How Should You Set Up and Maintain Your Cat’s Litter Box?

Use the right box, litter, and cleaning routine to help your cat stay comfortable and prevent house-soiling.

A clean, accessible litter box supports healthy elimination habits. The best setup gives your cat privacy, a firm surface, and enough space while keeping odors and tracked litter under control.

Choose the right box and location

Select a large, uncovered box with a low side or step for easy entry. Many cats prefer one box per cat, plus one extra, especially in multi-cat homes. Place it in a quiet area away from loud appliances, drafts, food, and heavy traffic. Keep at least one box indoors if your cat goes outside, since weather can reduce outdoor access. For kittens, elderly cats, or cats with mobility problems, provide a shallow box with stable flooring and easy access.

Select suitable litter

Choose unscented, fine-grain, dust-free clumping litter for most cats. Avoid strongly perfumed products, which can irritate sensitive airways. Offer a second litter type, such as a different clumping texture or non-clumping litter, in a separate box so your cat can express a preference. Do not switch litter suddenly during a household transition; transition gradually over about a week and watch for straining or avoidance.

Helpful tip: Keep a litter box away from noisy washing machines and place a washable mat nearby to catch stray litter. A covered box may reduce odors, but an uncovered box is easier to monitor and clean. Never use a box that smells strongly of cleaners.

Clean on a consistent schedule

Remove feces and urine clumps daily, including the litter around them. Scoop without disturbing the rest of the litter unnecessarily. At least once a week, empty the entire box, wash it with mild soap and water, rinse thoroughly, and dry before refilling. Replace litter when it becomes damp, discolored, or develops an odor. Never use bleach, ammonia, or harsh chemical cleaners, because cats may dislike or be harmed by the fumes.

Weekly deep-clean routine

Move safely: Transfer your cat to a secure room or another clean area before handling used litter.
Remove waste: Wear gloves, bag waste, and wash reusable tools as directed.
Wash the box: Use warm water and mild, unscented soap, then rinse until no residue remains.
Dry and refill: Let the box dry fully, add a moderate layer of fresh litter, and return your cat.
Check closely: Observe the next elimination for pain, changes in size, or repeated attempts.

Recognize problems and when to call a veterinarian

Do not punish a cat for inappropriate elimination. Clean affected areas with an enzyme-based cleaner and rule out litter-box causes first. Sudden changes, frequent small amounts of urine, straining, crying, blood, weight loss, or hiding may indicate urinary or gastrointestinal illness.

See a veterinarian promptly: A male or female cat making frequent, urgent attempts to urinate with little or no output, especially with vomiting or lethargy, may have a life-threatening urinary obstruction. Seek urgent veterinary care rather than waiting for routine box changes.
