Best Flushable Cat Litter

Cats are great pets, but owning one and deciding to keep it indoors, however, could be stressful for the cat and its owner.

Unlike outdoor cat owners who do not have to worry about having a litter, indoor cat owners have to go through the daily task of having a litter, keeping it clean and then disposing of it.

Not doing so will only cause serious health problems for both the cat and the household. No one likes to walk into, leave alone using a dirty toilet. In the same way, no cat will like to walk into and use a dirty litter box.

What are Flushable Cat Litters?

Litters made with recyclable materials are classified as flushable cat litters. These are natural, organic and easy to flush. Also, not all cat litters are flushable and so the ones that can be flushed are grouped separately.

Not only are these eco-friendly and completely renewable, but they also help maintain the cat’s overall health and wellness. Typically, flushable litters are dust-free, synthetic-free, chemical-free and fragrance-free.

The general materials used to formulate flushable cat litter include corn, walnut shells, recycled paper products, pine pellets, wheat by-products, grass, wood, sawdust, and citrus, all of which offer varying level of effectiveness in different aspects. Moreover, some of these materials can be used as fertilizer, mulched or incinerated.

Flushable cat litter makes your litter disposal routine easier and more convenient. All you have to do is toss the litter in the toilet, flush it and forget about it.  However, flushable litter isn’t perfect and doesn’t make the process entirely effortless.

Why Should We Go For Flushable Cat Litters?

Cat wastes are biodegradable but the cat litter product that they deposit these wastes into may not necessarily be biodegradable. So leaving them around for a very long time could have very harmful effects on our environment. Besides, how long do you want to keep disposing of your cat’s wastes in the trash can or in a hole in your backyard?

But Flushable Cat Litter is not Perfect.

Pros & Cons of Using Flushable Cat Litters:

There are plenty of reasons for cat owners to use flushable cat litters. Some of them are shown below:

  • Ease

With flushable cat litter, your worry about disposing of your cat’s wastes disappears. That’s because the time consumed in packing up the smelly wastes and dragging it outside is saved. Also, the inconvenience caused during unfavorable weather conditions is minimized.

  • Environmental benefits

If you love your environment as much as you love your cat, keeping them both safe should be on our mind while buying a cat litter. That’s because it does not do the earth any good when we dump cat litter mixed with solid waste. This gets even worse when you use disposable litter trays. All of this would eventually pile up a lot of waste, and that too really fast. Therefore, flushing your used cat litter down the toilet reduces landfill waste, air pollution, and environmental degradation. As a result, the cat litter becomes biodegradable and it also saves space. Cat litter, being a major contributor to landfill waste, can be treated like a human waste by flushing it down the toilet.

  • They are Hypoallergenic

Flushable cat litters are usually hypoallergenic. This means you and your cats don’t have to worry about allergic reactions.

On the flipside, there are also some cons of using flushable cat litters:

  • Introduces parasites to waterways

Domesticated cats and other members of the cat family commonly carry a parasitic organism known as Toxoplasma gondii.  So, flushing the litter of an infected cat into the waterways could eventually carry it to the sea.  Since parasites can survive in soil as well as cold water, they can eventually infect others.

  • Causes clogs

There is no guarantee that flushable cat litter will pass through your plumbing smoothly without causing clogs, especially in older or rusted pipes.  These clogs could have very unpleasant consequences, some of which are, inability to flush and spending on repairs. It is advisable to dump the litter gradually into the toilet and then let it break down in the water for a while before flushing it.

  • Stains

Some cat litters made from abrasive materials like walnut could cause scratches on the surface of your toilet bowl. Apart from the stains, the litter could also damage to your toilet’s bowl. Therefore, even the flushable cat litters require a lot of precautions and thorough cleanups.

  • Toxic substances

Materials used in some flushable cat litters may lead to the growth of toxic molds called aflatoxins when exposed to moisture. The chances of this happening are a lot higher in cereal-based litters like the ones that contain corn and wheat.
