Terrible Cat Litter

This is my first time purchasing a Arm and Hammer Cat litter and it's definitely a disappointing purchase. Litter is everywhere, does not have great odor control as advertised. I pick up litter and the next day, the bathroom still stinks. Does not clump urine well and does not control odor. When cleaning the litter, my nose is literally burning on fire from the ammonia.

Best Litter I've Used

I've been using this litter since I got my kitten last year and I love it. It does a great job trapping odors and for those with kittens know that kitten poos are dangerous. It clumps up well and has minimal dust when cleaning. Would recommend to all cat parents

Great clumps, pleasant scent, happy cats!

Have been using Arm and Hammer Double Duty for many years for our multi cat home in 3 of 5 litter boxes 4 of the cats prefer the Double Duty boxes , 1 prefers traditional clay. I prefer Double Duty as it clumps quite well, has a pleasant scent that the cats do not find offensive.

Good price for good quantity & quality

We have 3 cats & 3 big litter boxes (about to be 4 boxes) and the 40 pound box fills all 3 and if you properly maintain your litter boxes on a daily basis, it will last a month or more!!! I do recommend this to anyone with multiple fur babies kitties 😸 💕 "I am receiving points toward rewards in the Kitty Krew Community for writing this review. All opinions are my own."

Great choice for 2

[This review was collected as part of a promotion.] The only kind I'll use for my 2 babies. Easy clean up and smells good

Favorite one from all litters I've tried. Doesn't smell rancid, as long as you keep up3-4 days at least

Too expensive not to work

This litter doesn't do what it claims! The cat pee doesn't clump and the cat box stinks. I had to dump everything out and start over

Way too strong

It does really well but the smells of the scent is extremely strong. If you spend any amount of time in the room with the litter box, the smell is in your clothes. It's WAY too strong

The best yet

This is my favorite cat litter to use! It smells great, an the great scent lasts between litter changes. It's easy to scoop out, it clumps almost immediately. It's great!

Cats favorite Litter

One of my cats favorite litter. Clumping and sealing in hard clumps makes scooping easier. I'm receiving points towards rewards in the Kitty Crew Community for writing this review. All opinions are my own.
