Cat litter

Really good, easy to clean it

Something has changed! - no longer clumps?!

Used this product for years and loved it but had clumpubg issues with the most recent batch

What has changed? Change it back please

I have used this cat litter for years, I didn't mind the high price because it was worth it. There was No mess, no smell. now it sticks to my cats paws and goes everywhere. the clumps break up easier when cleaning, meaning you need to do a full litter clean more often. something has changed. I am now on the hunt for new litter. Change it back please as this used to be the best cat litter for multi cat house unfortunately it's not anymore

Something has definitely changed, and it's not for the better.

I have tried several 'good' brands of litter for my 4 cats, but always come back to this one. It used to be excellent, so didn't mind the price of it, but for the past few months I've noticed it's a lower grade of product. They've changed the formula, and now it's just a standard litter as the cheaper ones. I continue to use it because I like how easy it is to sift, but it's definitely reduced in quality. It's very disappointing.

What changed?

First bag i purchased was great, probably the best litter I had purchased. I then bought a large bag but something has changed with the litter. It gets attached to my cats paws, legs, body..... so I find it on the staircase, all over the beds, on the sofas. I am constantly hoovering to get rid of it. Must be horrendous for multicat households. Such a shame as this was a really good cat litter as other people have also mentioned. I would not purchase again.

Very good value and efficiency

I`m using it for the last 2 years, best buy ever. One 40l bag for 1 cat , used it for 7 months. Change it at 2 - 3 weeks .

Had cats for over 40 years and wish I'd also had this litter!

Recently rescued a Mum and 3 kittens. Was sick of the smell of ammonia and the dust from catsan, so gave this a try in one tray. It's amazing. Their wees just create a small ball that you fish out and there is no smell. We filled the trays quite deeply - maybe that's where the people complaining went wrong. I can't wait until we can swap all the trays to this stuff and I wish I'd known about it sooner. We struggled for years with the smell from our previous elderly cats.

Absolutely terrible

This stuff heavily resembles porridge oats. It as heavy as porridge oats. It will be All. Over. Your. House by day 2. Everywhere. The amount my cats can smuggle in their adorable hairy paws is frightening. If they were on an international flight I’d worry they would be stopped for concealing goods. It also does not clump. Instead, every wee fuses to the base of the litter tray like 4 day old Weetabix and requires an angle grinder to remove. I wanted litter not breakfast cereal.

worth every penny

great

My cats love this

I have 9 cats and they love this!!

review of cat & best

nice eating boolls and beens for pets

Easy to Flush!

I live in a second floor flat so having a litter that can be flushed is great. This seems to capture urine odours really well and while it does track a bit, I have never met a cat litter that doesn't!

Good cat Itter

My kitten uses the litter properly, when she first came to me she made a big mess in front of the litter box.

This is expensive and bad quality

It makes an absolute mess…it becomes a soggy mess and it sticks to all all sort of stuff and I am finding it everywhere in the house. I won’t buy again

Excellent

Good

Not as good as it was

A couple of years ago this litter was better than sliced bread. It clumped really well, and still does, but it ends up tracked all over the house, the sofa, the bed… My husband, who is the chief scooper commented that maybe I’d ordered the wrong one, as it seemed to not be as good, but I checked and it was the same. Perhaps the formula has changed, but I’m currently researching alternative brands as with 4 cats, you can’t mess about.

worst ever litter

Does not clump, just turns into a soggy mess. Absolutely terrible cat litter.

Tracks everywhere, all over the house.

Pro's - it clumps nicely. Easy to remove. Con's - it tracks every where. All over the floor, the sofa's, the stairs ( cats dont go upstairs. It sticks to slippers and feet then goes all over the house. For this reason I will never buy or recommend this product. I am forever cleaning up, washing slippers. It's even in the cat's fur. It's a shame because I liked how natural it was.

It’s changed

Have been using this litter (since it was called Okoplus) over 10 years now. It is totally flushable and used to clump really well.. now it breaks up easily, has gotten more likely to track off paws when cats leave tray and kinda looks different. Please go back to the original formula before Worlds Best became the name. Used tone 5*… now… 3* at best.

Great litter

Great litter for the litter box. Strongly sparkles the best litter you can buy

Superb

I've tried almost every type of cat litter, and for me and my cats, this one is the best. It's expensive, but it lasts quite a while.

We are satisfied

It's true, this is our first pack, but we're happy with it. Our kitty used to do his business on paper towels, but he quickly took to this litter. It's good for keeping the litter box tidy every day and it does a great job masking odours.

The quality has gotten much worse

I used this for 7 years, but now I'm looking for an alternative. For the past year, the litter has been dustier, the clumps fall apart, and even a single one can break down in water into a sticky mess that's hard to remove and can clog the toilet. Now the cat litter is even causing respiratory problems, despite removing clumps immediately and cleaning regularly. Looks like someone decided to cut corners on quality and brought in ChatGPT to help with it.

Perfect

It's true that it's more expensive than other litters, but for me it's worth it. It's perfect. It doesn't smell bad. My cat loves it. The dust doesn't get up her nose, since it doesn't release any.

Unfortunately..

I have to agree with the rather negative and disappointing comments. Since my last purchase, I've also noticed that the quality has changed. I can confirm the increased dust, the quick smell, and the crumbling of the clumps.

Gotten much worse

We used this litter for about 15 years and were always very satisfied, especially with how well it controlled odours. We had a 3-year "cat break" and have now ordered the litter again. After just one week, you can clearly smell the litter box in the flat. I'm massively disappointed.

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…

We've been using it for years

We've been using this cat litter for years, and it's the best we've tried. It doesn't make a mess like others, does a good job absorbing odours, and you can flush it down the toilet.

Used to be better

The litter used to be really good, but now the pieces have become smaller and drier, which creates more dust. My cat has had to cough more often because of this. I wish it would go back to how it was before. Until then, I'll have to find something else :(

Truly the best cat litter!

Over the years, I’ve searched for the best cat litter. Without chemical pellets or added scents, because cats are very sensitive to smells and things that aren’t natural. This litter absorbs pee well (and forms a big clump), so it’s really easy to clean. It’s also easy to tidy up around the litter box since it doesn’t have tiny pellets. The smell isn’t bothersome either. I can recommend it to everyone!

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.

Cat's Best Original cat litter

The litter is really good for my senior cats, for me it's the cheapest and lightweight. I don't recommend flushing it down the toilet because it takes a lot of water to do so. We need to save water.

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.

Clumps well and dust-free

I buy this litter because it clumps well and, most importantly, doesn’t raise any dust. Just a heads up: it expands when it gets wet or when the cat pees, so your kitty might get a fright at first, but they get used to it after a while. I love that Zooplus has the 17l pack, it saves me a good bit. Tip: get yourself a scoop for coarse grains so you don’t waste so much litter.
