Good Alternative to clay/carbon litter

Good. Absorbs moisture well, but is quite a bit more expensive. Not really sure if it's worth it. It was worth it when this product listing was for two packages.

Better alternative to clay litters with ridiculous amount of harmful dust they produce. This product also produces dust but it doesn't seem to travel throughout the house like standard clay litter does. Be warned thought that the comments about the brown color staining the surrounding area seem to be on point. My pristinely clean litter box is now tainted brown all over the place from the settled dust and it does not wash off. Clumping seems to be a lot less tight even though lots of people say its superior to clay? I am still in my transitional stage so I am mixing clay and this product together which might be a factor?

Update 12/27/15: As much as I want to like this litter the dust it produces is just out of control. Brown powder everywhere. I live in a tri level apartment with the litter box mid level. There is brown dust on ever level. Also the clumping strength is below average at best. If I have to sift what so ever, the clumps break apart. This is with the urine sitting for a few hours so there is plenty of time for the clump to harden. I can't understand how anyone reviewing this product can say it's dust free?? Are we using the same stuff?? Oh well. The quest continues.

Both my cats made the switch without a hitch. It is NOT overly perfumed like another corn based litter we've used.  In fact, it only has a slight natural woody scent.  It clumps very well. There is very little to no dust and it lasts two weeks opposed to one week with other corn and clay based litters.  It is 2x more expensive here on Amazon than at my local grocery store.  It is only $8.99 per bag.

I ordered three so-called "dust free" litters, because I was SO tired of the clouds of noxious dust that have appeared in cat litters in recent years. I am convinced this has happened as a profit-enhancing scheme by the manufacturers. It's more profitable to NOT sift out the dust the way they always have, so they can sell dust-&-litter for the same price as clean litter. (I wonder what respiratory diseases, in both cats AND their owners, will result from this greedy practice?) This litter is dust-free, but it's not as good at clumping or odor-control as I wanted. Another one I ordered, the World's Best Cat Litter looked like hamster pellets and was almost impossible to sift, due to the size. The Dr Elsey's Ultra Precious cat litter was PERFECT, however. Excellent clumping and odor management, and NO DUST. I suggest you try it. As for the green footprint of various litters, consider the immense amount of fuel and materials needed to grow and harvest corn. It's might even more than for mining litter clays.

No dust at all. Does not clump like clay litter. I have had no problems with flushing this litter down the toilet. It breaks up a little too easily when trying to get rid of pee spots, so be prepared for that. I did not like the smell of the litter and neither did my kitten.

Break them into the litter. Start by replacing 1/4 of your current litter with this litter and steadily replace your litter with this litter every day. I replaced 1/4 of my litter every day with this litter. I made sure to keep some of the old litter on the top and slowly replace that light crust of older litter with the new one. Do not push your cat into using this litter right away! However, once your cat is into it, you have nothing to worry about.

A little too expensive, but a great middle point litter if you are teaching your cat to use the toilet. REMEMBER- get your cat on a flushable litter like this BEFORE you try any open hole - potty training methods.

Best litter out there in my oppinion. I have a cat who has always been allergic to clay litters and didn't like any of the natural ones I tried. This product doesn't irritate her allergies and it keeps the smell at bay longer than any other litter I've tried.

ADVICE:  When switching from clay based litter to a natural product be prepared to take it slow, introduce the new litter as a 50/50 blend with what your currently using, followed by 75/25 and finally 100% to allow your pet to adapt to the natural materials.  We wish we had know in advance as we nearly had a cat-astrophic mutiny of biblical proportion.

What a huge difference this makes, our attempt to describe the difference of clay based industrial products to this natural material litter wouldn't do it justice.  Our cat wasn't initially pleased with our decision without his prior consent, but didn't take long for him to accept the change.

After using cat litter that would cover the room with dust, then moving to the natural ceder, corn, pine products that were smelly and hard top scoop out of the box, I found this Generation Earth cat litter. I dumped the whole box in the cat box and I did not see a big dust cloud you normally see when you pour on litter. It clumps up great. all the liquid comes out. My cat would only pee once a day I noticed with the natural smelly cat litter I was using. Now she is relieving herself 2 -3 times a day now. There is no smell coming from the litter box now. Thank you Generation Earth.

Works well. One cat took to it right away, the other (older) cat does not seem interested in using it (fortunately, I have two litter boxes and have only changed one over to this litter). It is much lighter (per scoop) than the other light clay-based litter I use. It clumps well, and the clumps do not fall apart when scooping. The litter has a bit of a grassy/grainy/earthy odor; it isn't unpleasant (to me) but I wonder if that's what is putting off the older cat. This litter is actually dust-free!! -- a VERY pleasant change from the "100% dust free" clay-based litter from which plumes of dust are seen when pouring or sifting and which leaves a building film of dust all over the basement.

I love this litter. Much better than the clumping clay based litter. I am surprised at how well this controls the smell. In my experience with clay litter, scented ones are too pungent and gave me severe allergies (I originally thought I developed allergies to my cats) while unscented ones did a terrible job at controlling smell. This one is perfect, my cats adapted very well to it, it reduces tracking (when maintained since it is non clumping) and so far it has not caused any allergic reactions. Not going back to clay litter at all.

I was skeptical at first about switching to corn litter. I thought it wouldn't clump as well as the clay litter and that it wouldn't mask smells. Thankfully, I was wrong. This litter is so much better than the clay litters I was using and it lasts longer too. It clumps quickly and stays clumped so it's easy to scoop. Also, the clumps are smaller so litter isn't wasted which saves me money and offsets the cost of the litter. The odor control is comparable to the clay litter and has an organic smell instead of a harsh perfume. Plus, the corn based litter produces very little dust and the pieces that get tracked out of the box are easy to clean up and don't streak across the tile floor when wet. I can't find a negative thing to say about World's Best Litter. I love this product!

I haven't purchased through AmazonI started buying Litter One when it first came out on The Grommet, and now I've started subscribing no the Litter One website (where it's far cheaper; check it out). Have been using it for a couple years now and absolutely love it (evidently)!!

I have two male cats and they transitioned to it nicely. It is so much better than any of the other litter methods I tried. First I started with the big bins and the clay litter; so ugly, smelled, the clay dust drove me nuts, and overall it just really annoyed me. I then spent $100+ on&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/ModKat-Litter-Box-Black/dp/B0054IJX4W/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">ModKat Litter Box - Black</a>&nbsp;(yes, I'm embarrassed, but it would have been totally worth it if the Litter One didn't exist). the ModKat is at least stylish, helped with the smell and not getting dust everywhere, but still found it annoying, hated having to clean it all out, that they always scraped through the bags, etc. etc.

Litter One is truly fantastic in all ways and I cannot recommend it enough. I've also seen the improvements they've made over the years, which have all been well thought out and much appreciated. The one annoyance is that the little pellets do end up littering the outside a bit, but sweeping those up every now and then fixes it that. Also it sometimes seems like the fake bottom should be larger, because the holes get clogged up, but then I just scoop out some of the powdered-down kernels instead and it works fine.

I used to use Ever Clean cat litter and found that it worked well and my cat liked it well enough. However, a couple of years ago I switched to this Blue Buffalo product, partly because I wanted a more sustainable litter and partly because of the health risks of using clay/silica based litter. If you want more details on the health risks then click my name and youll see a review for Ever Clean, posted a few days ago. To transition to the new litter, I layered the two litters in the box and then increased the amount of the new product over time. My cat seems to like it just as well or better and I also prefer it to Ever Clean.

It actually clumps well  its a slightly looser clump than the cement-block you get from clay litter but it doesnt fall apart when you scoop and the remaining litter stays clean. Odor control is also just as good as my old product and it also doesnt track or generate dust like clay litter. Because its less dense than clay litter, a 14 lb bag is actually not far off the volume of a 25 lb box of clay litter.

Clay litter like Ever Clean is strip mined from the surface of the land (for example, in Wyoming, where it was first discovered). Strip mining has a history of being environmentally destructive  land was stripped and then abandoned  but these days regulations are better (in some regions) and the top soil is retained and spread back onto the land and planted with grass and trees when the miners move on. Even still, this practice is not as sustainable as making litter from plant material (like walnut shells) that can be grown every year.

In terms of environmental impact, its also important to consider what happens to it after use. Flushing clumping cat litter down the toilet is not a good idea, partly because it can clog pipes. So, there are two main options for disposal: landfill or composting. If you do send to landfill, it won't biodegrade very fast at all because itll be compacted and there won't be much oxygen. On top of that, if your used cat litter is wrapped in a plastic bag and sent to landfill then it has a long journey ahead before it gets back to nature. Using biodegradable bags or cardboard-based litter pans can help.

Composting is an option. Some cities will accept cat litter in compost (green waste) bins, but San Francisco doesnt  this is partly due to microbial contamination concerns. But you can use it at home if you have a garden or a lot of potted plants. Your old cat litter (minus the poop) could be mixed in with your garden compost, or even directly into the soil. Pregnant women, however, should minimize contact with cat litter due to the risk of toxoplasmosis. If adding old litter to your garden, and you are concerned about pathogens, it could be restricted to use on ornamental trees or flowers.

Overall, Id rate Blue Buffalo Naturally Fresh Clumping Litter cat litter 5/5 gold stars but bear in mind that Im ignoring the price on Amazon  Im assuming this will change. In terms of social and environmental impact, I think that being made from walnut shells its one of the better options, deserving 4/5 green stars. Its unfortunate that its packaged in plastic bags instead of a cardboard box. Blue Buffalo emphasize their campaigns for pet adoptions and cancer awareness but have almost no transparency on their company operations (social and environmental impact). Ill update this review when I find out more on these fronts.

I like the faint scent of walnut and the litter clumps well and absorbs odors, BUT my particular group of mau, Maine Coon, and half-Aby uses it as a litter pan of last resort.  They do use it, but it's not their first choice.  Their first choice, unfortunately, is clumping sand, which just is NOT environmentally sound.

LOVE This stuff! Almost no smell, unlike regular clay litter, and I like how it can be composted.

Better than the few other cat litters I've tried.  Still seems to track out more than I'd hoped, but at least the cat likes this better than fresh step and some wood stuff I tried.  Reasonable price.

I loved this box.  The clay litter they recommend sometimes sticks to the rakes but goes away on the next 'swish'.
The litter I started using was an all natural clumping/flushable called Worlds Best Cat Litter.  It's made out of corn.  It's a little dryer and doesn't stick to the rake as much.
But the litter pan is great and really keeps the smell down in the house while I'm at work.
