Start with the right box placement and setup

Most cats will use a litter box if it is in the right place and kept clean. Put the box in a quiet, low-traffic area away from where your cat eats and drinks — cats naturally avoid toileting near their food. A corner of a basement, laundry room, or spare bathroom works well. If you have multiple cats, place boxes on different floors of your home; the rule of thumb is one box per cat, plus one extra.

The box itself matters less than you might think. Standard plastic boxes work fine, but the box must be large enough for your cat to turn around comfortably — at least 1.5 times your cat's body length. An uncovered box is usually better than a covered one, because covered boxes trap odor and make some cats feel trapped. If your cat is older or has mobility issues, choose a box with low sides so entry is straightforward.

Fill the box with 2 to 3 inches of litter. Most cats prefer fine-textured, unscented clumping litter, though preferences vary by individual. If you are switching litter types, do it gradually over a week to avoid startling your cat. Scoop daily and do a full litter change once a week.

Key Takeaways

  • Place the litter box in a quiet area away from food and water, and keep it scrupulously clean — most litter box problems stem from location or cleanliness, not the cat.
  • Use a large, uncovered box with 2 to 3 inches of fine, unscented clumping litter, and scoop daily.
  • If your cat is eliminating outside the box, rule out medical issues first by scheduling a veterinary exam, because urinary tract infections and other conditions often cause this behavior.
  • Confine a new cat to a small room with the litter box for the first few days so it learns the location before exploring the whole house.
  • Never punish a cat for accidents — punishment teaches fear, not box use, and often makes the problem worse.

Confine a new cat to a small space initially

When you first bring a cat home, it does not yet know where the litter box is. Confine it to a single room — a bedroom or bathroom — with the litter box, food, water, and a hiding spot. This forces the cat to discover the box quickly. Most cats will use it within hours.

Keep the cat in this room for at least three to five days, or until you are confident it knows where the box is and is using it regularly. Then gradually open access to the rest of the house, one room at a time. If the cat has an accident in a new area, it may not yet know where the box is in relation to that space — go back to confining it to a smaller area and try again.

Clean accidents thoroughly to remove the scent

If your cat has urinated or defecated outside the box, the smell lingers even after you clean it. Cats are drawn back to spots where they smell their own waste. Use an enzymatic cleaner — one designed specifically for pet urine — rather than regular household cleaners. Enzymatic cleaners break down the uric acid crystals that cause the smell to persist.

Soak the affected area generously with the enzymatic cleaner and let it sit for the time the product recommends, usually 10 to 15 minutes. Do not use ammonia-based cleaners, because ammonia smells like urine to cats and may actually encourage them to use that spot again. After cleaning, block access to that area for a few days if possible, so your cat cannot return to it out of habit.

Rule out medical problems with a veterinary exam

Before assuming your cat has a behavioral problem, take it to a veterinarian. Urinary tract infections, kidney disease, diabetes, and intestinal parasites all cause cats to eliminate outside the box. A cat with a medical issue is not being stubborn — it is in distress and needs treatment.

Tell your veterinarian exactly what is happening: whether the cat is urinating or defecating outside the box, where it is going, and how long this has been occurring. Bring a urine sample if possible. Once medical causes are ruled out, you can focus on environmental and behavioral solutions with confidence.

Add more boxes if you have multiple cats

Cats are territorial, and one cat may prevent another from reaching the box. If you have two cats and one box, the subordinate cat may avoid the box to stay away from the dominant one. Add a second box in a different location — ideally on a different floor or in a different room. If the problem persists, add a third box.

Place boxes far enough apart that a cat using one box cannot see or easily reach another cat at a different box. This gives each cat a sense of privacy and reduces conflict. If one cat is blocking access to all boxes, you may need to feed them separately or use baby gates to create zones where each cat can reach a box without encountering the other.

Avoid punishment and never rub the cat's nose in accidents

Punishing a cat for an accident teaches it to fear you, not to use the box. A cat that has been punished may hide to eliminate, making the problem harder to solve. It may also become anxious around the litter box itself, associating the box with punishment rather than relief.

If you catch your cat in the act, calmly pick it up and place it in the litter box. Do not yell or hit. If you find an accident after the fact, straightforward clean it thoroughly with an enzymatic cleaner and move on. Your job is to make the box more attractive and accessible, not to make the cat afraid.

Try a different litter type if your cat refuses the current one

Some cats are picky about litter texture or smell. If your cat is avoiding the box, try a different litter. Set up two boxes side by side — one with your current litter and one with a new type — and see which one your cat uses. Common alternatives include non-clumping litter, crystal litter, pine litter, or paper-based litter.

If your cat has always used one type and suddenly stops, a change in the brand or formula may be the cause. Check the bag to see if the manufacturer changed the product. If so, switch back to the previous version or try a different brand altogether. Some cats are sensitive enough to notice small changes in their litter.

Frequently Asked Questions

Why is my cat peeing outside the box but pooping in it?

This often signals a medical issue, particularly a urinary tract infection or kidney problem. Schedule a veterinary exam when ready. If medical causes are ruled out, the cat may be anxious about the box itself — try adding a second box in a different location and may support both are very clean.

My cat uses the box sometimes but not always. What am I doing wrong?

Inconsistent use usually means the box is not clean enough, not in the right location, or the cat has a medical issue. Scoop twice daily instead of once, and make sure the box is in a truly quiet, accessible spot. If the cat is older, add a box with lower sides. A veterinary exam will rule out health problems.

Can I train a cat to use the toilet instead of a litter box?

Some cats can be trained to use the toilet with special training kits, but this is advanced and not necessary. Most cats prefer a traditional litter box, and toilet training can be stressful. Stick with a proper litter box setup unless you have a specific reason to pursue toilet training.

How often should I change the litter completely?

Scoop clumps daily and do a full litter change once a week. If you have multiple cats or notice odor building up, change it twice a week. Some litters last longer than others — follow the manufacturer's recommendation, but weekly changes are standard for most households.

What if my cat suddenly stops using the box after months of good behavior?

A sudden change almost always signals a medical problem or a major environmental change. Schedule a veterinary exam first. If the cat is healthy, check whether the box location has changed, whether the litter brand changed, or whether something stressful happened in the home — a new pet, a move, or a change in routine.
