Why Use Flushable Cat Litter?

According to a report by Stanford University, billions of cat litter is dumped in landfills annually, and this leads to contamination of water sources. In fact, the amount of cat litter dumped in landfills is 15 times more than the number of human diapers. Such cat litters tend to swell and stick when soiled and are harmful to the environment.

The use of flushable cat litter is a well-thought-out alternative that gives you a piece of mind and lets you dispose of cat litter without harming the environment. Once the litter is drained in the toilet, it is treated like human waste to make it safe for the environment.

The treatment removes harmful components that may be present in the litter, making the waste biodegradable. The United States Environmental Protection Agency (US EPA) recommend flushing cat litter as opposed to dumping it in landfills.

Flushable cat litter is made of natural materials such as kernel corn and wheat that are biodegradable. Also, use of these materials helps in absorbing the wastes and reducing odors, that may be caused by ammonia in the cat urine.

You are Setting up the Litter Box the Wrong Way and the Solution

When NOT to Use Flushable Cat Litter

Although using the best flushable cat litter is recommended, there are instances where cat owners are advised not to use flushable cat litter. Such situations include:

Living in Coastal Homes

In a situation where you live along the coast line, and your drainage system is connected to the sewer, you should avoid flushing the cat litter down the toilet. In most cases, the waste will end up in the sea, and this will harm the marine life and even lead to the death of sea animals like fish and sea turtles.

Faulty Plumbing System

If your home plumbing system is defective, you should stop flushing cat litter down the toilet. Instead, you should scoop the clumps in the litter and find alternative disposal methods. Flushing the litter in the toilet may end up blocking the plumbing system, and this will lead a foul smell within the house.

State/Federal Government Regulations

Some countries have laws prohibiting the disposal of cat litter in the toilet. For example, in some States in the United States, people are required to throw the cat litter itself since flushing them down the toilet could clog the drainage, and this might lead to drastic consequences in the future.

What to Consider when Buying Flushable Cat Litter

If you are a recent cat owner or an experienced cat owner looking to buy a new type of cat litter, there are some factors that you should take into account. Here are some of the things that you should consider when looking to buy the best flushable cat litter:

Type of material

The various types of flushable cat litter are made of different materials, each having its advantages and disadvantages. For example, natural materials like wheat and kernel corn are generally good but may have a few problems with odor control and clumping.

On the other hand, cat litters made of clay have excellent odor control and clumping but can be a little dusty. The dust may have health issues like allergy when it gets around the house. In some cases, some cat litter manufacturers combine several types of materials to bring the benefits of each ingredient.

How Messy is it?

Some cat litters are less messy than others, depending on the materials used. In determining how messy a litter is, we consider water retention, dust levels, and tracking.

  • Water retention capability- A good flushable cat litter should be able to retain urine and feces and keep the litter dry. It should absorb moisture before it gets to the bottom of the litter box.
  • Dust levels- A good flushable cat litter should have proper dust control mechanisms to avoid exposing the cat and people living around to health issues. The dust from cat litter can lead to harmful allergens.
  • Tracking- Tracking is when the cat carries the litter granules out of the litter box on its paws. For a litter that tracks often, you will be required to clean the house regularly. A good flushable cat litter should track as little as possible at all times.

Clumping

Clumping is when the cat litter forms around the cat droppings, making it possible to scoop out the area where the cat excreted. When buying a flushable cat litter, you should check to confirm if the litter is a clumping or non-clumping cat litter. Although some cat owners prefer clumping cat litter, there are others who prefer non-clumping litter.

If you are not sure which one to choose, the clumping cat litter is more convenient since you can scoop out a particular area where the cat dropped its poop. This will be more economical in the long run since you will not need to dispose of the entire litter. Additionally, clumping helps in minimizing the odor from the urine and poop.

Size of granules

Cat litter granules come in different sizes, and it is important to find the right balance that your cat will love. Finer granules will be softer to the cat toes, especially if you just de-clawed your cat or you have kittens around.

However, the problem with fine granules is that they track easily and you will need to do frequent cleaning. You should go with fine-textured granules that track as little as possible.

Conclusion

From the Top 5 Flushable Cat litter Reviews and the considerations that you should make when choosing a flushable cat litter, you should be in a position to choose a litter that your cat will love. In some cases, cats can be very picky, and you are likely to test several cat litter brands before you find one that the cat is comfortable with.

Regarding Dr. Elsey’s Precious Cat Ultra Premium Clumping Cat Litter (Best Seller) as a flushable cat litter, all the replies to questions on Amazon about “flushability” indicate it is NOT flushable. Who is correct?

Hello. Thanks for your informative site! I am looking for a flushable cat litter only bc my cat must have radioactive iodine treatment for his thyroid tomorrow. His urine & feces may contain traces of radioactive iodine for 2 weeks & should not come into contact w/my other cats.

The Dr. Elsey’s Cat Ultra Premium Clumping Cat Litter linked above is not flushable. According to their website, none of their litters is flushable & no clumping litter should be flushed. https://www.drelseys.com/about/faqs/

My only other option may be to keep his used litter, urine & fecal matter in the garage or backyard for 2 weeks. 🙁
