Best Clumping Cat Litters for 2020

Cat litter is an essential piece of equipment for pretty much any cat, even if they spend a lot of time outdoors. You never know when they may not be able to go outside, such as in bad weather or if they need to be kept indoors for health reasons.

So ensuring your cat is comfortable with using a litter tray is really important. Clumping litter is often easier for owners to deal with and can often be preferred by cats, too.

We’ve given clumping cat litter a dedicated review because it is so popular, and there are dozens of varieties out there. Check out our top picks below to find the best one for your kitty.

We’ve also reviewed non-clumping cat litters in case you need to try both kinds.

    Top 10 Best Clumping Cat Litters Reviewed

    1.
    Worlds Best Cat Litter

    A negative of having a cat litter tray indoors is the inevitable smell after it has been used, but thankfully there is an awful lot of litter out there now which can keep the whiffs at bay.

    The odour control is present thanks to the addition of all-natural plants, so there are no nasty chemicals. Two varieties are available, Original and Multiple Cat, so you can pick the option which is best for your lifestyle as both work equally well.

    It describes itself as one of the strongest odour prevention litters on the market, and smells stay trapped well inside the litter so can’t reemerge. Flushable, it has been tested for safety with septic and sewer systems so should cut down on the trips to the bin and inevitable landfill situation in small doses.

    As it is made from corn, you get the volume and efficiency there without the weight so it is easy to manage. It also makes it naturally free of dust and is a sustainable material. You can pick from a larger bag too if you like.

    Features

    • Made from sustainable corn
    • Flushable

    Specifications

    • Size: 6.35kg
    • Type: Granules
    • Dimensions: 11.1 x 26.7 x 54.6 cm

    2.
    Ever Clean Multi-Crystals Clumping Cat Litter

    Crystal clumping litter can be hard to come by but is ideal for those cats who seem to have an aversion to clay materials.

    Mixed into their ordinary clumping litter are small silica crystals, which further increase the absorption rate. There is no smell of urine, faeces or ammonia from cats with urine issues, and the fragrance-free property will be perfect for humans and cats with an aversion to scents.

    The activated carbon technology traps the odours as opposed to just masking them, and the 10-litre sized packet can last for up to two months based on average usage and emptying.

    The waste will need disposing of in the household refuse and can’t be flushed.

    Features

    • Non-clay
    • Highly absorbent

    Specifications

    • Size: 10L
    • Type: Silica Crystals
    • Dimensions: 11.7 x 28.8 x 33.8 cm

    3.
    Catsan Cat Litter

    Also one of the best for low dust properties, this 100% biodegradable, 100% made from plants litter is great for the planet, your kitty, and yourself.

    It automatically forms small clumps when it comes into contact with liquid, so you can clean up straight away. This also means that you can minimise your wasted litter as it will affect as little of the litter as possible.

    There is a natural scent given off so it won’t be unpleasant or offputting to your kitty’s nose, and the texture is soft to paws. Catsan is one of the best-known brands when it comes to litter, so you can trust the efficiency and reliability of this variation.

    Features

    • Biodegradable
    • Natural scent

    Specifications

    • Size: 20L
    • Type: Granules
    • Dimensions: 33 x 20 x 47.5 cm

    4.
    Pets at Home Ultra Freshness Premium Clumping Cat Litter

    A litter described by many users as one of the best in the Pets At Home range, this is an ultra-high performance blend which clumps fast and makes it easier for you to manage.

    The clumps formed are firm, almost concrete-like, for easier removal with a scoop, and it makes a very good option for homes with multiple cats. The clumps don’t fall apart on the scoop or make a mess in the waste disposal. 

    The size of the granules is a nice balance between being fine enough to be comfortable underfoot and large enough to not stick to paws to track. As a bonus, it is low dust. The lavender scent is weak enough to not put the cat off using the tray but is strong enough for human noses to smell the benefit and mask the unpleasantness.

    Features

    • Great size granules
    • Comes in a box for safe storage

    Specifications

    • Size: 10L
    • Type: Granules
    • Dimensions: 33.8 x 28.8 x 11.7cm

    5.
    Okoplus Cats Best Original Clumping Cat Litter

    Able to absorb up to three times more liquid than their closest rivals, this Cat’s Best litter would be just as perfect for multiple cats than a single feline.

    This makes it highly economical both in terms of cost and waste, and there is no bad smell released, even after a long time. Only the soiled area will need to be removed from the tray, cutting down on the frequency in which it needs to be emptied. Okoplus say you could go as long as 4-6 weeks with the same base content in the tray.

    Compostable and 100% biodegradable, it won’t still be around in years to come. You can even dispose of clumps in the toilet and wait for them to dissolve before flushing. It isn’t dusty, and the tracking is kept to a minimum and not enough to really bother anyone.

    Features

    • Top for absorption
    • Compostable and flushable

    Specifications

    • Size: 30L/13kg
    • Type: Granules
    • Dimensions: 14 x 36 x 90 cm

    6.
    Tailmate Super Clumping Cat Litter

    In the USA, house cats are the norm, so when we are talking about litter, you will know that something from America is going to be good reliable stuff.

    It is really quick at clumping, as trapping the liquid limits the wetness from seeping, sinking to the bottom or sticking to the sides of the tray. This makes it easy to scoop up ASAP, reducing the likelihood of smells.

    Even if you can’t get to it straight away, special odour-reducing properties will ensure the smell is kept to a minimum. This reduces the need to change the litter frequently, and it is 99% dust-free so won’t make much mess from scooting either.

    It gives off a faint talcum baby powder scent, and it comes in a sturdy bag so you can ensure it won’t rip and tear when being stored.

    Features

    • Clumps super-quickly
    • Great at keeping smells at bay

    Specifications

    • Size: 15L
    • Type: Granules
    • Dimensions: 8 x 54 x 36cm

    7.
    Sanicat Gold Talcum Powder Scent Clay Fine Granule Ultra Clumping Cat Litter

    When buying a scented cat litter, you need it to not be too overpowering but still ensure the odour is not just trapped but the area smells nice in response.

    This particular grain is talcum powder scented, so is fresh, hygienic and pleasant. It’s still gentle though, so won’t put off cats who aren’t keen on fragrant smells. Able to absorb up to 250% of its weight in liquid, the frequency in which it needs changing and cleaning out will be reduced which makes for an easier life for owners.

    Its dust-free and the granules are quite fine, so it will feel good under paws. Although this does mean it is not suitable for kittens or cats who are just getting used to their tray. The price is on the higher side for the size of the bag you get, but the fine grains and scent will make it a price worth paying for some.

    Features

    • Pleasant subtle scent
    • Dust-free

    Specifications

    • Size: 5L
    • Type: Granules
    • Dimensions: 28 x 18 x 10.5cm

    8.
    Sanicat Oxygen Power Soap Scent Clay Granule Ultra Clumping Cat Litter

    This is one of the cleanest and most hygienic litters on the market, and while the soapy smell may not appeal to some little noses, it’ll work well for any cats who need everything as clean as can be.

    The active oxygen keeps everything smelling nice and fresh by eliminating odour, and there is also disinfectant in there so when the business has been done and the mess dealt with, the litter leftover will still be perfectly hygienic.

    We will admit that a few reviews have said that the ‘soap’ smell is more akin to the cleaners used in a public loo as opposed to your bar at home, but it is still better than the alternative smell.

    Features

    • Noticeable soapy smell
    • Good value for money

    Specifications

    • Size: 10L
    • Type: Granules
    • Dimensions: 40 x 26 x 10cm

    9.
    Pettex Premium Dust Extracted Clay Granule Clumping Cat Litter

    With a dust-free specification which has a high level of odour control to clamp down on unpleasant smells, this litter will be great for anyone who is looking for something biodegradable and easy to manage.

    As it clumps, you can remove offending patches of litter to keep everything clean and topped up. There are no additives, just natural clay, and it also reduces the likelihood of bacterial activity.

    Clumps form after around 10 minutes so it isn’t the most immediate but still not an issue. It will be good for anyone with asthma or respiratory issues, and there is little tracking too.

    Features

    • Hygienic
    • Low tracking

    Specifications

    • Size: 20kg
    • Type: Granules
    • Dimensions: 50 x 36 x 10cm

    10.
    Clean 'n' Tidy Clay Fine Granule Ultra Clumping Multi Cat Litter

    A bit of a smaller bag for anyone who can’t keep a huge one in storage.

    It describes itself as maximum clumping, eco-friendly and with a triple layer of freshness. Perfect for high usage trays and homes with more than one cat.

    Moisture activated botanical scents mean it won’t give off any smell all of the time but will be there when it is needed the most. The addition of baking soda helps with the moisture control and will keep the whole tray fresher for longer, and it’s 99% dust-free so there will be no irritated eyes and noses, or tracking footpads.

    It should last up to four times as long as ordinary non-clumping litters when you follow the instructions, which is good for those who hate waste.

    Features

    • Low tracking and dust
    • Long lasting

    Specifications

    • Size: 7kg
    • Type: Granule
    • Dimensions: 30.5 x 25.2 x 31.3cm

    Buying Guide

    Bag Sizes

    These are measured in both litres and kilograms which makes it slightly more confusing, depending on the material of the cat litter.

    Sizes will generally come in 4kg, 7kg, 10kg and 20kg. Think about storage, how large a bag you can lift at any one time and when you want to have to buy another bag.

    Clumping Cat Litter Varieties

    Clay

    By far the most popular and widely available. Clay naturally clumps when coming into contact with moisture, and it is often cheap to both manufacture and purchase. Unfortunately, though, it is not biodegradable and can cause a lot of dust which is bad for pets and owners with breathing difficulties

    Paper and Wood

    Clumping varieties of these materials are rare so can be pricey, but maybe worth it if you’re concerned about the environment

    Corn

    The most absorbent form of plant-based litter, which is why it is a good swap for the paper and wood pellets mentioned above. Because it is absorbent, it can naturally clump, but again it can be rarer to buy

    Price

    You will often pay more for the clumping litter versus the non-clumping, even if it is just basic clay options. It also applies to the own-brand varieties.

    This could be a deciding factor if you’re wondering whether to go for clumping or not, but basic clumping options will generally not be too extortionate.

    For a 10kg bag, you could pay anywhere between around £10 up towards £20. Bear in mind that those at the higher end of the price scale may have extra properties which mean they don’t need to be changed as often which could save you some money in the long term.

    Other Buyers Ask...

    What Is Clumping Cat Litter?

    Clumping litter reacts with urine to bond together when used, making it easier to remove any ‘used’ pieces.

    You can take these out after each use, and top the litter up if your cat likes their tray to be the most sanitary it can be. You should still completely empty and clean the tray every week or so, but overall it should reduce waste as you’re not getting rid of unused litter.

    Why Should I Choose Clumping Over Non-Clumping?

    It is thought that clumping litter is preferred by many cats, and this is before even mentioning that it is a lot easier for you to manage too.

    Cats seem to like the feel of clumping litter under their paws as it is often made from materials such as clay. And as mentioned above, you can ensure that the litter stays as clean as possible which helps the fussiest of kitties. It makes your job of scooping up any used parts a lot easier, too.

    How Often Should I Replace Clumping Cat Litter?

    Clumps should ideally be removed after each use, which is twice daily. Some litters will say how long they can go before needing to be replaced fully, but the general rule is that all litter should be dumped after a week, and the litter tray washed, dried and ready to go again.

    Should I Pick A Flushable Litter?

    People may believe that flushable litter can cause issues in the long term, just like with flushable wipes for humans which actually gather up en masse and can cause blockages.

    But if used correctly, flushable litter can actually be really great for cutting down on waste. Just place the clump in the toilet and wait for the litter to dissolve before flushing, so there’s nothing solid which can cause issues. You should only get rid of one clump at a time.

    If your cat is on treatment which makes them slightly radioactive (such as for hypothyroidism), then the flushable litter will be necessary.
