Skip this litter

I recently switched back to arm and hammer double duty thinking it was just as good as the more expensive litter I had been using and was insanely disappointed. Literally created a cloud of dust each use and and a dusty film covered the litter box and then was tracked all over the floor… little dusty cat prints on all the floors and even on the bed when she jumped on. I don't ever remember a&h being like this and was sooooo disappointed. For being only $5 cheaper than Dr. Elsey, it's definitely not worth it and I will not be buying again.

One of the best

One of the best brands I've ever used. If you haven't tried it then you need to. Russian Blue and Calico both use it and it completely covers the smell and clumps are solid and don't fall apart compared to others. Pick one up if you haven't tried it.

NOT A CLUMPING LITTER!

I'm a happy person who likes to give products and people the benefit of the doubt BUT, I just bought this product from my grocery store. It is the worst cat litter I have ever used - in over 25 years and 5 cats later! Do NOT buy this if you expect a clumping litter. It does not clump. All you'll get a litter box full of urine puddled on top of this litter - all wet. Arm & Hammer should be ashamed to put their name on it.

Great litter turned BAD!!!

I have no idea why you changed your formula! This cat litter used to be a fine, beach sand like litter that would actually clump and hold together and had fantastic odor control. The last several boxes I bought have had larger, fine gravel like litter that doesn't clump well or hold together, and the odor fighting properties are nearly non-existent! I had continued to buy this litter after I noticed the change hoping that I had just gotten a bad batch. That no longer seems to be the case, as several months and boxes later the litter remains the same new mixture. I may as well buy a brand (which I won't name here) that costs half the price, and performs exactly the same as this new formulation does (meaning it doesn't perform at all). What a shame. I have used this litter for 9 years and absolutely loved it! Guess I'll be finding myself a new cat litter to use.

Best litter there is!

I used to use another brand, we went to stay with a family member for a few weeks & he was using double duty. We had my 5 cats plus his cat all using just 2 litter boxes, & as long as we scooped the offending matter out each morning, you couldn't even tell there were cats in the house. I immediately switched & have been using it for over a year now & won't use anything else!

Great litter

The best cat litter ever. This is the only one I buy. I have 2 cats and it is low odor, low dust and the clumping works great.

Great smell

We have 5 cats, and this arm & hammer double duty has kept our home smelling like we live in a cat less home. The only litter we buy.

Cleaning is easy!

I but this for my cat any time I need new litter. It makes cleaning very easy and doesn't Smell (unless you don't change/clean it regularly).

Great litter

I have used this litter for years now and see no reason to change. The odor control is great and no problem with dust.
