Questions & Answers

8 Customer Questions


Will this work in a self cleaning litter box?


Why has Boxie Cat litter gotten unusually dusty and changed color (gray to tan) recently?

Answer by YMMMJul 02, 2026
This happened to me a few months ago too. I complained and they replaced the bags, and even though they were still the tan-colored ones, they weren’t dusty at all. I also feel like this batch clumps better.

Does this litter stick to the pan?

Answer by ChewyAug 18, 2019
This litter forms hard flat-top clumps that form instantly on the top of the litter box, making them easy to scoop.

Do you offer the 28lb bag?

Answer by ChewyDec 24, 2019
At this time, this formula of litter is available in a 16-pound bag and a 28-pound bag.

New sand color formula is bad

I used the Boxiecst extra strength for the last couple of years. It was expensive, but it worked. It clumped well, on the surface and did great job with odor control

I used the Boxiecst extra strength for the last couple of years. It was expensive, but it worked. It clumped well, on the surface and did great job with odor control. The litter that was tracked outside the box was large enough pick up and soft. A couple months ago our delivery brought a new litter in the old packaging. I thought it would have the same qualities as the gray litter. I was very wrong. The new litter is fine sand that tracks everywhere and just like beach sand is very hard to get all of it. The clumping on the surface is gone. This new litter does a good job at drying the poop, but the clumping for wet stuff is terrible. The pee pools at the bottom of the litterbox and the clumping is weak and when you try to scrape the box it breaks apart in pieces that fall through the scoop grill. The odor control is also gone. My litterbox that gets cleaned twice a day stinks up the entire laundry room, and hallway, where with the gray litter I could scoop once a day and you wouldn't know it was there. It should be illegal for a company to change its product to such a degree that it's a new, inferior product and still take advantage of the brand and premium price of the old product. The sand colored Boxiecat is not worth it. I'll need to find a new cat litter.

This cat litter is all that it advertises in the name! My favorite part is the low dust and scent-free feature. I can have the litter box in the same room as me, without worrying about the dust and the smell. If the cat is actively going to the bathroom, then yes you will smell the poo, but only until the cat covers it up. The part I don’t like about the product is the bag the litter comes in. The bag does have a handle on the side to help pour it, but it felt like it would break while using it. Also, there is a sticker to close the bag, that works as expected. Another great thing about this litter is that it doesn't get tracked around the house. The clumps are great, especially with urine. I think my cat approves because he laid in the litter box as soon as I added this litter for the first time,lol.

Decent litter!

I’ve only used one kind of cat litter for my cats. So, I was a bit skeptical to try something new. I can say there is zero smell after the cats have used their box

I’ve only used one kind of cat litter for my cats. So, I was a bit skeptical to try something new. I can say there is zero smell after the cats have used their box. The litter also clumps well around the urine and feces. The litter also doesn’t stick to their feet as much!!! My only complaint is it’s much heavier than the usual litter I purchase. That makes it more difficult for me to scoop and move the litter around the box.

I love this litter for order control and clumping but it tracks everywhere!! After using it for a few months I have to change litter brands. I have never had my cats track litter through my house like this stuff does. Thanks to this litter I can see every place my cats have walked or laid in my house because some of the litter is left behind when they leave. On couches, on beds, on tables (that they shouldn’t be on). I’m so tired of sweeping it up every time they step out of the litter box because there’s a big trail. If they ever fix the tracking problem I’d try it again but I can’t stand it any longer.

I'm torn so choose wisely

I'm stuck bc I used worlds best for years my cats used it no issues. I was "influenced" to try this litter out and man did my cats love this way more! It does clump up pee/poop like it says. Oh if they pee in same spot it will pool up on top so you'll have to pour more litter over it to make it clump... here's the worst.. It does not help with odor control like not at all. The cleaning is mess. This litter gets stuck to my stainless steel pans sooo bad where ever they pee. It also gets stuck on the scooper horribly to where I'm outside with the hose cleaning it. It's a big task cleaning the litters now a days. Also this litter bc it is so fine you can't really see it being tracked all over your house until you vacuum or until you see it on your couch or bed. I tried to go back to world's best but they wanted nothing to do with it!! I really think they just like how the very fine litter feels on their feet. So thus I'm torn. Make the choice wisely cat parents.

Extra Strength for 2 Cats Works well!!

I used the regular formula and had to use the extra strength once due to limited availability. I’m glad because it works really well & I don’t want to go back to the other nixie formula. Also, one of my cats is weird and rolls around in the litter box. I like knowing she is somehow getting some probiotics from that haha

Throughout the past 25 years I have used three well-known commercial brands of litter for the different cars I have had. By far the Boxiecat Extra Strength Odor Control Clumping Clay is the absolute best product that I've used. It was recommended to me by an independent small business. Unlike other products I've been using, this product does not cause a wet, sticky paste on the pan (thank Heaven!), it fully clumps instead of leaving behind small clumps which slip through the scooper, it really is dust free (my experience despite some of the reviews here), very low tracking compared to any product I have used, doesn't stick to the cat's paws or legs, and controls odor unlike anything I've used. No more ammonia or other smells. I rarely have to dump the litter and clean the box like I used to. I highly recommend that you give this a try.

I don’t usually write reviews but I feel this cat liter deserves to be bought by everyone that is deciding to purchase it. I use to use Crystal cat liter. It was expensive but worth it. I then tried this cat liter and nothing compares to ANY other kind. It clumps right away and when you scoop it up nothing falls through. I have not changed my liter in a month and no smells. It also does not stick to the bottom like all other liters. Great price! Worth every penny spent. Try it and you will absolutely agree. I will NEVER try any other cat literally.

When I bought the blue bag, I didn’t realize it was for automatic cleaning boxes, which I no longer have. I have a large stainless steel box high sides. We poured this litter in the box. There was absolutely no dust. It does track, but not as bad as other cat litters, thebest part is the way the urine stays on the top of the box clumps hard, very easy to scoop and since you keep 3 inches cat litter in there, my cat is now digging and bearing her business again she couldn’t do that in the automatic litter box, but this is this cat litter is everything that it advertises to be it’s expensive, but it’s worth penny to keep the people that I live with happy

I was using this for over a year. Searched high and low for good litter for my litter robot. It was good till it really really wasn't. It forms a wet cement like substance that doesn't ever really dry out. I have had to scrape the heck out of it to dislodge it. On my cats feet like glue. It doesn't mask any odor anymore. I have to do a massive deep clean on my robot. My cats are not happy and I am not either. Never again. I don't even know how to dispose the almost full bag now.
