Switching from A&H was a BIG mistake!

I've been using A&H double duty cat litter for years. Recently I switched my 2 cats litter to Tidy Cats. What a mess! The entire office as covered with fine dust. All over my printer, pens and markers, sewing machine, etc. and you can't dust it because too fine of a dust. Have to literally wash everything. Which I had just spring cleaned that room right before switching to Tidy Cats.

Performs well & is economical.

I had been using another Arm & Hammer litter and was very pleased with it, but I was looking to make a change (tightening the old budget!). I was very pleased to find this at my warehouse club. It's been great. Kitties have adapted quickly to the change & MamaCat is saving money. And I notice no difference-the odor control is great. thank you A&H!

I've been using this litter for 3/4's of a year and it is genuinely one of the best litters I have dealt with yet. My 14 year old retired farm cat doesn't complain about it, the clumps are easy to scoop, and while nothing will fully cover his stink this litter does a fantastic job of making that odor disappear promptly. In this house, we go though quite a bit of litter each month so the 40lb option is exactly what I need. I will always recommend this litter to all fellow kitty owners!

Great Clumping

I had never tried this kind of litter before but always wanted to. I am hoing to earn points for the Kitty Krew rewards orogram but my opinions are my own. I enjoy the long lasting smell of this litter and how it clumps in solid pieces for easy scooping.

Greatest Cat Litter Ever!!!

I have been buying Arcat is 6 years old now and Arm&Hammer cat litter for many years. My cat is now 6 years old now and will let me know when it is time to clean her box. I clean it every day and there is never any oder People come in my house and don't ever smell her box. I love this brand of litter. Great price too.

Odor control 3 cats

Husband bought it. I really like it for odor control. We have a litter robot and a second standard box. The standard box always use to smell. Now this is being used and I actually forgot to change it since I didn't smell anything. Thank you for the double duty. P.s. there was a place to bullet #2 that offered a photo option. There doesnt appear to be place to do so. As a proud owner of 3 Sphynx cats I'd love to share a pic or 3 ;) Thank you !

Great product!

I've owned cats most of my 72 years. I am currently the proud momma to five cats. I use Arm & Hammer Double Duty cat litter and will NOT use anything else! I recommend it whenever someone inquires. When visitors come to my home, they always comment how they didn't realize I had a cat, let alone five, until they came around, because they don't smell a litter box and are pleased to see how clean everything is (low dust, no tracking). None of my cats have ever peed or pooped outside of their litter pan; unlike several of my family and friends have had their cats do. I do have one litter pan per cat and clean them once a day. I use the Army & Hammer shifting litter pans. I wipe them down with an Arm & Hammer disinfecting wipe. It takes me less than 10 minutes to clean them all.

Great clumping technique

I really love this litter but after a while. You can smell the cat pee while cleaning the litter box. I add more but the pee gets stronger and stronger. But over all I give it a 3 cause it does clump and some what seal. Not ever litter is perfect but I wish this one was. The pee doesn't stick to the bottom of the litter box

Changes in Litter to push higher cost alternatives

I've used this litter for years and suggested to others that it is great. Not anymore. It has stopped clumping, is not controlling odor (and I scoop twice a day) and is now a disappointment. My husband took care of the cats for a week while I was gone and he noted the same problems without prompting. And the suggestion is to switch litters? Clump and Seal is $10 more a box. If I have to change litter it won't be within the A & H family

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.
