Formula Change?
I have used this for years and felt it did a better job with odor control than tidy cats. However our cat developed a sudden allergy and the only thing it can be narrowed down to is this and I’m assuming a formula change. It was noted on another website also that customer reviews have noticed a sudden difference.

Double Duty Has Become Horrible
Been using for years now. However, the last 2 boxes I bought have been absolutely horrible. The litter does not clump cat all but rather creates a large sludge that seems to glue itself to the bottom of the litter box. It is disgusting to clean and necessitates a huge quantity of the litter to be scraped out each day. This also results in using up the litter at twice the normal rate.

Cheap, stinky and not good!!
I switched litters because this one was cheaper and I could tell why. My place smells, it clumps up, you use about a box every week or so. What a waste of money.

Fix your manufacturing issue!
I’ve been buying this litter for 3 years now. I’ve always been happy with it until about a year ago when I bought a 40lb box that ended up being a very different litter than I was used to. It was Dark colored and had no odor control. Since then, almost every other time that I buy it, it’s not the right litter or quality that I’m used to. Something is going on during manufacturing of this product and I will no longer be buying it.

Already clumpy
I emptied into litter box and clumps fell out. I couldn't believe it. I would have given 0stars if it had been possible.

No clumps at all
It didn't clump at all. I just cleaned the litter and had to throw away 40lbs of litter cus all of it was soaked from urine. None of it had clumped up. It was all soggy and wet. And the smell was extremely stringent! So much for urine control or neutralizer.

Excellent litter.
Switched to Double Duty and it solved all my clumping/shoveling issues. This is the one I use now.

While this does a good job at not tracking all over the house, it does a terrible job at masking smell. My cat will use the bathroom and I can smell it immediately and it lingers even after cleaning somehow, you can smell the litter from the other room with this litter.

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.
