Our favorite!

Started using this litter when my cat was just a kitten, he's two now (going on three soon) and i have no complaints! The smell for me has always been unnoticeable, unless you go a while without cleaning of course. 10/10 will continue to use!

Love this product

I've been using this product for about 15 years, and every time I do, I still like it. It is low dust and low tracking. The scent isn't too strong or overpowering. It is just enough to cover and mask over urine and fecal odors long enough for me to get around to scooping each day. It's definitely been a helper in our multi-cat household.

Doesn't clump, waste of money

This litter was great, tight clumps made cleaning the boxes easy, but you must have changed the formula because it DOESN'T clump at all now. The litter just gets wet and is such a waste now. Again, it does not clump at all, not even a little. Before it was great and easy to clean so there was no smells left behind. You can not put incorrect info on the boxes, false advertising now.

Works Great

I find ARM & HAMMERâ„¢ Naturals clumping litter offers an environmentally friendly option with low dust and easy handling. However, its clumping ability and odor control may not meet the needs of every and all cat owners, particularly those with multiple cats or sensitive felines."I am receiving points toward rewards in the Kitty Krew Community for writing this review.

No dust

I use this litter for my 2 cats and like it very much. The only thing I don't like is that sometimes my cats step in their pee and get it on their paws. I wish somehow the urine would sink towards the bottom so kitty paws didn't pick up litter and urine

me and my kitty LOVED it

I bought this today because my cat ran out of litter, and he LOVED it. no trace of litter around the house because it's small pellets that don't get stuck in their toes. and it smelled so good. the clumping part was fantastic and it didn't crumble when picking up. 10/10 would purchase again!

Double Duty Scented 40lbs. Box

I love Double Duty Scented Litter and my cat does too until recently it changed. It used to be light in color with sand like granules but now is very dark in color with slightly larger granules and my cat nor I like it at all. Why did you change it? I was a huge fan of the previous formula but now not so much anymore and will be forced to a new product that is more like before. This is so disappointing to me and my cat.

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.

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.
