9 Best Flushable Cat Litter Brands Review – All Organic and Biodegradable
For our best flushable cat litter brands review, we isolated 9 environment-friendly brands that are both biodegradable and manufactured entirely from renewable resources.
While clumping is desirable, most clumping litter cannot be flushed without disastrous effects to the plumbing.
Additionally, clumping litter made from Sodium Bentonite could Kill Your Cat.
Consequently, a flushable cat litter brand that also clumps is both a rarity as well as something to look forward to.
The comparison chart below takes into account factors like odor control, clumping, dustiness, tracking, and whether or not a particular flushable cat litter brand is septic safe.

Better Way Flushable Cat Litter (
Made from Zeolite which is safe for cats and has distinct odor control and reasonably good clumping properties, this one is good to flush – but NOT if you have a septic tank.
Better Way Flushable Cat Litter Review – what’s going on?
There are mixed reviews, as with any other litter, but one in particular states that the cat suffered from an allergic reaction. You will notice the exact same review about sWheat Scoop as well and by the same reviewer. Exact, that is to say word for word the same review.
Of course, that makes sense if it is the same cat that got the allergic reaction but probably not a good reason to write off this brand altogether.
Instead, you might want to consult your vet before buying.
There are two peculiar problems with this litter and none of them have anything to do with the quality of the litter.
- The company seems to run out of stock frequently. This is a problem because cats are agitated when their usual litter is suddenly removed or replaced with something else. They will start peeing anywhere and everywhere.
- Bad packaging. Not resealable, and tends to get torn when you try to open the bag.
Blue Buffalo Naturally Fresh – efficacy and economy
Made from walnut shells, this litter has a huge fan following.
It can be flushed and is septic safe, completely biodegradable, clumps really well, and controls odor effectively.
Additionally, the company claims that one bag of blue buffalo clumping litter equals three bags of the leading clay clumping litter in efficacy and economy.
There have been some complaints about blocked plumbing after flushing this litter. If your priority is to find a litter that can be flushed, you might want to explore other options just to be on the safe side.
Cat’s Pride (Oil Dri) Jug (
Cat’s Pride flushable cat litter ingredients include Fuller’s Earth – as Ed Lowe’s Kitty litter (the first marketed brand of cat litter in human history) did. In that respect, we could call it Cat’s Pride flushable Kitty Litter. Don’t expect it to clump like Sodium Bentonite, however, and it doesn’t come cheap, either, but does the job pretty well.
Also, the company oversees the litter making from start to finish and makes sure the soil strata are replenished. They call themselves the ‘All American Brand’ if that appeals to you.
As for flushability, no, it is not safe for septic tanks. However, if you flush one or two clumps at a time you should have no problem with normal sewer based toilet systems. Again, you must schedule a time for cleaning /flushing litter because this could take a while.
Overall, a good choice even though it costs a pretty penny.
Garfield Cat Litter – three grades of graininess
This one’s completely plant based (corn and cassava), biodegradable, and relatively small-grained. There are three grades of graininess, actually. It is a good litter but you must allow it to dissolve first before flushing.
While that makes sense for a lightweight litter, it may not always be feasible to wait around while the litter does the dissolving act. If you have a time set aside after work for cleaning the litter box, this could work for you. Again, remember to let it dissolve first or you could end up with backed up pipes.
The ‘instant clumping’ is a fact. However, the clumping is not rock hard: Scoop carefully or the clumps may get pulverized.
This is a good, flushable cat litter, but the video (below) that they have to showcase the product is even better (as with any advertisement!): do take a look even if you don’t end up buying the stuff.
Natural and Clean Cat Litter (FLUTD and CRF friendly)
Natural and Clean is a UK based company of repute. This litter clumps well, does not attract insects and is flushable and compostable. It is made completely from recycled vegetable matter.
Contains the liquid waste really well (300% its own volume, the manufacturer claims). Controls pee smell really well. The poop odor, not so much. Oh well.
Next Gen Pet Flush Clean – wood and tea leaves
This wood litter manufactured in Japan is actually very good and tracks less as well. Great odor control, almost no dust, clumps relatively well – we would definitely recommend it.
It does have a low user rating on Amazon but if you read through them you’ll find some absurd and irrelevant reasons for low ratings.
The only problem is that it is scented and not all cats like it scented.
The solution here, if you otherwise like the brand, is to use their litter made from tea leaves. or the one composed of a combination of Hinoki Wood and Green Tea leaves. These are both good at suppressing bacteria, form reasonably good clumps to act as clay litter alternatives, and are flushable.
ökocat Natural Wood Cat Litter – 100% reclaimed wood
öko is German for ‘eco’ – implying that ökocat is eco-friendly. It should be, since it is made from 100% reclaimed wood. A lot of people swear by this brand’s odor control, and flushable and anti-bacterial properties and buy it in spite of the fact that it has some definite disadvantages.
It has minimal dust, but tracks Big Time!
It is a large grained litter and difficult to scoop. This, of course, is taken care of with a proper sized scoop. Hint: look at what Amazon suggests (‘Frequently bought together’).
ökocat is not really a new brand. It has been a leading natural litter brand in Europe for the last 15 years under the label ‘Cat’s Best’. Currently, everything is still manufactured in Germany but they plan to set up manufacturing in the US as well. That should bring down the cost.
Apart from reclaimed wood, ökocat also uses paper which is made by processing the same reclaimed wood.
The company does not use recycled paper on purpose since newspaper and other printed paper would invariably contain ink and dyes. They aim to make a completely safe and natural litter for cats and if you can get over the tracking issues, this could be The Flushable Litter you’ve been looking for.
Do not be alarmed by the PROP 65 warning on the packaging. California State laws are pretty stringent (and we totally support that). There are a lot of substances that we take for granted could cause harm to human beings. Wood dust is among them. Even though ökocat is practically dust free, it isn’t (and cannot possibly be) 100% so – and 99.99%, in our opinion, is just a fancy number.
Being a small company, ökocat cannot afford a California-only version and so, all their products carry the PROP 65 warning.
While on the subject of dust, if you are looking specifically for a dust free flushable cat litter, there is a Dust Free formula (which still tracks) made from paper. However, it is not as good as the clumping varieties. Only in odor control do all the different types of ökocat litter perform equally and admirably.
This is more than just one of the best flushable cat litter brands around – it is a viable alternative to clay litter.
Soft Step , made from fine wood granules, looks and feels like clay (except that Soft Step is lightweight). If you are transitioning your cat from clay clumping litter, this could be your best choice.
The official ökocat video below is informative.

In case you do not have the time, here’s a transcription:
|ökocat||Clumping Clay Litter|
|Free of harmful chemicals||Contains sodium bentonite and silica dust|
|Comes from reclaimed trees||Comes from strip mining|
|Little or no airborne dust||Powdery clay airborne dust|
Another very good cat litter made from the same ingredients as Next Gen Pet flushable litter. Hinoki, in case you are wondering, is Japanese Cypress.
Cutting down Hinoki trees so that cats can pee and poop would be a bad idea, and that is not how this litter is made. Only recycled wood from other industries (like packaging, for example) goes into the making of this natural flushable cat litter.
There is a downside which the manufacturers don’t mention (but of course!), and that is DUST. Thankfully, there is a viable solution.
All you need is to make a little effort to remove the dust with a colander. We found this solution thanks to an excellent user review. Read about it here. This is a good litter and worth the trouble, in our opinion.
Weruva masks the pee-poop odor with its own strong, woody fragrance and clumps as well as any non-clay based litter. These flushable cat litter pellets are a good choice if you are looking for any kind of natural cat litter and not just ones that can safely go down the toilet.
Note: Weruva insists that you flush in small clumps only.
World’s Best Cat Litter – super useful and charitable
World’s Best is made from whole kernel corn and 100% natural plant / wood fibers. It is safe for both septic and sewer based toilet systems. It has good odor control and clumping properties. The pine blend was created for people who might prefer that scent but the odour can be too strong for some users and their cats.
Some users mix it with other, non-scented brands of litter to lessen the scent. Wheat based litters like sWheat Scoop seem to be a popular choice. Please note, however, that the resulting mix may not be flushable.
If you have a cat suffering from kidney disease, you will need something else as superior fluid absorption is not one of World’s Best’s strong points (cats suffering from kidney diseases will invariably pee much more than usual).
World’s Best has several varieties and all of them, reportedly, show minimum dust and tracking. Bear in mind, however, ‘minimum’ is a relative term and certainly not equal to zero. But this is as far as you can come to dust-free litter that does not track (and yet is safe for your cat).
In addition to using renewable methods to manufacture biodegradable and safe litter, World’s Best also has an altruistic side which we do appreciate. Each purchase adds up to donation of litter to shelter cats. In their own words:
Cats light up your life. When you purchase World’s Best Cat Litter™, you help support GiveLitter™, and make life a little better for thousands of cats in shelters.

If you live near the coast and use a sewer based toilet system, you would be endangering marine life by flushing used cat litter down the toilet.
