Flushable Cat Litter: What is It

What is flushable cat litter? If you read descriptions of different brands, you will not find a clear classification. For example, is Fresh Results corncob cat litter flushable or not? You may find controversial opinions.

Basically, any cat litter that can be flushed without causing damage to both the toilet bowl and the sewer system can be treated as flushable. It doesn’t form jams in waterways and doesn’t prevent the normal functioning of the sewerage system. It can be made of different materials, predominantly natural. If compared to clumping clay litter, it has some advantages and certain disadvantages.

On the plus side, flushable cat litter removes the necessity in regular disposing of heavy bags with expended clumping litter. Flushing is a fast and convenient method of utilization. It is affordable and won’t make a hole in the family budget while cats commonly love it.

That said, there are certain disadvantages as well. Cats’ parasites that are transmitted with feces can get into the sewer or the septic system and via waterways get to rivers and seas. Some species of sea mammals are prone to infecting with Toxoplasma Gondii. The second disadvantage is that despite being not as hard as clay litter, even the best flushable cat litter can contain abrasive components that can scratch the toilet bowl. Finally, the risk of clogging still remains – to avoid it you need to put litter in the bowl and flush it in small portions.

Types of Flushable Cat Litter

First and foremost, it’s important to understand what cat litter is flushable. Commonly, it is assumed that any litter that doesn’t contain sodium bentonite clay is flushable. It means that it comes in a variety of materials, types, and textures. In particular, flushable cat litter can be:

  • clumping or non-clumping;
  • made of wood pellets or sawdust, corn, walnut, wheat;
  • coarse- or fine-grained;
  • scented or neutral (unscented).

When choosing the cat litter, you need to decide on its type. It’s important to choose the right texture and material that will be to your cat’s taste, effectively eliminate or absorb odors and won’t damage the sewer system. In our article, we are going to review flushable cat litter brands and try to choose the best of the best ones.

Advantages of Flushable Cat Litter

There are several reasons to choose flushable litter. Apart from its convenience, it has some important advantages over conventional clumping clay litter. Here are its main characteristics that make it a preferable choice.

  • Environmentally friendly. Flushable litter is commonly made of organic components – wood, wheat starch, cassava, corn. Unlike synthetic litter, it is eco-friendly and doesn’t pollute the environment. And you don’t need disposable plastic bags to throw it away.
  • No clumping on cats’ paws. Clay litter tends to stick to paws, resulting in a mess around the litterbox and around the home.
  • No irritating scent. You can flush the used litter as often as you wish. Even if you forgot to clean the litterbox, it will absorb unpleasant odors. The quality of absorption depends on the type and quality of the material.

Things to Consider When Choosing Flushable Litter

With many sorts, types, and brands of flushable litter, it is important to choose the right products that meet your needs best. Here are the main things to consider.

Septic System

One needs to understand that not all types of flushable litter are septic-safe, though most of them are sewer-safe. This information is commonly available in the product’s specs list or description. It is crucial to choose the type of product that is approved for your septic system.


Clumping characteristics of various types of litter can vary. Non-clumping materials are more difficult to clean and tend to stick to the litterbox and spill around it. That said, some kinds of litter form very hard clumps that need to be dissolved in the water or broken before flushing. Try to avoid such materials is you don’t want to spend hours near the toilet boil waiting for the clumps to dissolve.

Odor Control

The odor of cat urine is very sustainable and long-lasting. It is almost impossible to get rid of it completely: flavored litter masks the odor but it neither prevents nor eliminates it. That is why try to choose non-flavored products made of materials that quickly absorb liquids and lock the odor inside the clumps.

Dustiness and Tracking

Some types of litter (wooden pellets, zeolite) are really dusty, despite being effective and economic. If you want to reduce the amount of dust in the home and prevent tracking, choose dust-free options. A good example is granules made of recycled paper.

Five Amazing Facts about Cat Litter Boxes

A cat in a litterbox

  1. The first modern cat litterbox was created in 1948. At first, litterboxes were filled with sand, which was later replaced by clay.
  2. The number of litterboxes in the home must be equal to the number of cats you have. Cats hate sharing their toilet with anyone.
  3. Cats are finicky and they hate when a litterbox is placed near the place where they eat. Try to place it in another room, or, at least, in the opposite corner of the room.
  4. Try to find a hidden place for a litterbox. Cats need privacy when they make their toilet deeds.

5. Contrary to a popular belief, cats don’t see in the dark. Don’t place a litterbox into a lightless corner.

Simple Rules of Cat Litterbox Maintenance

You must be aware of the fact that cats are very tidy animals. That is why regular scooping and cleaning of a litterbox is crucial even if you use the best clumping flushable cat litter that blocks the odor. Here are some basic tips on how to maintain cat litterboxes correctly.

Scoop Daily

If you use clumping litter, scoop the new clumps 1-2 times a day even if there is no odor. After scooping, add some clean litter to maintain the level 3-4 inches in the litterbox. Keep in mind that cats are fastidious, and if the litterbox is not clean enough, they can start pooping outside it. The same is about feces: it should be disposed of immediately or, at least, once a day, if you are away all day long.

Change Litter Once a Week

No matter how often you scoop the clumps, you should change the litter every week. Empty it out of the litterbox and wash the latter with warm water with a toilet bowl cleaner or another type of cleaner. But try not to use chlorine: most cats don’t like how it smells. Let the litterbox dry and fill it with a recommended amount of fresh litter.

Change the Litterbox Every Half a Year

If you use a conventional plastic litterbox, you need to change it from time to time. The fact is that the odor of cat urine is very long-lasting, and it tends to accumulate over time. A plastic litterbox absorbs the odor, and even if you clean it regularly, it doesn’t disappear completely. Even a scented litter won’t help to eliminate it. The simplest way out is just to change the litterbox every few months.

Frequently Asked Questions

Q: Can I Flush Cat Litter?

A: Not all types of cat litter can be flushed. Thus, traditional clumping clay litter must never be flushed – its hard abrasive particles can damage both a toilet bowl and waterways. Almost all plant-based options and some kinds of mineral litter can be flushed – they have a softer texture and their clumps dissolve in the water without damaging anything. Before buying litter, check whether it is flushable or not.

Q: Is Scoop Away Cat Litter Flushable?

A: No, it is not. Scoop Away focuses on conventional clumping clay litter manufacturing; they don’t produce flushable, biodegradable, or other alternative options.

Q: Can you Flush Cat Poop from the Litterbox down the Toilet?

A: You are not recommended to do so if you live near the sea or a river, especially if your sewer system is connected to it. You are also not recommended to flush cat poop in a septic system. Cat poop can be a source of numerous infections and bacteria.

Q: How to Dispose Used Cat Litter?

A: It depends on its type. Flushable litter can be flushed in the toilet. Non-flushable litter must be disposed of according to the manufacturer’s instructions. Commonly, it is placed in plastic bags and thrown away with household waste.

Q: Is Naturally Fresh Cat Litter Flushable?

A: Yes, Naturally Fresh litter from Blue Buffalo is flushable. It is made of walnut shell, which is sewer-safe but is not septic-safe.

Q: Is Naturally Fresh cat litter flushable?

A:Yes, it is. Naturally Fresh is a series of all-natural biodegradable products that can be flushed, as it doesn’t contain abrasive particles, such as clumping clay. This litter is made of natural walnut shell, which is soft and well-clumping; at the same time, it easily dissolves in the water. It is safe for sewer systems; however, it is not recommended for septic systems. If you have a septic system, consider buying another type of flushable cat litter.

Q: How Deep Should Your Cat Litter Be?

A: Several factors affect the most expedient depth of cat litter including the type of litter, the number of cats, how often you are ready to clean it, etc. Consider these points: Cat litter is composed of different ingredients such as silica, clay, biodegradable materials, etc. If you've opted for a non-clumping variant such as crystal litter, the recommended depth will be from 2 to 3 inches for every cat. If you are ready to clean the litter frequently, the level of litter can be a bit lower. Fill up the box to the higher edge if you plan to clean it every other week. For older cats, don't make the litter too deep since they may experience some difficulties in their joints. Long-haired cats prefer shallow levels of litter, while short-haired cats love digging into the litter box deep. For kittens, maintain a maximum 2 inches depth of cat litter since they have short legs and are relatively weak. Additionally, if you notice any of these signs, it means you've used too much litter: the cat flings the litter out of the box; the cat goes halfway in only; the cat slides and slips in the box.

Is flushable cat litter really flushable?

Cindy Vargas

Most cat litters are clay-based. Some clump, some don’t. Clumping litters in particular are popular for their ease of removing urine as the litter absorbs and creates scoopable clumps. The litter doesn’t need to be replaced as often as non-clumping litters do. However, these clay-based litters end up in the trash, often in plastic bags, where they contribute to landfill sizes and other environmental woes. Clay-based litter doesn’t break down in compost heaps, and the clay itself itself is often derived from materials that are gathered through strip-mining processes.

Nicholas Lambert

Any biodegradable litter can burden delicate plumbing or a septic system, causing undue wear and potentially damaging your system over time. Even the best flushable cat litter should go down gradually. Go slowly and let each clod dissolve before you flush it.

Crystal Meyer

Litter boxes and kitty litter may not be the most enjoyable part of cat ownership, but they are an unavoidable one. After all, kitty has to go potty somewhere. Litter box furniture can help hide your cat’s litter box so it’s not so obvious, but you’ve got to have one. And you’ve got to have the stuff to fill it with.

Roberto Kelley

What is the Best Type of Cat Litter?

Melvin Wade

The litter includes an innovative formula which means that liquids are absorbed and remain trapped in a thin clump on the surface of the litter. The clumps are then easy to remove leaving the rest of the litter clean and ready to use. This is an excellent option for flushable cat litter, as it is completely environmentally friendly and it is also non tracking and neutralises odours.

Annette Hicks

How many litter boxes should I have, and what are the best kind?

Nicholas Franklin

Let’s be honest—no one likes cleaning the cat litter. Inhaling the pungent odor, sweeping up small granules of litter that skitter across the floor, and hauling a heavy plastic bag filled with waste out to the bin might be one of the least appealing parts of cat parenthood. Flushable cat litter is touted as a more convenient and sustainable option than conventional clumping litters that must be bagged and tossed in the trash
