Once a month, empty the entire litter box. Dispose of used litter in trash. Do not flush or put in drains.

    • FINALLY No dust
Size: 37lb – Frustration Free Pack Style: Cloud Control Platinum Clumping Litter
This is hands down the best litter I’ve ever used. We currently have 3 kittens, and have had other cats in the past so I have many years experience with pretty much every brand and type out there. I was using Fresh Step with these kittens at first, as I liked the odor control and got a good price on it at BJs. Sometimes we also used the sister-and very similar- product Scoop Away. Both of those seem to have become dustier over the years. So much so you can see clouds of it, also I was getting a tightness in my chest after daily scooping. I became worried for my fur babies lungs. Also one of our kitties seemed to have an allergy to it and was constantly itching after using the box. We now use 2 XL stainless steel litter boxes with this litter exclusively and couldn’t be happier! I was hesitant to try this since I found most A&H litters too heavily scented in the past. So much so that I felt the house smelled of litter ( not the cats business but the litter itself). This one has a light scent but is in NO way overpowering and I actually quite like it. This stuff is basically a sand consistency.. It’s softer on their little paws. This also helps with tracking as it’s so small you don’t have balls of clay tracking all over the place. I use a Dustbuster outside the boxes daily, and along with the step/catcher that came with the boxes we have zero tracking issues. Kitties had no problems transitioning, I think they actually prefer this litter. The baby that was itchy is no longer itchy. As for odor control- it’s even better than most other brands. I normally sprinkle in the Rocco & Roxie litter deodorizer which was a necessity with some litters. I haven’t needed to do so with this one, unless one of them has an exceptionally bad poo day lol Only negative is the cost. It’s more expensive and at first I didn’t intend to continue using. I got it on sale and was desperate since my one baby seemed allergic to the last litter. I’ve since bought 3 more boxes. It lasts longer as the clumps stay harder and nothing really sticks at all. And my kittens like to dig a hole to China before going 🤣 So I feel the price evens out. Hope this helps anyone sick of dusty, high tracking clay litters! ... show more

    • Great Litter
Size: 37lb – Frustration Free Pack Style: SLIDE Platinum Clumping Litter
This litter is excellent quality and absolutely delivers when it comes to clumping and odor control. The clumps form incredibly fast and are extremely tight and solid, which makes scooping very clean and keeps smells locked in. You can really tell this is a premium litter—the odor control is strong even in a multi-cat setup, and it stays effective for days without that stale litter smell. If odor control is your top priority, this litter does an impressive job. That said, the clumping is so strong that it can be almost a little too hard. Because the clumps set up so firmly, they can sometimes stick to the bottom of the litter box if you don’t scoop quickly, which means you may go through litter faster than expected. Still, that same firmness is also what makes it such high quality and keeps messes from breaking apart. Overall, it’s a great value for the performance you get, and if you don’t mind scooping regularly, it’s one of the best clumping litters I’ve used. ... show more

    • Best litter I’ve tried in my Litter-Robot 4
Size: 37lb – Frustration Free Pack Style: SLIDE Platinum Clumping Litter
I’ve been running a Litter-Robot 4 for about a year with two cats, and I’ve tested quite a few litters to find one that performs well inside the globe without causing issues. I switched to ARM & HAMMER Clump & Seal SLIDE Platinum Multi-Cat about two months ago and it’s now the clear winner for my setup. The “Slide” non-stick technology really lives up to its name in the Litter-Robot. When the globe rotates and dumps the clumps into the drawer, almost nothing stays stuck to the interior liner — I rarely see any residue left behind after a cycle. With previous litters I’d often get bits of clay or softer clumps smeared on the walls or stuck in the sifting holes, which meant occasional manual scraping. With this Platinum version that almost never happens. Cleanup of the globe itself is noticeably quicker and easier. Clumping is strong and fast — urine forms tight, hard balls that hold together perfectly during the rotation and drop cleanly into the drawer. I scoop the drawer every 4–5 days (two cats, average usage), and the odor stays very well controlled the whole time. The combination of baking soda, odor eliminators, and the sealed drawer means the house doesn’t pick up any ammonia smell even toward the end of the week. Dust is very low when pouring into the unit (important since the LR4’s entryway can kick up dust if the litter is powdery). Tracking is also minimal — my cats don’t carry much out onto the mat or floor. The only small observation is that in very humid conditions the clumps feel slightly less rock-hard when they hit the drawer (still scoopable and solid, just a tiny bit softer), but it has no real impact on performance inside the Litter-Robot or on odor control. For anyone using a Litter-Robot 4 (or similar self-cleaning box), this is hands-down the best clay litter I’ve found so far. It maximizes the machine’s strengths: clean rotation, reliable sifting, low maintenance, and truly sealed odor control. My cats use it without hesitation, the unit stays cleaner longer, and I’m spending less time dealing with litter hassles. I’m not planning to switch unless they discontinue this exact formula. 5 stars — excellent match for the Litter-Robot 4 in a multi-cat home. ... show more

    • The best-ever litter; NO dust!
Size: 18 lbs Style: Cloud Control Platinum Clumping Litter
This litter is fantastic. There is absolutely NO DUST. It clumps very well and covers odors. I will warn you that the boxes are HEAVY so be aware of the listed poundage when ordering. A couple of times I ordered two boxes at once. The first time the delivery was cancelled. The second time the box arrived battered and was labeled with a HEAVY warning. I felt so sorry for the delivery person! I now order one box at a time and am very grateful it is available since my grocery store is often sold-out. ... show more
