I have a picky cat about litter texture (grain size). Is this similar in texture to a typical clay clumping litter?
Answer by ChewyAug 02, 2017
While the size is similar if not slightly more fine, the texture is a bit more angled. For an easier transition, keep your current litter box set up and start a 2nd box next to it with a mixture of the old litter and the crystals. The crystals will immediately help absorb odors. If you don't change the old box, your feline friends should naturally gravitate to the new cleaner system.

How is this litter with long haired cats? I typically buy crystal litter instead of clumping because otherwise it is caught in their hair. I know this doesn’t clump. Does it get stuck?
Answer by ChewyMay 23, 2019
This litter is made with sand-like silica gel crystals and offers superior moisture and odor-trapping qualities. It's super absorbent and will not adhere to your cat's long fur.

can this really last a month?!!
Answer by ChewyAug 07, 2019
This litter allows the water to evaporate so crystals can be reused up to a month for one cat for one month.

What color do the crystals turn after a cat has urinated?
Answer by ChewyFeb 15, 2018
When a cat urinates on the Ultra Pearls the crystals absorb the liquid waste and turn opaque with the absorbed liquid. Over the next several hours the water portion will evaporate into the air while the solids that are in urine (and cause odors) will be trapped inside the crystals. The clear crystals will start taking on a yellowish hue over the month as the crystals absorb more and more of the suspended solids from the liquid waste.

Really wanted this to work...

Read the reviews for all the crystal non clumping types being sold and chose this one because of the reviews. I just adopted a senior female cat who drinks and pees a lot more than my previous male cats (vet says she's ok, just likes to drink). Clumping clary litter was a soggy, muddy mess with her, where I basically had to chisel it out several times a day. The idea of this litter evaporating the urine instead sounded amazing. Except, it doesn't do that. At all. I rake it several times a day to encourage the moisture absorbing but it pools at the bottom of the box no matter what. We're on day 8 of an entire bag in a larger box, and it smells terrible. I can't imagine it lasting a month. I'm going to try some other brands to see if I can find the right one, because if it works, it will make a big difference. Pros: It' incredibly lightweight, and the crystals are very fine and soft so no rough textures that may bother a pet. Cons: Not very absorbent, stinky

Didn’t like at All

I ordered this because it was only thing I could get with supply chain issues for my auto cat boxes. It was cheaper, too. The crystals said micro… I am still trying to clean up from the chewy explosion that happened on delivery. Omg it was disaster… bags (and yes I mean multiple bagS) broke in shipping all over food etc. Nightmare to clean up. No odor control…WOW!!! Small pellets of poop in auto box, just all over nasty liter. Chewy was nice and replaced the bags, but horrible litter.

Overly scented

I really need unscented because I have breathing problems but this litter is very fine sand like and you can scoop out the pee if done immediately or mix up to dissolve. I ordinary use feline pine and it also absorbs the cat pee and does not clump at all. My cat has always used the pellets so I need to return to that litter.

So far, so good!

I was hesitant to try this litter, but I am glad I did. It is less messy than clay litter. I do keep both clay litter and this crystal litter as options, but I have been able to then cut down on the clay litter boxes. I thought maybe it would smell, but so far it doesn't. You just stir it up every day and scoop out the solid waste. I do have 5 cats, so it gets used more and therefore won't last as long (bag says 1 cat = 1 month), so since I have other litterbox options for them, I will change ~every 2 weeks. So far so good!

Cough, cough, cough

If you enjoy inhaling an ultra-fine dust that has cat pee in it, this is right up your alley. And if I don't want that in my lungs I'm not going to let it go into my cats lungs either. YES... it's light weight. YES... it's easy to get the solids out. But when it comes to looking for the solids you're mixing up the powder and I don't care for inhaling peed up powder. And it does get outside the box so when you are walking on it you're putting that in the air, too.

Good Litter

I’m a huge fan of this litter. My cats like it a lot. All litter has some dust and tracks to some extent, but this stuff beats clay litter hands down (I HATE clay litter). It doesn’t stick or get matted onto their paws like clay does, so they’re not ingesting litter when they groom and you won’t have litter on your furniture. Scoop the box daily and you won’t have an issue with odor. It has a fine texture and is soft on paws. Overall I can’t think of anything I don’t like about it.

the BEST !!!!!!

This is seriously the best and SO affordable. I’m a cat mommy on a budget and this works so well. I love how fine and tiny the crystals are because it’s soft on my kitties paws and absorbs so well.

fantastic litter

This comes in a blue bag and a pink back. I do not like the blue bag but the pink one is perfect. I have 3 cats and a large litter box. One of my cats is very particular. As soon as he smells urine he sits next to the box and won't use it. I don't smell anything but if I left it one more day I would. So I change it as soon as he lets me know! It lasts about 1 1/2 weeks.

Good litter - very dusty

I love the litter itself. I think it does a great job of absorbing urine and it doesn’t track as much as other gels. However it’s SUPER dusty. I’d like to use the litter again but I just can’t.
