Having a cat is one of the best things in the world.

Taking care of litter waste is a whole other matter, especially if you live in an apartment building. Fortunately, you can make the litter disposal process a lot easier. One good solution is septic safe cat litter that can be flushed.

In this article, you’ll learn everything you need to know about flushable cat litters, to see if they can be a good fit for you.

At the end, we’ll also review the five best flushable cat litter brands we found in the market

What Is Flushable Cat Litter?

As the name suggests, flushable cat litter is septic safe and can be disposed of in the toilet.

It’s usually made from biodegradable products that disintegrate in the environment. While most common litters tend to harden when mixed with water, and thus would be a nightmare for your bathroom, flushable cat litter doesn’t harden and can safely be flushed (in most cases).

Types of Flushable Cat Litter

Common (non-flushable) Cat litter is made from clay.
Clay is the most used material because it has excellent clumping properties making it a favorite among many manufacturers and cat owners.

But because of its excellent clumping properties, Clay litter could easily block your toilet and mess the plumbing system.

In addition, clay litter is usually not recommended for kittens, who may accidentally ingest some litter.

So, most flushable cat litters are made with plantbased biodegradable products like wheat, kernel corn, wood products, shredded paper, and walnutThese also tend to be safest for kittens, because if ingested they would not create issues in their little stomachs.

Corn

Corn litter is the most common among flushable cat litter products. It can either be compressed corn, whole kernel corn, or corn pulp.

Wood Products

Some products use sawdust, shavings, and reclaimed wood with no chemicals to make cat litters. Woods like pine and cedar have their fresh scents making them natural deodorizers.

Wheat

This crop can be used as a cat litter, just like corn. The starches in it clump when moisture is added, making it easy to scoop.

Shredded Paper

Cat litter brands press paper into soft pellets to make flushable cat litter. Some even recycle old papers making it eco-friendly. Baking soda is often added to aid in odor control. 

Advantages of Flushable Cat Litter

Simple Disposal

We all enjoy taking care of our cats.

What we don’t all enjoy is continuously having to take the trash out after cleaning the litter box. It’s even worse if you live in an apartment building. Dragging garbage bags down those stairs is no joke. It can be a little burdensome and time-consuming. Well, unless you are a fitness enthusiast.

With flushable cat litter, all you need to do is toss it all in the toilet. It’s that simple!

Flushable Cat Litters are more Eco-Friendly

Cat litters are usually not seen as a “green” product.

Those garbage bags we fill with waste for disposal clutter up the landfills where they end up. The results are landfills with the most noxious of odors and accumulation of toxins. To make things worse, the clay used in clay litter is extracted in ways that harm the environment.

Flushable cat litter, instead, is disposed of in the same way human waste is processed, hence having a lower environmental impact. Besides, it offers a way for kitty to reduce her carbon “paw” print.

Flushable Cat Litter is Safer for Kittens

We just mentioned that clay litter can get stuck in the plumbing system if flushed. Well, what do you think would happen if your cat accidentally ingests it (which can happen)? The answer is not pretty.

Let’s just say that because kittens tend to accidentally swallow more things, it is usually recommended to not give them any clay or crystal litter until they are at least six months old. The best solution?
You guessed it. Flushable Litter! It is the most natural and safest option.

As always, in matters of health and safety, it is best to check with your vet for further recommendations.

Disadvantages of Flushable Litter

Not Ideal For All Septic Systems

Do you perhaps have a septic tank? That can make things a little more complicated. Most flushable cat litters are not designed for working efficiently with a septic tank. 

With septic systems, flushing litter can clog up toilets the same way like paper towels and anything cotton based. Many manufacturers advise flushing a small amount at a time and allowing it to settle before flushing. This process is time inconvenient even though it could eliminate the toilet blocks.

Can Introduce Parasites Into The Waterways

Flushing kitty litter down the drain could expose water channels to parasites.

Toxoplasma gondii is a harmful parasite that can be found in cat poop. This parasite can go through the waste treatment sites and end up in water.

In this way, T.gondii poses a high risk to people and already endangered marine life like sea otters and seals.

When Should I Not Use Flushable Cat Litter?

If Living In Coastal Homes

Cat litter can adversely impact the ocean the same way it does for modern waterways. It’s advisable not to flush cat litter if you live along a coastline and are connected to the sewer. Often, the litter ends up in the ocean exposing marine life to toxins and harmful parasites.

State/Federal Regulations

Some states like California have imposed strict rules against flushing cat litter. The government even requires manufacturers to clearly label their packages with warnings against flushing litter.

Make sure to research local laws concerning litter disposal before purchasing a flushable cat litter.

Factors To Consider When Choosing The Best Flushable Cat Litter

Odor Control

There is more to picking the right cat litter than just how flushable it is.

Cat waste can smell. The stench from cat urine and poop is both unhealthy and unpleasant. A suitable cat litter should be able to handle the odors well. If you’re particularly interested in containing bad smell, we recommend checking out our full guide on the best cat litter for odor control.

Clumping Or Non-Clumping?

It’s all a matter of preference. Clumping cat litter is a favorite among pet parents. It eases litter box cleaning and keeps the area around the box clean.

Most flushable cat litter does not clump as well as clay litter. But there are also good flushable clumping cat litters in the market.

Dust And Tracking

Some cat litters are dusty and cause allergic reactions to both you and the sensitive kitty.

In general, flushable cat litters tend to be low dust and low tracking compared to clay. Still there might be considerable difference among different flushable products. If you’re particularly interested in low tracking litter, check out our full guide and review of the best non tracking cat litter and of top entry litter boxes (which are great at containing tracking).

Look out for dust-free litter in the product description. Also, I recommend litters with low tracking. Well, unless you want to constantly see pieces of debris all around the house.

How Do I Know If My Litter Is Flushable?

If it is flushable, it would be clearly stated on the package. Do not try to flush a litter whose package does not clearly say that it’s flushable.

Many cat owners assume that all-natural or biodegradable litter is flushable. Please pay attention to the packaging and ascertain that it’s flushable before pouring it down the drain.

This is a great example of a natural, paper-based cat litter that is not flushable.

Watch out for silica litter, also known as crystal litter, as it expands within the pipe as it comes into contact with water, creating huge issues for your septic system.

Is Flushable Cat Litter Safe For Plumbing?

Not all cat litter that is advertised as flushable is suitable for your pipe system. It can still clog up the pipes and cause plumbing problems.

I prefer going through the instructions and product information before disposing of litter in the toilet.

To be safe, it’d also be advisable to flush a small amount at a time, allowing the litter to settle before flushing.

Is your plumbing system continually failing? You should then probably find an alternate mode of disposal to avoid unwanted plumbing headaches.
