Questions & Answers

7 Customer Questions

How is the dust?

Answer by Chewy • Apr 08, 2018
Ultra Pet silica gel litters have been tested to be 99.9% dust free.

Is this ok to use with 8 week old kittens?

Answer by Chewy • Feb 27, 2021
Silica gel crystal cat litter should only be used for kittens over 12 weeks of age – we recommend the Micro Crystals as it is “soft on paws”. Start with a layer of 2 cm deep (approximately 2/3 of an inch) and increase the litter depth as the kittens gain height and body mass. Kittens should be closely monitored when using a litter box as some will try to eat litter if unattended.

Is this product fragrance free?

Answer by Chewy • May 15, 2018
This litter is unscented.

Can u use this in an automated litter box

Answer by Chewy • Sep 14, 2020
As automatic litter boxes may vary, we recommend checking your litter box manual for litter specifications.

Didn’t work for me or my kitties!

It would stick to the bottom of the Stainless steel litter box. Difficult to clean. Y’all were out of your micro crystals and decided to give it a try. I still have one box I will not use. But I have ordered and received the micro crystals since you have restocked!

Really absorbs odor!

This is amazing! It’s a crystal litter that is also clumping. My cats love it. It’s easy clean up and not a lot of tracking. I’ve tried many crystal litters

This is amazing! It’s a crystal litter that is also clumping. My cats love it. It’s easy clean up and not a lot of tracking. I’ve tried many crystal litters and they all turn to a urine soaked sludge after a week. Not this brand! I love it so much I put it on auto ship so I don’t run out.

This litter does clump but it bonded to my litter box and would not chip off, I am having to replace all three of my litter boxes because of this litter, also even when my cats covered after doing their business there was big smell of urine. I will not buy again and do not recommend to anyone.

Clumping Scoopable Crystals

I thought the clumping scoopable crystal litter would work for us. As it turned out, the scoopable crystals was not cost effective for us. So much had to be scooped out each time. We went back to clumping grass litter by Frisco. It works fairly well. We did try the clumping crystal for a while. Just decided it wasn't cost efficient for us.

Clumping but not hard enough

I wanted to switch the litter to a clumping one and got this one. The crystals were smaller than I imagined (I was using PetSafe but it does not clump and the crystals are bigger) My concern with the size is the spilling and messy tracking. This brand clumps but when I pick up the urine clump they break apart into smaller ones that do not get picked up with the scoop. This is only the fisrt weekend with the change. I have 4 bags to try!

Best litter I've ever used

I've used some of the crystal litters that don't clump, but this crystal litter that clumps stays so fresh. I love how it looks clean and how it stays odor free

I've used some of the crystal litters that don't clump, but this crystal litter that clumps stays so fresh. I love how it looks clean and how it stays odor free. My cat doesn't track it and my house doesn't smell like a litter box.

Micro, clumping, and unscented

For some reason it’s getting harder to find micro litter tnag clumps and is also unscented. Our usual go to litter seems to be discontinued, so I got this since

For some reason it’s getting harder to find micro litter tnag clumps and is also unscented. Our usual go to litter seems to be discontinued, so I got this since it’s almost impossible to find what I’m looking for other than this one. It works good and clumps well (some other brands the urine doesn’t clump well). It doesn’t smell or have any scent which is great for my cats and is easy on their paws. My only reason for giving it 4/5 stars instead of 5 is because the bags of litter are very small. I need to use 2 bags just to fill the litter box up enough.

I think this got switched with the non clumping kind.

I got this purple bag, but there is zero clumping of the urine. I think maybe the wrong litter was put into these bags. I don’t mind trying the non clumping this

I got this purple bag, but there is zero clumping of the urine. I think maybe the wrong litter was put into these bags. I don’t mind trying the non clumping this month, but I find when I use the non clumping kind the urine smell starts to stand out more than the clumping. However, it’s nice to not have to trying to scrape the little concrete clumps off the sides since I have a cat that insists on peeing on the very back of the litter box.

It clumps and it's crystal!

As far as cat litter is concerned, I have been disappointed consistently over the years ive been on the planet. Then they crystals came out and were wayyy too expensive

As far as cat litter is concerned, I have been disappointed consistently over the years ive been on the planet. Then they crystals came out and were wayyy too expensive and had a downside, no clumping. Until now and this price is not terrible either. Ive been waiting a lifetime for this litter. And my cat thanks you!
