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

This is the best litter ever no smell at all plus louie loves it.it last ages too much better than all the others

I hope they don't increase the price or I can't afford it, but this is the best, clamps perfectly, no smells and when you need to change the litter you can reuse the leftover as it stays perfectly clean

Our house is one with multiple cats, we needed a litter that could cope, didn’t get tracked by fluffy paws & preferably could be disposed of down the loo. After trying a couple of brands we’ve settled on this one, as it does everything we’d hoped it would. We even had an unexpected bonus, it lasts for ages. We’re not even halfway through the bag yet and the longevity has outstripped the previous one we used to buy. Very cost effective and efficient.

I've been using this for years - with four cats I need something fairly heavy-duty or I'm forever having to change my litter. This works very well for me.

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.

We have two indoor cats and we have used The Worlds Best since we got them. It is so economical to use and it flushes down the loo ! We use the extra strength and it copes tremendously well with two cats using one litter tray. No horrible smells and no trips outside to the bin in the rain. Never had a problem with it ( or our drains!) in 5 years. We recommended it to friends in Italy who live in a third floor apartment and they love it too! Brilliant !

We have 16 cats, all living happily in the house. So we needed to find a suitable litter. About 15 years ago we came across Worlds best, We took the advertising that it would save us money, reduce the smells from the trays etc... Well Oh My God, it doesn't just live up to all the reviews, but it exceeds them. We will Never change to another brand

Thank God for this litter really saving my back, very little waist, long lasting, very good odour control, in the long run works out cheaper, for example far less black bags used for disposal, less cleaning saves time and cleaning product's such as wipes and disinfectant. Much cheaper to buy from Zooplus, only negative one bag of litter was ripped and I had to tape it up. My two cats started using this litter with no problem.

Dust everywhere!

Have had cats all my life, but for the first time I have two INDOOR ONLY kittens - Siamese. I decided to go the whole hog and bought a posh covered litter tray, and plenty of this litter. Couldn't have been better. The litter absorbs the odours quickly, the clumps are easy to remove, and the cats are happy with it. No tracking problems. All in all a very good product. I use the lavender scented one. The Siamese seem to like it!

I have four cats two adults two kittens. Omg first trip to the litter box poo and pee. Pee instantly clumped. Very happy so far!!!!! Was using catsan before and washing emptying little box 3 times a week. Watch this space

Omg love this tried so many 4 cat household

I've used World's Best - plain, x strength & lavender 8 years, with numerous old rescue cats; all were fine. Flushing - clean, easy, safe; plumber said he'd never seen a cleaner soil stack. I scoop trays min 2x daily, liquids clump fast no whiff, easy to scoop. Slight dust scatter, nothing icky; less than any other I've tried. I use it deep in high sided trays and a bag lasts weeks. I deep clean trays weekly, but can always replace some old litter after cleaning trays, though v picky. Try it!

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

Much cleaner, great clumping quality and very economical. It took my two 8 year old British Shorthairs a few days to get used to the completely different texture of Worlds Best having used Cat's Best Gold for years but their ability to carry the kernels in Cat's Best up two flights of stairs was becoming more and more annoying. Very little escapes their trays now.

This litter really is the worlds best. I have 2 young house cats in a flat who love to pee A LOT and this is so much better than the catsan which I was using previously. So so easy to clean the clumps out and no smell what so ever. Slightly pricier than other brands but totally worth it for the fact the flat doesn't have a cat pee smell anymore! Lasts a long time aswell.

I've been using extra strength and lavender scented for several years, after trying a wide range of other biodegradable litters. Flushed little and often it does not block the plumbing (my plumber, replacing the loo last year, said he'd never seen such a clean soil stack). I found Regular does not mask smells as well (2-3 elderly rescues at any one time). Trays are so easy to clean, solids and liquids flushed three times a day, smells fairly well masked. Some scatter, but not too bad.

My best problem with this litter is dust. It crumbled into dust very quickly. I am still buying it as it is the best biodegradable litter I can find. It can certain improve.

This litter is amazing and even though you may think it's pricey it does last so really doesn't add up to much more! It smells good, feels good, doesn't leave much mess and most importantly my cats seem really happy using it. I've used this brand but not "extra strength" once before and I really noticed the difference as it didn't smell as good or work as good. The extra strength one is definitely the only one I'll use for my babies! :)
