Questions & Answers

3 Customer Questions


Can this litter be mixed with clumping litter?

Answer by ChewyJul 25, 2023
This litter should only be mixed while transitioning your cat to the new litter. It is not recommended to continue mixing litters as it will interfere with color changes.

What country makes this? Where is it resourced?

Answer by ChewyFeb 17, 2025
This litter is sourced and manufactured in the United States.

Is it toxic to cats if they lick their paws and its on there?

Answer by ChewyJan 28, 2025
The safety of all raw materials used in our litter is determined by a thorough review. The review entails evaluating the levels of raw material used in the litter, different methods of exposure and established health hazards. Based on their strenuous review, they can say with confidence that their products, when used as directed, are not expected to pose a hazard to humans or pets.

awful litter

This litter was AWFUL. It basically started stinking after they used it once. It didn’t even last a week before i had to change it, as the smell was just unbearable. I will definitely not be buying this again, and I heavily recommend you don't either. I will say, it DID change color when my cats with kidney issues peed in it, so that at least seems to work. Maybe if you use it just to check if your cats urine is okay it would be fine, but definitely dont use it as a regular litter as it will make your house stink to high heaven.

Dramatic price increase

While the litter is fine. The 6$ price increase per bag is not. I had this on autoship, 4 bags at a time, and my previous shipment cost 75$, the very next shipment cost almost 100$. Without warning or notification, without improvement to the product, and for the same amount. Not to mention this is the second time this has happened with Chewy where I had to switch products due to dramatic price increases, and with a very picky elderly cat this is not right. What on earth warrants a 6$ price increase per bag??!! Not happy.

Immediately turned yellow on top and blue on bottom after our cat used it. With a history of urinary blockages and surgery for the same, we weren’t messing with our cat’s health and made an appointment and got a urine sample. Obviously he was fine and the litter continues to react the same way. The vet says they do get lots of urinalysis requests due to the same issues. Very annoyed we paid for expensive litter that didn’t work and cost us more money. Also our tolerant boy who has never complained about a litter or food, hated this litter. He would go in and leave the box (another reason we got the appointment and didn’t immediately think the litter was wrong). He eventually used it, but as soon as we put the regular clumping litter in his very small spare box, he hasn’t gone back into the one with crystals. Very disappointed.

Spent tons of money at the vet, and the antibiotics didn't work. Bought a holistic remedy, and used this litter to determine if uti was still active. After giving her my holistic choice, her uti cleared up, and this litter determined it was gone. She is a much happier cat!

We like the cleanliness of this product, where only the poop has to be removed, and the rest of it can be stirred to release the urine to evaporate. There is no odor and virtually no dust. It’s well worth the extra price.

This litter was extremely dusty. I must hold my breath every time I scoop the poop. I will not buy this brand again.

Dustier than anticipated. Tried this out for a few months as a PetSafe Crystal replacement because it was cheaper. Not going to reorder.
