Buy it on Amazon

Made from whole corn kernels, the World’s Best Cat Litter Scented Clumping Litter is naturally free of silica dust. Its granules are all lightweight, so carrying a large batch of them should be easy on your back.

This litter also features a 100% all-natural-scented lavender oil, which adds a fresh floral fragrance to the litter box and helps in regulating the odors from your cat’s waste. It doesn’t have any synthetic chemicals or perfumes, so the litter is hypoallergenic.

With many cat owners relying on the World’s Best Lavender-Scented litter, it has become a renowned litter formula and can be easily considered as the best clumping flushable cat litter. Its excellent clumping and odor-controlling features make it ideal for homes with two or more cats.

Flushable Ability – The manufacturer itself claims the flushable ability of the World’s Best Cat Litter. The litter has been designed to flush and work with well-maintained septic systems.

In my experience so far, the World’s Best Lavender-Scented Cat Litter has indeed simplified my daily chore of maintaining the litter box hygienic. I only have to scoop out the little clumps of litter along with my cat’s solid waste. And then I put them into the toilet bowl.

To keep my pipes clog-free, I simply flush 1 to 2 clumps at a time in the toilet. Having used and flushed this lavender-scented litter for years now, I’ve never experienced having to call for the help of a plumber. Yep, I guess the flushing simply works, saves me time, and keeps me from using any more plastic bags for litter disposal.

Dust/Tracking – As I’ve mentioned above, this litter’s granules are lightweight. So, they could get kicked out of the litter box more easily, and it can be a bit messy. You might also observe a bit of dust, but it is not that significant. More importantly, it contains no silica or clay dust since it’s only composed of whole corn kernels and all-natural ingredients.

#2: Garfield Cat Litter All Natural, Fast Clumping, Purrfect for Multi-cat Homes – Flushable Cat Litter For Odor Control

Buy it on Amazon

Made of both corn and cassava, the Garfield Cat Litter – All-Natural Fast-Clumping Formula is a biodegradable and flushable litter. It features fine grains that not only is preferred by sensitive paws but also enable the litter to clump as fast as possible.

In fact, many cat parents appreciate how they wouldn’t have to worry about clump breakage when using this Garfield Cat Litter. It also has no added fragrance, making it suitable for felines that are super sensitive to scents.

Finally, this litter’s light color allows you to easily notice the changes in your kitty’s urine coloration. This is such a special feature that can help you track a feline health issue, so it’s something that veterinarians approve and recommend.

Flushable Ability – The makers of Garfield Cat Litter have tested and ensured the flushable ability of this litter. They’ve optimized this litter to be septic-system-safe.

It’s important, however, to know how to dissolve cat litter first before flushing it. To avoid any clogging issues, just let the clumps soak and dissolve in the toilet bowl before flushing them. Also, avoid flushing clumps that are already older than 12 hours. This means you have to scoop out the clumps from the litter box more regularly, or as much as twice daily.

Finally, be sure to flush only a couple of clumps at a time, and not more.

Odor control – The Garfield All-Natural Fast-Clumping Cat Litter offers an effective odor control — thanks to its corn and cassava ingredients. These plants have properties that can encapsulate odors naturally. So, this Garfield cat litter is quite a great candidate for being one of the best cat litters for odor control while being flushable at the same time.

Dust/Tracking – The sophisticated and proprietary manufacturing process implemented in making the Garfield Cat Litter virtually eliminates dust. Thus, this litter is ideal for cats and even for humans with respiratory problems.

Tracking, however, could be a problem with this litter, considering its fine grains. To somehow get around this problem, I’d use a litter box with higher walls and place a litter mat at the entrance of the box. I’d recommend the same anti-tracking measures to you, too.

Long-lasting – The Garfield Cat Litter can help you save a few bucks in the long run. A 10-lb pack of this litter can last 30 days for one cat.

  • Biodegradable
  • 100% Natural
  • Instant-clumping
  • Forms hard clumps
  • Natural odor control
  • No added scent
  • Soft on paws
  • Flushable
  • Multi-cat ready
  • Allows for easy detection of abnormal urine color
  • Veterinarian-backed
  • May have a little wheat dust

#3: sWheat Scoop All-Natural Cat Litter, Flushable


Buy it on Amazon

The sWheat Scoop All-Natural Cat Litter is — as you might guess from the name — wheat-based. The ingredients have all been farmer-grown, ground up, and then packaged for you to use.

sWheat Scoop’s All-Natural formula offers an even stronger clumping compared to the Fast-Clumping variant. In fact, it clumps so well and hard after 5 to 10 minutes of untouched urine or wet granules.

Like the Garfield Cat Litter above, this sWheat Scoop Cat Litter doesn’t contain dyes or perfumes. So, it’s good for sensitive and picky cats that don’t like to linger around extra strong and artificial scents. This litter is also biodegradable, so it won’t pose a threat to the environment.

Otherwise, the company sWheat Scoop partners with the Best Friends Animals Society or BFAS. sWheat Scoop donates one additional pound of litter to BFAS for every new sWheat Perks member sign-up. These donations along with sWheat Scoop’s financial support to BFAS help save kittens who have been abandoned or are in need.

Flushable Ability – sWheat Scoop has confirmed that its litters are flushable. The manufacturers simply state that you shouldn’t rush your flush.

I’ve had an experience in using this litter, and it has somehow surprised me that the hard clumps can actually break down and be safer to flush if you just allow it to soak for a while. So here’s how you should do the flushing (based on the manufacturer’s instructions and my actual experience): Scoop a few litter clumps at a time and put them into the toilet. Then, you should let the clumps sit for 20 minutes to allow them to break up. Once they’ve broken up, it will be easier for them to move along with the water in your septic system. After 20 minutes, you can then flush.

Odor Control – The sWheat Scoop All-Natural Litter offers a stronger odor elimination feature than the sWheat Scoop Fast-Clumping formula. It can really control smells as long as you scoop the clumps and solid waste daily.

Dust/Tracking – This litter doesn’t stick to cat paws, so cats do not track it to all the other rooms in your house. You may, however, notice some wheat dust upon pouring the litter from the bag into the litter box. Still, it’s not as harmful as clay or silica dust.

Long-lasting – The sWheat Scoop All-Natural Litter is also cost-effective. One bag of 36 lbs lasts longer than typical clay cat litter products, so it can help you save a few more bucks.

  • All-natural
  • Biodegradable
  • 100% renewable resource
  • No dyes or perfumes
  • Noble ion technology helps neutralize odors
  • 2x stronger clumping than sWheat Scoop Fast-Clumping Litter
  • 2x stronger odor elimination than sWheat Scoop Fast-Clumping Litter
  • Flushable
  • Long-lasting
  • Prone to tracking with its fine grains

#4: Weruva It’s A Tea Potty! Hinoki Wood & Green Tea Natural Cat Litter, Flushable


Buy it on Amazon

Made of Hinoki wood and green tea, this Weruva Natural Cat Litter doesn’t negatively impact our planet. It’s certified clay-free and even grain-free, which means that it contains no wheat, no soy, and no corn. Thus, it’s quite a hypoallergenic litter suitable for super sensitive kitties.

The makers of Weruva Cat Litter ensure that even its pouches are BPA-free and recyclable, further reducing their environmental footprint.

Weruva Cat Litter products are actually family-owned for over 10 years now. The family owners are proud to responsibly source only sustainable raw materials to keep their products eco-friendly.

Flushable Ability – The manufacturers claim that the Weruva Tea Potty Litter is flushable. It’s just that they haven’t given instruction on how to flush the litter properly into the toilet, unlike the other companies.

Well, this Weruva litter have fairly larger pellets compared to the smaller and more refined grains of most flushable litters. Still, when I experimented on flushing small amounts of this litter, I found no problems at all. I only see to it that I don’t dump a large batch all at once. Also, when it’s time to change the entire litter box, I opt at disposing the litter into the trash instead of flushing everything down.

Odor control – One of this litter’s main ingredients is Hinoki wood. It has the ability to suppress the growth of mold and bacteria the natural way. So, it helps a lot in controlling odors. On the other hand, this litter’s green tea component contains natural antioxidants including catechins. Catechins also help in suppressing bacterial growth and the odors they emit.

Dust/Tracking – The Weruva Tea Potty Litter has very minimal dust, thanks to the pellet structure that feels more compact than the small grains of other litters.

In the same way, the pellets only cause very minimal tracking, if any. Occasionally, though, you might find a few pieces just outside of the litter box, especially if they got stuck on the fur of very long-haired kitties. Sometimes, a few little pieces can also get stuck on the pads of your cats’ feet, but they’re minimal compared to other litters with even smaller granules.

Long-lasting – The Weruva Cat Litter lasts quite long, too, depending on the number of cats and frequency of litter box use. A 6.7-lb bag of Weruva Tea Potty Litter can go for 10 to 30 days, while an 11.7-lb bag can last from 17 days to as long as 50 days.

  • All-natural
  • Eco-friendly and sustainable raw materials
  • Natural odor control with fresh green tea aroma
  • Clay-free
  • Grain-free
  • Hypoallergenic
  • Minimal dust
  • Minimal tracking
  • Clumps easily for scooping
  • Flushable
  • Clumping is not as tight as clay
  • Not recommended for a self-cleaning litter box

#5: Naturally Fresh Walnut-Based Alpine Meadow Scent Multi-Cat Quick-Clumping Cat Litter

Basic Product Information:

  1. Available in 4 sizes
  2. Made from the fibrous material of the walnut shell
  3. Great for multiple cat households
  4. Flushable
  5. 100% Natural
  6. Silica dust-free

Comprehensive Product Review:

From what we have experienced, both the odor control ability and clumping action of Alpine Meadow cat litter is perfect if you’re a parent of multiple cat kids. It’s also flushable to save your effort dumping the wastes into the bins. Let’s dig a little deeper.

Neutralize odor efficiently – Many applause for Alpine Meadow for the epic odor elimination. This walnut-based cat litter did not disappoint us, even better, it does a better job at trapping the smell than most cat litter we used from clay to pine to corn litter.

Fresh scent – We have been through many scented cat litter and notice that only a small portion of the available brand can extract the chemical smell out of their product. Alpine Meadow is one of them. Not only are we pleased with the smell but our cats also seem to be comfy when they are in the box.

You should always make sure your cat is comfortable with their cat litter. Because if they don’t, they won’t bother covering their dumps. Or worse, they might find another place to do their deeds and it could be anything from your rug to your couch.

Low dust – Even when we pour Alpine Meadow to the litter boxes or replace the litter, the dust is relatively low. Our cats like jumping and scratching in the boxes but besides some tracks on the floor, no dust is found flying around our house. If you and your kitties are sensitive to dust, we think this product can be a great helper.

Superb absorbent – As advertised, Naturally Fresh stated that Alpine Meadow absorbs three times better than conventional clay litter. We could see it absorb relatively well because less of this litter is used for the same work compared to other cat litter.

About the texture, the clumps went solid after roughly 20 minutes, letting you get rid of them with ease. You can scoop them out in one go because they won’t break down any time soon.

Drawbacks: Clumps doesn’t break down easily to flush down the toilet

As we mentioned, the clumps formed up nice and tight. But they are so tight that they hardly break down at all, so we could only flush them one by one down the toilet.

  • Excellent odor control ability
  • Fresh scent
  • Low dust
  • Easy cleanup
  • Hard to flush

What kind of cat litter is flushable?

1. Confirmed flushable by manual testing

Many flushable cat litters have been tested and found to be flushable and safe for septic systems. These tests are typically conducted manually by third-party companies. You should be able to see a verification tag on the label or package when looking for these kinds of litter.

If, however, there are no such disclosures of third-party tests, you may check the ingredient section on the packaging. Most natural ingredients are flushable, but you also need to confirm if they’re non-clumping.

2. With non-clumping ability

If you’re looking for a flushable cat litter, you should choose the type that has a non-clumping ability. But watch out for silica cat litter — the silica particles will expand within the pipes as soon as it gets in contact with water and get your pipes clogged. Because of this expanding property, silica litter is not advertised as flushable.

Some clumping litters, however, are made of biodegradable and septic-safe components. (They can still be flushed down the toilet, but only in small amounts at a time in order to avoid clogging). These components include natural plant-based materials such as corn, cassava, wheat, recycled paper or natural paper fibers, pine, other kinds of wood, and even green tea.

Frequently Asked Questions (FAQs):

1. Is flushable cat litter safe for plumbing?

The quick answer is yes. As long as the litter you’re using is tested and guaranteed as flushable, then it must be safe and pose no problems for your plumbing. Note, though, that you also need to be careful with the process of flushing.

Always follow the special instructions indicated in the packaging of flushable cat litters, if any. Again, the general rule is to let the litter soak and break down for a while before flushing, and to flush only a few pieces at a time, and your plumbing should work just fine.

2. Flushable cat litter brands

There are only a few brands that offer flushable ability across all its litter formulas. Here’s a quick list.

  • World’s Best Cat Litter
  • Ökocat
  • sWheat Scoop
  • Garfield
  • ​NextGen Pet

All of the World’s Best Cat Litter products are made of naturally-absorbent corn and have been tested and also proven flushable and septic-safe. Another brand that’s committed to environmental preservation and the manufacture of flushable cat litters is ökocat. All its products are biodegradable and flushable, as well.

You may also add the brands sWheat Scoop, Garfield, and NextGen Cat Litters to the list. These have made sure that their products are eco-friendly and safe for flushing.

3. Is Purina Tidy Cats litter flushable?

Purina Tidy Cats have many variants of litter, including the 4-in-1 Strength Clumping, the Instant Action Clumping, the LightWeight Glade Tough Odor Solutions Clumping, and the 24/7 Performance Clumping cat litters. You might notice that these are all clumping litters, and I just like to add that they’re not flushable.

Tidy Cats also has a non-clumping variant, but even this formula is not designed for flushing down the toilet.

4. Is Feline Pine flushable?

The Feline Pine 100% Natural Pine Original Non-Clumping Formula is not designed to be flushable, but some users have tried flushing small amounts and they seem to have no problems. The label on this litter, however, clearly advises against flushing. Instead, it says you should dispose of the litter into the trash.

Feline Pine also has a clumping variant. As I’ve explained above, clumping litters are generally not safe for flushing because of their ability to expand in water. So, the Feline Pine clumping litter is not flushable, as much as the non-clumping version is not guaranteed safe for flushing.

5. Is paper litter flushable?

The general rule is that any litter that contains clay or silica and other non-biodegradable components is not good for flushing. So, pure paper cat litters, without any of these components, are mostly flushable — but it’s not always the case either. To be sure, you would want to see from the label itself if the paper litter is truly suitable for flushing.

If you’d like to test a paper litter for yourself, you can. Try sprinkling a small sample with a little water, then put it in a basin of water. One good criterion for flushable ability is that the paper litter should be able to absorb small amounts of moisture when exposed to a little sprinkling, but the pellets must break down when they’re soaked. Just a side note and additional tip here: paper litters made of used newspapers are likely to be flushable.

Why should you use flushable cat litter?

Flushable cat litters are worth using for two major excellent reasons: simple disposal and environmental friendliness.

Simple Disposal

Flushable cat litters are very convenient for cat owners to use. There’s no need to pack the scooped pieces into a bag and dump it into the trash bin outside.

The added convenience of simply flushing the used litter along with the feces becomes even more relevant if you’re living in an apartment. It can be a little burdensome and time-consuming for you to drag bags of trash (with cat poop at that) down the stairs — and it’s not more convenient with the elevator. Just being able to dispose of the litter by flushing can save you all that hassle.


Other than convenience, using flushable cat litters have environmental benefits. You don’t have to use plastic bags that can quickly fill up landfills. Flushing your cat’s litter down the toilet simply treats the litter the way human waste is treated.

Cons of using flushable cat litter?

While using a flushable cat litter may have many benefits, it also has its share of disadvantages.

Aren’t designed for septic systems

Most cat litters are just not designed for septic systems. Surely, flushable cat litters could be an exception. But, in certain states and localities, septic systems haven’t been optimized to break down certain materials, including litter and feline fecal matter.

Is flushable cat litter septic safe?

If your home has its own septic system, it can make things a little more complicated. Your septic system may not have the same characteristics and design as the one used by manufacturers to test their product for flushable ability.

Keeping that in mind, you should realize by now that there’s not a flushable cat litter that works equally well for all kinds of households. Specifications matter most of the time, so you should better check with your builders or those that maintain the septic systems in your community if it’s okay to flush cat litter down your own toilet.

Introducing parasites into the waterways

Another disadvantage of using a flushable cat litter (and flushing it) is the possibility of introducing parasites into the waterways.

Some cat poop may contain the harmful parasite called Toxoplasma gondii. Scientific studies tell us that such parasites, once processed through human waste treatment sites, would just pass through without being destroyed. So, they could get washed out to the sea, continually harming marine life and even infecting people.

You see, most water treatment plants aren’t designed to handle cat poop — only human waste. Adding in cat waste and litter can double the burden of such treatment plants. If left untreated, pollutants such as these parasites can pose a serious danger to our water systems.

Which is a safe flushable cat litter?

A number of manufacturers have done their best to introduce environment-friendly and safe flushable cat litters. These products are composed of biodegradable ingredients such as corn cobs, wheat, paper, pine, and cedar.

It’s possible for small amounts of these substances to safely pass through pipe systems and even non-septic toilets. But, it’s still possible for these materials to cause clogging if they are dumped continuously and in large amounts through the pipes.

And that is why flushable cat litter manufacturers are vigilant at instructing you to scoop only little amounts to put in your toilet at a time. Most of them advise waiting for at least 20 to 30 minutes or even more just to allow the litter to soften and break down before flushing. This procedure should make the process safer for your pipes, but it could sound a little inconvenient for some.

The reason you shouldn’t flush cat litter

Despite the benefits of using a flushable cat litter, there are cases in which you simply shouldn’t.

If You Are Living in Coastal Homes

Aside from affecting our modern waterways, flushing cat litter may adversely impact our oceans — as I’ve just mentioned above. Now, the impact could be much worse if you are living in a coastal home, i.e., somewhere along the coastline.

In that case, your drainage system is most likely connected to the sewer. If you’re flushing the cat litter down the toilet, the waste will most likely end up in the sea. This would eventually put marine life in danger, getting exposed to the parasites that may be in your cat’s waste.

State/Federal Government Regulations

Because of the above reasons, certain states like California have imposed rules against flushing litter. It’s best to follow such federal government regulations if you’re living wherever they’re being implemented.

Problematic Plumbing System

Regardless of the abovementioned local policies, you may still think twice about flushing down litter if you have a problematic plumbing system in the first place. Think, instead, of an alternative solution such as disposing of those biodegradable litter particles in a compost pit and allowing nature to process them for at least a year to a year and a half.

Our Verdict

Among all the cat litter products that we’ve reviewed above, the World’s Best Cat Litter – Scented Clumping Litter Formula for Multiple Cats wins as our choice for being the best flushable cat litter.
