A lightweight kitty litter with virtually indestructible clumps? Introducing NEW ARM & HAMMER HardBall Clumping Litter. The innovative formula works in a new way: to quickly shrink cat waste and odors into ultra-compact clumps for easy, no-mess scooping. Our Lightweight Perfected Platinum Formula (online only) is over 60% lighter than our regular cat litter YET is highly absorbent to form hard clumps. A clean Garden Bloom scent offers 14 days of odor control guaranteed! Purrfect for multiple cat homes.INSTRUCTIONS FOR EVERDAY USE 1) Fill a clean empty litter box with 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.

Awful!

5 days ago
Wow! What happened to this product? I used it faithfully for 3 years without problems, but the last three bags have been awful! It no longer clumps into hard balls. It barely clumps at all. The urine just sinks to the bottom of the pan and turns into a concrete-like layer of goop that has to be pried from the litter pan with a wide putty knife. I will be searching for a new brand of litter when my current supply is exhausted.

No, I do not recommend this product.

Incredible but need an unscented one!

6 days ago
I’ve been using this litter for two years. It’s the best cat litter I have ever purchased. It’s easy to scoop, lasts for ages, doesn’t stick to the bottom of the box. But I am BEGGING for an unscented one. I have one picky cat who won’t use it and only likes unscented litter so I have something else in her box and every time I have to scoop it, I dream of an unscented hardball.

Hardball™ Clumping Cat Litter is made from U.S.-grown sorghum. There may be natural variation in the litter’s color from batch to batch but its performance and clumping power is the same. We still would like to follow up. Watch for an email to arrive soon!
