INSTRUCTIONS FOR EVERDAY USE 1) Fill a clean empty litter box with 3 – 4 inches of ARM & HAMMER HardBall Clumping Lightweight Litter. 2) Kitty litter forms solid clumps. Remove clumps and solid waste daily to keep the rest of the litter fresh. 3) Add more ARM & HAMMER HardBall Clumping Lightweight Cat Litter to replace what you have scooped out and maintain a depth of 3 – 4 inches. Once a month, empty the entire litter box. SWITCHING WITH EASE TO HARDBALL CLUMPING LITTER: 1) Pour 1 inch of ARM & HAMMER Clumping Litter into a clean litter box and add 1 – 2 inches of your old litter brand on top. Do not mix; your cat will mix as it is used. 2) The next time you change the litter box, fill with 2 inches of ARM & HAMMER HardBall Clumping Litter and 1 – 2 inches of your old litter brand. Repeat this for 3 to 4 changes, lessening the amount of your old litter each time. 3) Fill the litter box with 3 – 4 inches of ARM & HAMMER HardBall Clumping Litter. At this point the transition should be complete! However, some cats do need more time, so don’t give up and repeat Step 2 as needed.

  1. Ann

    My litter box never smells! Easy to clean!

  2. Elizabeth

    I have 5 cats and they have smelly litter boxes until I bought Arm and Hammer cat litter for them to use! They’re not as smelly yay!

  3. Bailey

    Pretty Surprised at the Quality.

  4. Ravenkitty

    This litter is excellent

  5. Kathleen

    Not what I was looking for at least not for my cats

  6. LambkinLou

    Perfect addition

  7. SR

    The best litter I’ve used!

  8. Annette

    I changed to this because the one that I used for years just wasn’t clumping, this brand is working much better, less mess, I do need to use more deodorizer but that is a fair trade off for the better clumping power.

  9. Brenda

    I am on my 3rd box/bag of Hardball. The difference from clay litter is indescribable. Not only is it lightweight, it is easy to scoop in one pass with no small waste chunks left behind. Controls order better than any other I’ve tried.

  10. Kayla

    Very strong scent The litter works good hard balls very easy to clean but is very scented like it’s to much I’ve had to mix it with non scent litter to tone it done down a bit

  11. Librarian

    Not worth the price

  12. Amanda

    Odor free for days, less litter refresh
