Would give it 10 stars if I could.  I have several cats and litter boxes.  I have tried every litter over the years and this is by far the best.  Advance also makes 'light' in the purple box but that is not as good. The Advance triple action in the red box is the best litter ever, no dust, clumps firm, no tracking and all my cats love it as much as I do.  I hope I will always be able to find it here.

Won't get any other kind of litter after being introduced to this litter by my vet!  It does produce a dust while you initially pour it out, but the elimination of odor is unparalleled!  I have tried all the other products and none have ever even come close to comparing with Ever Clean.  Well worth the added cost, and especially worth it through Amazon Prime.

This is the best kitty litter system ever!  I have tried other automated systems, that broke within a few weeks, plus you had to deal with bags.  This system is totally hands off!  The litter replacement trays seem expensive, but they do last almost 2 months.  The crystals kill all the odor.  I had to put one in my bedroom as one of my older cats was starting to use my rug as a potty spot.  I have not had any poo smell lingering in my room, much to my delight.  My cats seem to like the box, at least they use them (I bought 2 of them).

Another well though out feature, is that each litter box comes with a lid.  When you change your box, you simply top the old box off with the lid from the new litter box.

I first tried this as a sample from the Blue Buffalo Rep at my vet clinic. It works SO WELL!

The odors are non-existent, there is minimal dust and only when you pour it in. My cats love it and safer than the clay-based litter for my gross dogs when they can maneuver the obstacle course to get to the cat boxes.

I will never use another litter. That's how much I love this product.

Fantastic litter. I have had one or two cats for decades, and this is by far the best for reducing odor. It is not a refillable litter, though - it is best to dump the entire box every month.

Best litter out there. I used to work at a naturopath retail pet store (sadly), and I've used all the naturopath garbage corn/walnut/pine/paper/green tea leaf litters and *NOTHING* beats this litter when it comes to clumping, odor control, and tracking. ALL litters are going to be dusty, but the only time that it's ever an issue is when you're dumping the entire bag all at once into the litter box (in which case, slow it down, and if your cat has severe respiratory issues). It's worth the price 100%. Love love love love this stuff.

You will be surprise how well this works..I clean the litter box 2-3 x a day cats are clean they like clean boxes to.. I love my babies and my babies love me.. walmart liter 40 lbs 13.49

This is the best litter I have ever used: great clumping and odor control, and it doesn't leave the litter pan messed up (i.e., not like litters that somehow become wed to the pan so you wind up having to clean them with soap and water a lot) so there is less cleaning of the pan itself, too.

Best thing to work for a litter box yet. I have tried every powder, spray.. you name it!!

I bought 4 of these and stuck them with some velcro double sided tape to the top of my cat's litter box, less than 24 hours and I already smell an improvement. Is it cleared it out completely... no, but hey it's a heck of an improvement.

On a side note,

best litter-premium litter-comes in big blue plastic bag. Clumps great, minimal breaking apart

BEST litter box- without a doubt!! the roll over litter box, I don't know the name but essentially you just roll the litter box to the side and the mess goes in a pull out tray!!

Great products!!

This is the best litter box I've ever owned. I've tried 4 different brands of regular litter, Breeze litter system (it's good but it grosses me out scooping uncovered poo) and this one. It does what it promises - saves you a lot of time with cleaning.

Pros:
- Saves you a LOT of time.
- No more scooping if you don't want to. Yay!
- Quiet, always clean.
- Lets you know your cats habits, since you can monitor use by checking the counter/resetting, so forth.
- No more litter on the floor (a few crystals, but because crystals are heavier than litter you don't see it scatter as much and it doesn't get as messy).

Cons:
- Not for kittens (and it says it in the box). My kitten got a little confused at first (and that was the only time ever we had "an accident" - he pooped just outside the box (ugh)). He was a little scared of the box at first, when he saw the rake moving and the "click noise" kind of scared him too (which is not loud and it gets quieter and quieter for some reason after a few uses - not because we got used to the noise, it actually smooths it out over time).  My other cat (an older kitten) was fine with it, although it took him a while to understand he's not supposed to try to cover the purple cover (he saw the poo going under the purple cover and he tried to cover that with the crystals).

- It may require you to spend some time watching them with this box while you're transitioning from regular litter over to crystals, to make sure they know what is for... well, isn't it always that way?
We actually didn't do that at first. We put the ScoopFree where the old box with regular litter was (and put the old litter box in a different place), and after seeing they weren't using it, we just removed the old box and prayed for the best... then a day or two later the small kitten pooped outside the box, so we started watching him around his time to poo, and when we saw him looking for a place to do his business, we placed him inside the box. Never had a problem again.

So after the adjustment phase, I LOVE this box. Both my cats use it and we've had no more accidents.
It is, however, expensive to keep buying the trays, unless you subscribe and save on Amazon (still not cheap, but cheaper than buying it separately every time).

Another thing about the trays is: it will NOT last as long as the manufacturer says it will - which makes it even more expensive to keep it. When the kittens were younger (6mo and 9mo) they pooped a lot and it would have to be scooped every couple of days (cause it's IMPOSSIBLE for me to afford to put in a new tray every other day). So I scooped it and it lasted a week. Now that they're older (9mo and 12 mo), the "volume" of poo decreased and it lasts about a week (for two cats). What I do is I dump the crystals and put in fresh ones from Fresh Step (which is actually better than the crystals that come with the tray, in my opinion). So basically, the tray lasts two weeks, the crystals last a week for me when I choose not to scoop so I can save time.
With regular litter, I had to scoop it twice a day when they were younger (yes, I told you they pooped A LOT!!) and don't know how it would be now cause I've never switched back :-)

It is hilarious watching them watch the box cleaning itself... when they hear it start (I usually don't hear it unless I'm around it... I only hear the "click" after it's done) they seat in front of the box and stick their necks inside it to watch it. It's freaking cute!! :-)
Hope this review helped! Good luck!

I have tried almost every brand of the litter, this one is the best of all, very strong and tight clumps .
Easy to clean .. AAA+

Best litter I've ever used, bar none! There is NO DUST, it clumps great and there is NO odor!! I use it in conjunction with the Natures Miracle disposable litter box and only have to do the litter box one time a week now...Highly recommend both together!

Repeat customer; very very little dust; very very slight tracking; clumps well; masks the odors well; and best of all IT'S UNSCENTED! I've noticed that some of the scented varieties (including this one) just don't mask odors well and usually end up creating a brand-new scent that's really kind of gross.

The litter is great stuff. I'd tried all kinds of different brands and nothing comes close to this. Last year one of my cats had a thyroid problem and was peeing buckets and this cat litter managed it very well. The clumps stayed clumped and were easily scooped up; I didn't have to pry-bar the clumps off the litter box; the rest of the litter didn't stink; odors were well-absorbed; very very little tracking.

This is best litter we have tried!  It doesn't bother my family's allergies and really traps odors even though we have 3 cats. The clumps hold together very tightly and makes cleaning the litter box quick and easy.  While I don't prefer scented litter, the scent is very light with Advance and not too perfumy so I don't mind it.  I didn't even realize it was scented when I first started using it until I noticed it was written on the next container I purchased.  I was glad Amazon had it because PetSmart stopped carrying it.  Pricing does fluctuate but it's still a great value.  This box is twice as big as the containers I was getting for ten bucks a piece at PetSmart.

When this is out of stock or the price has fluctuated too high, the Cat's Pride litter is the next best thing I've found as far as performance but the perfume scent is very strong.

This is definitely the best litter treatment I've ever tried, and over the years I've tried (what feels like) zillions of them. The key to success with litterbiotic is even distribution and very shallow mixing into the litter.  After I sprinkle the product evenly I poke gently around the entire surface with the scoop so that the litterbiotic granules are level with instead of resting on top of or under the litter surface.
Some of the negative reviews mention an ammonia odor -- in my experience an ammonia odor develops only when the box hasn't been scooped for a long time or if the litter isn't "scoopable."

After trying every litter under the sun and after recommendations from a forum board I subscribe to I decided to give this a try. While the litter is a bit dusty (which I don't mind) it does a superb job of clumping and containing the odor. It clumps so well that the urine doesn't even reach the bottom of the pan and it doesn't break apart when scooping it out. I've noticed I'm not wasting as much litter because of the great clumping job it does. Yes, it's a bit pricey, but I think I'll save money in the long run since it doesn't waste like all the other kinds do. My cat took right to the new litter and I am extremely pleased with this purchase.

2-28-12 Just received another order of this litter. I am thrilled that I switched to this litter. No more smelly litter and even my husband has commented that he doesn't smell the poop anymore. So, so happy!

I have used this litter for over a year now. I do not have cats but I use it for the litter in the cages for my parrots. It smells great, the clumping and absorbency cannot be beaten! Sifting the litter is effortless, its perfect for composting and its a bargain for the price. I have never been disappointed with this litter! Truly the best.
