What Is Flushable Cat Litter?

Flushable cat litter is essentially cat litter that is both safe for your home and the same for the environment to flush down the toilet. In this article, we will discuss some of the best flushable litter brands on the market and why it’s so important to pick the right brand.

Don’t you ever wish you could flush away your cat’s litter?

Typical clumping clay cat litter is usually made from sodium bentonite. It is the same natural clay that is often used for plugging holes and sealing ponds and landfills. This highly absorbent clay expands 16-18 times its original size when dampened.

The cement-like material formed by sodium bentonite clay and water can block pipes with a clog or cause severe damage to your septic system. So, that’s not the items you want to flush. These high absorbent qualities make clumping clay litter a convenient and clean favourite among humans and cats alike.

If you want to flush your cat’s litter, you must need a septic-safe alternative that works for your home-plumbing and the environment.

Why is flushable cat litter so good?

Especially for people who live in small apartment buildings or collect trash for weekly trips, bags of used litter can become a high frustration source. You often don’t recognize how dense cat waste and litter are? Until you have to pick a stretching, full dirty cat litter garbage bag up or down the stairs.

In terms of environmental impact, flushable litter does not require plastic bags, and you don’t need to send your cat litter to the landfill. Instead, the waste is cleanly and properly flushed away to the same septic tank or treatment facility that handles our waste.

But all flushable cat litters are not so good as it seems. (Except our Selection)

Flushable cat litters have three main problems:

  • Toxoplasma Gondi
  • Didn’t pass smoothly from plumbing
  • Damage your toilet bowl

We discuss them later on in this article, but here we want to give you the Top six best flushable cat litters in the market that are free from all three problems mentioned above.

What is Toxoplasma Gondii?

Toxoplasma Gondii is a parasitic microorganism that can infect any mammal, especially cats. Domesticated cats and other members of the feline family are common carriers of this parasite.

When infected with this, cats shed hundreds of thousands of eggs through their stools/faeces. While infected humans usually don’t have any apparent symptoms, it can cause serious illness in immune-compromised people. Pregnant women are mainly at risk because they may pass the infection to their fetus and lead to abortion.

That’s why it’s always suggested that pregnant women avoid cleaning the cat litter box. It is also the primary cause of abortion in underdeveloped countries.

By the process of flushing your cat’s waste down the toilet, you ultimately increase the chances of this parasite to waterways, which may eventually route it to the ocean.

Once there, Toxoplasma Gondii could cause the deaths of Hawaiian monk seals, endangered sea otters, and other marine mammals by causing toxoplasmosis.

It’s reasonable to theorize that the parasites will be killed when the waste passes through the municipal water treatment facility. But if you believe that, you’ve underestimated Toxoplasma Gondii because this parasite is incredibly hardy and usually passes through wastewater treatment unharmed.

California and New York require all litter manufacturer companies to label their packages with a warning sign against flushing litter or disposing of it openly in storm drain or gutters.

Even if you don’t ever introduce T. Gondii to waterways through flushing, they’ll most probably find their way to new hosts sooner or later. This lethal parasite can survive for many years in cold water and soil; even the parasites in faeces buried in the ground can subsequently make their way to sea mammals via rainwater drainage.

Why It’s Important To Use The Correct Flushable Cat Litter:

Any cheap flushable cat litter never give you the guarantee to pass through your plumbing smoothly. In fact, it could cause clogs everywhere. This is an alarming condition and happens most often if your pipes are older.

It’s an excellent idea to let the litter soak in the water for a little time before flushing it. Go slowly and never dump large amounts of litter into the toilet at once.

Any clumping litter might stick to grease present in plumbing or attach to any other buildup in your pipes with very unpleasant outcomes.

Another thing important to consider is that cheap flushable cat litter could damage your toilet bowl very quickly.

More abrasive chemicals present in cat litter could scratch the surface, and staining is another possible issue. If you choose a dark-coloured cat litter, e.g., walnut litter, it might stain your toilet bowl from inside.

Lastly, tossing a boxful of cat litter into the toilet isn’t as easy as pouring any other contents and forgetting them. It’s not a good idea to dump a complete litter box full of cat litter into the toilet.

There are an absolute convenience and easy unobtrusiveness about the act of flushing cat litter down the toilet, but it will never make the job easy.

Types of Flushable Cat Litter:

The most acceptable flushable cat litter has been tested multiple times and approved by FAO and municipal organizations for septic and sewer systems.

If you aren’t connected to a central city sewer system and use a septic system of your own, it’s essential to ensure that the litter is approved for your situation.
