1. Dr. Elsey's Premium Clumping Cat Litter

Best Flushable Cat Litter in [year]: Top 5 Brands Revealed 8
This all-natural clumping, hypoallergenic litter is free of perfumes, deodorants, and plant proteins. It promises superior odor control and a 99.9% dust-free rating. It also features heavy litter granules to avoid tracking and mess.


This all natural litter can be flushed in homes with septic tanks though you really should read instructions and warnings carefully before flushing. It is made from environment-friendly renewable wheat. The litter claims long lasting odor control and hard clumps. There is no masking fragrance and it claims to be 99.9% dust free.

The Dr. Elsey's Premium Clumping Cat Litter is a hypo-allergenic natural litter recommended for for families who suffer from allergies.


Most clients complained of price fluctuations and cheapened quality over time. Patrons who have been using this product for a long time can attest that the company's formula changed.

They also experienced the “mud” issue. If the litter that was touching the pan got wet, it created a mud-like substance that couldn't be scooped off and instead needed to be scraped, inevitably leaving small chunks of dirty litter behind.

2. Garfield Cat Litter

Best Flushable Cat Litter in [year]: Top 5 Brands Revealed 9
Made from ingredients that are 100% natural, biodegradable and plant based, this is a highly absorbent, clumping litter. It is also dust-free, gentle on paws and is flushable as well.


Here's a litter endorsed by Garfield, America's favorite flabby tabby with pets, pet parents and Mother Nature in mind. It's made with all natural plant-based ingredients that are 100% biodegradable. The clumping action is very strong, though you do have to let the clumps dissolve first before flushing.

There is absolutely no smell nor are artificial chemicals used. A combination of a lack of dust and small particles that do not track all make for a very clean litter. The light colored litter makes illness detection easier. Its consistency is much like cornmeal, meaning it will be very soft and safe on tender paws.


Let's hope your cat is colorblind. Your veterinarian might appreciate the color making it easier to examine a urine sample, but your cat may find it odd. Even though it’s natural, it is made from plant, so it’s not perfectly hypoallergenic. As stated before, the clumps are just a little too solid.

The litter must be allowed to soak and dissolve before flushing it. If allowed to sit for more than 12 hours, the clumps may become too hard to dissolve and must be discarded in the trash. The price is a bit higher for this product.

3. World's Best Cat Litter

Best Flushable Cat Litter in [year]: Top 5 Brands Revealed 10
Crafted from corn, a renewable resource that is both natural and biodegradable as well as safe to flush. It traps odors and creates good, solid clumps.


Could this litter possibly live up to its name? Here's hoping. This litter is made from corn, a renewable resource that is natural and biodegradable as well as safe to flush. It traps odors and creates good, solid clumps. Cats seem to like the fine texture of the litter. The formula is 99% dust free and comes with a money back guarantee. It is recommended for houses with multiple cats.


It is possible for corn to develop aflatoxin mold if not kept in a cool, dry place in a sealed bag or bin. It also tends to track quite a bit and there are some reviews claiming that the product is not as good at trapping odors as it advertises. The price is a bit higher for this product. As it is made of corn, if you, your cat or anyone in the family has a corn allergy, you may want to give this a miss.

4. Naturally Fresh Walnut Cat Litter

Best Flushable Cat Litter in [year]: Top 5 Brands Revealed 11
An all natural litter made from 100% walnut shells. It produces tight clumps and leaves behind a natural, fresh scent.


If you’ve bought and enjoyed products from Petco before, you may be pleased with this brand of kitty litter they produce. There is no perfume smell that might irritate your cat. The tracking is very minimal as the litter stays inside the litter box. Far more efficient in absorbency than clay litter and the odor control is excellent.

The litter is made of all natural materials and very gentle and safe to your cat’s paws and fur. This type is flushable litter and so biodegradable it can be used to compost.


It is made with walnut shells so if someone in your household has an allergy to tree nuts, you might want to give this litter a miss. While it has no perfume, it does have the natural scent of walnuts that your cat may or may not tolerate. It is dusty when pouring and your cat may enjoy the feel a little too much and decide to have some fun and play with it. The clumping ability leaves something to be desired.

5. It’s a Tea Potty!

Best Flushable Cat Litters
Uniquely made from hinoki wood and green tea. It has the property of stopping mold and bacterial growth, greatly reducing the odor It is low-dust, grain free and clay free!


Let’s give points to Weruva for coming up with a clever name for this product made with all natural materials such as green tea and hinoki wood. It efficiently neutralizes even the strongest of urine smells. It easily dissolves in water, meaning flushing is a breeze. It has none of the drawbacks of clay litter.

It is hypoallergenic without wheat, corn, soy or nut products. This litter is chemical-free and has no artificial fragrances, very little dust and tracking has been reported.


Is the pink Siamese cat on the label somewhat racially insensitive? Might have to ask an Asian person. This litter is very different from others so it may take your cat a while getting used to. You might want to try gradually introducing them to it. The particles are a bit on the big side.

While it has no artificial fragrance, it does have a natural woodsy aroma of green tea so it’s not suitable for cats who hate any sort of fragrance.

Why should you use Flushable cat litter?

Simple Disposal

So what's the big deal? It's just taking out the trash, right? Not quite. Taking out the garbage is already an onerous task. Why add some nasty cat feces to an already dirty job? It would be best to just toss it all in the toilet and let the city sewage system take care of it like it does all the nasty stuff that gets flushed away.

If you're someone who lives in an apartment building, then you definitely understand this. It can be difficult and time consuming to drag bags of garbage down several flights of stairs to the trash cans below. (Do you really wanna be That Guy who brings garbage on an elevator?)

While many apartment blocks might have a chute that you can just dump bags of garbage in, you might not be allowed to dispose of bodily waste in this manner. And even if you live on the ground floor, rain, snow and uncomfortable temperatures might make you reconsider going out to toss a couple of bags.

It's already tough to clean the litter boxes so it is best if you can get rid of the disposing of the waste part.

Don't let your cat's carbon paw print be marred by clay litter and plastic bags. Plastic bags and clay litter are not biodegradable meaning that they are not eco friendly. All they'll do for years if not centuries is clutter up a landfill where they're sure to go. After a while, those bags will just swell up and produce the most noxious of odors. Don't contribute to the crisis of growing landfills by using clay litter.

Flushable litter doesn't go to landfills. As the name suggests, is flushed down toilets and disposed just the same way human waste is processed. This helps the environment exponentially. With the best flushable cat litter, you're showing love not only to your cat, but all the fish and birds that live in the wild. After all, lynxes and cougars got to eat too and it is best for all of us if they get to live their lives unobstructed.

Disposing of the feline waste in this way is eco friendly and it helps our entire planet.

Cons of Using Flushable Cat Litter

Flushing cat litter down your pipes

image of a toilet

Unless you have the exact same pipe system the manufacturer used to test just how flushable the flushable cat litter brand you plan on using is, there is really no sure method to make an ironclad guarantee that your own toilet and pipes can handle it.

What's more, when you flush a cat litter product that expands as it absorbs moisture in cat waste, a pipe clogging is almost guaranteed.

Is flushable cat litter septic safe?

Does your home have its own septic system? That's going to make things just a little more difficult.

Even paper towels, tampons and anything cotton based can swiftly cause clogs and contamination of the entire septic system. The truth of the matter is, there does not yet exist any purely flushable cat litter septic safe product.

Safe flushable cat litter

Recently, some more environmentally friendly cat litter products have appeared on the market that are composed of biodegradable materials like pine cedar, corn cobs, wheat and paper.

In trivial amounts (other than paper) these substances might safely pass through a non-septic toilet and pipe system, although the possibility for clogs to happen in time after several incremental amounts is still present.

Nonetheless, many of these products may bear instructions to scoop only tiny amounts into the toilet at a time, and to wait nearly half an hour or more to let the material further mollify before flushing the cat litter away. So as it may be safe it also may be inconvenient.

Flushable kitty litter and Toxoplasmosis

Scientific studies have shown that Toxoplasma gondii processed through human waste treatment sites passes through unimpaired and continues to injure the surrounding ecosystem, eliminating already threatened marine life and in the end infecting people, sometimes with catastrophic results.

Best Flushable Cat Litter in [year]: Top 5 Brands Revealed 13

If you flush your cat’s waste down the toilet, you may be injecting the parasite to waterways, which may at some point wash out to the sea. Once there, toxoplasmosis could result in the deaths of endangered marine mammals such as sea otters and Hawaiian monk seals.

This parasite may not manifest if you have a strong immune system, but it could be only a matter of time. The second your immune system becomes compromised, you are at risk of T. gondii infection.

It’s logical to assume that when the waste is processed by the municipal water treatment facility, the parasites will be terminated. Unfortunately, it is a very bad idea to underestimate T. Gondii: The parasite is incredibly durable and usually makes its way through wastewater treatment completely unchanged.

State California law requires all litter manufacturers to have labels on their packages bearing a warning against flushing litter or abandoning it outdoors in gutters or storm drains.

Even if you never eject parasites into waterways through flushing, they’re apt to find their way to new hosts at some point. The parasites can continue to live for years in soil and even the coldest of water. Even if kitty does her business outdoors and buries it in natural dirt, the parasites can at some point make their way to damage marine life via rainwater runoff.

Safe flushable cat litter for indoor cats

It may cause you great relief to know that not every cat is a host for Toxoplasma gondii.

Nonetheless, this is a very common parasite and felines are the only known hosts for the beginning-stage life cycle.

You may not know if your cat carries it because most cats won’t develop symptoms.

Best Flushable Cat Litter in [year]: Top 5 Brands Revealed 14

Here are two methods that will reduce the chance your cat will be a T. gondii carrier. You should keep her indoors. You must not feed her meat that is raw or under-cooked.

Cats that live indoors at all hours and never eat raw or under-cooked meat are more likely to be free of the parasite.

Is Kitty an indoor cat? Does she never eat anything raw or undercooked?  Then there is an excellent chance that she is probably not carrying T. gondii and thus will be unable to pass the parasite into her solid waste.

Reasons NOT To Use Flushable Cat Litter

If You Are Living in Coastal Homes

If you are in a position where you live along the coast line and your drainage system is connected to the sewer, you should not use the flushable litter and flush the cat litter down the toilet. In the majority of situations, the waste will end up in the sea, and this will endanger the marine life and even cause the death of sea animals like fish and sea turtles.

Problematic Plumbing System

Is your home plumbing system is constantly failing? Then you should probably stop flushing cat litter down the toilet. You need to find an alternate solution. You should scoop the clumps in the litter and find other methods of disposal because this is not the best solution for you. Flushing the litter in the toilet could eventually block the plumbing system, and this will lead a house that smells disgusting.

State/Federal Government Regulations

Some countries have laws that prohibit disposing of flushable cat litter in the toilet. For example, in some American States, people are required to dispose of the cat litter itself since flushing it down the toilet could clog the drainage, and this might cause disastrous consequences in the time to come.

Choosing the Best Flushable Cat Litter

Type of material

image of a natural kitty litter

There are many different types of material that cat litter can be made with, each having its own advantages and disadvantages. For example, you may like the fact that natural materials like wheat and kernel corn are eco friendly but they may have a few problems concerning odor control and clumping cat litter.

To consider all the factors, cat litters made of clay have near perfect odor control and clumping but can present a problem with an abundance of dust. The dust may concern health issues like allergies when it gets into the house. It is fortuitous that some cat litter manufacturers integrate many different types of materials to bring you the best of each ingredient.


Can you really do without litter that doesn't clump? When it comes to cat litter, clumping is vital. When comparison shopping for litter, look at the reviews for best clumping litter. It goes without saying that if a litter does not clump well, the litter box and the area around it will be utter chaos.

Weak clumping ability leads to a hard time cleaning your litter box, and you don't want that so it is best if you find a litter that clumps well and works for you when it comes to other parameters described here.

Odor Control

This is the other major trait that you must always look for in whatever cat litter you buy. It does not take a genius to see how repugnant cat waste can smell. The odor from cat feces and urine is not only disgusting but unhealthy, causing health problems in both babies and adults. Because of this, you should always purchase the best kind of cat litter that can handle odors well.

Dustiness and Tracking

Best Flushable Cat Litter in [year]: Top 5 Brands Revealed 16

There are some cat litters that produce tiny airborne dust particles that can trigger an allergic reaction in you or your cat. And there’s nothing good about inhaling all that dust every day, especially for children.

You may also prefer litters that have low tracking because no one wants to see pieces of litter all around the house, the bathroom, and even furniture.
