The Lowdown on Flushable Cat Litter Products

Choosing the right cat litter helps to ensure a clean, comfortable and odor-free environment for you and your cat.

But given how saturated (pardon the pun) the market has become, this is often easier said than done.

One of the products that have really started to proliferate in recent years is flushable cat litter.

Heralded as being convenient and eco-friendly, flushable litter products have become a very popular option among owners.

But just how effective are these products.

This guide offers the dirt, so to speak, on flushable cat litters, evaluating the different brands and some of the qualities to look out for.

First of all, are these products really flushable?

Is Flushable Cat Litter Really Flushable?

While flushable cat litter is supposed to be safe to flush down the toilet, this isn’t always the case.

Made from biodegradable materials, it’s designed to break down more easily than traditional products.

But whether it’s truly flushable depends on a number of factors.

Plumbing System

Older or weaker plumbing systems may struggle to handle flushable cat litters due to narrower pipes.

Blockages are often the result which can put pressure on the pipes’ seals and joints.

In certain instances, there’ll already be a build up of sediment and debris which increases the chances of a blockage.

Septic System Compatibility

If your home has a septic system, make sure the flushable cat litter is specifically labelled as septic-safe.

Clumping flushable cat litter products won’t break down properly in septic tanks and can cause blockages.

Additionally, even biodegradable products can decompose slower that the rate at which waste is processed in the septic tank.

As a consequence, the resulting accumulation of litter in the tank can disrupt the system’s bacterial ecosystem.

Toxoplasmosis Concerns

Cat feces can contain a parasite called Toxoplasma Gondii that causes a disease known as toxoplasmosis.

Flushing cat feces down the toilet can potentially introduce this parasite into the water supply.

Although rarely fatal, toxoplasmosis can present a significant risk to pregnant women and those with weak immune systems.

While flushable cat litter may be safe to flush, it’s essential to weigh the risks before making a decision.

When in doubt, dispose of used cat litter in the trash.
