Best Flushable Cat Litter: Top Eight Options To Consider

Best flushable cat litter

Flushable cat litter is an alternative to the traditional clay cat litter that is made from sodium bentonite. This traditional litter has been used for years because it is highly absorbent, convenient, and fairly clean. However, people are now looking for alternatives to this dense and heavy litter. One reason why flushable cat litter is on the rise is because of the lack of plastic bags that you get every week at the market. Since we have to take our own bags, we don’t get those convenient plastic throw away bags anymore. This has led to a much more environmentally friendly way of disposing of our cat’s waste through flushing it down the same septic system we flush our waste. However, you can not do this with the traditional clay cat litter because that would do nothing but clog up your pipes. This is why it is important to find litter that actually is flushable before you have to pay a very expensive plumber bill.

Types of Flushable Litter

As we mentioned that traditional clay litter won’t work for flushing down your toilet, you may be asking what flushable litter is made out of. The best flushable cat litter are made out of natural ingredients such as newspaper, corn, wheat, or wood. These products are generally safe to be flushed down the toilet. If you are connected to a septic system instead of a sewer, you will need to double check if each different product is acceptable to be flushed into your septic tank, but for the rest of us on a sewer system, these products are all acceptable for our toilets. The flushable cat litter made out of products such as newspaper, corn, wheat, or wood also comes in different textures and formulas. For example, these different textures and formulas are important if you want a finer litter in comparison to the pellets, or if you want litter for a single cat house in comparison to a multi-cat home.

Benefits of Flushable Litter

Being able to flush your cat’s waste down the toilet rather than having to collect it and put it in your garbage can is not the only benefit of flushable litter. These litters don’t have that familiar dust cloud that traditional litters do when you pour them into your cat’s litter box. This means there is less dust when you are cleaning the box, and less dust for your cat to track all around your house. They still clump which makes it easier to clean the litter box and keeps your cat happier. In addition, they do a good job of neutralizing the odor. Flushable cat litters are also biodegradable which makes our environmentally conscious friends happy.

What About the Downsides?

You may have seen warnings on bags of litter before, warning users of the dangers of flushing it down the drain because it has the potential to spread the parasite Toxoplasma Gondii. Cats are common carriers of T. Gondii, which can be a danger to immunosuppressed people like those with severe illnesses or pregnant women. This parasite is not killed during treatment at a water treatment facility and could kill infect the water or even kill endangered sea creatures.

This may sound horrible, but first of all not every cat is infected, and secondly some have noted that even buried fecal matter would not get rid of the parasites because it would still make its way into the water runoff, so whether you flush your cat’s waste, or they bury it outside, it still has the same potential.

Another downside is that flushable litter has the potential to actually damage your toilet bowl. Due to its abrasive nature, it could scratch the surface of your bowl and lead to the eventual wearing away of your toilet bowl’s white covering. It could also stain the inside of your toilet bowl if you use products that are darker in color.

A final issue that you need to be aware of is that flushable litter is not always as simple as it sounds. The clumps of litter can clog your pipes even though they are made of biodegradable products that are acceptable to be flushed down the drain. It is important that you let the clumps break down in your toilet bowl a little bit first before you flush them. This also becomes an issue when you are dumping out your cat box in order to clean it. You can’t just easily dump the whole box into your toilet because that would lead to major clogs in your pipes. This means that it takes a little bit longer every time you need to clean your cat’s box because it is not as simple as pouring out the litter and replacing it.
