The -only- cat litter for my 3 kitties!

We have 3 cats, so litter is a non-stop chore. I had always bought A&H in the past but tried afew different newer types when I took over litter duty. Just as in the past, nothing else scooped as nicely, or smelled better. In fact, I even tried on numerous occasions, the “Multi cat” version of this same litter and realized my mistake instantly as the odours were way more and when scooping, it would crumble and spread all over the box, meaning I needed to change the entire box instead of scooping and refilling in between major box changes. The cost of litter is atrocious so I want to get as long out of a box as possible. With the A&H double cat litter formula, paired with their litter box powder, I can scoop the three boxes every other day with no odours, and a box lasts me almost a month for 3 cats & boxes. There may be prettier/more environmental options out there, but there is no other option as good as this for duration and odour control. Period.

the Best Litter yet.

Been using A&H cat litter for years, but it never seemed to soak up the litter, it was always wet, & it would smell awful, that is until now, this new Double Duty litter is fabulous. Much nicer to work with & doesn't have that kitty urine smell. Great product

Opening the box

I am trying this litter out. It doesn't always clump well. The box is almost impossible to open. Takes 5 minutes with scissors trying to pry it open. By the time it's open the top of it is completely destroyed! Please fix the box. Will not buy again.

Have six cats---don't care for this product

As a caregiver for six cats I found this product less than adequate, it was bought because my regular brand was not available. Four boxes were bought and five litter boxes were filled with this products. The clumping action was fairly good but often the clumps with urine would fall apart as I was scooping it out. All my litter boxes are cleaned out at least once a day. As a Respiratory Therapist and Certified Asthma Educator I have concerns about the strong perfume smell, it is very potent. I will not buy this product again, I will hold out for my usual cat litter if I have to.

Glued so tight it was unusable!

I bought this and was very disappointed in the packaging. I COULDN'T GET IT OPEN! I'm 74 years old and it took me 40 minutes and all my strength to tear open a small opening. How dare you sell somethinglike this! I wish I could send you a photo. It's a mess now and my arms are shaking. It was a mistake to buy it.gwithout a way to get to it! I'm furious.

Does not work

I bought this 2 weeks ago and I have not seen a clump yet. It doesn't control odor and I only have one cat. It simply does not clump, I have spilled more on the floor cleaning the litter box, have not seen 1 clump. Very displeased with this product.

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.

Does not offer very good odor control!

I really like that this is a non-clay litter and leaves kess litter on the mat. However, the litter does not offer good protection from urine smells I clean the box 1-2 times a day and have even used the Arm and Hammer baking soda by mixing it into the litter. Still the smell persists. Please work on a better formulation for odor control.

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.
