Description

Pellet-format litter made from 100% natural active wood fibres, designed specifically for long-haired cats — the smooth pellet surface means they don't stick to fur or paws the way fine-grain litters can.

Why it works well

  • Soft clumping: the pellets form gentle clumps that are easy to scoop without crumbling.
  • Active wood fibre technology permanently binds odours and moisture rather than just masking them.
  • Biodegradable and compostable — can be flushed in small amounts or composted (check your local guidance).
  • Non-sticky surface, so cats with long fur track far less litter out of the tray.

Features & specification

  • 100% natural active wood fibres, no synthetic additives.
  • Pellet format — easier on paws than fine grain, and gentler for declawed cats.
  • Biodegradable and compostable.

FAQ

How often do I need to change the litter completely?
Remove solid clumps daily. A full tray change is usually needed every 3–4 weeks for a single cat, though this varies with tray size and usage.

Will this work in an automatic litter tray?
Check your tray's manual first. Many automatic trays are designed for fine clumping litter and the pellet size may not suit them.

Care

General Care & Storage
To get the most out of your Petszo delivery, please keep the following in mind:

  • Edibles: Keep food and treats tightly sealed and stored in a cool, dry environment.
  • Fabrics & Beds: Gently wipe clean or wash at 30ºC (always check the individual label first). Do not bleach.
  • Safety First: Regularly check toys and accessories for damage and remove them if broken.
  • Note: Always refer to the specific packaging for exact instructions.

Getting the most out of your Petszo order comes down to storing things properly and checking them regularly. Here's what matters.

Food and treats

Keep dry food tightly sealed in a cool, dry place away from direct sunlight. Resealing the bag or transferring it to an airtight container helps stop the fats going stale, which is the usual reason a dog or cat suddenly goes off a food they previously liked.

Opened wet food should be covered and refrigerated, and used within about 24 hours. Serve it at room temperature rather than straight from the fridge — cold food is noticeably less appealing to most pets and can be harder on sensitive stomachs.

Many treat pouches contain a small oxygen absorber sachet to keep the contents fresh. This isn't edible — remove and discard it before giving your pet the treat.

Beds, blankets and fabric items

Most fabric items can be gently wiped clean or machine washed at 30°C, but always check the individual care label first — padding and covers vary between products. Don't use bleach, as residue can irritate skin and paws.

Removable covers are worth washing more often than you'd think, particularly for pets with skin sensitivities.

Toys and chews

Check toys and accessories regularly for damage, and remove anything that's cracked, split or losing pieces. Small fragments are a genuine choking and blockage risk.

Always supervise your pet with chews and rawhide products, and take away any piece small enough to be swallowed whole. Match the chew size to your pet — a chew intended for a small dog won't last long with a large one, and creates more risk.

Harnesses, collars and leads

Check the fit periodically, especially on growing puppies and kittens. As a rule you should be able to slide two fingers comfortably under any strap — tighter risks rubbing, looser risks your pet backing out of it.

Inspect stitching, buckles and clips for wear, and replace anything showing damage before it fails on a walk.

Litter trays and small pet enclosures

Scoop clumping litter daily and top up as needed; a full change every 1–2 weeks is typical, more often with several cats sharing a tray. Clean the tray itself with hot water and mild detergent rather than strong disinfectants, some of which are toxic to cats.

For small pet enclosures, spot-clean soiled bedding daily and do a full change weekly.

Switching foods

Introduce any new food gradually over roughly 7–10 days, mixing increasing amounts into the current food. Sudden changes are one of the most common causes of digestive upset, and it's easily avoided.

Always check the product packaging. The guidance here is general — individual products carry their own storage, washing and feeding instructions, and those take precedence. If you're unsure about something, or your pet has a specific health condition, speak to your vet.

Delivery

How long will my order take to arrive?

We aim to dispatch orders within 1–7 business days of you placing them. Delivery time after dispatch depends on the shipping method chosen at checkout. You'll receive tracking details by email once your order is on its way, so you can follow its progress with the carrier.

Do you offer free delivery?

Yes — delivery is free on all UK orders over £59.99. Orders below that threshold are charged at the rate shown at checkout before you pay.

Where do you deliver?

We currently deliver within the United Kingdom only. We don't ship internationally at present. Please note that a small number of items are shipped from outside the UK and may take a little longer to arrive — this is noted on the individual product page where it applies.

What if my order is late?

Carrier delays occasionally happen, particularly around public holidays or in bad weather. If your order hasn't arrived within the expected timeframe, get in touch with your order number and we'll chase it. If a package is confirmed lost or significantly delayed by the courier, we'll send a replacement or issue a refund.

How do I track my order?

Once your order ships, we email you tracking details. Use these to check live delivery status directly with the carrier.

Returns & refunds

Can I return something if I change my mind?

Yes. Under UK consumer law you have 14 days from receiving your order to tell us you'd like to cancel, and a further 14 days to send the items back. Items need to be unused, in their original packaging and in the condition you received them. Return postage for change-of-mind returns is at your cost. Full details are in our Refund & Return Policy.

What if my order arrives damaged or incorrect?

We'll put it right. Under UK law you have up to 30 days to reject a faulty item for a full refund. For transit damage, contact us ideally within 48 hours of delivery with photos of both the item and the packaging. We cover return postage on faulty or incorrect items and will offer a full refund or a replacement.

Are there items I can't return?

For hygiene and safety reasons, opened or unsealed pet food and treats, used grooming products, personalised items and gift cards can't be returned unless they're faulty.

How long do refunds take?

Once we've received and inspected your return, we'll let you know whether it's approved. Approved refunds are processed within 14 days of us receiving the goods, back to your original payment method.

Can I cancel an order before it ships?

Yes — email support@petszo.co.uk with your order number any time before dispatch. If it's already gone out, you can return it under the 14-day change-of-mind period once it arrives.

Products

Do I need a prescription for veterinary diets?

No prescription is legally required in the UK to buy veterinary diet foods. However, these products are formulated for diagnosed conditions, so we strongly recommend speaking to your vet before starting one — and having your pet checked at least every six months while feeding it. If your pet's health worsens, seek veterinary advice straight away.

How should I switch my pet to a new food?

Gradually, over roughly 7–10 days. Mix a small amount of the new food into the current one and increase the proportion each day. Switching abruptly is a common cause of digestive upset.

How do I store pet food once it's open?

Keep dry food in a cool, dry place, ideally resealed or in an airtight container to stop the fats going stale. Opened wet food should go in the fridge and be used within about 24 hours. Always check the individual packaging, as some products have specific requirements.

Declining Quality

I had been using this product for few year and was initially very satisfied with its clumping ability and the fact that it is environmentally friendly and flushable. However, now its clumping ability is next to nil. At best you are left with a mound of soggy saw dust which has become very difficult to scoop out without wasting a lot of the product.\n\nI used to recommend this product to friends but sadly I have now had to switch to a litter which contains clay but has excellent clumping ability.

N

Pellets are way too big

The pellets are way to big, become hard to clean without wasting a lot of litter and trail when the cat get out. \nIt also doesn't really cluster on poo. \nI used to love this brand, but it's really not up to par anymore.

L
Lee
Clumps Well But Too Much Dust

This cat litter clumps well but there is alot of dust that collects under the pellets. This can cause irritation to a cats respiratory tract & possibly trigger asthma attacks, as my cat on occasions does have a coughing fit. To prevent this the larger pellets need to be sieved before being placed it into the cat tray. This should have been done during the manufacturing process before its packed.

G
Gloria
The product seems good but my cats hate it

A friend recommended this cat litter and I saw a lot of good reviews, but unfortunately my two cats refuse to use it, so it's been wasted money!\nGreat packaging from PetsZo though, hence the 4 stars

Stops dust tracking and more hygienic as can scoop pee out in clumps. Pee doesn't just sit there ...

Absolutely brilliant! Stops dust tracking/little bits as its pellets so if any come out they are only around the tray not the whole house, and more hygienic as can scoop pee out in clumps so it lasts ages as no litter soaked in pee sitting at the bottom of the tray smelling like what happens with none clumping.

Big drop in quality!

This used to be really good, large pellets, no mess, but over the last few months the quality has dropped massively. Lots of saw dust , creating more mess . Won't be buying this anymore unfortunately.

R
Rita
The formula has changed

This was my go-to litter for many years, but they recently changed something in the formula. The new formula is much dustier, doesn't clamp as well, and the pellets are smaller and darker in color. Shame!

Excellent cat litter

This isn’t the cheapest of cat litters but I feel it’s worth the money as it clumps well and there’s no tracking. I’ve used it for decades as it’s the best litter

P
Privat
Very good

I've been using this litter for a few years now. Before that, I tested loads of different ones across all price ranges. My tomcat used to scatter everything across the hallway and kitchen. I had to clean up after him every single time. With the pellets, the cleaning has come to an end. At first, my cat found the litter a bit strange, but after a day, he started using it normally. Occasionally, 3-4 pellets end up outside the litter box, but that's nothing compared to before. I'm sticking with it, and my flat doesn't smell either. Unfortunately, it's quite pricey.

H
Henry
Our bedding

For my cats and me, this is the best litter so far – hardly any smell, doesn’t spread around the house, and doesn’t stick to their paws.\n\n,Cons: You end up removing quite a lot when clearing out the clumps, and the clumping quality varies depending on the batch (it always clumps well, but sometimes the clumps crumble a bit).

V

Used to be very good.

It used to bind urine very well and didn’t stick to the fur. Unfortunately, the pellets now crumble after a very short time. In that case, you might as well use the regular Cat's Best. Although, sadly, that no longer matches its previous quality either. I’ve now completely switched brands.

Product has changed!

I have been using these pellets for years and years. Everyone who comes to mine always says you can never smell cats or cat litter and I always refer them to this brand. However, over the last few months, this cat litter appears to have had a change. The pellets do not clump the same anymore, the litter is darker in colour and the quality just isn’t the same anymore. I have sadly had to find and source an alternative. Such a shame as I loved this once upon a time

Getting worse again

The litter has gotten worse again. \n,It no longer clumps. \n,The quality of Cat's Best is very inconsistent. \n,With the high price, you'd expect better. \n,I'll give it one more try now. \n,Otherwise, I'll switch to a cheap brand.

Significantly worsened...

For several months now, the previously great product has significantly deteriorated! The pellets are smaller, crumble easily, and turn into powder in the litter tray. They scatter everywhere again because they’re much lighter than before. They form poorer clumps, and the smell of urine appears much faster! None of this used to happen before. So why has a great product been made worse?? This is very frustrating...

M
MGN
Not as good anymore

The past 2 bags have been disappointing and no longer clump properly leaving bits of dirty litter throughout the tray. Which means it is smellier and messier than in the past as you can’t riddle it properly. Cancelling my subscription and going back to the old Cats best. Shame as this used to be better with less tracking but not worth the extra money anymore.

Best litter

Top. Clumps well, easy to clean. With many types of litter, I often felt it smelled like urine. With this one, I have to say, it's almost unbelievably odourless. Our tomcat took to it straight away.

Search for the perfect litter finally over!

For the past six months, I’ve been ordering the Smart Pellets from Cat’s Best every month, and I have to say, no more litter around the flat, no more litter in the bed. It’s very easy to clean up if a few pellets end up next to the litter box after use! I used to have the regular clumping litter from Cat’s Best, but these pellets are simply even better. My darling Timmy and his mum are completely satisfied and much more relaxed since I’m no longer swearing and complaining about the mess 😊🐈.

G
G.A
Very satisfied

I’ve tried various types of litter from Cats Best, and for me, it’s clear—the pellets are the best! They clump urine well, don’t smell, don’t create dust, and hardly get tracked out. The other types either smell, don’t clump properly, or are dusty, so they’re not as advertised.

Quality has dropped

My cat has been using this cat litter for a few years. I have always been very pleased with this product; it's eco-friendly, clumps well, and has no odor, though it's expensive. However, the quality has dropped a lot in the last few months. Pallets at the bottom of the bag, comprising at least one-fifth of the bag, are like sawdust!
