Customers find this cat litter superior to clay alternatives, with good absorbency and functionality, particularly with Cat Genie systems.

Customers disagree on the litter’s dust control, with some reporting minimal dust while others find it extremely hard on their cats.

Gel is superior to clay. Hands down.
Amazing litter!To put in perspective how badly I despise *clay* litter….I would rather wear pants made out of steak & walk through a lions den than to ever have clay litter again! The way even the bougie-est clay litter turns into freaking cement when cats pee on it. Nope. Not for me.But this gel litter? Fantastic. It cuts down on smell bc the gel absorbs the urine and then literally all you have to do is scoop the poop. Also, if you want less tracking, or if you have cats that dig an insane amount, get this particular one bc the “pearls” are bigger and track less than the other styles of gel.As for how much you need. A Little cat math for you, lol: So the product description states that you can have one bag for one cat for one month. Unless you have a cat with medical issues who urinates more frequently, I’d say that’s fairly accurate bc I have a friend who uses one litter box for 2 cats (one full bag of litter at a time) but replaces every 2 weeks. I personally have 2 litterboxes for 4 cats (one full bag per litter box) and also replace every 2 weeks.

Micro crystals, no clay super absorbent no odor cost efficient love this product so does my cat.
avid micro Crystal user. Kitty seems to really like this probiotic litter as always micro crystals never smell totally eliminating animal odor, which is so important to me last for a month with proper removal of waste product. It is non-sticky. Iām able to sift with fast ease my kitty. Chose micro crystals seriously she doesnāt like hard clumping and the micro crystals seem to really be soft on her pads. Itās extremely lightweight. My small area never ever smells like a kitty litter box. Thereās never any Dusty weird odors that irritate my allergies, Iām an avid promoter and swear Every cat should use micro crystals! A little bit pricier than usual for this particular product, but totally worth it for peace of mind and more affordable than competitors it absorbs everything I never even notice any moisture at all ever even after a month when I throw it away, it doesnāt stick to the pan or anything. Itās the cleanest product that thereās there is out there for kitty litter boxes.

Definitely helps with smell! Tracks a little.
This review is for the Blue bag- for some reason when I try to review the pink bag with small ball crystals, THIS comes back up! ?? Anyway, I’ve used this Ultra litter to layer on top of clumping litter to help control smells with 8 cats (we do have several boxes). It eventually does get mixed in as you scoop, but one half to whole bag of this in addition to clumping litter, depending on the size of the box, makes a HUGE difference in the reducing smells and makes the box of litter last SO much longer before changing the entire box. Also the reduction in dust is AMAZING!! We have too many cats and too many boxes to only use this litter, I’d go broke, but even just part of the box helps on the dust. My only slight negative is these crystals do track a bit out of the box, and we have two cats who seem to not use this box as much as the others (I use the Ultra Micro Crystals, pink bag also, see other review) so I don’t think they like the bigger crystals on their feet. It does seem to be absorbent, though I wasn’t sure at first. The crystals will start to yellow when they’re used up. You will need a wide slotted/hole scoop to get the poo out (and clumps in my case) and not lose the crystals that are still good. Overall definitely worth it, even though cost wise it’s more expensive per pound than the clumping litter we use. The pink bag does not track as much as the blue bag does.

Pooling at the bottom of the box
this litter does mask the smell very well which I really appreciate. However, I clean the box daily and this litter didnāt absorb very well at all. There were always pools of pee at the bottom of the box. And since it mixed with the silica it was more of a pee gel. Really gross and smell would sting my eyes when I cleaned it. Gag. However when you arenāt in the process of cleaning the box the smell was masked very very well. Also the probiotic version of this brand turns LIME green when your cat uses it. Which kind of gave me the ick personally.

Buyer beware!
This is the worst cat litter I have ever used for SO many reasons… I would rather go back the clay and I HATE clay litter. These crystals are ball shaped, they’re too big to go through a poop scoop and they roll around when you try to sweep them up which gets annoying VERY quickly. This litter sizzles when introduced to water (I flush my cat poo but silica is biodegradable). WHY does it sizzle? Is it carbonated? WHY? This is unnecessary and cannot be safe for animals. This litter does not last NEARLY as long as other crystal brands as it is not absorbent at all; my guess would be because it is not a fine ground crystal but HUGE ball shaped blue things that are annoying and serve no purpose whatsoever. To top it ALL off…. its EXPENSIVE! A 4 pound bag fills one box one time and lasts for 10 days if you’re lucky and love your cat. Who in their RIGHT MIND wants to spend $15 every 10 days on kitty litter??? I would give this NEGATIVE 27 stars if I could. Would not recommend one bit.

Innovative Crystals
The BEST cat litter on the market!!! No dust/no scooping/no smell….just change out every 2 weeks. This is the only kitty litter I will use…Crystals that are on another level of innovation.

I’ve been using clay litter and the dust bothered my asthma plus I have an American Bully who was wheezing and rasping from the dust so decided to try this product. Noticed a huge difference immediately in my and my dog’s breathing. There is no odor at all which shocked me and so easy to clean. Btw- I am not paid or receive free products for my review and am genuinely happy I tried this product. I admit it costs so much more than clay litter but think about what the dust from the clay litter is doing to your cat and to you. If you love your cat…..at least try this product once and you seriously will not regret it. I have 2 cats and had to dump the litter box of clay litter almost everyday and the smell of ammonia was terrible. I only change this litter about every 2 weeks as the beads soak up the urine and I scoop the poop almost immediately. I buy alot from Amazon and this is the one thing I highly recommend.

It does stop the odor but thatās where the good part ends. The little is so large, it renders my sifting cat litter box useless. My carpet is littered with big blue crystals. This is one purchase I regret.

This litter is the best of all the types offered by this brand. Iāve tried the smaller granule clumping ones and the just made big gross gooey clumps that were nasty to clean. This one leaves no scent. Itās easy to clean. Relatively no tracking. I scoop frequently and fully change the box mid month and it all works perfectly! I also use a litter box with a guard on it and highly recommend it! My guy is happy š

I have recently started searching for a new litter for my cat as she has just this year started urinating A LOT. She’s 14 years old so I suspect it’s her age. I was using any variety of Arm & Hammer clumping clay litter for the last 14 years and was relatively satisfied with it. As mentioned, this past year my cat started urinating much more, and I was noticing pools of urine in the box every 3 days or so, which lead me to begin my search. I started with Dr. Elsies clumping litter. This litter clumped famously, however I was met with massive heavy chunks of clay each time I scooped. After breaking a litter scoop, I thought I would try crystal litter. I began with PrettyLitter, to see if my cat was sick. She’s fine, but that litter only lasted 2 weeks and it was saturated. This litter was my second try at crystal litter. I was hopeful, however, it’s been 10 days and the litter is too far gone. I was even realistic about the situation and used 2 bags in the box, knowing my cat goes a lot. I sifted it twice a day every day, and scooped the poops as instructed, however after day 7 I realized it wasn’t going to make it. I immediately ordered another brand. It took a few days to arrive, and I definitely should have replaced this litter 2 days ago, but today, day 10, was when I got the new bag. Please note the pictures, with about 1/4 inch of urine in the bottom of the box. This was 2 bags! So, I’m less than satisfied. Note my cat is 14, goes a lot, and I keep the box in the basement (which may be affecting the absorbency due to humidity, however, I do have central air and a humidifier on the unit). Anyway… my search continues. If you have a small young cat who goes a regular amount, this litter might be for you. If however you have an old cat or a large cat, I suggest 2 bags of this litter will last you a week.

I like it so m7ch better then clay/sand litter. Keeps the smell away so much better! There is some trackinh right outside the litter box, but its quick and easy to coean up. A lot less tracking then clay litter. I had tried a different brand, but my cats paws looked dry and irritated, this one has smooth crystals which is much more gentle on her paws. Took my cat a few days to get used to the change and she doesn’t bury her poop anymore, which is ok woth me because i clean it up right away anyways. Live the subscription too, reminds me of when i need to change it.
