Learn how to set up the Arm & Hammer Large Rimmed Wave Litter Box for less scatter and easier cleaning, with a step-by-step routine that works for high-sided cat litter boxes.
Quick answer
Place the Arm & Hammer Large Rimmed Wave Litter Box on a level, easy-to-reach floor spot, fill it with 2–3 inches of clumping litter, and scoop daily while wiping the high rim weekly. The rimmed design helps contain scatter and urine spray, but only if the box stays clean and stable.
Why the rim and low front matter for daily use
The raised rim on this box is its main practical feature: it gives litter room to fly without landing on your floor, and it helps keep liners in place if you use them. The low front entry is equally important—it lets cats step in without jumping, which matters for older or smaller cats. Together, these features make the box a good fit for cats that dig hard or spray urine upward, but they do not replace daily scooping. A high-sided box with a dirty bed will still be avoided.
Where the box works best—and where it doesn’t
This box suits households with a cat that kicks litter or urinates high on the sides. It is less ideal for a cat that refuses covered boxes or needs a very low entry due to mobility issues—the front is low, but the overall box is still large. Also, the rim helps with scatter but does not seal in odors, so place it away from food and in a ventilated area. If you have multiple cats, provide one box per cat plus one extra; the large size helps, but sharing one box can cause stress.
Step-by-step setup and care
- Choose and prepare the spot: Place the box on a level, hard floor in a quiet area away from food and water. Avoid carpets or rugs that can trap scattered litter. Common mistake: putting the box in a damp basement or next to noisy appliances—cats may avoid it. Check that the box sits flat and does not wobble; a stable box feels safer to jump into.
- Add litter to the right depth: Pour 2–3 inches of clumping litter, enough for digging but not so deep that it spills over the low front. Common mistake: overfilling—this defeats the rim’s scatter control and makes scooping harder. Leave at least an inch of space below the rim so litter stays in the box when your cat digs.
- Set up a liner if you use one: If you use a liner, stretch it over the rim and press it into the rim’s grooves to hold it in place. Common mistake: leaving slack in the liner—cats can catch claws and tear it, or the liner can slip down. Pull the liner snug across the bottom before filling with litter.
- Scoop daily and stir litter: Scoop clumps and solids at least once a day. Stir the remaining litter to keep it level and dry. Common mistake: only scooping the top—urine can pool at the bottom and create odor. A daily stir helps you notice changes in urine or stool that may need a vet visit.
- Wash the box weekly: Empty the box, wash with mild soap and warm water, and dry completely before refilling. Avoid harsh chemicals that can irritate cats. Common mistake: skipping the rim and handles—these areas collect spray and dust. Wipe the rim and handles with a pet-safe cleaner each week to keep the antimicrobial surface working effectively.
- Replace litter and monitor use: Fully change clumping litter every 2–4 weeks, or sooner if odor persists. Watch for signs your cat avoids the box, such as eliminating outside it. Common mistake: assuming a high-sided box is always better—some cats dislike the enclosed feel. If your cat stops using the box, try removing the liner or switching to a lower-sided box before assuming a medical issue.
