I had been caring for cats for the last 22 years. Over that time, I've used a variety of different kinds of litter. So many of them say they will do something but this litter actually delivers on it's packaging promise.
My cat used the litter straight away, he didn't need to have his old litter mixed in with it. There was no smell of cat wee and it's easy to see where he went as the crystals he peed on turn yellow.
I would recommend mixing the litter about a bit to make sure urine doesn't pool at the bottom of the tray.

If I had to think of some constructive criticism for this product, I would say, the bag should be bigger and also, when the litter is fully saturated, that can appear quite sudden if you're cat is a big drinker.

Stinky cat litter tray, sodden clump of yuk at the bottom, know the story? I did.

This stuff is totally different, it just sucks up moisture and even dessicates (mummyfies LOL) cat poo into the bargain.

Basically the tray is dry, several weeks. I scoop out the solids and it looks pretty much as new.

As it ages it will go yellow or less opaque whiteish than when new, but it keeps on working.

When you do change it, the bottom of the tray is bone dry.

I only change it when it begins to smell a little, that is how I know its wearing out.

Otherwise no smells, no damp odours, its a miracle.

As I say I swear by this, I love it, the cats are much happier, used it now for several months and converted friends over to it too.

Just clean and disifect your tray before filling it with this, you can mix it with normal litter if your cats are fussy and need a slow changeover, but mine went to it like a duck to water.

And remember it lasts weeks, not days, thats a LOT of less bags of HEAVY wet litter to dispose of and even better, no carrying it home from the supermarket, Amazon delivers :-)

I bought this for my cat after reading the fantastic reviews about the lack of smell and the dry litter trays and how one small bag has lasted people up to 2 weeks; I thought this would revolutionise litter trays for ever!!
Unfortunately I have found this is not the case. I put the full bag in my cats litter tray 4 days ago and already it is sodden, bright yellow and leaving the bottom of the tray wet - it looks absolutely disgusting.
Yes, it did reduce the horrible urine smell and dry out the poo, so a big thumbs up for that, but it's now not fit for my cat to use and I've had to change the whole tray again, £4 in 4 days!
I've used catsan for years now and it's been brilliant, it's £10 for 20 litres which lasts me at least 4 changes and it does what it says on the packet.

Personally I will not be buying this product again due to the cost and the lack of dry litter - oh also it really really hurts when stood on!

On the plus side I phoned Amazon to complain and was given a refund immediately.

I would say if you cat isn't a big wee'er or will go elsewhere such as outside then this product may be perfect for you, but my cat is a litter tray only girl so was no good to her.
Purchase with caution!

This cat litter is very different from others I've used. It clumps really well and doesn't stick to paws, so doesn't end up on carpet outside litter tray. Highly recommended.

Having tried all known available cat litter products, in my humble opinion this is by far the best... In my own personal experience, I have been using this and only this cat litter for at least the last 4 years with 2 indoor cats... I use it in an enclosed litter tray with a cat flap entry and carbon fibre filters, I clean the the solid 'crap' out regularly yet find after about 7 or 8 days I have to change it because 8 to 9 days and it starts to smell and the bottom of the tray will be wet... This has been the case for as long as I've been using it so it's not just a bad bag or a bad week with my cats, but is time proven... Also, after 7 to 8 days and the vast majority of white crystals are now yellow having absorbed the urine... That said, prior to the 7 to 8 days there is absolutely no smell whatsoever and it is by far the easiest to clean and keep clean... Just a bit disappointing that, given I have 2 cats, it doesn't last half as long as it should and is quite a bit more expensive than others... ;)

These are nice crystals, they do last a good while if you have one cat, if like me you have three cats, its can work out expensive. It does cover smells of the urine type, however for number 2s it really is diabolical, especially if you have a kitten who thinks that the crystals are too horrible to cover up his business. Overall I would recommend it

I have been buying this for several months now after trying out all different types and brands of cat litter crystals and although this is not the best litter crystals I have had for my two cats, it does work out the best on price with the longevity coming second to a pricier brand. The other brand does last longer however at three times the price of this bag and for the same weight etc, this brand and bag works out better for us.

We have been using this with our PetSafe Scoopfree Ultra Litter Box and our Forever Litter Tray and it does work brilliantly alongside the two. What I will say is that I haven't yet found any crystals that last the claimed month that they all state and whilst this litter does fall slightly short of the premium brand we have used, it does work out that little bit cheaper. A 4.2l bag of the Bob Martin Litter Crystals lasts us around 7 to 8 days with our two cats before we have to change it and my husband does give the litter a stir every other day to mix the crystals around and make them last a little longer, whilst the premium brand was lasting us around 10 days before having to change it.

The litter crystals go yellow over time from your cat's wee but there is no smell at all until it needs changing which for us is around the 7 day mark. As our litter tray is hooded it doesn't bother us if the crystal colour is yellow and the only time any of it starts to bother us is when it needs changing and starts to smell however that is how we know it needs changing.
