Emptying the kitty litter box is a chore that no pet owner looks forward to. It can be messy, smelly, and results in a bag of waste that is best carried right to the garbage can. Switching to flushable cat litter can take at least one of those steps out of the equation.

Opting for flushable litter is also more environmentally friendly. Instead of contributing to a landfill with a waste bag full of litter, your cat’s business is disposed of in a way that is more sustainable. Many flushable cat litters are made with eco-friendly materials that are safe for your plumbing and your pet. Consider what texture your cat prefers, since some can require an adjustment from traditional clay litter.

Our list includes options for clumping litter, multiple cats, tackling odors, and training kittens. All of them are able to be flushed down the toilet after your cat is done with their business. No more smelly trips to the garbage can with a waste bag in hand!

1. Overall Best Flushable Cat Litter: sWheat Scoop Wheat-Based Natural Cat Litter

In our review, the best flushable cat litter is the sWheat Scoop Wheat-Based Natural Cat Litter. This litter is made of wheat with natural enzymes that trap odors. The most popular option from sWheat Scoop is the unscented clumping option, which performs very similarly to traditional clay litter without dust. It does come in a multi-cat option as well with superior odor trapping. This litter clumps, making it easy to scoop out waste and put it into the toilet bowl. It does have some dust and tracks through the house, especially when the pieces get caught in your cat’s paws. Vacuuming periodically will likely take care of any issues.

This litter can be flushed down just about any toilet. It clumps quickly, which also helps trap odors before they can stink up your room or house. It is also available in 12-pound, 25-pound, and 36-pound bags. We recommend starting with a smaller bag to get your cat used to the new texture first. It performs like clay litter but does have a slightly different texture for your kitty. Once they transition to the new litter, buying in bulk can save money.

This litter is more expensive than clumping clay litter but is made with fewer chemicals. This health benefit was important to many reviewers. “Yes, it is expensive, but I don’t want to compromise on our health,” said one reviewer. All litters create some dust, even if it is not enough to bother you. Using all-natural ingredients like wheat and forgoing chemical perfumes can reduce the exposure for you and your pet to potentially harmful ingredients.

2. Best Pellet Litter: K Kamy’s Zoo I Am Tofu Clumping Pellet Cat Litter

That’s right–this clumping pellet-style flushable cat litter from K Kamy’s Zoo is made of tofu! When your cat uses it, the pellets expand to trap the liquid or waste as well as the odors. Simply scoop and flush. The pellets are made with corn starch and soy and can absorb 4 times their weight. It also has a light scent, which can be a pro or con depending on your preferences.

Even large amounts of this litter work well in the toilet. One reviewer was worried when her daughter dumped the entire box into the toilet and flushed it. But this flushable litter was truly flushable, even in large quantities. “The litter melts like toilet paper,” she said. “Totally satisfied and the litter scent (peach) is very pleasant not overwhelming.”

It is important not to use this litter with a self-emptying litter box. You will need to manually scoop and flush instead. Reviewers who tried it with a self-emptying litter box found that it stuck to the scoop arm. You will need to scoop yourself and put the waste and soiled pellets into the toilet.

One added benefit of using an all-natural litter like this one is that it is not harmful to other pets. If you have a curious dog who likes to explore, you don’t need to worry about them ingesting this litter and getting sick. If they eat clay litter, it can cause stomach upset or make them seriously ill. “We also have a puppy, who occasionally will get into the litterbox,” said one reviewer. “The tofu litter won’t cause her harm, whereas the clay litter made her sick.

3. Best for Odors: PETKIT 5 in 1 Mixed Cat Litter

There’s no denying that this is an expensive cat litter. At over $50 for 32 pounds in four bags, this is one of the pricier flushable litters on the market. But many pet owners are willing to pay the premium price because of how well it traps odors. The pellet-style litter is made of plant and corn starch, which dissolve when they go into the toilet. The litter won’t clog your plumbing and flushes easily.

The odor-absorbing comes from activated carbon and deodorant particles in the litter itself. You can see them as the blue and purple pieces sprinkled throughout the pellets. Because the litter is solid, it is also virtually dust-free. This helps keep litter where it needs to be and reduces the tracking around your house. One reviewer switched to PETKIT pellet litter to reduce the dust and tracking. “So far in the first week, I haven’t found any of these around the house or in the cats’ favorite spots like I always did with the little clay pebbles,” the reviewer wrote.

This unscented corn-based clumping option from World’s Best is perfect for your kitten’s nose and developing body. Without the addition of chemical perfumes, you can be sure that you are providing your kitten with a safe place to learn to go.

The texture of this litter is similar to clay litter, with small particles that clump easily. Some reviewers noted that it breaks down over time. The company recommends emptying the box and replacing with fresh litter. “This stuff is FANTASTIC! It clumps beautifully, and ensures no litter box smells extremely well,” said one reviewer. “I followed the directions and do a total change out once a month.” Working this change out into a litter cleaning routine seemed to be the best way to ensure that the litter performed well over time.

Choosing the Best: What to Look for

When deciding which flushable litter is best for your cat and your home, there are options made of different materials, with various odor-absorbing qualities, and in a variety of textures. Here we look at these factors.

Material

Flushable cat litter can come in a variety of all-natural materials, including wheat, corn, wood, and even tofu. There are a lot more options that are environmentally friendly and safe for your pets in the flushable litter market than in traditional clay-based litters. Some clump while others absorb liquid waste to keep it trapped. You can also choose a flushable litter that has a combination of materials, such as corn and wheat.

Smell

Many people who want an eco-friendly option prefer unscented litter that does not have any potentially harmful chemicals or perfumes. These can be a bit smellier overall. If you don’t mind perfume smells, you can choose a scented litter that absorbs the smells of cat waste while also replacing it with an added smell that is more enjoyable. You can also look for an odor-absorbing litter that has materials like activated carbon that trap odors.

Texture

The biggest difference between flushable cat litter and traditional clay cat litter is the texture. Litter made of materials that can be flushed, such as wood, wheat, or corn, has bigger particles or even pellets. These create a different surface for your cat to stand on as they go to the bathroom. Some cats make this transition quickly while others need more time to get used to their new setup. Consider having multiple litter boxes available as they switch to a new litter.

Verified Review: User Experience

Reviewers raved about our top pick, the sWheat Scoop Wheat-Based Cat Litter. Many called out its odor-controlling abilities as being some of the best among flushable litters that they tried. “This does a really good job of clumping and more importantly, it is awesome at keeping the odor down,” said one reviewer. “We have four cats and people have remarked that they never would have guessed, since there is no litter box smell in the house.” Any litter that can contain the odors of litter boxes with four cats in the house has got to be doing something right!

It is expensive but many reviewers said that flushable litters were worth the money. They tended to prioritize all-natural products that were safe for their cats and other pets and were willing to spend more for these products, as long as they performed well. One reviewer switched to World’s Best Unscented Clumping Corn Cat Litter and liked the performance. “World’s Best unscented Clumping Corn Cat Litter IS the BEST. We wouldn’t use anything else,” they wrote. “We feel it’s safe for our cat and so easy to scoop and discard.”
