I have been using this litter with a Litter robot. It clumps enough that when the machine cycles it drops in the bin. If the litter isn't deep enough it can stick to the bottom a little but not found this much of a problem. I have 2 Ragdolls and they both have no issues using. Biggest issue is its very dusty and they come out with dust on their faces. If I could find a similar natural clumping without the dust...I would change it. Other than that its a great product and we have no smell issues.

This is the fourth type of litter I have tried for my sphynx kitten. It said 99.9% dust free, but when he comes out of the litter box he leaves dusty footprints and has dust around his chops and on his paws/legs... It is good quality though and feels like natural material. It doesn't get caught in his webbed feet as much as other types of litter I have tried!

Our last litter used to track everywhere and get stuck in between our long haired cats toes when wet so I splashed out on 4 sacks of this thinking it would solve that problem. I hate the idea of him having sore feet and then ingesting the clay litter when trying to clean himself so this seemed to be the perfect solution. Let me just say, I personally LOVE this litter but one of my 4 cats does not. He has started peeing next to the box and in the bathroom sink. Real shame because it’s fantastic

We decided to try this brand, as the litter we usually have does appear to be as effective as it once was. I had been sceptical as I thought fluffy under paws might track it all over the house. We mixed it with the last of our litter to get them use to it & so far so good. Tracking hasn’t really been a problem. It’s not impeccable there can be a smell at times, but for the money and the benefits we’re happy and would reorder this.

clumps very well, but not the best with smells. One of the worst.

Have tried lots of different litters and this one is the best, although not cheap. It clumps really well making clearing up very easy. I leave a deep amount in the litter tray and can remove soils without having to clean out the whole tray. It does make a bit of dust but not as bad as some others and it doesn't get walked everywhere like others do either.

I've used this litter for years, but recently it's become very dusty, and my beautiful black cat comes out of the litter box looking quite grey from the dust. I clean the litter twice a day, or more, but the dust is very annoying. It's an inferior product to what it was a few years ago. PLEASE GO BACK TO THE ORIGINAL FORMULA!

I wouldn't call this litter "dust-free" because, as good as the clumping is, the granules do break down into a powder as with most other litters, so I get dusty pawprints on my sofa. However, the clumping IS excellent, it's flushable, and there's relatively little granule tracking. I've tried Sanicat silica, Oko plus, supermarket clay, and this is definitely the best yet. I've got a big boy who makes enormous poos and a little girl who is very fussy about her tray and this seems to keep them both happy.

I have been using this since we got our ragdoll kitten and it is impressive stuff. It clumps beautifully and the fact you can wash it down the loo makes it so convenient. If it wasn't for the price I would not look for alternatives. So 5 for the product, 2 for the price. I would give it 4 over all and invite all to buy the Benek clumping biodegradable stuff as it is much cheaper and trails even less than World's Best.

Expensive - yes, it also does track a bit but we have 15 Ragdolls all of whom have no problem using it and it is substantially better than Everclean our previous litter which was dusty. It kills smells and the smell of it itself is not at all unpleasant. Overall it is longer lasting and cleaning the trays is almost a joy!

Although this litter is one of the best I have used, I am only giving it 4 stars. The positives are that it is organic, safe if eaten by the kittens or cats and can be flushed easily down the loo. It lasts ages too and clumps well. The negatives are the smell, it's kind of sickly sweet and it also doesn't absorb the bad smells made by our two siamese cats. Although I don't particularly have a problem with it tracking (I use a covered litter tray and have a mat there too), my daughter used it for her two cats and had real problems with tracking. It may be to do with how much the cats dig, I don't know, but when I stayed with her, I was constantly sweeping up litter even though she also had a mat outside the tray.

I normally use Worlds Best and thought I'd see if the Extra Strength was any better. It seems to clump better and doesn't track as much as the ordinary World's Best so was initially delighted - I didn't think litter could get any better than World's Best. Didn't notice much difference in the smell but one of my Bengals refused to use it as it was obviously very offensive to her so to save washing my bed linen AGAIN I'll have to throw out the rest of the bag. Really disappointed as I was prepared to make the switch to this even if more expensive as the benefits of less tracking outweigh the extra housework involved!! So I give 4 stars cos I loved the product, it's just a shame my fussiest feline didn't agree. :(
