Litter quality is crap.

Hello, I thought I was going crazy but then I went to Reddit and saw this has been happening for over a year to other folks. (See pics of different color litters from diff batches) https://www.reddit.com/r/CatAdvice/comments/1f7n409/arm_hammer_litter_changed/ Your kitty litter products over the last year have gone from very good quality to absolute crap. They no longer control odors, ESPECIALLY urine, which has become eye watering while cleaning out the boxes lately. They don't clump well at all, the color and texture out of the box has changed from a lighter grey to a much darker grey color (which probably means that they either contain less baking soda now, or are not dried as thoroughly? which could explain BOTH issues consumers are having. I'm unsure of the ingredients and makeup of litter, but the product has really gone down-hill especially in the last couple boxes for me. Others have seemingly had this problem for much longer already. The most recent boxes I have purchased, from multiple vendors have all exhibited the same "new" look and lack of functionality. I switched to your product over covid time when prices of other litters went up, yours stayed reasonable and it was almost as good, but I and many other users are seemingly very disappointed in your products now and will most likely be switching away. Please look into this issue or I fear you'll be losing a lot more customers in the future.

The Right Litter for our Cats

I love Arm & Hammer products in general and this Double Duty Clumping litter just do the job perfectly for our home that has multiple cats. The clumping effect makes it easy to scoop. The odor control makes our home odor free even with multiple cats.

Not the same as it was

I have been using this cat litter for a really long time, and this is the first time I have poured it into the litter box, where it looks, feels, and smells like cheap dollar-store brands. It's much coarser than its usual fine texture. My cat smells of cat litter, no matter how clean the box is. Not sure if they changed the formula, but the box looks the same. We don't usually get the giant box, but we have since gotten a second cat, so we have two litter boxes now. I am VERY disappointed in this litter. Before this box, I would have given them five stars; it has always been consistent, but now I am nervous to buy again.

Changed formula or poor quality control, now sucks

I've been buying this litter for years since it's the only one my cat likes, but the quality control has severely gone downhill or they changed the formula. It's darker and has bigger rougher grains in the last couple boxes and my cat hates it. She'll go anywhere but her litter box now and it's been a huge waste of money since I'll never know which box has the litter she likes and which ones will have the litter she hates and the packaging is exactly the same.

Works Well

[This review was collected as part of a promotion.] I've been using Arm & Hammer Double Duty Clumping Cat Litter for a while now, and it's become my go-to. The odor control is excellent—both for urine and solid waste—and my house actually smells fresh even with two cats. It clumps really well, making cleanup quick and easy without the litter breaking apart. I also like that it's not overly dusty compared to some other brands I've tried. The only small downside is that it's a bit heavy when pouring, but that's a trade-off I don't mind for how well it works. Overall, it keeps my litter box area clean and odor-free—definitely worth it.

Bad litter

I never review cat litter brands , But this box of litter was really something. I emphasize it was something. The odor coming off of the litter reminded me of urinal cakes , literally my whole house smelled like that . The litter also wouldn't clump it was more like non scoopable. Please save your money and don't buy this litter.

Works great

Bought this product because my normal litter was out of stock and have decided I really like it. Clumps well keeps odors down and my cats have no problem using it. Will definitely be switching as this product cost less than the litter I was previously using. I am receiving points toward rewards in the Kitty Krew Community for writing this review.

Horrible soggy lumps

I switched from Fresh Step litter to Arm & Hammer because Fresh Step downgraded the quality of their litter and it no longer clumped but instead created a soggy lump. Now I 'm having the same issue with Arm & Hammer litter. I don't know if this is a quality control issue or if these companies don't care about their customers. Anyway, now I need to find another brand of litter.

Works Decent.

This works great if you've got more than 1-2 FurBabies. Sometimes it doesn't completely block out the odors but I just add a little bit of litter powder and it works just fine. "I am receiving points toward rewards in the Kitty Krew Community for writing this review. All opinions are my own."

Used for years!

I have tried so many different litter options. But, this is the one I have used exclusively for at least a few years. We have 4 kitties and go through a lot of litter and the Double Duty stuff works so well. I am receiving points toward rewards in the Kitty Krew Community for writing this review.
