My cat's favorite liter

As a newer cat owner I've tried a number of litters as was disappointed. Some claimed to be scoop-able but would fall apart. Some claimed to reduce odors but even daily cleaning proved that wrong. Then I gave arm and hammer a try. It was everything I wanted. Almost no dust. Scooping is so easy as the clumps don't easily fall apart. And I could easily go a couple days without smelling it. This is now my go to and the only one I will buy.

It clumps perfectly

This is my favorite kitty litter. It stops all the odor from the litter box from hanging around. Even my husband, who seems to have a super nose, can't smell the litter box anymore. I love that it clumps everything very well, it's easy to scoop. Being able to scoop the pan everyday instead of doing a complete litter change, saves me money!!

Doesn't clump , very dusty

Did they change this formula ? I'm not sure what's happened but this used to be fine textured litter and worked so well. It was my favorite. I got this recently and it's larger rocks like the off brand horrible ones that don't clump and so much dust. I'm not buying this anymore.

Exactly True to Claims

I have tried a lot of different litters that claim to eliminate odor, but none work. I have always trusted in the brand Arm & Hammer, so I bought this litter. It truly does what is says. Perfectly clumps, seals odors, and easy to clean When comparing cost per ounce to other litters, it also comes out ahead. I have s very sensitive nose and low budget, but this litter is hard to beat.

Great product.

I love this product. Even though I only have one cat, I use it because it doubles the odor control. It really is 98% dust-free and clumps well for easy scooping, even though my cat likes to go on the walls of his litter box. :) For those who don't like walking on litter, beware, the granules are not tiny and are easily tracked, which I guess is my only negative comment.

Horrible odor

i bought this to try something different and sorry i did. The scent of the litter is terrible and when it mixes with the urine and feces it is horrible. Does a terrible job of covering up the smell. My home has a definite odor in it now that people notice and they never said anything before when i used tidy cats. Would never recommend this to anyone. People giving good reviews must be paid. The only good thing is it clumps well but the smell gives me a headache.

Great odor control!

I continue to buy this product for my kitties, it's easy to clean, it's low tracking, it's soft, and it doesn't stink up my entire house. Me and my kitten are in love!

Love it

I have bought this litter for years and absolutely love it especially for training new kittens. They just seem to go to it more quickly than other litter types for me. Very good at odor control as well as clean up.
