No ammonia smell - no old pee smell - lasts a long time with multiple cats!
Size: 5 Pound
I'm new to crystal litter. I never knew the odor control that was available with it, BUT the ones in the store hurt kitty paws due to their shape and it's not long until it smells like a urinal since the pee is still in it. My cats act out when they start to smell it (ie spraying outside the box, etc.). This is the first time I've seen a clumping silica litter, so I was hopeful and definitely wasn't disappointed. The pee clumps easily and the silica absorbs ALL the ammonia smell, which I was skeptical since it's such a fine grain. Getting the urine soaked litter out in clumps prevents the urinal smell that normally happens so quickly with non-clumping silica litter. And the fine grain is soft on kitty paws and much less offensive if stepped on. It does scatter, but I'd prefer fine grain over the pearls that roll everywhere, or the lego-like larger crystals. I have 3 cats and in just two bags and ONE box (which I don't normally do, but did to test this out) it's still going strong with no smell, clumping well, and it's been 2 weeks. I LOVE this litter!!! I do have a kitty that scrapes away ALL the litter to pee so he generally just pees on no litter, but it still clumps when it's spread over the puddle of pee. Sometimes, if there's a fine layer of litter that he pees on, it can get to be very hard and crusted instead of clumping, but it doesn't give off smell still and it does come up in shards when scraped at well. If you have a non-stick box, I'm sure it helps with that, but I don't. Unsure why the price is so much higher for packs of 2 or 3, etc, so I just buy multiples of the single to get it at the lowest price. All in all VERY VERY happy and frustrated that I only found this now. Forever cat litter!

Holy Grail!
Size: 5 Pound
Though I am a new cat mom, I have spent the last three years trying to find the ideal cat litter for my needs. I have purchased the electronic cat litters with the crystal option kitty litter. I have been gone back to regular kitty litter boxes with clay. What I have learned overtime is that I have a low tolerance for tracking and for smell. With those two things in mind, I have tried many kitty litters. This one is nearly perfect…. Call me crazy but I feel that if I add a bit of ‘Fresh Step Advanced Clumping Cat Litter, Outstretch’ to this kitty litter - this recipe is Perfect. So essentially, I do a 16 oz bag and mix with a bag of these crystals. And voila. Perfection! Number one there is significant reduction in smell, which is a big issue for me. I have already had visitors. Tell me that the smell is significantly improved — if not completely absent. Then there is the clumping – there is perfect clumping with this combination. I just scoop with minimum fuss twice a day and I have a very clean kitty litter box. Also, I can go longer periods of time without cleaning the kitty litter box as opposed to my other options in the past. I believe I have been able to go 2 to 3 months without completely cleaning out the kitty litter and kitty litter box. Downside? There is a bit of tracking…. But I think this goes with the territory with having a cat. And I will take a little bit of tracking any day because this is really working out for me.

Decent product but the price increases are getting to be a lot
Size: 5 Pound
First off, I’ve been using this litter for a while and it’s the only kind we can use at this point. Both of my cats have bladder or stomach issues and the large crystals present in other brands would get stuck to them while using the litter box, creating some serious safety concerns. This type from ultrapets has smaller crystals and I haven’t had to clean litter obstructions on my cats, so very happy with that aspect. Though this litter is clumping, I have noticed that occasionally cat urine will cause litter in the bottom of the box to become more of a mushy/slushy consistency that will end up sticking to the box. In addition to daily scooping I have also found that agitating the litter helps the sticking. The main issue with the way it mushes and sticks is that I have to do deep cleans of the boxes with urine removal cleaner twice a month. Some batches are worse than others so the consistency is not always there. Some say a bag lasts a month but in my experience with 2 cats and 2 litter boxes is that we go through 3 bags a month. I like the crystal litter because in addition to trapping more odors than clay or pine, the litter itself also does not have a scent. All of that said, I am disappointed with the recent price hikes. At the beginning of September a bag was $14.99 and two months later the price is $16.98 a bag. I get that prices rise over time but $2 in two months is a lot. My household is stuck with this litter for a while but I completely understand how others would have a hard time justifying $51/month on crystal litter versus $20/month for clay litter.

I wouldn’t necessarily say it very well
Size: 5 Pound
This wasn’t my favorite. I do have more than one cat and I like the clumping litter. I wouldn’t say this clumps very well. I think I had to replace within a couple of days. It got a little mushy. But the cats didn’t mind it when we weren’t phased by me switching their litter.

QuickCrete for your cats
Size: 5 Pound
This litter is an actual nightmare. I use stainless steel litter boxes. Lifechanger. Easy to clean and the best. This litter however is closer to concrete mix than cat litter. It’s clumpy but it’s sticky when wet and adheres to my 3 cats feet and the walls of the litter box. I actually have to chisel it off with a sharpened paint scraper to even make a dent. It’s horrible. It’s just a clump of cement in 2 days and it smells horrible. I can’t even explain how much I hate it. Never get this litter. Every other option by this brand is great. If you want wet cement all over your fur babies feet and your floors and carpets this is the litter for you. I’d only use this if I wanted to build a retaining wall with a little sparkle in the mortar. I can’t see any other use for it. As a cat litter, Terrible. 0 stars.

Love this product tried going into detail about my experience
Size: 5 Pound
I could actually go a few days without doing the litter. It isn’t extremely easy to scoop the pee out it kind of doesn’t clump sometimes. But some of it does. It doesn’t smell like anything not perfumie but it does mask the smell of the ammonia. I couldn’t go more than a week before having to change all the litter in my box because I have three cats. But i can go 3 4 weeks without having to get completely new litter. And there is surprisingly a lot of litter in the bag. I have a VERY large litter box. And it is the perfect amount. I had wanted to try this crystal litter for a long time. And now that I did I’m extremely happy I did... I also didn’t get sludge on the bottom of my box I got hard buildup that I have to scrape off.. I used to get that with the normal litter anyway. Nothing new, i didn’t notice that it tracked less than normal litter. It got all over just like it always has.. lol it was harder to see when they were tracked through the house though.. so I wouldn’t be surprised if people who said it didn’t track through just didn’t see it lol. But I am def going to continue to buy this. I buy so much less litter now using this. And I don’t have to clean as much and it doesn’t stink as much. You have to just give it a try. As I said one bag was enough for my very large litter box for my 3 cats. :)

Incredible!
Size: 5 Pound
My older cat pees *a lot*, and all the clay litters we tried were not absorbing the urine, let alone any odors. Every time I cleaned the box, I had to scrape paste-like litter from the sides and bottom of the tray, which would then would fall apart and slide through the scoop, making it impossible to fully clear from the tray without doing a whole litter change. The smell was horrible, both ammonia and poo. Eww. I was skeptical of this letter, but willing to try anything after three years of nasty litter boxes. This product was incredible! I’ve been using it a week now, scooping every other day, and there is *no odor*! All the urine is tightly clumped and easy to scoop. It is surprisingly lightweight, and sifts so much easier than traditional litter. I also love how clean the tray looks. I’m already recommending this to my friends. I’m not sure how well this work if you use liners. A few urine clumps have stuck to the sides of the tray, but I can easily push them loose and scoop up (clumps don’t break apart). I don’t know if a liner would release these edge clumps as easily.

Something changed, and it wasn't just the bag
Size: 5 Pound
I LOVED this litter (5 stars) until a few months ago, but something changed and I can't imagine it's just the bag. Dust: - VERY, VERY dusty now. Lots of fine powdery dust stinging your eyes, mouth, lungs, etc, even with a mask on. So much powdery dust that it isn't lessened even with the gentlest/slowest scooping motions. I'm looking for a new brand now because I don't want this in my kitty's eyes and lungs. Tracking: - I used to get away with sweeping a few times a week near the box with this litter, but now I HAVE TO sweep there as soon as I get up every morning plus later in the day (crystals on the floor; not powder). It's still much less mess than with those heavy litters, but I wish this litter hadn't changed. Clumping: - This used to clump REALLY well (big urine clumps were easy to scoop out as a single chunk), but now the urine clumps disintegrate when I scoop them, so scooping is more of a hassle, the odor is worse, and the litter needs to be changed more often. Odor: - Used to have very good odor control with this litter. For me, still much better than the heavy litters but not as good now (see "Clumping") Weight - Very light! (Not like a bag of cement like some other litters)
