Rated 5 out of 5 by from Amazing! I never thought I would get my kitty to switch litter but she went right to this. Dust Free!!!!! What a difference.

Rated 5 out of 5 by from Finally Easy Scoopin' We have 8 cats and found every other clumping litter would unclump and fall back into the box while scooping. With this, I just scoop and it all comes up in big lumps and stays together until tossing it into plastic bag. No dust which is safer for all kitties. We haven't tried flushing it yet but if we could without it clogging the pipes, it would save us on our garbage bill!! Much easier and cleaner and it does last with all 8 cats using 3 big boxes a good 20 days or more.

Rated 5 out of 5 by from Absolute The World's Best Indeed The only cat litter I use...totally heavy garbage bags to carry to the curb anymore!!! Worth the cost!! Too bad Wal-Mart Canada has stopped carrying this fantastic litter. The thing I miss about the little is the Lavender scented...No longer available here in Peterborough or Campbellford, Ontario, Canada. My cats seem to love this litter too.

Rated 5 out of 5 by from All around -- I just love it!!! I initially tried this because it was just corn. (I liked that!) Then I was elated to find --- YES, it does clump, there's no lingering odor, and though I don't know what's involved in the process, if there are chemicals at all they've got to be fewer than in those made from -- who knows what; so I'm especially thrilled that I not only don't have to breath any dust, but especially the chemicals in that dust. I dispose of the 'poop' in the toilet and the urine soaked corn I fertilize my flower beds with. (And they seem to like it!) I am truly grateful for this product, for the fact that it works in all the ways that it claims to, and especially for it "naturalness."

Rated 5 out of 5 by from Excellent Litter We were encouraged to use this product. We are so grateful to have found this great product. My first thought, was that it did not take as much product to do a far better job of clumping. Then, I realized how long it lasted. Lastly that it does not produce dust. I will never use another litter.

Rated 5 out of 5 by from IT REALLY IS THE BEST! We live in an apartment and have been using World's Best Cat Litter for years. Good odour control and no dust tracking on our hardwood floors. Although on the pricey side, it goes further in the long run. I highly recommend.

Rated 5 out of 5 by from Good product, less smell, less dust. I bought this a few weeks ago for our asthmatic cat and it lessens the dust and smell you get from other cat litters. It costs more, but it is worth it to get the best.

Rated 5 out of 5 by from Where, where, where have you been all my life? I have three very productive cats, and swear by this litter. I am on my 2nd 28# bag in 6 weeks, and am here to tell you that this is by FAR the best product out there to keep our kitties clean, and our homes from smelling like a litter box. No fuss, no muss. $$$ saved too! I use two jumbo open litter boxes in a large bathroom. I fill the boxes 4 inches deep, scoop, and add more litter as needed-about another inch or so every week. I scoop them 3 x a day, in the morning, after work, and at bedtime. The boxes sit next to each other atop of a good litter 'mat' and there is not much tracking. I do give the area a quick vacuum every morning for the few straggler granules, but it is nothing compared to clay litters. Note: I did try out Yesterday's News and thought I had found my solution - UNTIL this litter was suggested to me by my daughter who researched all types of litters and their internet ratings. She was right, and I am a forever fan! The clumps are entirely flushable. If you prefer to scoop and put in the trash, get yourself a Litter Genie and a long handled stainless steel scooper and you will be good to go. No odor at all when you use a Litter Genie. Otherwise, scoop, flush and you are set. For the first time ever, I get a strange satisfaction from scooping. The clumps are solid, do not fall apart, and absolutely nothing sticks to the sides of the litter box, so no more changing out bags, dumping tons of nasty litter and choking on stinky scented wafting clay dust that goes everywhere. Guests tell me they can not detect a litterbox smell, and as we all know, keeping the boxes scooped is the key. This is time well spent, believe me. Am I happy? Yes! Are Teddy, Bella and Snickers happy? Yes! When Mamma is happy, everybody is happy. Buy this litter, it lasts, is natural, not a granule is wasted, and my cats come back from their potty visits without smelling like a litter box and nothing stuck between their fluffy toes..

Rated 5 out of 5 by from Really is the World's Best Cat Litter I have used almost every brand of litter on the market and this is by far the best. Clumping ability is superb, minimal dust, and it covers up odor. I have had people say they can smell a litter box when they walk into a house but would never have thought I had one.

Rated 5 out of 5 by from Truly the World's Best I am so very happy with this litter, my cats love it, (well they use it) and there is no litter dust for me to cough over. It lasts well and I can't envision using any other litter. Well worth the investment, as it really costs less in the fact that it doesn't require daily changing and stays clean and fresh with daily scooping. I love the fact that its organic although I've never tried flushing it down the toilet, since I have 4 cats and use the multi-cat litter. A real KEEPER.

Rated 5 out of 5 by from Best I love this cat litter and so do my cats. It smells nice, has a nice texture, is not dusty at all nor messy. Somehow it lasts longer too so all around, we are all a happy family here.

Rated 5 out of 5 by from greatproduct I have been using this litter for years. I have recommended it to so many people. I have two cats and my home never smells from the litter box. It is also so easy to clean up. It is a little pricey but I wait until it is on sale and I stock pile it. You will not be disappointed it you buy this product. I have two male cats and I never worry about dust with this litter.

Rated 5 out of 5 by from We really like it! I like the pure, natural smell and the fact that we don' have dust that gets everywhere from traditional clay litters. It does the job beautifully.

Rated 5 out of 5 by from all time favorite litter! Been using this exclusively for about 4 years after trying many other kinds. Great odor control - and we can recycle used litter by dumping outside under the trees and bushes and letting it decompose.

Rated 5 out of 5 by from None other like World's Best! I have used World's Best for 5 years or so. I bought it to see if it really would flush, and it does! Plus No smell, my cats love it, they use it on regular bases. Really easy clean up and it last about 3 to 4 weeks until I change it. I have two cats. Also, if my cats carry a pebble or two out of the box when they finish, it is an easy vacuum to clean it up. You should try it and I am sure you will buy it!

Rated 5 out of 5 by from Great Product! This is a wonderful product. My cat's litterbox in, of necessity, in my home office/workshop. Other brands gave me a serious problem with dust from the litter which was not good for the several sensitive electronic instruments I use, as well as my computers. World's Best solved my problem! The clumping is a real convenience and it works far better than I have found with other products. An additional plus is the odor control. I am delighted to have found this product.

Rated 5 out of 5 by from Truly The World's Best! This is truly the best product in its class. Our three cats love it, and visitors don't realize that we have cats until they actually see them.

Rated 5 out of 5 by from No Dust!!! I love this litter! I can scoop the box without a big dust cloud in my face. There is an initial small of "hay" but it has gone away. I will definitely be using this forever!

Rated 5 out of 5 by from Great for small apartments! I bought this litter after being recommended dozens of it times, and it's only been a few days but so far I am loving this litter! I have a very sensitive sense of smell, so I was worried that by getting a cat, my apartment would always smell like kitty litter, but World's Best doesn't have that cloying, lingering smell that a lot of other litters seem to have. It does a good job at remaining scentless after the cat uses it too (give or take a few minutes, cat poop is always going to smell when it first happens anyway). Plus, there's minimum tracking, and practically no dust when I first poured it in the litterbox. I also love that this litter is flushable. I'm not going to make a habit out of it, but it's nice to know that I can guiltlessly flush my cat's poop down the toilet when she has a late night potty break and I don't want to go down to the garbage room in my building. It is pricier than other litters on the market, but honestly it's well worth the price.

Rated 5 out of 5 by from Healthy Cat World's best does not have artificial coloring, or scents,clay, silica dust, additives, etc...and can be flushed without clogging pipes. AND this litter also does not clog cat's organs when they inhale or ingest it when grooming Best for Kitty and Human.

Rated 5 out of 5 by from Good for the cats, no odor, lasts long & flushable We have been using it for nine years for our two cats. The price could be a little cheaper.

Rated 5 out of 5 by from Truly the best! I used it for a month now and the difference is day and night. The smell is noticeable only for the first 10 minutes after the cat defecates, but no scent in general. Very easy to clean and lasts much longer. Higher price pays off, no doubt.

Rated 5 out of 5 by from great litter and no dust I started using this litter after trying just about every other litter on the market. I love it and my cats seem to also. I just wish it was a little less expensive or that coupons were made more readily available.

Rated 5 out of 5 by from World's Best Cat Litter I love this - not sure about my cats, but it is easier to clean up especially the wet stuff. The scent is good also and no dust. I like the way it clumps and does not stick to the litter box. My cats will get used to it.
