Best Non-Clumping Cat Litters for 2021

Indoor cats and those who won’t entertain going outside when the weather is even slightly inclement will need a suitable cat litter tray somewhere accessible.

Their tray needs to provide a stress-free environment for them to go to the toilet, and as all cats are fussy creatures, everything from the size of the litter pellets to how much is in the tray and whether it gives off any scent will be important.

You may need a case of trial and error to find the best for you and your cat but to give you some guidance, these are our reviews of the best varieties of non-clumping cat litter around.

In case you don’t know which is best, we have also tested clumping cat litters.

    Top 10 Best Non-Clumping Cat Litters Reviewed

    Catsan Hygiene Non-Clumping Cat Litter

    This non-clumping granule litter soaks up liquid so quickly that there is no chance smells can even develop, which is good news for your nose.

    The material is naturally absorbent, so there’s no additional additives or perfumes, meaning your cat’s toilet can be kept as natural and harm-free as possible. They also don’t give off any dust, so lungs and surrounding surfaces are kept clean.

    The only additions are active ingredients to stop the production of bacteria and growth which provides long-lasting odour protection, so you can leave it in there for a little bit longer than usual which should reduce waste (and the money you spend on litter).


    • Great odour control
    • Natural and ‘litter-like’


    • Size: 20L
    • Type: Granules
    • Dimensions: 64.3 x 51.8 x 29.2 cm

    Pettex Silica Cat Litter Granules

    Able to absorb urine really well and quickly, causing little odour and mess, silica gel crystal litter is a favourite among owners who have a litter tray in the house and would rather not have to smell the results.

    It remains dry to touch when it has absorbed the liquid, so should be a bit more pleasant for you to change and also for your cat to use. This is why silica pouches are often used in packaging to prevent moisture and mould forming.

    Because it absorbs the liquid and allows it to evaporate naturally, no smell is given off, and there is no ammonia scent either. The chunky size of each granule means there is very little tracking, so should reduce the mess of the litter tray area and the risk that it will stick to their paws.

    It will stick to cat poo as well, slightly lowering odour from that as well as making it easier for the owner to remove. As a bonus, even a trayful of the litter is lightweight, making it easier for people who can’t lift heavy items.


    • No odours or smell
    • No need for it to clump


    • Size: 7.6L
    • Type: Crystals
    • Dimensions: 40.5 x 29 x 11.5 cm

    Fresh Paws Premium Wood Pellet Cat Litter

    Great if you want a larger bag which should last you longer for a good price, wood pellets are both environmentally friendly and highly absorbent.

    Wood also happens to be gentle on paws so most cats will feel comfortable using it. It also gives off a natural wood smell, not dissimilar to the scent they would ordinarily come into contact with outdoors so should not be too offputting.

    Talking of smells, it will largely trap the odour given off by toilet waste and reduce the likelihood of the ammonia smell. Lightweight, it is easy to both empty the tray and lift the bag to replace it or top it up.

    We will say that because it breaks down into sawdust when wet in order to be biodegradable, it will need replacing more often than other forms such as silica if you want to cut down on the dust effect.


    • Breaks down when wet
    • Good price


    • Size: 30L
    • Type: Pellets
    • Dimensions: 70.3 x 35.2 x 12.9 cm

    Pets At Home Non-Clumping Clay Cat Litter

    Do you go through cat litter at the speed of light and frequently find yourself trailing to the shops before they shut because Milo won’t dare go anywhere near an unclean litter tray? Are you fed up of carrying huge 20L bags of the stuff home on the bus after work?

    Cat litter can be hard to remember to buy, so having it delivered to the door frequently is a great idea for busy cat owners. Choose from 2, 4, 6, 8, 10 or 12-week frequencies so you never run out.

    Now for the performance of the actual litter – non-clumping clay can be hard to come by, but this one has been designed with water absorption properties without forming clumps. Because it absorbs the water, there is less mess created when you come to clean it out and less chance of smells.

    It is a little bit dusty like other forms of clay litter, and while it isn’t completely clump-free, you can certainly tell the difference.


    • Highly absorbent
    • Keeps smells to a minimum


    • Size: 20L
    • Type: Granules
    • Dimensions: 60 x 32 x 9cm

    Platinum Plus Wood Pellet Cat Litter

    To get a huge 30-litre bag of cat litter which should last for a good few weeks is pretty good going.

    Wood pellets make for cheap litter in general, but there is a risk that the wood is quite dusty and not the greatest quality. However, this blend is made from a particularly high grade of 100% virgin softwood, so not only does it feel okay under your cat’s paw pads but they’re light in colour too for easier management.

    The dust is extracted from them during the manufacturing process to ensure minimum mess, and the wood is highly absorbent. While not all dust is gone, and it will get sawdusty when used and wet, it is a lot less messy than you’d expect for the price.


    • Suitable for cats of all ages
    • Softwood


    • Size: 30L
    • Type: Pellets
    • Dimensions: 3 x 59 x 89cm

    Pettex Pampuss Woodbase Cat Litter

    While no litter can be 100% dust-free, especially if it has recently been used by your cat, Pettex go to great lengths to ensure superior dust extraction so you won’t be enveloped in a cloud when filling the tray up.

    Paws will also stay clean after it is used, to avoid that trail of pawprints going through the house. And, you have the added bonus of a slight pine fresh aroma coming from the pellets, which is natural so there are no added perfumes which could irritate your cat.

    Able to retain up to 2x their weight in liquid, they should last a little longer than some litter types which need changing daily which also boosts their eco-friendly properties. No trees are felled in the making of it either as it is 100% reclaimed timber.


    • Not powdery
    • Pine scent


    • Size: 30L
    • Type: Pellets
    • Dimensions: 37.6 x 57.4 x 8.4 cm

    Sanicat Aloe Vera 7 Days Non Clumping Cat Litter

    A fine texture and subtly perfumed, this is a clay cat litter which can absorb all of those nasty smells and stains which are all too common for cat owners.

    While its claim to last seven days will vary between situations, a lot of users say it is one of the best they have tried for long-lasting results. The fine texture is good for any cats who don’t seem to like larger granules or pellets under their paws and need something more gentle.

    It doesn’t give off much of an odour, just enough to please your nose but keep your cat happy too. Sanicat describes it as an ‘air freshener effect’, and the fact that it is aloe vera means it isn’t overwhelming or unnatural.

    We actually like that it comes in a small package of just four litres, as it will be ideal for anyone who perhaps doesn’t have the space to store a huge one or can’t lift large bags and would like to use the lot in one go. It thankfully doesn’t cost you a ridiculous amount for the privilege either.


    • Small bag
    • Pink colour for something different


    • Size: 4L
    • Type: Granules
    • Dimensions: 38 x 20 x 11cm

    Extra Select Premium Hygiene Cat Litter

    Low dust, non-clumping, and offering odour protection, this hygienic fine-porous litter is crafted from natural quartz sand and lime.

    Liquid is absorbed very quickly, and therefore odour doesn’t have a chance to develop. It comes in a huge 20L bag which should see you through a good few weeks, and you dispose of it in the household waste.


    • No odour
    • Soft granules


    • Size: 20L
    • Type: Small Granules
    • Dimensions: 16 x 30 x 42 cm

    Breeder Celect Recycled Paper Pellet Non-Clumping Cat Litter

    The planet is a big concern on everyone’s mind these days, and if you’re emptying your cat litter into a bin and it isn’t able to break down, that is a lot of contribution towards the landfill every year.

    This is a paper pellet litter, which is not only much more absorbent than a wood pellet, but natural cellulose fibres (such as newspapers) are recycled and repurposed. This gives the papers a second life, and it won’t sit around in the rubbish tip for years.

    It is a clinically clean super hygienic litter, so you don’t have to worry that the recycling process will leave behind any of the dirt and germs originally on the paper. There is no additional binders, additives or chemicals either, so it is safe for all ages from kitten to adult cat.

    We like that the paper covers odour too, without making a woody or chemical smell. Our only criticism is that it isn’t easy to separate the soiled litter from unsoiled, but this won’t be an issue if you’re one to clean up ASAP anyway.


    • Low impact
    • Kitten-safe


    • Size: 20L
    • Type: Pellet
    • Dimensions: 41 x 30 x 14cm

    Catsan Smart Pack Cat Litter 2 Inlays

    This is a bit of a twist on your traditional cat litter and tray setup. If you use liners to make the job of changing the litter a bit easier and prolong the duration in which the litter can stay in the tray without starting to smell or make a mess, then you will probably be drawn to these.

    An all-in-one litter solution, these inlays take the form of a plastic bag filled with cat litter which you can place inside the tray. The elasticated hem wraps around the side of the tray, and when the time comes to change it, just take out the bag, pull the hem tight, and place straight into your waste disposal.

    There’s no need for a scoop or any messy bagging, and you can just replace with a new bag for ease. The liner absorbs any liquid, so the litter stays drier for longer, and it is as efficient as 30 litres of the conventional non-clumping litter so there is enough in the pack for comfortable toilet time.


    • Easy-to-use option
    • No fuss or measuring out


    • Size: 2 x 4L
    • Type: Granules
    • Dimensions: 11.1 x 39.8 x 19.8cm

    Buying Guide

    Bag Sizes

    This is measured in either litre (the most common option) or gram/kilogram.

    The most popular bag sizes are usually 4L, 6L, 10L, 20L and 30L. It is the norm to use around 4 litres of litter in a tray at any one time, so think about how large a bag you can store, how large a bag you can lift and how long you want it to last before having to buy a new one.

    Prices are often pretty relative, so you shouldn’t really pay over the odds for a 4-litre bag compared to a 30 litre unless it is very special litter. We will say that ordinary plain litter tends to come in the larger bags, however, and that it is often great value so well worth giving a go if you know your cat likes that variety.

    Cat Litter Varieties


    Often come as gel crystals. The most absorbent type, hence their popularity. A natural material, they do this quickly so there’s less chance of smells or mess.


    Usually come as solid pellets. As they’re plant-based, they’re often dust-free, biodegradable and naturally deodorise


    The best option if you want something made from recycled material which is better for the planet. They cut down on the manufacturing of new materials while offering the same benefits as wood while being more absorbent


    Often seen more with clumping litters due to its reaction when wet, but if made from forms other than bentonite it is less likely to clump. It is relatively cheap but can cause a lot of dust and mess

    Litter Types


    Mostly found in the silica material. Almost round in shape, and usually the perfect size for cats


    Longer, thinner pellet-shaped grains. This increases their chance of absorption and also makes them better for cats who don’t seem to like finer materials under their feet


    Ordinary litter shapes, usually round-ish and can come in fine or larger varieties anywhere between the texture of sand and gravel. The larger varieties are often good for younger cats

    Scented Cat Litter

    Your nose may not agree, but past studies have actually shown that cats will generally pick a litter which has no strong scent and is pretty neutral in smell. If there is too much fragrance coming from the litter tray, it could even mean they avoid going in altogether.

    But if you feel that some sort of nice smell is a must then go for one which explicitly says the smell is only activated when the litter is used. You won’t be greeted with a strong whiff of lavender when you open the bag and your cat won’t be put off, but when they do nip to the loo, your house won’t be overcome with an unpleasant smell.

    The most common scents are lavender, pine and aloe vera so are all pretty natural and smells which your cat could easily come into contact with in the normal world or your garden.

    Things To Look Out For

    • Low Dust – Not only is the amount of dust caused by changing the cat litter alarming and potentially harmful to your respiratory system but if your cat scoots when they’ve done their business, it creates more dust which could be harmful to your kitty. If you’re concerned about this and the mess it could make, opt for a no-dust litter
    • No Tracking – Cat litter can stick to the paws of your kitty, which not only causes a mess on your floor but could also be harmful if they happen to lick it off when they’re cleaning themselves. Some varieties are better than others for no tracking

    Litter Buying Tips

    Cats can be creatures of habit, so don’t go switching between types or even brands. If your cat has found one which they like, swapping it out could mean they avoid using it.

    If you do need to change, ensure it is a gradual swap, and perhaps mix slight bits into their existing litter so they get used to the change in smell or feeling.

    Other Buyers Ask...

    Why should I choose non-clumping over clumping?

    While many people say that cats prefer clumping, and it can be easier for the owner to manage and clean out, clumping litter is often made from non-recycled materials which aren’t overly eco-friendly. It’s often not biodegradable either.

    Non-clumping litter is more likely to break down or turn into sawdust when wet. Many can be composted if they’re the right material, decomposing in the correct conditions which effectively leaves barely any trace on the planet.

    There is also generally more choice of materials and varieties in non-clumping, so if your cat seems to want to avoid clay or other clumping materials, it may be your best bet. Clay can also be dusty which is bad for humans or cats with respiratory issues.

    Cat owners need to think about the frequency in which they replace litter and how they dispose of it to cut down on landfill waste. Non-clumping also tends to be much cheaper which is good if you have a few cats and go through litter bags at lightning speed.

    Why do kittens need special cat litter?

    Cats can prefer finer-grain litter because it feels better under their paws, but this should be avoided for younger cats under three months old.

    Until they know not to eat their litter and they can use it properly as opposed to using it as a play centre or scratching environment, small particles can easily be ingested which could cause serious illness.

    How do I find the cat litter my cat likes best?

    Experts recommend leaving out a pan of different types of cat litter and allowing your cat the freedom of choice to see which they prefer.

    Cat litter is usually available in small bags for low costs, so once you have the variety and type down to a tee, you can try brands. Donate any unused to a local animal charity or try selling on an online marketplace if you need some of the money back.

    Where can I buy cat litter from?

    Our list features retailers such as Pets at Home, Jollyes, Fetch and Amazon if you want to order online. Most of the time, it can be delivered straight to your door and sometimes even on a repeat ordering system so you never run out.

    Price can vary between retailers. For example, we found that Amazon wasn’t usually the cheapest when it comes to cat litter.

    If you need some litter in an emergency case, most supermarkets such as Tesco, Asda, Aldi and Sainsburys will sell it, although you may not always get your kitties first choice which could cause a bit of a rift.
