Changed formula
What has happened to this litter? The litter has changed the grain is now much smaller so creates so much more mess. Also more dustier . Not great

Rubbish
Worst litter I've had. Thought I try it because of the good reviews. It did not clump, it was just a soggy mess. It's the worst litter for tracking (could be because the cats are huge 22lbs.,). Even when new I still had to follow with the hoover. Would not buy it again.
Litter is good, but packing is nearly broken
Litter is good, used for many years already. But Zooplus's packing... I can't say it really bad, because the paper bag have 3 layers. But outer 2 layer already broken, luckily the last layer is strong enough... So everything still inside paper bag. And the outer delivery box is totally fine. So I only can guess is Zooplus's packing issue... Or their storage issue?

The Worst Cat Litter Ever!
Purchased this when it was on offer due to the rave reviews.
It is by far the worst litter we have EVER tried. It did not neutralise any odour at all. The litter trays were stinking after just a day. The whole of downstairs smelt like a month old warmed up wee ridden litter tray!
It also tracked around the whole house, even made it into our bed! Constantly having to vacuum!
Couldn’t take it, had to throw the lot in the bin as the smell and additional housework were making me ill.

Very messy
I wanted to try this as its economical but it sticks to my cats feet and walks through the house. It also clumps really badly. I’m going back to my old make but am really disappointed.

Product is no longer as good as it was
I've been using this litter for years but have watched it go downhill in quality for the last couple of years. It used to clump but now all it makes is a horrible slimy mess and no longer seems to cover the smells as it used to. Have now found an alternative corn based litter which clumps properly and smells much better. Cheaper too! I used to swear by Cat's Best but now I can't wait for my last big bag to run out.

Appalling
I must be the only person to be unhappy with this
I bought 2 bags last week and have already had to use them both up. I’ve had to changed the litter daily due to the smell. Literally absorbs nothing and the poo is just a sticky mess that sticks to the cats paws.
I am so disappointed I wasted my money
Vile

I'm done with this litter
I don't even know why I bother with this anymore, it tracks absolutely EVERYWHERE and is so dusty. This is my last bag.

The worst cat litter ever!!!
Do not buy this cat little unless you are happy with having to litrally scrap it of the bottom of the tray when it come to changing it, even with that and socking it didnt remove it completely have had to buy a new tray, in a nut shell it is over priced sawdust!!!!

DO NOT BUY
I would give it zero stars if i could! I hardly write reviews but thought i had better warn others as this is by far the worst litter i have ever bought - it gets stuck and the cat trampled it all round the house. Bits of it got everywhere....this has never happened before.
For the price i would have expected something far superior. It was fairly absorbent - thats the only positive i can muster.
NOT CLUMPING - Don't waste your money. Try something else if you want clumping litter.
If you're reading this, then you are in the position I was a week ago. Unsure - but hoping the reviews might give you some insight into whether this would be a good purchase or not?
I saw mixed reviews. However, I saw a running theme stating this product does not clump. It's not working, it's a waste of money. ALL of these reviews are correct! This product is waste of money. It does not clump and breaks into pieces when you try to scoop it out. Meaning you get tiny 'dirty' bits everywhere.
Dusty
This was an amazing litter, but since the new design the dust has become so bad it makes me cough when I clean out the tray. This cannot he safe for the cats. Really disappointing.

Disappointing
Having read a rave review for this product I was sorely disappointed with it. It is light which for clumping litter is unusual but as a result does not clump effectively and my cat who likes to cover up distributed lots of it outside the tray despite having a cover. It does deodorise well but in many respects it is no better than much cheaper supermarket brands.
Formula change a disaster
Please, please, please bring back the old formula! Whatever you've done just doesn't work! I fetched an old bag of litter from my parents (whose cats now toilet outside) and it may as well be a completely different product! The new stuff just doesn't clump at all and tracks everywhere. It's so dusty all the cats sneeze when they come out the tray.
very poor quality
it smells bad, not clumping at all even if, it is still very soft and easy to spread all over a cat litter.

Mrs
Worst litter I have ever used in forty years of having cats.
Does not clump effectively and cat scatters it all over the floor.
Would not recommend product.

"New Design same Quality" what do they mean??
Unfortunately the formula for this product has dramatically changed "New Design" they say same quality, I think not more like old fashioned fullers earth not like the original OKO PLUS before it changed to Cat's best, now cheaper ingredients same high price
disappointed not as per the original item
Litter clumps disintegrate!
Unfortunately the latest bag I purchased doesn't clump very well and the clumps disintegrate and mix into the fresh unused litter making it very difficult to scoop out. Previously it clumped into balls which stayed clumped together and easy to scoop. My kitten won't use this batch of litter unless I've cleaned out the disintergrated clump/clumps so I'm having to use 2 litter trays just in case kitty won't use it. It's a shame as I thought this was a great litter. Maybe this is just a one off?
What on earth have they done to this product?
This used to be a brilliant cat litter, now it's rubbish. Used to clump, now it just disintegrates into crumbs that are impossible to scoop out and tracks everywhere, even out of an enclosed tray. Used to mask smells really well, now does not. I can only think the reason for this change of formula is the usual one of a company shooting themselves in the foot in the relentless pursuit of cost cutting with cheap ingredients - and losing sales. They've certainly lost MY custom.

Was premiership level, now Sunday league
With 2 young ragdoll boys, found this litter perfect for the job of clumping well, preventing any bad smells and lasting very well. But WHAT have they done to the formulation. It’s useless at clumping up wees and mixes too easily into the unused litter, smell retention is measly. I would urge that Zooplus contact the manufacturers to find out if, why, when they changed the “magic recipe” and show them all of the recent reviews to see if they can change it back.

Cats Best Original litter
I've been using it for 12 years, it used to be the best litter, but now it's a disaster, just dust, it's no longer granules like it used to be. I'll never buy it again!

Terrible drop in quality
Used to be the best cat litter, I bought it for over a dozen years, but for the past few months the quality has clearly dropped, and since September 2026 it’s just a disaster—different colour, different smell, loads of sharp bits that get stuck in my cat’s paws, it’s dusty, and it doesn’t clump. I made a complaint about one pack and big thumbs up to Zooplus for sorting it out, but unfortunately the problem keeps happening with the next deliveries. The smaller packs (ordered to try) are just as bad, unfortunately.

Cats Best Original litter
It used to be my favourite, but now it's not worth the price. It doesn't clump well and falls apart when you try to move it to the toilet. Clearly, the manufacturer tried to cut costs, but being stingy ends up costing you twice…

All my animals developed respiratory symptoms from it – dangerous
There were probably fungus spores in this bag. I bought it a while back when I still had some of the other one left, so we only started using it recently. But once we did, about a week later, first my smaller cat started sneezing and had watery eyes, then the bigger one started coughing badly. I changed all the litter to tofu because I thought it was just the dust... but there was a bed where this stuff was stuck, and when my dog sniffed it and immediately started choking, that's when I realised this must be the cause. Only a few litres are missing from the whole bag... I'm furious.

The quality dropped a lot since September (at least for the 40-litre)
It seems this is a new batch and they've made changes to the product, which has ended up making it one of the worst I've ever used.
Even its appearance has changed: it used to be light-coloured and yellowish, but now it's kind of grey.
The price had already gone up quite a bit, but we kept buying it because it was the best for what we needed it for. Unfortunately, with these latest changes, they've completely ruined it.

Terrible, it used to be great but now it's really bad and even more expensive
I used to use it over 5 years ago but I won’t buy it anymore. I’ve given it several chances and it just keeps getting more expensive and the quality is really poor. IT DOESN’T CLUMP AT ALL. I’m switching to another brand. Farewell, CATS BEST.

Getting worse every time
It used to be really good, but it's getting worse every time—they don't clump at all anymore, and on top of that, it's getting more and more expensive. I've given it several chances but it just keeps getting worse, I won't be buying it again.

Extremely poor quality
I was always satisfied with Catsbest cat litter. The last two batches I ordered in September 2026 are the worst quality litter I’ve ever received. I contacted customer service because of this. It doesn’t clump, even after hours, and spreads all over the litter box. I changed it three days ago and will have to replace it completely again in the next few days because the urine clumps are spreading everywhere and it’s starting to smell. Something really needs to be done about this.

I won't buy it again
It used to be good years ago, but now it's ridiculously expensive and the quality has dropped so much that it smells bad, doesn't clump, and turns to dust by the second day. My cats don't want it anymore and I'm not surprised. The whole house smells awful and that's another customer they've lost.

‘Clumping’ litter
A bit like porridge oats mixed with Portland cement. The clumping is just a mess.

Cat's Best Litter
I bought this litter on the recommendation of friends who use it and praised its quality a lot. Unfortunately, for me and my cats, it turned out to be a nightmare. The litter was tracked not only all over the bathroom but throughout the entire flat, even though I had a special mat in front of the litter box. It looks like oat flakes and even behaves similarly when it gets wet. It doesn’t clump; yes, it forms a ball, but it’s muddy. It sticks to the bottom of the litter box and falls apart when the cat digs in it. I do not recommend it.

Quality has dropped a lot
I've been using this litter for four years and was always happy with it. It used to clump well, lasted ages, kept the smell under control, and didn't create any dust. But now it just has an unpleasant smell, even if you sift the tray every day and add fresh litter. When you fill it up, it gets dusty, and the clumps fall apart when you sift them. After only a short time, the tray is more dust than litter. Unfortunately, I really can't recommend it anymore.

Quality suddenly dropped
Our first packs were really impressive. These days, we steer clear of it. Unfortunately, it absolutely reeks, makes a huge mess, and it doesn't clump anymore either. There are much better alternatives out there!

Declining quality
I've been using this litter for over 10 years. The last two bags, though, the quality has really gone downhill. The litter is darker now and much less absorbent. The clumps fall apart and dirty the rest of the clean litter, which makes it smell bad really quickly. Not great for automatic litter boxes. Time to look for an alternative.

It's not the same anymore
I’ve seen that other people have had the same experience as me.
I bought it for two years, it was really excellent.
For months now, it’s not the same anymore.
It DOESN’T CLUMP anymore.
As for the smell, unfortunately I’ll have to try again because I bought a similar one, but the bad odour isn’t neutralised.

Clumping litter???
I bought this litter because it was supposed to be very low in dust. But that's really the only advantage! As for CLUMPING litter...???? Every clump falls apart as soon as you lift it out of the tray, or even just shake it a bit on the scoop to let the clean litter fall back into the tray. So better not to shake it and just throw everything in the bin. What a waste!
Even my three cats prefer to use the other tray, which still has the "old" type in it.
Never again!!!!!
