What Is the Best Cat Litter in the UK?
There isn't one perfect litter for every cat. The best choice is one your cat is comfortable using, that controls odours, is easy to maintain and suits your household. For many owners, a good-quality, low-dust clumping litter offers a practical balance.
At Fussy Cat, our everyday favourite is Cococat Tofu Cat Litter, thanks to its lightweight plant-based formula, effective clumping and easy scooping. But some cats prefer finer granules, while others do better with a blended litter or a familiar clay texture. That's why we offer several alternatives.
Our advice: Start with your cat's preferences, not just the claims on the bag. A litter is only a good choice if your cat is happy to use it.
Why Choosing the Right Cat Litter Matters
Cats are naturally clean animals and can be particular about where they toilet. Texture, scent, tray size, cleanliness and location can all affect their willingness to use a litter box.
Look for litter that is comfortable under paws, produces little airborne dust, controls odours, forms manageable clumps if you prefer scooping, and is practical to store and dispose of. Unscented litter can be a good starting point for cats sensitive to added fragrance.
The Main Types of Cat Litter Explained
Clay (Bentonite) Cat Litter
Clumping clay litter commonly contains bentonite, which swells and forms clumps when wet. It remains popular because many cats are familiar with its fine, sand-like texture.
Advantages: Strong clumping, easy scooping and widely available options.
Drawbacks: Often heavy to carry, non-biodegradable and sometimes dusty. Dust levels vary considerably between products. Produced via strip mining, so poor environmental credentials.
Silica Crystal Cat Litter
Silica crystal litter uses absorbent silica gel granules to hold moisture and help manage odours. It is different from the fine respirable crystalline silica dust associated with industrial silicosis.
Advantages: Lightweight and often effective at absorbing moisture.
Drawbacks: Some cats dislike the hard texture; most products do not form scoopable urine clumps, and the material is not biodegradable. 10x more CO2 emissions emitted during production compared with Clay litter.
Wood and Paper Cat Litter
Wood pellets and recycled paper litter are made from renewable or recovered fibres. Many versions absorb moisture rather than forming firm clumps, although clumping wood products are also available.
Advantages: Renewable raw materials, often lightweight and available in low-dust formulations.
Drawbacks: Pellet textures can be unpopular with some cats, and non-clumping varieties need a different cleaning routine.
Tofu Cat Litter
Despite its name, tofu cat litter isn't necessarily made from the tofu you eat. It is generally produced from plant fibres such as pea or soy fibre, sometimes combined with starches or other plant ingredients. The mixture is formed into absorbent pellets that clump when wet.
Advantages: Typically lightweight, often low in dust, easy to scoop and made largely from plant-derived ingredients. Generally carries the lowest carbon emissions and smallest habitat footprint.
Drawbacks: Pellet size and texture may not suit every cat, and clumping strength and fragrance vary by brand.
Our Cococat plant-based tofu litter is a good place to start if you want to move away from traditional clay.
Cassava Cat Litter
Cassava litter is made using starch from the cassava plant, often in finer granules than traditional tofu pellets. Many formulations form firm clumps and are designed to produce relatively little dust.
Advantages: Fine texture, strong clumping in many products, and plant-based formulations. Generally carries the lowest carbon emissions and smallest habitat footprint.
Drawbacks: Fine granules may track on paws, and compatibility with automatic litter boxes depends on the particular product and machine.
For a cassava option, see Cococat Cassava Plant Cat Litter. It is designed for use with compatible automatic litter boxes; always check your machine manufacturer's requirements.
Mixed Tofu, Cassava and Clay Litters
Blended litters combine different materials to balance clumping, dust, texture and odour control. Some are entirely plant-based, while others include bentonite clay or activated carbon.
For example, pidan Cassava & Tofu Clumping Cat Litter combines plant-based granules and pellets. pidan 3-in-1 Blend includes tofu and bentonite clay. Check the ingredients before assuming that a mixed litter is clay-free or fully plant-based.
Cat Litter Comparison: Which Type Is Best?
| Type | Clumping | Dust | Texture | Main consideration |
|---|---|---|---|---|
| Bentonite clay | Usually strong | Varies | Fine granules | Heavy; mined material |
| Silica crystal | Usually non-clumping | Varies | Hard crystals | Absorbs moisture |
| Wood / paper | Often non-clumping | Varies | Pellets or granules | Renewable fibres |
| Tofu | Usually good | Often low | Soft pellets | Lightweight, plant-based |
| Cassava | Often strong | Often low | Fine granules | Tracking can vary |
| Mixed blends | Often strong | Varies | Mixed textures | Check for clay content |
These are general characteristics, not laboratory rankings. Individual products can perform differently.
Why Low-Dust Cat Litter Matters
Fine litter particles can become airborne when you fill the tray, scoop waste or when your cat digs. Dust can settle on nearby furniture and may irritate sensitive people or animals. Choosing a low-dust formula and pouring it gently can help reduce airborne particles.
Is Clay Cat Litter Safe?
Clay litter is widely used and is generally suitable when handled according to its instructions. Some clay products generate more dust than others. Prolonged exposure to high concentrations of respirable crystalline silica in certain workplaces can cause silicosis, but this should not be taken to mean that normal household use of clay cat litter carries the same exposure or risk. The NHS explains silicosis and its occupational causes.
For everyday use, a sensible approach is to choose a low-dust product, avoid creating clouds of dust while pouring, keep the tray clean and wash your hands after handling litter.
The Environmental Impact of Cat Litter
Cat litter materials have different environmental trade-offs. Bentonite clay is mined and is not biodegradable. Plant-based litters may use renewable crops or agricultural by-products, while paper and wood litters can use recycled or recovered fibres.
However, the overall footprint also depends on processing, packaging, transport, how much litter is used and disposal. Plant-based does not automatically mean impact-free, and biodegradable does not mean that used cat litter belongs in garden compost or the toilet.
Which Cat Litter Is Best for Your Cat?
Best Everyday Plant-Based Option: Cococat Tofu
If you want an easy-to-handle, low-dust clumping litter, our first recommendation is Cococat Tofu 100% Plant-Based Cat Litter. Its 2.5 kg / 6 L bags are convenient to store and top up, and the clumps are easy to remove during daily scooping.
It is particularly well suited to owners who want to reduce the weight and dust associated with some conventional clay litters. Cococat has also reduced the amount of added fragrance in its formulation, which may appeal to owners who don't want a strongly scented product.

Best for Fine Texture and Firm Clumps: Cococat Cassava
For cats that prefer finer particles, Cococat Cassava Plant Cat Litter is worth considering. It is also a potential option for certain automatic litter boxes, subject to the machine manufacturer's instructions.

Best Plant-Based Blend: pidan Cassava & Tofu
pidan Cassava & Tofu Clumping Cat Litter combines tofu pellets with finer cassava granules. It is a useful alternative if your cat is not keen on a purely pellet-based texture but you would still prefer a plant-based litter.
Best Hybrid Option: pidan 3-in-1
pidan 3-in-1 Blend Cat Litter combines tofu, bentonite clay and activated-carbon-infused tofu. It is designed for owners who want a mixed formulation, although it is not clay-free.

What Is the Best Cat Litter for Automatic Litter Boxes?
Automatic litter boxes often require a particular granule size, clumping speed and weight. Some systems work with fine clumping litter but cannot reliably sift larger tofu pellets. Others have different requirements.
Cococat Cassava Cat Litter is designed with Automatic Litter Boxes in mind but always check your specific machine's approved litter types before switching.
The Hidden Problem with Worn Plastic Litter Trays
Over time, plastic litter trays become scratched and become micro-porous. Those scratches may make the surface harder to clean thoroughly and inevitably retain unwanted odours. Stainless steel offers a smooth, non-porous, durable alternative that is straightforward to wash.
Our Fussy Cat Round Stainless Steel Litter Boxes are designed to be roomy, long-lasting and easy to maintain. The choice of tray can make cleaning easier, although good hygiene still depends on regular scooping and timely litter replacement.

How Much Cat Litter Do You Need?
Start with the depth recommended on the litter packaging. Many clumping litters work best with a consistent layer deep enough for your cat to dig and bury waste. Larger trays need more litter for the initial fill, but you can usually maintain the depth by removing clumps and topping up.
As a rough guide, the standard 45 cm Fussy Cat round litter box can take around 1½ bags of Cococat tofu litter for an initial fill, depending on the depth you prefer. Each Cococat bag contains 6 L. The amount you use over time will depend on your cat's habits and how frequently you scoop.
When comparing costs, look beyond the price per bag: consider bag volume, how much clean litter gets discarded with each scoop, and how often you need a complete change.
How Often Should You Change Cat Litter?
There is no single replacement schedule that works for every litter or household. Scoop solid waste and urine clumps at least daily, top up as necessary and clean the tray whenever litter becomes wet, dirty or smelly.
Cococat Tofu Litter with a Fussy Cat Stainless Steel Tray
With diligent daily scooping, regular top-ups and appropriate hygiene, some owners may find that a full litter refresh is needed only every 2–3 months. This is not a guaranteed interval: it depends on the number of cats, litter depth, usage and how well the remaining litter stays clean. Replace litter sooner if it becomes soiled, damp or smelly, and wash the tray when needed.
Other Clumping Litters
Remove clumps daily and follow the manufacturer's guidance for full changes. Many households replace the remaining litter every few weeks, although the appropriate interval varies.
Non-Clumping Litters
These often require more frequent full replacement because urine is absorbed into the litter rather than removed in clumps. Follow the product instructions and change it sooner if necessary.
In multi-cat households, trays usually need closer attention. A common starting recommendation is one litter tray per cat, plus one extra, placed in suitable locations.
Can You Flush Tofu or Cassava Cat Litter?
Many plant-based litters are marketed as flushable because their clumps can break down in water. However, that does not mean flushing is the best disposal method. Cat faeces, wastewater rules and the risk of blocked plumbing are important considerations.
We recommend putting used litter and cat waste into the appropriate household rubbish, securely bagged. Do not put used cat litter into garden compost intended for food crops. Always check the specific product's disposal instructions: Cococat Cassava, for example, is not intended to be flushed.
How to Switch Your Cat to Tofu Litter
- Start gradually: Mix around 25% of the new litter into your cat's existing litter, or offer a second tray with the new litter.
- Increase slowly: Over approximately 7–10 days, increase the proportion of the new litter if your cat is using it comfortably.
- Keep the tray familiar: Avoid changing its location and litter type at the same time if possible.
- Watch your cat: If your cat avoids the tray, return to a familiar texture and try a slower transition.
Sudden changes in toileting behaviour, straining or repeated unsuccessful attempts to urinate warrant veterinary advice; an inability to pass urine is an emergency.
Frequently Asked Questions
What is the best cat litter in the UK?
For many households, a low-dust clumping litter offers a good balance of cleanliness, odour control and convenience. Our everyday favourite is Cococat Tofu, but the best choice depends on your cat's texture preferences, any sensitivities and the type of litter box you use.
Is tofu cat litter safe for cats?
Tofu litter is safe for cats when used as directed, but plant-based ingredients are not automatically risk-free. A little extra care is needed with kittens to discourage eating litter, and seek veterinary advice if your cat repeatedly ingests it or shows irritation.
Is clay cat litter safe?
Clay litter is widely used and generally suitable when handled properly. Dust levels vary, so choose a low-dust product and avoid inhaling dust when filling or cleaning the tray. Industrial crystalline silica exposure should not be equated with ordinary household cat litter use.
Which cat litter produces the least dust?
Many tofu, cassava and specially processed clay litters are designed to be low-dust. The actual result varies by brand and how the product is transported and handled, so look for product-specific information rather than assuming an entire material category is dust-free.
Which cat litter is best for odour control?
Good clumping, sufficient litter depth, daily waste removal and a clean tray are all important. Tofu, cassava, clay and blended litters can each provide effective odour control. Strong fragrance is not a substitute for regular cleaning.
Is cassava cat litter better than tofu?
Neither is universally better. Cassava often has a finer texture and can produce firm clumps; tofu pellets can be lightweight and less prone to tracking in some homes. Your cat's preference and the performance of the individual product should guide your choice.
Can I use tofu litter in an automatic litter box?
Only if the manufacturer confirms that the machine supports that litter's pellet size, weight and clumping characteristics. Some machines work better with finer cassava or clay granules.
How often should I completely replace cat litter?
It depends on the product, tray, number of cats and how well the litter stays clean. Scoop at least daily, top up when needed and replace the full contents whenever the litter becomes dirty or develops an odour. Follow the manufacturer's guidance rather than relying on a fixed interval.
Final Thoughts: Choose the Litter That Works for Your Cat
The best cat litter should make life easier for you without compromising your cat's comfort. Clay remains a familiar option, while tofu, cassava and mixed formulations give owners more choice in texture, clumping and dust control.
For a lightweight, low-dust everyday option, we particularly like Cococat Tofu Litter. If your cat prefers finer granules, consider Cococat Cassava or a tofu and cassava blend.
