Start with the right box placement and setup
A cat will use the litter box reliably when it is straightforward to find and feels safe. Place the box in a quiet, low-traffic area away from where your cat eats and drinks — cats naturally avoid toileting near their food. The box should be in a spot your cat can reach without passing through doors that are often closed, and ideally in a room where your cat spends time.
Use an unscented, fine-grained litter at first. Clumping litter works well because it lets you remove waste daily, keeping the box clean and odor-free. Avoid heavily perfumed litters, which can deter cats. Fill the box 2 to 3 inches deep — deep enough for your cat to dig and cover waste, but not so deep that kittens or older cats struggle to move around inside.
If you have multiple cats, the rule is one box per cat plus one extra. A cat that feels crowded or has to wait will find another spot in your home. Keep all boxes in different locations so each cat has options.
Key Takeaways
- Place the litter box in a quiet, accessible location away from food and water bowls, where your cat can reach it without navigating closed doors.
- Use unscented, fine-grained clumping litter and keep it 2 to 3 inches deep, scooping waste out daily to maintain cleanliness.
- Introduce a new cat or kitten to the box by placing them inside it when they first arrive, and again after meals and naps.
- If your cat has an accident outside the box, clean the spot thoroughly with enzymatic cleaner to remove the scent and prevent repeat use.
- Watch for signs of medical problems — sudden avoidance of the box can signal a urinary tract infection or other health issue that needs veterinary attention.
Introduce your cat to the box on arrival
When a new cat or kitten first enters your home, place them directly into the litter box. This teaches them where it is and signals that this is the right place to go. Leave them there for a minute or two, then let them explore the rest of their space.
For the first few days, place your cat in the box again after meals, after naps, and before bedtime — these are the times cats naturally need to eliminate. Praise and pet your cat when it uses the box. If your cat goes in the box on its own, reward it when ready with a calm voice and gentle attention. Avoid loud praise or sudden movements, which can startle a cat away from the box.
Kittens typically learn from their mother, so a kitten separated early may need more reminders. Adult cats adopted from shelters usually know what a litter box is for; they may just need to find yours. Be patient — most cats understand the concept within a few days to a week.
Clean the box daily and replace litter regularly
Scoop out clumps and solid waste at least once a day. A dirty box is the most common reason a cat stops using it. If the box smells bad or looks full, your cat will look elsewhere. Daily scooping takes two minutes and prevents almost all litter box problems.
Replace all the litter and wash the box itself once a week. Use hot water and mild dish soap — avoid strong chemical cleaners, which can leave odors that deter cats. Dry the box completely before adding fresh litter. If the box is stained or cracked, replace it; cats notice and may avoid a box that feels unclean.
If you use a covered box or litter box furniture, make sure it is straightforward to clean. Some cats dislike covered boxes because they trap odor and feel confining. If your cat is avoiding the box, try removing the cover or switching to an open box to see if that helps.
Handle accidents outside the box correctly
If your cat urinates or defecates outside the box, the first step is to clean the spot thoroughly. Use an enzymatic cleaner — a product that breaks down the urine or feces at a chemical level — rather than regular household cleaners. Cats can smell traces that humans cannot, and if the scent remains, your cat will return to that spot. Enzymatic cleaners are sold at pet stores and online under names like Nature's Miracle, Rocco & Roxie, or Meow Mix Enzymatic Cleaner.
After cleaning, block your cat's access to that area for a few days if possible. Place a litter box in or near the spot where the accident happened, then gradually move it back to its original location over a week or two. This helps redirect your cat's instinct back to the box.
Do not punish your cat for accidents. Yelling, rubbing your cat's nose in the mess, or any form of physical punishment will only make your cat afraid of you and more likely to hide when eliminating. Cats do not connect punishment to their action the way dogs do.
Rule out medical problems
If a cat that has been reliably using the box suddenly stops, a health issue is often the cause. Urinary tract infections, kidney disease, diabetes, and digestive problems can all make a cat avoid the box. An older cat may have arthritis that makes climbing into a high-sided box painful. A cat with diarrhea may not make it to the box in time.
Schedule a veterinary checkup if your cat's litter box habits change suddenly. Bring a sample of any urine or stool if you can, as this helps the veterinarian diagnose the problem faster. Do not assume your cat is being stubborn — a behavior change is usually your cat's way of telling you something is wrong.
Once any medical issue is treated, your cat will usually return to normal litter box use. If the problem persists after a clean bill of health, then focus on the box setup and cleanliness.
Adjust the box for older cats and special situations
Older cats or cats with mobility issues may need a box with lower sides so they can step in and out without strain. Look for boxes labeled "senior" or "low-entry," or use a storage container with one side cut down. Make sure the box is on the same floor where your cat spends most of its time — a cat with arthritis will not climb stairs to reach the bathroom.
If your cat is recovering from surgery or illness, place a litter box in the room where it is resting. A weakened cat may not have the energy to walk far. Once your cat is fully recovered, you can move the box back to its regular location.
For a cat that is learning to use the box for the first time as an adult — perhaps a feral cat or one from a neglectful home — be extra patient. Place multiple boxes around your home so the cat has several chances to find one. Reward any use of the box, even if it is not perfect. Some cats take weeks to become reliable, but most do learn.
Frequently Asked Questions
How long does it take to litter train a cat?
Most kittens and adult cats understand the concept within a few days to a week. Some cats are reliable within days; others take two to three weeks. If your cat has not used the box after three weeks, or if a previously trained cat suddenly stops, talk to your veterinarian to rule out medical problems.
Should I use a covered litter box?
Covered boxes appeal to owners because they hide odor and mess, but many cats dislike them. Covered boxes trap odor, limit escape routes, and can feel confining. If your cat is avoiding the box, try removing the cover or switching to an open box. You can always add a cover later if your cat is comfortable.
What if my cat uses the box sometimes but not always?
Inconsistent use usually means the box is dirty, in an inconvenient location, or your cat has a medical problem. Scoop daily, make sure the box is straightforward to reach, and schedule a veterinary checkup. If you have multiple cats, add another box — a cat may avoid a shared box if it feels crowded.
Can I move the litter box to a different room?
Yes, but move it gradually. Shift the box a few feet every day over a week or two, rather than moving it across the house overnight. A cat may not find the box in its new location and have an accident. Once the box is in its final spot, keep it there — cats learn where it is and expect it to stay put.
Is it normal for a cat to kick litter outside the box?
Yes. Cats dig and cover their waste, and some litter naturally scatters. Use a litter mat under and around the box to catch stray litter, or place the box in a corner where kicked litter lands against a wall. A larger box or one with higher sides can also reduce scatter.
