Description

A premium clumping cat litter made from the finest natural clay granules. Forms firm, easy-to-remove clumps when wet, keeping the remainder of the litter dry and clean for longer. Highly economical because only the soiled section needs to be removed each day.

Why it works well

  • Clumps firmly when wet, so soiled portions can be scooped daily without disturbing unsoiled litter.
  • Fine granules provide high surface area for better odour control.
  • Dry, clean litter remains in place for longer between full changes.
  • Economical in use — less wasted litter per change.

Features & specification

  • Clumping cat litter from premium natural clay.
  • Suitable for standard covered and open litter trays.

FAQ

How deep should I fill the tray?
Around 5–7cm allows proper clump formation and gives cats room to dig, which most prefer.

Delivered across the UK — free delivery on orders over £59.99.

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.

Shipping & Returns

Last updated: 16 August 2026

This policy explains how we process, dispatch and deliver orders, and what to do if something goes wrong.

1. Delivery charges

Delivery is free on all UK orders over £59.99. For orders below that value, the delivery charge is calculated and shown at checkout before you complete your purchase — you'll never be charged an amount you haven't seen first.

2. Order processing and dispatch

We aim to dispatch orders within 1–7 business days of the order being placed. Business days are Monday to Friday, excluding UK public holidays.

Once your order has been processed you'll receive a confirmation email, followed by tracking details where available.

5. Tracking your order

Once your order ships, we'll email you tracking information where available. You can use this to check the live delivery status directly with the carrier.

If a package is confirmed lost or significantly delayed by the courier, we will send a replacement or issue a refund.

7. Incorrect delivery addresses

Best litter ever

Clumps really well, so there's very little waste. Has no smell, but covers urine and poo smell fantastically. 5 stars is not enough.

K
Kim
Technically clump, but not very well.

The sand does clump in the litter box but the clump stays very wet and difficult to scoop. The moment you scoop, it falls apart into small wet smelly pieces and takes ages to remove. Since the pee stays wet, the litter box itself is also smelly even after cleaning. Might be suitable for one cat that doesn't pee very much but otherwise, very disappointing and I will not repurchase.

Catsan (not so) ultra clumping

I have 8 cats and couldnt get my usual tigerino so had to try this based on the fact there was no fragrance and is meant to clump! I'd say less clumping and more of a sticky mess! It's also quite heavy when wet. It's significantly more expensive and definitely not as good as tigerino. Will avoid in future.

O
Olivia
Simply the best

Simply can't fault it. Clumps really well, dust-free, and covers smells too if the tray is full enough.

Worst clumping litter ever

This is the worst clumping cat litter I’ve ever used, it’s didn’t clump or contain smells, just a complete waste of money. I will not purchase this ever again

Very happy

Really pleased with this litter. Covers urine well and my cat seems happy with it.

Not for cat with floofy paws!!!

Had to get this for the two Ragdolls as the normal non-clumping litter was out of stock. It’s like sand, it clumps well but it was spread absolutely EVERYWHERE thanks to the floofies!!!! 🙀

CATSAN CLUMPING

Very good, easy to clean & dispose of

Best cat litter

Best I’ve ever used, clumps wonderfully. No smell. Tracks a little.\nBuy regularly now.

Isla
Good

Used this for years and great clumping and odour control. Disappointed no longer able to get 15l bags. The economy pack of 2 x 3 is a rip off cause you then get charged nearly £3 for extra weight.

Amazing stuff

Love this litter! Works great with my Litter Robot Connect 3. ❤️

Good clumping cat litter

The clumping catsan is really good for one of my kittens that only buries her business:)) but my other cat digs a lot before he wees so all the liquid goes on the bottom of the box and I have to scrape it with the scooper which is not an easy task ,plus, when he goes back and starts digging all the clumping spreads into small pieces ,so it makes it really messy. It does not cover the odours very well so I still need to use a felight spray which does the job . Will go back to the nonclumping one.

Less tracking

We’ve been using this litter for years. Multi cat house but only two use the tray. It only tracks a couple of feet from the tray so easy to vacuum up. Rarely sticks in paws cos it’s small granules. I’ve recommended to friends and they’ve always moved to it after trying several other (cheaper) types.

Sonia
Best Litter I've used

Well priced, minimal fall out, scent free. \nI was hesitant to purchase based on reviews but upon using this product I am thrilled. Clumps well, great quality. Kitten and cat both are unable to launch this litter the way they have for others.

A
Adriana
Really good

After reading a few of the reviews I wanted to write myself and let everyone know that this litter is amazing. At least for my baby Ragdoll. He loves it. We used the non clumping one and it was getting everywhere. And the smell was bad. \nWith this however everything changed. Easy to clean and the smell disappeared. Love it!

Eli
Awful smell

This is the worst litter I have ever tried. After only 1 day it smells like something rotten. I even thought there was a rotten animal or something in the litter. After 3 days of use also my cats smell of rotten creature and the house. I think I'll throw away the rest of the bag and never ever buy again. and it's not that I don't clean it I scoop even twice a day. It's just horrible

J
Jacqueline
Gets everywhere!

Too small, gets stuck to the cats paws, legs, bums, and is all over the house.

T
Tatiana
Fine texture

My cat really likes this one, and so do I. The texture is very fine, like sand. It doesn't get caught in my cat's paws and it doesn't track around the house. It clumps nicely and it is easy to clean the tray.

K
Kate
Finally one that doesn't track too much

I have had a multi-cat household for years and with that have tried nearly every litter. My quest has been to find a good litter and one that has reduced tracking across my floors. This is by far ahead of the others. I think it is fair to say it's impossible to have zero tracking with any litter, but this has been the best. I only have to clean a small amount outside of the tray whereas other litters would end up all over the house.

Cats Love it. I Don't

It's hard to be objective about this cat litter. When I first got it, the cats loved it, and it does clump beautifully. I was delighted. But very soon the reality cept in. This litter is made from very small, but fairly round, bits of material. When the cats jump out of the litter boxes the take a good bit of it out on their paws and on a hard surface it spreads all over the place in no time. I have hard wood floors in part of the house, and tiles in other parts, and it is sore on the feet
