Our litter is made from 100% PEFC-certified, recycled wood materials, a by-product of the timber industry meaning no trees are felled in the making (YAY!).
Not only is it 100% biodegradable, but it's also highly absorbent and clumps each time your cat uses their tray.
What does Natusan smell like?
Our litter is 100% natural with no added fragrance or nasty chemicals and smells similar to freshly cut wood. Delightful!
If you know your cat can be fussy with their litter tray, it’s best to take a slow and steady approach when switching their litter. We recommend a gradual changeover by mixing a small amount of Natusan in with the current brand every day for several days. This changeover should typically take place over three to five days

*Note: for Collect & Compost customers, we’re unable to compost any external debris, so the litter used in the initial changeover should be discarded in the domestic waste.
We recommend a two-inch layer of litter covering the entire tray. This will give your cat enough room to dig with adequate covering afterwards. All cats are different, so it’s important to pay attention to your cat's litter tray habits to see whether you need to adjust this level up or down.
Ideally, you should remove the clumps from your cat's litter tray as and when they appear, however we know that’s not always possible. At the very minimum, the clumps should be removed daily.
Our litter is made from 100% PEFC-certified, recycled wood materials with no added fragrance or nasty chemicals, however, it’s best to check the guidelines set by your local council when it comes to garden waste and composting.
Although Natusan is 100% biodegradable and compostable, we do not recommend that you compost it at home. This is because most home composting systems do not reach the temperatures required to reliably kill all bacteria, and/or parasites, potentially contained in soiled litter or faeces.
Natusan is made from 100% PEFC-certified, recycled wood materials and dissolves entirely in water, however, we recommend that you check with your local wastewater service provider before flushing the clumps down the toilet.
Cat faeces actually makes great compost. It provides an excellent source of nitrogen, phosphorus and potassium for plant nutrients and is perfectly safe to use. The method that our composting partners use is very different from the way that we compost at home. In-vessel composting is treated on an industrial scale where it reaches a minimum temperature and is held in order to kill even the most resistant bacteria.
On top of that, it is mixed with the correct co-products, which in turn produce a better quality fertiliser. We work very closely with our composting partners who are compliant with EU Regulations and certified under the waste regulations in England and Wales.
Our litter works very differently to the non-clumping kind most people use. It’s not only 100% biodegradable, but it’s also highly absorbent and clumps each time your cat uses their tray. Removing the clumps is easy, and because you’ll only ever leave clean litter behind, you’ll find the overall tray will stay much cleaner for significantly longer.
Yes! Even without subscribing to our Collect & Compost service, by simply switching to Natusan 100% biodegradable clumping litter you will reduce your cat litter waste by a whopping 65%!*

It’s common for kittens to explore their surroundings with all senses, including taste and while Natusan is safe for cats of all ages, it’s recommended that your kitten is weaned before making the transition, usually this is around 12 weeks.
When pregnant, we recommend that you follow the advice provided by the NHS, which is not to empty your cat litter tray but if possible, get somebody else to do this for you. Alternatively, if this is not an option, you should wear disposable rubber gloves and wash your hands thoroughly afterwards.
After the Natusan Tray has been fully assembled, the dimensions are L 54.5cm W 36cm H 41cm.
Absolutely! Our litter can be used in any type of tray, including self scoop robot trays.
When switching from non-clumping litter to Natusan, a little goes a very long way! For example, one 10L bag of Natusan will last around four weeks for an average small-medium indoor cat. Of course, we understand that every cat has their quirks, and all households are different, so our friendly Customer Care team is always on hand to offer bespoke advice based on your current litter type and volume. You can either drop us a note at or call us on 020 3389 9331, any working day between 9:00 a.m. and 5:00 p.m.
**It’s also important to note that not all cat litter brands include the initial tray fill in their consumption calculations.

Most mineral clumping litters are made of, or at least contain, bentonite. This clay mineral can be quite heavy at approximately 1kg per litre.

Natusan is made entirely from natural wood fibres and does not contain bentonite, when compared to a mineral based litter, it’s much lighter at around 330g-480g per litre.
Natusan is organic clumping litter made from 100% natural wood fibres and DOES NOT contain Bentonite.
At Natusan, we are stats people! We find that using statistics is a great way to explain some of our key benefits to our website visitors. We could tell you that you will reduce your cat litter waste by switching to Natusan, but we understand you'll want to know by how much compared to the waste your cat litter creates today.

We also understand that you will want to know where these claims have come from and check that they are truthful. That's why we will always add an asterisk when we make a claim on our website.

Whenever you see an asterisk, it means you will be able to find further information on that claim on our T&Cs page. We pride ourselves on transparency so if you would like even more information, our Customer Care team are more than happy to talk you through the detail behind these claims on the phone or by email.
