Clean the litter box daily by scooping clumps and waste

The fastest way to keep odor down and your cat comfortable is to scoop out clumped urine and solid waste once a day, ideally at the same time each day. Use a slotted scoop — the kind with holes that let clean litter fall back into the box while trapping waste. Push the scoop to the bottom of the box at a slight angle, lift slowly, and let the litter drain through before dumping the waste into a trash bag or disposal bin.

Scoop in the morning or evening, whichever fits your routine. Cats often use the box right after waking or before bed, so you may find more waste at those times. If you have multiple cats, scoop twice daily to prevent one cat from avoiding a dirty box and urinating elsewhere in your home.

Dispose of scooped waste in a sealed trash can or a dedicated litter disposal system. Do not flush cat litter down the toilet — even "flushable" litters can cause plumbing problems and harm water treatment systems.

Key Takeaways

  • Scoop clumped litter and waste once daily using a slotted scoop, pushing to the bottom and lifting slowly to let clean litter drain back into the box.
  • Replace all litter and wash the box with hot water and unscented dish soap every one to two weeks, depending on how many cats you have.
  • Add fresh litter to the depth the manufacturer recommends — usually 2 to 3 inches — after scooping or after a full wash.
  • Never use bleach, ammonia, or scented cleaners, as the smell can make cats avoid the box or cause respiratory irritation.
  • Keep the box in a quiet, low-traffic area away from food and water bowls, and away from noisy appliances that might startle your cat mid-use.

Wash the entire box every one to two weeks

Once a week (or twice a week if you have three or more cats), empty all the litter into a trash bag and wash the box itself. Lift the box carefully — litter dust will rise — and pour the contents into your trash. Rinse the box under hot running water to remove dust and stuck-on urine crystals.

Fill the box with a few inches of hot water and add a squirt of unscented dish soap. Use a brush or cloth to scrub the bottom and sides, paying special attention to corners where urine pools. Rinse thoroughly with hot water until no soap remains — cats are sensitive to scent, and soap residue can discourage them from using the box.

Dry the box with a towel or let it air-dry for a few minutes before adding fresh litter. If the box is cracked, stained, or smells even after washing, replace it. Plastic boxes absorb odor over time and cannot be fully cleaned.

Add the right depth of fresh litter after cleaning

Pour fresh litter into the clean, dry box to the depth recommended on the bag — usually 2 to 3 inches. This depth lets cats dig and bury waste naturally while giving you enough material to scoop without hitting the bottom of the box constantly. Too little litter makes the box uncomfortable; too much wastes litter and makes scooping harder.

If you are switching litter brands or types, mix the new litter with some of the old litter for the first few days. Cats notice changes in texture and smell, and a gradual switch prevents them from rejecting the box. Once your cat is used to the new litter, you can use it exclusively.

Avoid cleaners that will make your cat avoid the box

Never use bleach, ammonia, vinegar, or scented cleaners on the litter box. Bleach and ammonia create toxic fumes, especially in enclosed spaces, and can harm your cat's lungs. Vinegar and strong-smelling cleaners may seem natural, but cats dislike the smell and may stop using the box to avoid it.

Stick to hot water and plain, unscented dish soap. If you want to disinfect, hot water alone kills most bacteria and viruses. For stubborn odor, soak the box in hot water for 15 minutes before scrubbing, or replace the box if washing no longer removes the smell.

Position the box away from noise and food

Place the litter box in a quiet, low-traffic area of your home — a bathroom corner, laundry room, or spare bedroom works well. Keep it at least a few feet away from your cat's food and water bowls. Cats naturally avoid eliminating near where they eat, so a box too close to food may be rejected.

Avoid placing the box near loud appliances like washing machines or furnaces. A sudden noise while your cat is using the box can startle them and create a negative association. If you have multiple cats, place boxes in different rooms so each cat has access without having to pass through another cat's territory.

Handle litter dust and odor buildup

If dust rises when you scoop or pour litter, switch to a low-dust or dust-free litter brand. Dust irritates both your lungs and your cat's, and some cats with respiratory sensitivity will avoid dusty boxes. Paper-based, pine, or crystal litters typically produce less dust than clay.

If odor builds up between scoopings, you may be scooping too shallowly or the box is too small for your cat. Urine that sits in the litter longer produces more ammonia smell. Scoop deeper, reaching the bottom of the box, and consider upgrading to a larger box if your cat is large or if you have multiple cats sharing one box. One box per cat, plus one extra, is the standard guideline.

Frequently Asked Questions

How often should I completely replace the litter?

Replace all litter once a week if you have one cat, and twice a week if you have two or more. If you scoop daily and the box smells fresh, you can stretch it to every 10 days with one cat. The moment you notice ammonia smell or see wet clumps breaking apart, it is time for a full change.

Can I use baking soda to reduce odor?

A light sprinkle of baking soda on top of fresh litter can help absorb odor between scoopings, but do not mix it throughout the litter or use it as a substitute for scooping. Some cats dislike the texture change. If odor is a persistent problem, daily scooping and weekly washing will work better than any additive.

What should I do if my cat stops using the box?

A cat avoiding the litter box usually means the box is dirty, too small, in a noisy location, or the litter type has changed. Start by scooping more frequently and washing the box thoroughly with hot water and unscented soap. If the problem continues, try a second box in a different location, or switch back to the litter brand your cat preferred.

Is it safe to use a litter box liner?

Liners can make cleanup easier, but many cats dislike the plastic texture under their paws and will avoid the box or dig at the liner instead of the litter. If you use one, choose a thick, durable liner and watch whether your cat's behavior changes. If they seem uncomfortable, remove it and scoop without a liner.

How do I dispose of litter safely?

Seal scooped waste in a small trash bag and place it in your regular household trash. Do not flush any litter, even brands labeled flushable, as it can clog pipes and harm municipal water systems. If you want a more contained option, use a dedicated litter disposal system that seals waste in cartridges.
