How long does it last?
Answer by McgeeJun 24, 2022
I have been using this litter for 5 plus years and it is the best cat litter I have ever used hands down. The key is scoping it frequently at least every other day If you have 1 cat. There is no perfume smell no dust at all.I scoop in a gallon size non zip locked bag and throw in my kitchen garbage and you never smell anything. Love this litter!!!

How dangerous is it for a cat to ingest this litter (in comparison to clay litter)? My cat is currently licking her litter on occasion, and while I am working with her to stop this habit, I want to know what I'm working with. Thank you!
Answer by ChewyFeb 02, 2018
The Cat Litter is not recommended for consumption but is made of all natural grass which is better than clay being ingested.

Approximately how long does this litter last?
Answer by ChewyDec 22, 2018
The litter boxes should be scooped every day and about every 3 days add fresh litter to the 3-4 inches level. The litter should be changed completely only as needed.

Is there anything about the processing of this product that would assure that there would be no bugs in it? I sometimes read about natural litters having bugs. Thanks.
Answer by ChewyOct 24, 2019
Neither the mites nor the eggs would survive the manufacturing process for our natural litter; should some mites or eggs somehow manage to survive at the time of packaging, grain mites cannot survive with if the grain moisture drops below 13.4%, which means they would not survive inside the packaging.However, the litter could be a food source for the grain mites “if” the litter box is maintained in a hot, humid, and dark location. Storage of the litter box in a cool, dry, and lighted area would keep the grain mites out of the litter

Nearly purrrrfect!

I didn’t want to take off a star because honestly the 2 negatives are far outweighed by the positives! Everything claimed on the bag is 100% true. I was skeptical, especially after trying all different kinds of the “best” litters out there. I had to put their box (it’s big as the cats share - small house) in my bedroom after I’d moved… then just kept it in there because, like some litter voodoo, I couldn’t smell even the stinkiest of dumps (and oh, my little one makes deadly stink bombs). I thought it was gross to keep it in my room but WOW. No smell (even the fresh litter barely has a scent, just kind of “natural”), NO DUST, doesn’t make pee clumps stick to the box, clumps SO WELL, and the granules are finer than clay so it’s a lot softer on their paws and they seem to enjoy digging in it. No more “floor digging” outside the box. As a cat momma for most of my 38 years (maybe box emptying chores started around 7yrs), I can actually say (after 4 months of use; on my 2nd bag), this is the best litter I’ve ever used. And the fact that it’s completely natural is such a win. Two negatives: 1) Pricey, but worth it if you can swing it! It lasts a decent amount of time. 2) Does track. I put one of those litter catchers down (the kind where you can empty it back into the box like a litter-catching pocket), which helps, but I still keep a dustpan right there. But aside from pellet litter or other non-clay alternatives (which are just not appealing to cats), it doesn’t track more, and as it’s so soft you aren’t yelping OUCH stupid litter! if you step on it in your socks. I do have a wall around my box, not a hood, which probably helps with flinging, and might fashion some sort of platform they have to walk on to go in and out, that has litter-catching abilities. Unlike some other reviewers have said, it does not get stuck in my cat’s paws, and it clumps so fast and acts almost as a desiccant with the poops - they never have wet or poopy paws. So the tracking is pretty much isolated to maybe 2 feet around the box, AT MOST. I’ve definitely never written such a detailed review for cat litter but I know how much reviews can help people decide on what to go with. I’ve already shared it with all my fellow cat parents because it’s a smell-free, dust-free, fast clumping, organic game-changer!! Definitely not sponsored, wish I was LOL.

I tried real hard to love this cat litter!

Grass? Or grass seed? I'm still not sure which it is! It does clump and scoop well. As most do. BUT it gets on her feet and she walks it EVERYWHERE! And it gets wet when she pees, sticks to her feet and gets walked right to my bed! This cat litter is ruining my relationship with my 13 year old sweetheart. I cannot wait for the second bag to be gone! Too expensive to throw away too. Sorry, but I hate the stuff!

This is litter awesome

let’s get it out of the way first, it does the best clay litter(i’ve tried every litter imaginable!) even if it says it doesn’t, what’s great it sweeps right up, so easy, doesn’t make a mess like trekked clay litter does if it gets stepped on or wet or’s a dream. i didn’t believe it would clump well but man, it does! also, it doesn’t stink like pellets or perfumey clay litter, or have cat pee smell when saturated like clay, it doesn’t smell. also, it’s a breeze to scoop because it’s so light, no more fighting your way through to dislodge litter from the side of your box! honestly i’ll take the trekking for all the pluses! plus it’s more environmentally sound - biodegradable and renewable

Great litter with TINY drawbacks

Long review incoming. But worth the read if you’ve been desperate to replace your overly dusty clay litter without losing the other perks. Started using this litter about four months ago. I started out by mixing it with clay litter and recently have been using it 100% by itself now. Pros: - Virtually dust free. - Clumps like a dream. (No more scraping muddy residue off the sides and bottom of the boxes. This leaves literally nothing left over.) Incredibly impressed with how well this clumps and how easy it is to remove from the box. - Natural and environmental friendly. Easier on your kitty’s beans. Cons: - Yes. It tracks. BUT I would say it tracks just barely more than their clay litter. I spend about five minutes every day sweeping or using the hand vacuum to maintain the house. If you don’t do this, then obviously the tracking will get worse and worse as it piles up. - Occasionally there is a bit of a musty smell in the room that has the litter boxes. This litter doesn’t seem to conceal smells as well as clay litter - but it’s very faint and doesn’t happen all the time. Mind you, these litter trays are in the spare room closet with a built in box to conceal the litter trays with a small entrance. It prevents a lot of smells from escaping the area, so depending on your litter box set up, it’s really hard to say how it will smell in your house. (I am posting pictures for reference.) I sprinkle some baking soda into their litter trays occasionally, which helps. I scoop once a day but I’m assuming twice a day would eliminate any smell at all. - Not sure what one of my cats does when he’s in there, but every time he comes out of the box he has dust/powder on the side of his face. Almost looks like saw dust. But it’s always just on the side of his face. Not really a con. He’s a dork so who knows. I have been using Fresh Step unscented clumping clay litter for years and years. When they changed to “simply unscented” it seemed their formula changed with it. There was so much dust that it would cover everything in the room. We ended up building the box containers in the closet to prevent the dust from escaping into the room. We also added an air purifier into the room and left it on the low setting 24/7 to hopefully suck up a lot of the dust in the air. But I felt so bad about the cats breathing that dust in every time they went digging in there. I have searched and searched for a different litter for about a year now and I have finally found it. I will be using this one from now on. The SLIGHT increase in tracking is worth being able to switch to something more environmentally friendly and dust free. If you are unsure, I highly recommend mixing this litter with your current litter to see how you like it before committing to a second purchase.

We love this litter for the odor control, fast clumping, and no dust. It really has no dust! But the tracking is terrible. It sticks to their feet and they track it all over the house! There's so much litter on their feet when they get out of the box! We're having to vacuum at least twice a day, sometimes more! Oh, and another negative, because it's made of grass, our dog keeps eating it!!! UGH! I wish they'd improve on the tracking problem, because everything else, except our dog eating it problem, is great.

Best Cat Litter Ever

This is the best cat litter We have ever used. We moved out of state and could not find it here. We bought a store brand that smelled horrendous. Even our two cats did not like the cheaper litter. So when we realized Chewy sold it we had it delivered. It has no odor, no dust and it is the best litter our cats love. It does not cause allergies and our cats love it. It reduces my asthma. Thank you! We highly recommend spending a little more for the litter. It is worth it! :)

Great litter!

I really like this litter and, more important than my opinion, my cats like it too! It's lightweight, although the large bag that I bought is pretty heavy.... It does a great job!

Does not control odors

I've used this once before and it controlled odors well but the last batch I received does not control odor at all, specifically urine. It is 100% dust free, lightweight and clumps very well. My cat refused to use it once the urine odor set in even with clumps removed.

Works in the litter robot but bad smell & tracking

We have 3 cats and I was so excited to find an earth friendly litter than actually works in the litter robot (we have the newest model, the 4). This litter clumps well, but the ammonia smell is terrible and there is so much tracking. I really hope to one day find a biodegradable litter that actually works!

not quite heaven

This litter does well for odor control but it tracks more than another similar brand. I've found it helps to lessen the tracking by adding the litter made with walnut pellets. The pellets seem to make kitty open his paws when leaving the litter box. I don't plan to order this brand again because of the tracking.
