Natural Cat Litter, Large-Grain Formula, Low Tracking, Exceptional Clumping & Odor Control, Virtually No Dust, Corn & Cassava Plant-Based, Unscented, 10 lbs

Finding a good litter is a constant battle for cat owners, but I think I am finally done searching. For our one-cat household, this has been the best litter we've found BY FAR. The clumping is phenomenal and is SO much better than any other litter my cat has ever used. This litter forms very hard, cohesive clumps that do not break apart, even with force, and are very easy to sift. No bits of clumps falling off or clumps breaking apart and getting mixed back in like with clay litter, so this litter stays clean. I find that it masks the smell well and there are no urine or feces odors near my cat's box (though it does have a very subtle wet corn smell while you're scooping that goes away once the clumps are removed). I have yet to see any dust coming out of the bag when I pour it in, which is a huge plus, as even most of the "dust-free" ones are not even close to being dust-free. I recommend scooping daily or every other day (well, you should anyway) because as more urine is added, the clumps become bigger and harder, and it might make it difficult for your cat to find loose litter to cover their waste until the clumps are removed. My only complaint, which doesn't change my rating, is that it doesn't last as long as other ones and is a bit pricey per bag. I think the fact that it runs out quickly is due to how well it clumps, but I find that it needs to be changed after about 3 weeks. As a funny side note, my cat has made some interesting "sculptures" with this litter. Maybe it's just me/my sense of humor, but some of the formations I have scooped out have actually made me laugh out loud. I attached pictures of some of the funny ones, like the dinosaur and the sad person looking down.

This is the only litter that works for my two giant, long-haired Maine Coon boys. However, I recommend the Large Grain, not Mixed or Small, for long-haired cats, and Small Grain for short-haired cats. I have been using cassava-based litter for almost 7 years, and back then it was out under the label "Garfield". -- TLDR All Grain Sizes: PRO - Fast clumping; Great odor control; Light color to track some health concerns; Long-lasting between changes; Non-toxic; Zero dust. Large Grain: PRO - Minimal tracking; No clumping/cementing in long fur. Small Grain: PRO - Fully coats stool for best odor control; Lasts longest between changes. CON - Poor tracking; Clumps/cements in long fur. Mixed Grain: CON - Most difficult to sift/keep clean (requires multiple tools / wastes more clean litter). -- Small grain gets cemented into long fur, and is nearly impossible for my cats to remove themselves and requires more meticulous grooming. Large grain is perfect for long-haired cat breeds because the granules are big enough that they don't get stuck in their fur at all, and can't even make their way in their toe beans, yet still amazing at clumping urine in the box. It's amazing. Tracking is so much less with large grain, and easier to clean up than the small grain. This is where large outperforms small grain for Maine Coons, hands down. The small grain gets tracked everywhere so easily, like the cats came from the beach and brought the sandy shore. However, if I had short-haired cats, I WOULD probably use small grain anyway. The small grain is actually my favorite in how it coats poop and how easy it is to keep the box clean because it's easy to finely sift out smaller pieces of stool (especially soft stool that got broken up, as one of my cats is sometimes overly enthusiastic in covering up evidence of his waste). Any grain size soaks up urine super fast, and I can scoop it out instantly for disposal, but waiting a little bit does help it to solidify. PRO TIP: Make sure there is enough depth of litter so that the urine can solidify quicker than it can reach the bottom. That way, there's less scraping and keeps the vessel cleaner longer. You'll figure out how tall you'll need to keep it filled/re-filled. It stays clean longer than other litters I've used, and it's easy to see when it needs to be changed. Small also stays cleaner longer because most mess (like tiny pieces of soft stool or urine) clumps larger than an individual grain, and with a good, fairly fine mesh sifter (PRO TIP: buy the ones sold for reptile cages for Small Grain!), you can really get all the waste out. This ends up making it a bit more economical. For this reason, I don't like Mixed Grain, as it makes scooping unnecessarily complex. You need a scooper with large enough openings so that clean, large grains don't get captured, but that leaves some dirty, small grains clumps too small to capture. If you use a finer scooper to grab those pieces, you're grabbing clean, large grains along with it. So PRO TIP: Skip Mixed Grain size to avoid difficulty sifting. Odor control is great, but I would say due to how the small grain fully coats stool, that it has a bit better odor control. Even so, people come to my house and can't smell litter box odors in the guest bathroom that has two very giant litter boxes that my two boy cats use the most. (We have a third, smaller one in our primary bathroom because 1.5 boxes per cat is the rule we go by.) The largest box they prefer almost exclusively for stool (sometimes urine), the medium for urine, and the third sometimes urine. PRO TIP: I've tried a lot of different litter-tracking mats, but found that for the large grain, Chenille bath rugs are the absolute best and easiest to keep clean. The tall, large pile essentially softly brushes most of the large grains off of paws, and allows me to shake them off back into the litter box. They then go straight into the wash on a regular basis. I keep a second set to replace the one in the wash. It's the best. I hated wiping or hand-cleaning other types of litter mats. Tracked small grains just kind of cemented (in fur, or on mats) and was always a nightmare to deal with.

Veterinarian and cat lover here. I have used a ton of litters over the years and unscented clay litter is what my cats prefer so that’s what I have always used. Based on other reviews I decided to give this a go. I have a litter robot, a regular pan litter box, a cat that makes super stinky poo and a cat that is asthmatic. I am going to review what’s important to me with regards to cat litter. *this is for the sustainably yours large grain only* 1. Clumping- this is by FAR the hardest clumping litter that exists. Period. Rock hard clumps. No crumbling. Super easy to scoop. It’s impressive. Nothing compares. 2. Scoopability: very easy to scoop and the clumps do not stick to the side of my robot or my litter pan. The thing I hate most about clay litter is the clumps always stick to the side of the litter boxes and they crumble making it hard to get it all out. With this litter the clumps stay in one piece. It would be very hard to break apart. Very easy to run my giant scooper through the litter and across the box. No digging like with clay and it doesn’t stick to the scooper. Box stays clean. Very little to no streaking in the litter robot globe. 3. Dust- zero dust. I have a cat with asthma so this is non negotiable. 4. Tracking - does track a little, not any worse than the low tracking clay litters. The litter is beige/yellow so if you have dark floors you will see it. I have a giant litter mat under each box and a chenille rug in the path and it contains 95% of the tracking. My Roborock gets the rest every day. 5. Smell: smell is very well contained in my litter robot but if my stinky pop cat poops in the regular box and doesn’t bury it, I can smell it. I refuse to use scented litters bc chemicals and my asthmatic cat, so the occasional stinky poo I can live with. 6. Cost: It’s expensive, really expensive. I guess you get what you pay for…If this is in your budget, it’s 100% worth it. I’m a convert and will continue to use this litter. I can’t speak for product consistency bc I haven’t used it very long. It did take my cats 2 weeks to start using the litter box with this litter regularly. My advice to introduce- add another new cheap deep pan litter box to what you have already, fill it with this litter only (2 bags = $40), put it in a cat desirable location, and give them a few weeks to adjust before you switch out their current toilets. If you decide to give it a go, I hope you like it as much as I do. Another reviewer recommended mixing with Boxie Pro and getting similar clumping results making it a little more cost effective. I may give that a try.

Very long and honest review. :-) Background: I have allergy-induced asthma and while some cats themselves bother me, I realized that it is actually the clay litter dust that I am more allergic to. My recently adopted cats also seemed to be having issues with every clay litter I tried (we went through 4 different 99.9% dust free options, and they were all still causing us issues in one way or another). So after tireless searching and reading reviews from multiple places, I landed on Sustainably Yours for my first try at natural litter. There are definitely some trade offs and learning curves when compared to clay litter that I am ok with, but some may find them to be deal breakers. CLUMPING/ODOR CONTROL FOR URINE 10/10: This BY FAR exceeds the clumping power of any clay litter for urine. I'm talking rock solid clumps virtually on contact. And it absorbs all the urine smell completely. CLUMPING/ODOR CONTROL FOR FECES 7/10: This is one area that requires a learning curve and a little more attention. My cats have chronic soft stools and this litter poses a challenge when scooping. Especially if I scoop it shortly after they go. If it is completely covered up, the smell is concealed vey well, but this litter only lightly coats the feces and doesn't form solid clumps like with the urine when scooping. So if you're using a large slotted scoop and your cats have soft stools, you will 1) want to leave the feces for at least a couple of hours, and 2) want to limit how much excess litter you try to shake out. If you scoop too soon or shake to vigorously (or virtually at all) you will end up with lots of small fecal particles left behind, ehixh is annoying. I did buy a second scoop with small holes to help with this, but it takes extra time to fish the particles out. I also use a Litter Genie and since the feces isn't heavily coated in litter, the smell leaks from the pale much more than it did with the clay litters. I have remedied this by putting a small amount of baking soda (like 1 tablespoon) in the pale each time after I scoop. Problem solved. OVERALL ODOR CONTROL 10/10: once I figured out the tricks above, it works great and there is no litter box smell in my house. I scoop their boxes twice a day, but I think someone could get by with less, as far as the smell goes. TRACKING 8/10: This rating is totally subjective and will completely depend on your current litter experience. I find that this tracks a good deal but not anymore than some of the leading brands of clay litter. We have the boxes in the basement and I find litter about 5 feet away from the box (with tracking mats), but not anywhere else in the house. I would find litter upstairs with some of the clay litters I tried, so for me this was an improvement. It is easily vacuumed up with the upright Dust Devil. DUST 9/10: Another subjective rating. This does have a small amount of dust (especially the longer it is in the box) but it is subjectively so much better than any clay litter I tried. Mainly because neither me nor my cats are allergic to these dust particles. With the boxes in the basement, the amount of dust is not an issue for me and is easily cleaned up with my normal cleaning routine. If I were using this in a smaller space, it might be an issue though. OVERALL RATING 8.5/10: The tracking and learning curve with loose stools drops the rating, but since we aren't allergic to this I am willing to accept these challenges.

I relocated to another town & my cat developed allergies. Immediately I began investigating pellets to use for his litter. I found Sustainably Yours. When I received the litter there were large dark brown flecks in it. This concerned me as it was not described online. I wasn't sure if it was an insect or was part of the makeup of the litter. I contacted the owner of Sustainably Yours & he sounded concerned & told me he would send me a replacement bag. I discussed the tracking problem & he told me that it should be pellets. He wants to send me the largest size pellet. I did not choose the larger pellet because online it indicated it tracks more than the smaller or medium pellets. The medium size pellets are what I purchased. After approximately one week I contacted the owner once again as I had not received the litter. I never received a reply. He disregarded me all together. When I initially spoke with him, he sounded concerned & proud of his product, but in all actuality had no intention of resolving the issue. That alone lets me know that he is aware his product is inferior. If the owner of the Company doesn't stand behind his product, I'm certainly not going to use it. I'm glad I never received the replacement bag because I would have used it, thinking the bags I originally received were just defective. The biggest problem is the tracking. What a nightmare! This litter isn't pellets, it's sand! The sand works it's way into all areas & continues to track long after the cleanup. I learned from the owner of Sustainably Yours that their litter is created from corn & what is used to make tapioca. The tapioca is what makes the litter harden immediately. As far as tracking..... tracking is the absolute worst I've ever witnessed! It's everywhere because it's finer than sand! It's a never ending struggle to get my home cleaned-up. Also, the more you clean the waste, the more It becomes a finer sand. I'm forced to vacuum 3 -4 times a day, sometimes more! Never have I encountered such a horribly difficult tracking issue! Once I started using this litter, dust began flying everywhere! I ran my fans for a couple of hours. The sand is going thru my A/C duct system as it's on my walls. It was a storm of litter dust that I could have done without! l now dust the walls as much as possible. What a horrible experience. My cat would only sit or sleep underneath blankets as he did when his allergies first began. He can see more dust in the air than I can. I have hardwood floors & know the litter is between the planks. I fear if I mop my floors the litter will harden & damage them! There's nothing I can do at this point. The more I walk on the floors the more litter presents itself. I have since chosen another pellet litter that is actually tofu & it's excellent! It's also a real pellet! The waste hardens & doesn't fall apart when cleaning up. The smell is non existent. The best is there isn't any tracking! I've picked up only 2 pellets in the past 4 days. Everything else about this tofu litter is right on as described. It's also 100% biodegradable so it's can be flushed! My cat loves it & his allergies have stopped once again. DO NOT Purchase Sustainably Yours! It will become your worst nightmare the same as it has become & remains mine! Tracking nightmare update, May 2nd, 2024: I'm still finding this litter when I vaccum! It has definitely lodged itself between my hardwood floor planks and each time I vaccum bits appear. I know it's not the current litter I'm using as the tofu litter I selected is green (there are other colors). Amazing litter! I strongly recommend if you have hardwood floors you contact an expert to ensure the hardening of this Sustainably Yours Litter wont cause any damage to your floors. It' was a mistake for me to trust this Company with a product they recommend to use inside my home. When initially advised of the issues they were kind and considerate. But the kindness and consideration ended with the conversation. They never followed through with the promise to refund or replace the damaged product I purchased. And they don't care about the tracking problem. I'm not the only customer that has mentioned the nightmate it creates. I believe the hardening could cause damage to my cats respirarory system from inhaling while using the litter. I sugguest wearing a face mask while cleaning or even pouring the litter out of the bag into the box. There is a dust storm that could possibly be harmful to any respiratory system. This litter is not delivered vaccum sealed as the current litter I'm using is. The new litter is thumbs up all the way around and I wouldn't have ever discoved it if I received the promised replacement or refund. I was played during my conversation and that's just unkind regardless how you perceive it. I rarely submit reviews but I'm passionate about this product for all the reasons mentioned.

An extraordinary product. Indoor cats have been part of my family for more than 65 years, as have the chores that help keep them happy and healthy. Sustainably Yours is a litter like no other—the best at nearly eliminating dust and tracking. And my cats, two bonded brothers Baster and Louie, have loved it from day one. I don't know how this works, but the litter freezes their waste solid with no smell. I mean liquid and solid waste scoop out like little chunks of concrete—no break-up, no remixing. And the litter doesn't weigh much. That means a lot to a 75 year old. If this review seems overly glowing, it's because Sustainably Yours is the finest litter I've ever come across.

No dust whatsoever, that's true... but it tracks as much as normal clay litter of the same grain size (the large grain still tracks like crazy). It's by far the quickest and strongest clumping tech I've seen but I don't think this is a good quality necessarily; unless money's no object. Big, sturdy clumps means big volumes of expensive litter removed on every sift. This is the most expensive litter I've tried, it's also the less efficient by volume. I filled my PetPivot automatic litterbox with a whole bag and within 2 weeks 70% of it has been consumed by one small 3.5 kg cat. This litter consumes at least twice as fast as the common clumping clay litter I used before. Yes, it's essentially odorless and there's no dust but the tradeoff is clear $$$. If you wanna keep your cat on this it'll be at least two fold more expensive than normal litter. Flushable, yes I checked!

EDIT: Fast forward. Several months of use now. I still favor this over the clay. I am noy sure what the people are doing who say one bag is gone in 2 days. I have 4 cats , 6 boxes and I have all stainless pans. They require more litter than a plastic box. I use 2-3 bags per each and because the litter left behind stays clean, I don't have to empty and clean the box every month to start over. I can scoop daily much easier (isn't a dreaded chore) and those claiming it is stuck to the pan are either waiting more than 4 days (the longest I have gone-the longer you wait, the harder it is to scoop but it still comes up) or they aren't making it deep enough so the urine has nothing to grab hold of. I can always take the scoop and just lightly work at the edge (think flipping a pancake or fried egg) and once you are under an edge, you can completely lift. It will stay in one piece and can be lifted without the entire pee-berg (like "iceberg") will stay togather. Definitely never going back to Dr. Elsey OR any clay for that matter. Definitely recommend buying a stainless steel cat box,too. GAME CHANGER! I have tried the mixed, large and small grains. My non picky ladies prefer the small and so do I. The "track" is like sand from the beach. The mixed and large grain seem to leave "crumbs" of the ladies' business in the box and require a fine mesh litter scoop to get it all out. This stuff isn't supposed to be changed but it will get a parmesan cheese odor after about 2 months so I change it out entirely and clean the box at that time. I purchased 3 stainless steel litter boxes to avoid the usual banging on the bottom of the box to get Dr. Elseys to turn loose. I was breaking sides of the boxes and replacing the plastic boxes every 3 months. I went to a blog that talked about making those stainless boxes successful for you and one of the things they stated was corn litter. One of the pages for this corn litter stated that it worked well with stainless so the switch was easy for me. My cats could care less, honestly. As long as the box stays in t he same place. I had to get rid of my litter robot because the Dr. Elsey's was sticking to the inside of the box and I was constantly having to dismantle and sanitize the plastic. I may go back now that I have this stuff. It clumps solid. No breaking apart. If it sticks to the bottom of the box,you can simply use the scoop to pick at the edge of the clump and it pulls away quickly, cleanly and easily. The stainless steel box and this litter are GAME changers. The stainless box never needs replacing and this stuff SUPPOSEDLY doesn't either. You simply add to it as there are no "crumbs" left behind. It does track a little worse than the Dr. Elsey's and seems to really work itself in between their pads because I find it downstairs when the boxes are all upstairs. The grains are so small though they are like sand, honestly so it isn't like you are finding piles of it or the huge pieces of clay. Never going back.
