This litter is super lightweight and easy to scoop. Perfect for hands that are sore with arthritis! It is dust free. It clumps urine hard and dries out fecal material (poop) so well that waste is minimal - even stays together in firm clump when my one cat pees along the litterbox wall and clump comes free from wall without extra effort. This is the best of any litter I have ever used in my 30 years of owning cars and working in kennels and vet hospitals!! Truly!

But there is a trade off. I wanted unscented (and used unscented scoopable clay litter too), and this litter is scent-free except for a subtle kind of woody smell when first poured into the box. The downside is that is does not absorb odors aa well so some days, I know when one of the cats has used the box because it smells. This is getting better as I find the best diet for my cats though (their poop has less smell so less smell to block). I have one covered and one uncovered litterbox and the smell is an issue with both equally I think. I am sure if I left it, the grass litter would dry the poop up great and the smell with it...but I can't stand to try it so I scoop right away when it happens, which is only occasionally. This is why I gave it 3 stars for scent. Not sure there is an answer to this without adding unnatural scents and/or dustiness to the litter - which are both worse in my opinion. Mixing some clay litter in is an option (see rest of review below) but I quit because of the negatives with this option. The clay litter just gets kind of sticky and is so heavy.

They track both of the litters just as much I think. The grass litter is much easier to sweep or vacuum up even if it gets into a wet spot on the floor before I get to it. The grass litter seems to get trapped by the mats I have the litterboxes on better than the clay litter did. I included photos of my most recent set up and it is the least amount of litter tracked beyond the mats yet!

My cats switched to this grass litter easily. I mixed in 1/4 or so of this new litter with their old litter. I had used Tidy Cat Clumping Unscented litter for years - all of my oldest 7 year old cat and for 12 years before that. As I scooped, I only added the new grass litter in as I needed more until the boxes were totally grass litter. On the 2nd litter box, I went from 1/2 or so straight to all grass litter with no issue (But be careful trying this - a picky cat might have balked and avoided the box because of this.) Two of my cats still prefer the Tidy Cat litter because they will use the litterbox with some of the Tidy Cat in it if I make it available (I had to experiment - pi ture 3 is a mix of litters) but all of the cats use the all grass litterbox some still even with Tidy Cat in their other box. Most importantly, they are perfectly willing to use the litterboxes fully and without issue with just grass litter in them both.

As for brand, I tried this brand, one other grass litter brand (Both chosen for first trial by cost and good reviews.) and a crushed walnut shell litter. The other grass litter was more dusty - not good for my cats or my allergies - and I think I may be allergic to walnuts. The walnut shell litter had a noticeable nutty smell (not bad, just noticeable) and minimal dust despite better odor control...but my eyes itched and watered and my skin started itching after changing and scooping the boxes. This stopped again once all the walnut litter was gone. So this grass litter is all I buy now.

I am going to order a couple of round, from the top litterboxes made by a start up company that are designed to work best with this kind of litter. Maybe the litterbox design will help with the occasional "stinky poop" issue. Just the lack of dust and ease of scooping due to superior clumping and lightweightness of the litter seal the deal for me. I am 6 months or so in to the switch and not planning to ever go back. I have 3 cats and two litterboxes. I try to scoop daily but have gone a week a couple of times and all of the above still held true. That was never the case with the scoopable clay litter. (Note: One litterbox per cat is the ideal but seems to be ok for us. I will post again if and when I get new litterboxes.)

Quick additional note - The two bags for my subscribe & save order arrived this time with holes in them! The outside box was fine so don't think it was a delivery issue. One bag's hole was a slice and had a red heavy sticker over it so damage clearly occurred pre-shipment. The sticker had come mostly unstuck though so litter was spilled out in the box. I am in contact with Amazon and expect they will make it right. This is the 1st time I had issues with a litter shipment. Not an issue with litter itself but I am honestly not sure if this brand of litter is available elsewhere, such as through Chewy or local pet stores, so if Amazon handling becomes a recurring issue and they are the only source, this could be a negative.)

We've had our cat for many years now and like most cat owners I've gone through several different brands of cat litter looking for the perfect (or realistically, the closest to perfect) cat litter on the market.
There is no cat litter that doesn't track! That's a fact. So in this sense this cat litter is the same. A good plush cat mat in front of the box helps a lot. But what is the game changer and most important to me is that it doesn't break down over time into a fine powder! And so fine powder never clings to the cat's paws creating little powder footprints everywhere. And most importantly, it doesn't create dust. AT ALL. There is absolutely no dust from this litter. I wanted to go through one bag first before I wrote a review. What I love most is that it never, over one month or so, threw up dust when I was vigorously sifting through the litter with my scoop causing me to hold my breath. And, when I finally took the litter box outside to dispose of the litter and pour it out into a compostable garbage bag there was not even a hint of dust! My last litter brand was a silicone litter, very good and absorbent and odorless but there was so much dust. When I'd pour it out I would have to step away. With this litter, nothing at all. And a natural cat litter I bought years ago was the same. It was great at first while the grains were new but in a short time it too broke down and became terribly dusty.
So, Smart Cat was quite a revelation.
There has been no odor and it clumps beautifully and I love that it's only made of grass.

I switched to this after using a walnut shell litter for a year because I started to notice that everything in my bedroom where the cat box was had walnut shell powder all over it - air filters, walls, counters, really anything I touched with my finger. This really freaked me out that my cats and I had been inhaling this for who knows how long, so I researched and bought this instead to try it out.

It is far, far less powdery/dusty than the previous litter or any clay litter that I have used. It's still compostable which is important to me because I'm trying to be earth-friendly where I can (I have separate compost piles for just the cat waste that I only put on my ornamental plants and not in the food garden). I also want to make sure that I'm using something healthy for my cats, and I'm feeling more confident about this product. I am monitoring for signs of dust build up, and so far so good. My only complaint is that it doesn't seem to work as well with the smell control for urine. I think that might be because my last brand had some kind of enzyme added to help with that specifically, as I don't think it's unique to walnut shells.

My cats readily changed to this litter, and we didn't really have to do the whole gradually switching it out thing, probably because this looked like litter they had used previously when I had them on a corn thing. You may want to do the gradual thing if your cats are not familiar with natural small crumble type litters.

In manufacturing, there is a desire for fast, high quality and cheap. You can only ever have 2 out of 3.

Cat litter is like that, too: Clumping, tracking, dust. You can never have all 3.

I gave this litter 5 stars because it gave me the 2 that I had to have: clumping, and no dust. And I don't mean "no dust" like the "99.9% dust free" that I see on litters that, when I stick my head in the pan to scoop, choke me, and make me wipe all surrounding surfaces to get that sticky non-dust off.

I mean, "no dust" as in:
- none in the air when I vigorously scoop (I get the faintest whiff of a grain-like scent, though, but it's a faint, natural, outdoor smell (this is UNSECNTED - yay!).
- so close to none on the surrounding surfaces
- even wiping the litter mat after a month had only a minor amount of dirt

Previously, I have used "Dr Elsey's" and the walnut litters (usually combined). Both are great litters, and do their job, and I would love to use them if the box was in the garage, but not in the house.
They clump well, track a bit, swear there is no dust, but my experience was dusty. Maybe my cat is a digger and a litter-shuffler (she is), and she will repeatedly go back and elaboratley mess around in the clean litter until someone cleans it.
If your cat goes in, does its stuff, covers discreetly and gets out, they are probably fine.

CAVEAT on the clumping: give it a few minutes. Try to scoop immediately and it is a sticky mess (but I think this is normal for all litters).

Other reasons I love it:
- UNSCENTED (healthier for me, healthier for my cats)
- good, very faint, natural smell
- unlikely to damage any hardwood floors (the litter consistency is more like flakes of uncooked cream-of-wheat than grits/sand)
- vacuums up easily (I can't tell you how annoying it is to have the stick vacuum just push granules of tracked clumping litter around in front of the vacuum head as you try to clean it (I'm looking at you, "Dr Elsey's")! Not with this...just gets sucked right up).
- no odor (okay, if my cat leaves a stinking bomb - nothing will work, not Poo-Pourri, Febreeze or a 14-year-old boy's dosage of Axe body spray, so I don't use that as a litter odor metric, ever...it's just got to go). But I stick my head into the top if the litter box enclosure and dig around, even after a month, no pee smell ever, no lingering poop smell (assuming none is waiting to be removed), smells fresh as the day I washed the box.
- no rock formations cemented to the sides: "Dr Elsey's" was prone to this, but this litter almost seems to protect the box. Scoop stuff up and it rarely leaves anything stuck on the box.
- less weird feeling on the hands: you know what I mean, that tacky/slimy feel on your fingers when you wash them after you get some the dust on them...guess because there is really virtually no dust.
- I use a jumbo litter box

and shield, and I pour one bag of litter in at the beginning of the month. Occasionally, I have to add a bit more at the end of week 3, but I am more generous because I have a digger.

Overall, I like this litter. It has a pleasant, natural scent -- it's not scented/perfumed but has its own smell that makes me think of wheat, but I'm not totally sure what it's reminding me of.

One or both of my cats exclusively pees in the front and back of the litter box, so those two spots have to contend with all the urine. What I've found is that SmartCat doesn't clump quite as well with this volume of pee compared to the clay litter I most often use, Precious Cat. However, this also means that it's easier to get litter off the sides of the box when scooping.

As for odor control, it's comparable to Precious Cat but I think Precious Cat might have a little bit of an edge here because it clumps a lot more and probably contains the odor a bit more as a result.

Dust-wise, I haven't noticed much of a dust cloud when pouring it.

Lastly, the main con: the tracking. This litter is lightweight and will be kicked and tracked WELL outside the box, unless you have a covered box. I do not as one of my cats refuses to use covered boxes, so my solution was basically making a litter pad landing strip and vacuuming more in the area.

I may switch back to Precious Cat but still like SmartCat and would use it over Precious Cat in some situations. If you have a cat or other pet that eats clay litter, SmartCat would be a great alternative and shouldn't be too difficult for cats to adjust to. My cats had no qualms about at all after years of being used to grittier clay litters, but YMMV, of course.
