Which types of Cat Litter are Safe to Flush?

As much as we would like them to be, not all cat litters are flushable. DO NOT EVER flush standard clumping clay litter as it contains sodium bentonite, which is used to plug holes and seal landfills. 

This clay expands up to several times its original size and forms a cement-like compound, as soon as it comes in contact with water. 

Sodium bentonite will 100% block the pipes and damage the septic system. Clogged toilets are way worse than cleaning your kitty’s poo.

Why use a Flushable Cat Litter?

Yes, flushable cat litter makes life easier for us all cat owners. It is especially good for apartment dwellers, who have to build up trash and get rid of it on a weekly basis. But there is more to the story. 

Flushable cat litter offers several other benefits, which make it a huge favorite among several cat parents. 

Flushable cat litter is made from natural materials and reduces the smell of cat urine and poo. The waste is disposed of immediately so you don’t have to worry about the stench coming from the litter tray. 

But the best part making me a HUGE flushable cat litter fan is its minimal impact on the environment. It prevents your furry feline’s paws from leaving huge carbon prints. 


You no longer need plastic bags to dispose of used litter. It won’t be sent to landfills where it would clutter up for years. Moreover, the waste is flushed away to the same septic tank or sewage system that handles human waste. It is far more hygienic this way.

In case you have inquisitive kids, flushable cat litter is the safest option. And it safeguards your household from the nuisance of cat litter attracting insects during the summers. There would be no smell, hence no unwanted visitors!

Drawbacks of Flushable Cat Litter

There is nothing like 100% benefits in life. Flushable cat litter makes life easier and is good for the environment but it has potential drawbacks you should know about. 

The biggest potential threat comes from the possibility of flushable cat litter polluting the waterways with Toxoplasma Gondii. If your cat is infected from this parasite and you flush down the litter, the parasite will find its way into the waterways. 

Research has shown that this parasite is capable of passing through human waste management and treatment plants unscathed. It is a direct threat to marine animals like sea otters and can also infect humans. 

Pregnant women are at more risk of getting toxoplasmosis Gondii infection. It can be detrimental for developing fetuses. 

Flushable cat litter companies do not provide a 100% guarantee that the litter would pass through drains. If you are flushing down lots of litter at once - particularly the one that expands on absorbing moisture- it can clog your toilet pipes. 

You have to be very careful while using this on older pipeline systems. They are more prone to clogging.

The best way to ensure flushable cat litter works well is by introducing the litter gradually to your septic system. This way you won’t overwhelm the system and any warning sign can be seen right in the starting before the matter goes out of hand. 

You will also find that litter can stick to grease in pipes and if you are not flushing satisfactorily, it can build up. Some litters also stain the toilet. The best way to avoid all of these problems is by flushing used litter in several flushes. Do not try to get rid of it all in one big dump load.

Types of Flushable Cat Litter

There are several brands selling flushable cat litter. Clogged toilets can drain a lot of money in repairs, so your best bet is to only buy flushable litter from brands that have tested and approved it for septic and sewer systems. 

There is one thing universal for all flushable cat litters - they do not contain sodium bentonite clay. Generally, natural and biodegradable litters are flushable You can pick up a clumping or non-clumping type as per your preference. 


However, a word of caution here. Some natural litters can clog your pipes if they expand several times up to their size on absorbing mixture. Remember to read the label carefully and see if the brand mentions the litter is safe for sewer and septic tanks. 

Flushable cat litters are commonly made of corn, newspaper, wood, and wheat. Such litters will have different textures and water-absorbing properties depending upon their formula.

Now, let’s delve further into the world of flushable cat litters and discuss the 7 best flushable cat litters of 2020.

7 Best Flushable Cat Litters of 2021

1. World's Best Cat Litter - Best Overall Flushable Cat Litter Option

I’ll be honest. The first thing I look for in a flushable cat litter is its odor control properties. My cat is extremely picky and if the litter has any unnatural smell or even an artificial scent, she just refuses to do her business. 

I have tried several kitty litters in the past and some of them absolutely fell flat on their odor control claim. The area would reek of cat piss. Personally, I feel World’s Best Cat Litter stands strong on its claims. 

I would recommend it to people who want a flushable, septic tank safe, unscented, and odor-controlling cat litter. If you or your kitty are allergic to silica dust, this might be a good pick. The brand claims to be 99% dust-free and lightweight. 

If you are a proud mom to several furry felines, this flushable cat litter might save you from a lot of labor. It is quick-clumping, which makes it easier to scoop. You won’t need to chisel or scoop. Ain’t that wonderful?  At least your back will thank you. 

Cats with sensitivity issues might adapt really well to World’s Best flushable cat litter, as it is made from whole-kernel corns. There are no artificial perfumes or harmful chemicals.  

Several cat owners have expressed their satisfaction over the quality offered by the brand. Some have even called odor control ‘phenomenal’. Few customers did express concerns about clumps falling apart.
