogged the toilet. Keep in mind that it’s necessary to scoop daily and just discharge a few clumps at a time into the toilet. Allow them to sit for about 20 minutes before flushing.

Another outstanding feature that SWheat Scoop has to offer is its powerful ability to control odors. Thanks to the brand’s innovative technology, the all-natural wheat materials perform quite well in neutralizing the smelly odors found in the litter box. All the bad smells are eliminated quickly without the use of any added perfumes.

SWheat Scoop is designed to clump quickly and firmly to lock away the urine odor on contact. Make sure to keep the litter box depth of at least 2 or 3 inches and give it time to form a relatively hard clump before scooping, usually an hour and a half or two hours is ideal. Also, since it’s short-term clumping, remember to sift or scoop twice a day to prevent dealing with several pieces of wheat husk.

This product doesn’t contain added dyes or perfumes and it is 100% biodegradable, which makes it beneficial for sensitive cats and owners. It’s also recommended by veterinarians thanks to its natural ingredients that are safe and healthy, especially for cats suffering from breathing issues. Plus, it’s formulated specifically for multiple cat households, even with just one cat using the litter box, for efficient odor-fighting power.


Some customers said that they still notice some fouls that cling to the litter box. Though it doesn’t prevent the stinky odors completely, it can keep them under control. If your four-legged friends’ waste stinks too bad, you can apply my trick: add baking soda to the litter, this will provide much better performance. Also, it requires regular scooping so clearly, that it’s not much of a hassle-free cleanup.

  • 100% biodegradable
  • Flushable
  • Great for multiple-cat homes
  • Highly recommended by veterinarians
  • No added fragrances
  • Doesn’t deodorize quite well
  • Clumps disintegrate quickly

#6: Garfield Cat Litter Ultimate Clump

Petfive Garfield Cat Litter Ultimate Clump

Buy it on Amazon

Petfive Garfield Cat Litter Ultimate Clump has been tested and ensured 100% sustainably biodegradable and flushable. The makers have optimized this litter to be septic safe. We love that it’s easy to flush and clean.

It’s important, however, to let the clumps soak and dissolve first.

To avoid any clogging problems, leave the waste in the toilet bowl for about 20-30 minutes until it dissolves the clumps enough to be flushed easily. Also, as the litter does such a great job at clumping, do not flush clumps older than 12 hours or more than 2 clumps at a time.

One of the most outstanding features of Petfive Garfield Cat Litter Ultimate Clump is its natural long-lasting odor elimination property – thanks to its cassava and corn ingredients. Without any added artificial fragrances, this cat litter makes several cat owners satisfied by instantly locking up the urine smell and preventing it from spreading around the apartment.

The materials themselves quickly clump when they get wet. We found that the litter absorbs more liquid, 3 times more powerful than clay in forming tight rock-hard clumps. This means that there’s no risk of stains or clump breaks when you clean up the litter box. It’s such my lifesaver in terms of ease because it clumps up very quickly right after my big boy does his business and it doesn’t stick to the side of the litter pan.


The small extra-fine grains that this formula offers are incredibly soft on your cats’ paws and help eliminate dust effectively. It’s ideal for multi-cat homes and is one of the best flushable cat litters for cats and even humans with respiratory problems. Plus, the white color and fine texture of the tiny grains allow for easy detection of the urine’s color change, which is a sign of early-stage health issues.


Unfortunately, tracking could be a problem with this litter considering its fine texture. It tends to get sprayed out of the box when being covered. To solve this problem, I recommend using a litter box with a higher wall and placing a mat at the entrance of the box, this could reduce tracking a lot.

  • 100% biodegradable
  • Clumps instantly and forms rock-hard clumps
  • Flushable and septic-safe
  • Natural odor control
  • Allow for easy detection of health issues due to abnormal urine color
  • Soft on cat’s paws
  • Fine grains spread around easily

#7: Petfive Sustainably Yours Natural Sustainable Multi-Cat Litter

Petfive Sustainably Yours Natural Litter

Buy it on Amazon

Like other flushable cat litters, this litter helps to save our planet by not creating more plastic waste by filling plastic bags with our cat litter each week. Petfive Sustainably Yours Natural Litter is designed to be flushed down the toilet as it’s completely sewer-safe. Well, this formula has quite fine grains so it takes time to soften and dissolve.

To avoid clogging the drains, let the clumps sit in the toilet for 15 minutes before flushing them. Plus, when I experimented with flushing small amounts of litter (1 or 2 clumps) at a time, I found no problems at all, the cleanup is completely stress-free.

Clumps are firmer and faster

Made from corn and cassava, Sustainably Yours is 100% natural, renewable and biodegradable. It is rich in starch, which has the ability to form incredibly robust clumps super fast when liquids come into contact. These clumps can be effortlessly scooped out without falling apart or breaking.

Plus, another huge pro is that it doesn’t stick to the side or the bottom of the litter box, you can easily clean the litter pan without scraping it.

Stops odors on contact

Also, unlike regular plant-based litter, the solid clumps can suppress the growth of bacteria in a natural way, helping to lock away and eliminate the offensive odors around your house. The corn ingredient in Sustainably Yours has powerful odor-fighting properties. It immediately entraps the fouls without any added chemicals and consequently eradicates them, no matter how many cats you have.

Low dust, chemical, and fragrance-free

Without any chemicals or fragrances, Sustainably Yours is designed with a proprietary technology that produces no dust at all. Even when filling the litter box with this litter, I didn’t find any powdery cloud of dust as with many other clay litters.

If your felines suffer from respiratory problems or you have allergies to dust, then this product might be the right one for you.


As a matter of fact, litter is going to track no matter what kind you use. In testing this litter, we found it does track sometimes. Because of the smooth, sand-like texture, it was fairly messy when our pets got out of the box.

To solve this problem, we placed litter-catching mats under the box to catch any scattered particles around.

  • 100 % biodegradable, renewable as compost
  • Safely flushed down the toilet
