5.0 out of 5 stars The unscented is the best way to go
Reviewed in the United States on October 24, 2023
I purchased the lavender scent before this one. This is so much better! The unscented neutralizes the pet odor so much better and our cat loves to kick up her kitty litter and this one clumps up very well do avoid big messes. It has a bit of a clay scent but I'll take it over the lavender any day

5.0 out of 5 stars My favorite litter- great for people with disabilities
Reviewed in the United States on November 10, 2023
As someone living with disability who also loves their cat very much, this is life saving. Sometimes it's difficult to scoop her litter every day, but this litter prevents odor on days I don't have the energy for cleaning.

It clumps perfectly, prevents odor well (for being unscented), and is super easy to clean. There is a little dust, but not nearly as much as other litters. The price is good and I'm really happy with this.

I will definitely be buying more.

It still doesn't smell too great (like 99.99%of cat litters) but as cat litter goes it clumps pretty well and is easy to clean. It's a bit heavy and there is a little bit of dust as to be expected

5.0 out of 5 stars Arm & Hammer Ultra Last Unscented Clumping Cat Litter Review
Reviewed in the United States on April 25, 2024
After trying out several cat litters, I recently switched to Arm & Hammer Ultra Last Unscented Clumping Cat Litter, MultiCat, and I'm pleased with the results.

One of the standout features of this litter is its strength. It does an excellent job of controlling odors, even in a multi-cat household like mine. The unscented formula is a plus for me as I prefer to avoid artificial fragrances in my cat's litter. Despite being unscented, it effectively neutralizes odors, keeping my home smelling fresh.

The clumping action of this litter is impressive. It forms tight, solid clumps that make scooping easy and efficient. This helps to extend the life of the litter, as I can remove waste without having to discard large portions of clean litter.

I also appreciate the dust-free formula of this litter. It minimizes dust clouds during pouring and scooping, creating a cleaner and more pleasant environment for both me and my cats.

Overall, I'm satisfied with Arm & Hammer Ultra Last Unscented Clumping Cat Litter, MultiCat. It's a reliable option that provides strong odor control, tight clumping, and minimal dust. I'll definitely be purchasing it again in the future.

3.0 out of 5 stars Fails to live up to expectations
Reviewed in the United States on February 22, 2024
Unfortunately, the performance was disappointing. Despite the inclusion of baking soda, which I expected would neutralize odors effectively, the smell still permeates the room, challenging the claim of being pet-friendly.
The clumps, rather than staying solid for easy scooping, fall apart, making clean-up a frustrating and messy task. This issue compromises the cleanliness of the litter box and requires more frequent changes than anticipated, diminishing the product's value.

5.0 out of 5 stars Best litter I’ve tried
Reviewed in the United States on May 2, 2024
We live in a small apartment with two cats and a toddler. I vacuum twice a day normally, and it’s no different with this litter. But it’s far more sequestered to the area around the box. It doesn’t stick to my cats feet and get on the bed/couch which is so important trying to keep things clean with a one year old that puts everything in their mouth. The clumps are very tight and easy to scoop. It falls apart much less than other litters. It’s easy to forget to scoop but we get around 3 days if I’m not on top of it before it starts to stink and by that point it would be a disservice to my animals to not clean it and expect more odor control than that. There’s very minimal dust which was important as one of my cats will sneeze a lot with a particularly dusty litter. I feel like I’ve finally found the perfect litter after years of trying to find the best. It is not sticky at all which is so important, as I’ve found stickiness to be correlated with clumps falling apart which has not been my experience with this litter.

It's great for those kitties and owners with dust allergies, no worries about that with this litter. It's clumping makes it easy to clean up, after kitty's business, and no smell to make you gag, while you clean. ????

1.0 out of 5 stars Smelly And Sticks To My Cat
Reviewed in the United States on June 11, 2024
I clean my cat’s xl litter box daily. This is the first litter I have seen that actually holds onto the urine smell and amplifies it, (I always use unscented litter). When I poured it into the box, so much dust poofed into the air! It settled down all over my bathroom. The litter smelled so strong within two days of use. The clumps fall apart and make mini-clumps that my scoop can’t get. It sticks to the bottom of the litter box and I have to scrape it off.

My medium hair cat isn’t a litter kicker so it was a huge surprise to find this all over the floor, even with a litter mat. When I found it stuck to his fur, it was the last straw. I bought different litter and swapped it out.

HUGE WASTE OF MONEY and possibly hazardous to my cat’s health.
