Worse cat litter ever!!
This litter is a total nightmare, it literally gets tracked everywhere and I mean everywhere. Have never used a worse litter. I can’t comment on whether it’s actually any good as I binned it after 6 hours as I couldn’t cope with the tracking. Back to tigerino

What's Happened?
used to use this a lot but recently seems to have changed. smells bad, no longer clumps properly and seems to be made differently. used to be made of wood pellets and it smelled like fresh sawn wood now it just crumbles to dust and smells horrible. Won't be buying any more
Awful Cat Litter
I bought this to try after reading reviews.
It smells awful like urine all the time the worst thing is it tracks all over the house from my 3 cats so is really messy.
Unfortunately I bought 40L so a total waste of money and not cheap.
When used will go back to my clay clumping litter.
Dissapointed
Have used this litter for ages, now it has changed, doesn't clump as well and turns to dust. Use to be great value not now. Will now have to find another litter.
|
Never again
So we thought we’d try a new litter for the cats, what a disaster!
It smells awful all the time even when cleaned out, gets absolutely everywhere And we are using more than we ever did!!
Back to the trusted Biokat we go!!

Changed formula?
Can only agree with other recent reviews. The last bag was terrible, it doesn't clump and the wet litter disintegrates into the clean so you need to use twice as much. This has suddenly made it very bad value where it used to be good value. I have requested a refund and will not buy again unless Zooplus confirms that the previous formula has been reinstated.

What’s changed? Last 2 bags have been terrible?
I usually purchase the 40L bags, as I have 2 indoor cats. The last 2 have been terrible:
🔹More dust
🔹Less absorbent (breaks up)
🔹No longer contains odor
🔹Tracks more
The first time I thought perhaps it was the bag, or how it had been stored, but twice!
At the time of posting this GB was in the middle of a heatwave of 30°. I’m wondering if the climate is having an effect. I’ll try 1 more bag, and if it’s the same, I’ll be looking to change products.

Not what it used to be
We have always used this for our cats as it was the best litter we had tried but the last 2 bags haven’t been the same. It doesn’t clump well anymore and it doesn’t hold the odours in. Don’t know why they changed it. Now I have to find another litter for my kitties. Has anyone found anything to replace this yet?
Doesn't clump anymore
I used to love this product and also recommended to any friends with cats.
However, the last two bags have been very different. It does not clump at all anymore. All the contaminated bits of litter us spreading out to the whole tray meaning I now need empty it more frequently.
|
Not what it used to be
We've used for years now and found it a great performer, and flushable too! However, the last couple of bags have been a let down as it now seems to be so dusty, tracks worse than it ever did and just doesn't clump particularly. We have finally decided to let it go and find an alternative product.

This litter used to be excellent thus I have used and recommended it for 12 years. However the last bag has litter in it of very poor quality: it no longer clumps and does not disguise the smell of cat urine any more. I am really disappointed with the drastic drop in quality

Doesn't clump anymore
Lionell & Co
as with many other reviewers I bought my last batch about month ago. As they have all indicated something has changed. This no longer has the great clumping ability it once did. Cats Best was my first choice litter, and it will be difficult to replace for another as good as "oko". I will maybe think outside the litter box and buy this and the pellets to see if that sorts the issue. If not, mmmmm.....???
Doesn’t clump anymore
Has stopped clumping. Doesn’t last up to 8 weeks as advertised. More like 2 because of the amount of contaminated litter that you can’t scoop out.

Somethings changed and not for the better
We have two British Blue cats that use the same litter box. They aren’t fussy cats and have used all the litter products without a problem in their owner’s pursuit of the ‘perfect litter’.
We’ve used Oko Plus before, thought it was good, a little tracking but manageable ... until this last order. Have they changed the product, it doesn’t clump at all, the wee balls break up when I try and get them out of the box. I won’t buy it again.
Doesn’t clump any more
Rubbish. Used for years and been fine. Now they have changed the formula and it rarely clumps
|
Change of formula?
I’ve used this cat litter for 10+ years and always swore by it recommending it to new kitten owners.
However over the last few bags it has definitely been changed. It longer clumps very well and does not cover the smell in fact it smells terribly. It’s with great reluctance I am changing over to another clumping cat litter
|
What have they done?
Been using this for years and never a problem until the last bag arrived. Doesn't clump anymore and you end up with a mess everywhere, this also increases waste of unused litter to just get the broken clumps outs.
If its not broken don't fix it!
|
Oko no more
This has changed. The latest lot seems two toned, and nothing like the last lot. I have severe wastage, it doesn't "clump" into snowballs like previously. It just separates and means I waste a lot. No way does it last as long. I've already had to top up under a week due to wastage. I don't feel the cat likes to use it anymore and will have to seek out another brand now.

Does not clump.
This looks and acts exactly as cheap wooden pellets purchased in B&M for less than a third of the price.
Feel I’ve been mis-sold. Certainly won’t be buying this again. Does not clump, just goes into sawdust Which you can’t seperate from the pellets. Wasteful.

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!!!!!
