What is Flushable Cat Litter?

Flushable cat litter, as the name indicates, can be flushed in the toilet, which is not the case with conventional clay-based or silica-based litters.

Being biodegradable, flushable cat litter won’t harm the fish and other creatures in our waterways. It can also be composted since it is made of natural, food-grade materials.

Flushable cat litter is typically made of soyabean, paper, pea fibers, wheat grain, corn, cornstarch, cassava, wood, etc.

This litter can ease the cleanup process for cat parents. Also, being food-grade, it is safe for cats if your pet accidentally ingests it. (It is still a good idea not to let your cat eat the litter otherwise it can cause allergies or excess weight gain!).

What are the Different Types of Flushable Cat Litters Available?

You can get the following types of flushable cat litters:

A) Grain-based

These contain either wheat or corn kernels. These are all-natural food-grade, and completely compostable and biodegradable.

Depending on the manufacturing process, you can get 100% dust-free grain litters.

B) Vegetable-based

These include pea fiber and soybean/tofu litter. They have superior absorbency and are 100% compostable, flushable, and safe-even if ingested by a pet. (Note that these foods are common allergens so do not allow your pet to eat them.)

These litters also have low dust and low-tracking – depending on their manufacturing process.

C) Wood

Certain types of wood-based litters are also flushable.

These include pine, cedarwood, and wood shavings. However, always make sure that the product labels clearly state that the litter is flushable in order to avoid clogging of your septic system.

D) Paper-based

Cat litter made from recycled and shredded paper is also biodegradable and flushable at times. Manufacturers may add enzymes, activated charcoal, or baking soda to make enhance the litter’s odor-absorption property.

What are the Pros and Cons of Flushable Cat Litter?


Good for the environment

As the litters are made from recycled materials, food-grade ingredients, and all-natural materials, they are better for the environment as compared to non-flushable/clay litters.

These litters can be composted and they biodegrade easily. This way, they do not harm our over-burdened landfills.

Compostable biodegradable cat litters also help plants grow. Flushable litters are safe and non-toxic so they do not harm wildlife.

In short: the best flushable cat litter is sustainable and 100% ‘great’ for pets and the planet.

Safe and non-toxic for humans and pets

High-quality flushable cat litter is made of food-grade materials.

Depending on their manufacturing process, the litter is also free from dust. This reduces allergies in sensitive cats and humans.

Food-grade flushable litter can even be ingested by cats without causing any harm.

Easy to clean for pet parents

The flush-ability feature eases cleanup for cat parents as one simply has to toss out the litter.

Being lighter in weight than clay litters, it is also easy to carry out.


Might not clump well

Many flushable litters do not really clump as quickly and properly as traditional clay-based clumping litters do.

The downside to this is that you still need to scoop out the mess which could end up wasting a lot of unused litter as well.


Many flushable litters are quite expensive. They often come in small bags and need special packaging to prevent them from crumbling during transport.

All these factors could increase their price. This is the reason why some multi-cat households do not find these litters affordable and economical.

Plumbing and toxin concerns

Cat feces contain bacteria and viruses. When these enter our waterways through the flushable litter, they can be harmful to the fauna.

Also, some of the so-called flushable litters could still create a clogged mess in the plumbing pipes and the septic tanks. That is why, some plumbers advise against flushing cat litter even if the product claims otherwise.

Many state governments in USA do not allow flushing of cat litter as well to protect wildlife.

What Features Should You Consider When Selecting the Best Flushable Cat Litter?

1) It is made from natural, biodegradable materials

Always read the product labels.

Make sure that the main ingredients in the litter are safe to compost – which could mean that they are also safe for our water ways.

The label should also state that it is safe for flushing and 100% safe for the septic tanks.

Look for materials like corn, soyabean, pea, paper, wood, or wheat etc. along with natural odor control like activated charcoal and/or baking soda. Do make sure that the product is obtained from sustainable resources and is good for the environment and safe for pets.

2) Your local regulations allow it

Some states and cities prohibit the use of flushable litter to protect the wildlife.

Avoid using litter products that are prohibited for sale in your state/city.

3) Your cat approves of it

Cats can be very finicky when it comes to litter changes.

If your cat has been used to traditional litter all its life, changing to flushable all of a sudden can be difficult for it to adjust to. Allow some time for this transition – start slow. Add a small quantity of the new litter to its old litter.

Make sure your cat does not start eating the ‘tasty’ corn or pea fibers.

Observe your cat for a few days for any litter box behavioral issues. If none arise and your cat shows signs of liking the flushable litter, then you can safely make the complete switch.

4) Does not track and is low in dust

As with any litter, this is an important feature to consider.

You do not want litter that is tracked all around the house. It should also have a low-dust (zero dust, ideally) formula that won’t irritate humans and pets.

5) Offers superior odor control

Look for flushable litter that has a high absorbency rate to eliminate pee and poo odors. It need not be harshly scented (which could irritate your cat) but it should ideally make your home smell fresh and clean.

6) Economical

Your budget will play an important role when selecting the best flushable cat litter. Look for a product that is economical and long-lasting so that a small bag goes a long way. This is especially the case if you have multiple cats. 


The best flushable cat litter are safe to go down the drain and make cleanup easier. They are also good for our pets and our planet.

We recommend the World’s Best Cat Litter as it is made from eco-friendly corn kernels and is 100% flushable, biodegradable, and septic tank safe. The brand has extensively tested this litter to ensure it won’t clog toilets.
