    Okocat Wood Clumping Cat Litter

    If you’re looking for the best flushable cat litter for the money, then we recommend the Okocat Wood Clumping Cat Litter. This litter is made from natural wood fibers from pine, fir, and spruce. All of these have been sustainably sourced, making this litter environmentally friendly. The wood fibers immediately absorb liquid and odors on contact, meaning this litter doesn’t need to use artificial fragrances to cover up unpleasant odors. This litter forms easy-to-scoop clumps, and the manufacturers recommend flushing these separately when disposing of the litter.

    Most cats approve of the soft texture of this cat litter, and the fragrance-free formula appeals as well. This lightweight litter is easy to carry and pour and is 99% dust free. One 19.8-ounce box will last a two-cat household around 3 months, making this excellent value for money. Plenty of reviewers are happy with this litter, but it’s worth nothing that it can track on certain floor surfaces.

    3. Next Gen Pet Unscented Green Tea Clumping Wood Cat Litter — Premium Choice

    Next Gen Pet Unscented Green Tea Clumping Wood Cat Litter

    As our premium choice, we selected the Next Gen Pet Unscented Green Tea Clumping Wood Cat Litter. This all-natural cat litter is made from wood fibers and green tea leaves. Green tea contains catechin, which has antioxidant and antibacterial properties that prevent the growth of the bacteria responsible for those unpleasant litter box odors. While this litter doesn’t have any artificial fragrance added and it’s advertised as an unscented product, the addition of green tea gives off a fresh and pleasant natural scent.

    A 5-pound bag of Next Gen Pet should last one cat between 4 to 6 weeks. This lightweight litter is easy to use and forms easy-to-scoop clumps. It’s easy to flush too, and when you need to switch out your cat’s litter box contents, the remaining litter can be composted. Plenty of reviewers love this cat litter for its low dust, effective odor control, and eco-credentials.

    Pros
    • Choose from two bag sizes
    • Controls odors effectively
    • Low dust
    • Lightweight
    • Fresh natural scent
    Cons

    4. sWheat Scoop Unscented Clumping Wheat Cat Litter

    sWheat Scoop Unscented Clumping Wheat Cat Litter

    sWheat Scoop Unscented Clumping Wheat Cat Litter is designed for multi-cat households. This all-natural litter is made from biodegradable wheat granules. The starch within these granules immediately contains moisture, while the added natural enzymes get to work neutralizing the odor. This multi-cat formula has two-times stronger clumping and odor control compared to sWheat’s fast-scoop formulation.

    The gentle ingredients of this litter mean it’s vet-recommended for all cats, even kittens. This litter comes in three bag sizes, with the largest bag of 36 pounds being perfect for houses with multiple cats. Reviewers do note that this litter can track a little more than some other brands, and clumps of litter may fall apart if they’re left for a while before being cleaned out.

    Pros
    • Eco-friendly
    • Lightweight
    • Excellent odor control
    • No artificial fragrances
    • Low dust

    5. Cat’s Pride Premium Lightweight Cat Litter

    Cat's Pride Premium Lightweight Cat Litter

    Cat’s Pride Premium Lightweight Cat Litter stands apart due to the fact that it’s a clay litter, but it’s also flushable. Most clay litters use sodium bentonite, but Cat’s Pride is made using a different type of natural clay, although the brand doesn’t specify exactly what kind. This lightweight litter is easy to pour and store and comes in a plastic tub to keep it dry and fresh. The scented formula effectively traps odors to keep your house smelling clean and fresh.

    The highly absorbent clay forms hard clumps that are easy to scoop and completely flushable. Each 17.5-pound pail of litter should last a one-cat household up to 60 days. This flushable cat litter is great value for money, but some users do note that it can create quite a bit of dust. It’s also not recommended to flush this litter if you use a septic tank sewerage system.

    Pros
    • Good value for money
    • Lightweight
    • Fresh scent
    Cons
    • Only one size pail available
    • Not recommended for septic tank systems
    • Can be dusty

    6. Almo Nature Unscented Clumping Grass Cat Litter

    Almo Nature Unscented Clumping Grass Cat Litter

    Almo Nature Unscented Clumping Grass Cat Litter is made from 100% vegetable fiber, which is flushable, biodegradable, and compostable! The starches within the cassava root, which provides the vegetable fiber, help clump moisture together, while the natural plant enzymes help neutralize odors. The soft texture of this litter is great for sensitive cats that don’t like the feel of harder litters under their delicate paws.

    A 10-pound bag of this cat litter should last just under 10 weeks for one cat. While this cat litter is easy to flush and effective at clumping, the soft texture can create quite a bit of dust, as well as stick to your cat’s paws and track through the house.

    Pros
    • Choose from two bag sizes
    • Made from natural materials
    • Effective clumping
    Cons
    • Quite dusty
    • Not made in the U.S.A.

    7. Cat’s Pride Scoopable Scented Clumping Litter

    Cat's Pride Scoopable Scented Clumping Litter

    Cat’s Pride Scoopable Scented Clumping Litter is a lightweight litter, with 12 pounds providing the same number of uses as 20 pounds of a similar brand. One 12-pound jug of this litter should last two cats 15 days or one cat roughly 35 days. This scented litter helps reduce odors, but some cats may find the smell too strong, especially if they have allergies or breathing problems.

    This clay-based litter doesn’t use sodium bentonite, so it’s safe to flush down residential sewage systems, although Cat’s Pride doesn’t recommend that you flush this down septic systems. This Cat’s Pride litter forms good clumps initially, but they can start to fall apart if you don’t clean them out right away.

    Pros
    • Lightweight
    • Effective odor control
    • Good value for money
    Cons
    • Scent may irritate some cats
    • Not dust free
    • Fine consistency can track

    8. Rufus & Coco Wee Kitty Corn Cat Litter

    Rufus & Coco Wee Kitty Corn Cat Litter

    The Rufus & Coco Wee Kitty Corn Cat Litter is a natural, unscented cat litter made from corn. It absorbs four times its own weight and forms easy-to-scoop clumps. The clumps break down once immersed in water, so Rufus & Kitty recommends leaving the clumps in your toilet bowl for a minute or so before flushing. The formula is low tracking, so you won’t have to clean up litter spread around your house. It’s available in two bag sizes: 8.8 pounds and 20 pounds.

    An 8.8-pound bag should last one cat up to 8 weeks. This litter can be quite dusty, especially as you get toward the bottom of the bag. It’s also not the best at controlling odors if left to sit without being cleaned, but many cats prefer this unscented litter to those with a strong scent. It can also stick to the base of your cat’s litter box, which can make complete litter changes take longer.

    Pros
    • Biodegradable
    • Clumping
    • Absorbent
    Cons
    • Dusty
    • Not good at controlling odors
    • Can stick to the base of the litter box

    9. Bolux Flushable Cat Litter

    Bolux Flushable Cat Litter

    Bolux Flushable Cat Litter uses clump-lock technology to absorb your cat’s pee and has carbon-activated odor-absorption technology to effectively neutralize any smells. This litter is made from natural plant ingredients, but it’s not clearly listed on the box exactly what these ingredients are, although it seems to include soya bean tofu.

    This best flushable litter only comes in one size box of 5.5 pounds, which doesn’t last long, especially if you have multiple cats. This litter has a soft texture, but the pellets can easily disintegrate under your cat’s paws when they tread in the box. This means it’s going to end up sticking to their paws and tracking through your house. This litter can be flushed — as long as you leave it to dissolve for 30 seconds first!

    Pros
    • Soft texture
    • Carbon odor control
    • Low dust
    Cons
    • Box doesn’t last long
    • Can track through the house
    • Pellets dissolve too easily

    10. Weruva 0850 Green Tea Natural Cat Litter

    Weruva 0850

    Weruva 0850 Green Tea Natural Cat Litter is an all-natural cat litter made from Hinoki wood and green tea. This hypoallergenic formula is completely grain-free, making it a good choice for kitties with allergies. It can even be used by kittens. An 11.7-pound bag should last one cat up to 50 days. Hinoki wood naturally stops the growth of bacteria and mold, while green tea has antioxidant properties that help reduce odors and stop bacteria from multiplying.

    This litter is low dust, and although it’s not artificially fragranced, the green tea and Hinoki wood both have a pleasant natural scent. You may need to find a different litter scoop for this litter, as the pellets are quite large and won’t always fall through some litter scoops. Potato starch is added to this litter as a clumping agent, and it’s quite effective as long as you scoop out the clumps relatively quickly.

    Pros
    • Choose from two bag sizes
    • Hypoallergenic
    • Grain-free
    Cons
    • Tracks through the house
    • Some people don’t like the smell
    • Can stick to longhaired cats

    Buyer’s Guide: Choose the Best Flushable Cat Litter

    You might be wondering exactly what to look for when you’re on the hunt for a flushable cat litter, and we’ve put together this guide to answer all your questions.

    What are the best flushable cat litters made from?

    Flushable cat litters are made from a wide range of materials, including wheat, corn, wood pellets, some types of clay (not sodium bentonite), and even soya beans!

    You can choose the material that your cat prefers, whether you want a scented or unscented litter, clumping or non-clumping — there are so many choices!

    Why should I use flushable cat litter?

    It might not seem so at first glance, but traditional clay cat litters create a great deal of environmental impact. They’re usually made from sodium bentonite clay, and the mining method to obtain this is incredibly wasteful and damages the area surrounding a mine. You can’t flush sodium bentonite clay litters, as they can form hard lumps that block your sewage system. Instead, you’ll need to dispose of clay cat litter in a landfill, creating more waste. If you’re looking for easy ways to lower your impact on the environment, then switching to a flushable litter is an excellent decision.

    You can also wave goodbye to heavy trash bags full of litter, which is an advantage if you live in an apartment. You’ll also reduce your usage of plastic bags.

    Are all-natural cat litters flushable?

    Not necessarily. Just because a cat litter is labeled as natural, that doesn’t mean it’s necessarily flushable. After all, bentonite clay is a natural product, but it’s definitely not advised to flush this type of litter down your toilet!

    Always check the label if you’re specifically looking for a flushable litter, and of course, any of our 10 recommended litters are safe!

    Can I use flushable cat litters with a septic tank?

    Yes and no. Some flushable litters are deemed safe for use with a septic tank system, and others aren’t. Always check the label if you want to use flushable litter with your septic tank.

    Problems with flushable litter

    Flushable litter sounds perfect, but there are a few issues to be aware of. Cats can carry a parasite known as toxoplasma gondii, and this gets passed through their poop. Humans can become infected through touching cat poop, and although most people won’t show any symptoms, this can cause a problem for immunosuppressed people and pregnant women.

    Flushing cat litter down your toilet can lead to this parasite becoming present in rivers and ultimately, the sea. There, it can affect wildlife.

    If you live in California, you should not flush your cat’s litter down the drain, as the state advises against it.

    Flushable cat litter can sometimes cause clogs, especially if you try to flush too much of it at once. Each manufacturer will recommend how many clumps it’s safe to flush at once (assume one at a time if it’s not stated), and it’s usually best to leave the clumps to dissolve a little before you flush.
