Arrange a veterinary examination for any new or persistent change, then make boxes easy to reach, spacious, clean, and socially safe. The nine methods below combine the Feline Veterinary Medical Association’s December 2024 guidance with Cornell University and AAFP/ISFM behavior recommendations.
Why won’t my cat use the litter box?
House-soiling can result from painful urination, urinary urgency, digestive disease, increased urine production, arthritis or another mobility limitation, cognitive change, litter or box preferences, poor cleaning, difficult access, or conflict with another animal. A cat may still use the box sometimes while a medical problem is developing, so behavior alone cannot identify the cause. Cornell’s overview of house-soiling recommends investigating both medical and behavioral explanations: Cornell Feline Health Center: House Soiling.

Urine marking is also different from ordinary elimination. Marking usually involves small amounts on vertical surfaces, while a cat avoiding the box may leave a larger puddle or stool on a horizontal surface. Both deserve attention, and neither should be interpreted as spite.
When litter-box avoidance is an emergency
Contact a veterinarian promptly if your cat repeatedly strains, makes frequent attempts, cries while urinating, passes blood, or produces very little or no urine. A suspected urethral obstruction is a true emergency requiring immediate veterinary attention; Cornell explains the warning in its lower urinary tract disease guidance: Cornell Feline Health Center: Feline Lower Urinary Tract Disease. Do not wait to see whether a new litter or box fixes these signs.

9 ways to get your cat to use the litter box
1. Rule out a health problem first
Book an examination for a new, repeated, or worsening change in urination or defecation. Your veterinarian may recommend an examination, urine testing, blood work, imaging, stool testing, or other diagnostics based on the history. Tell the clinic when the problem began, how often it happens, whether urine or stool is involved, what the output looks like, and whether appetite, thirst, weight, movement, or vocalization has changed.
Possible contributors include lower urinary tract disease, infection or inflammation, constipation or diarrhea, diabetes or other causes of increased urine production, painful joints, neurologic disease, and age-related cognitive changes. Treating the underlying condition is more important than buying a different box. If the medical workup is reassuring but the problem continues, ask about a veterinary behavior professional.
2. Put every box in a quiet, available location
Choose places that are calm, private, and open around the clock. Avoid laundry machines, furnaces, loud appliances, high-traffic hallways, and locations where a cat can be cornered. Keep boxes away from food and water. A cat should be able to approach, turn around, eliminate, and leave without a person, dog, or another cat suddenly appearing.

In a multi-level home, provide access on every floor so an older, sick, or hurried cat does not have to negotiate stairs each time.
3. Provide enough boxes and separate them
Start with one box per cat plus one extra. For two cats, that means three boxes; for three cats, four boxes. This is a general rule of thumb from the FelineVMA’s December 2024 house-soiling handout, not a guarantee that every household will need exactly that number.
Spread boxes through the home instead of lining them up together. Several boxes side by side may function like one resource if a cat can guard the area. Distribute them so a cat has a realistic alternative when one location is busy or blocked.
4. Choose a roomy, accessible box
Measure your cat from the nose to the base of the tail, then look for a box about 1.5 times that length. The cat needs enough floor space to enter, turn, dig, squat, and cover waste without pressing against the sides. Large or long-bodied cats often outgrow standard trays.

Pick the symptom - the matching free tool is one click away.
Use a low entry for kittens, seniors, or cats with arthritis, weakness, or other mobility limitations. An uncovered box is a sensible option to test because it gives a clear view and two-way escape; some cats prefer the privacy of a cover, while others feel trapped inside one. If you test a covered model, keep an uncovered alternative available rather than removing the cat’s familiar choice abruptly.
5. Let your cat choose the litter
Many cats accept soft, unscented, clumping litter, but no substrate is universal. Preference can involve scent, grain or texture, clumping, and depth. Strong fragrance may be unpleasant to a cat even when it smells clean to people.
Offer different options in separate boxes so you can observe which one your cat uses. Change only one variable at a time where possible: for example, keep the box and location constant while testing unscented versus scented litter. If your cat already uses a particular litter, transition gradually by mixing a small amount of the new product into the old and increasing it over several changes. A sudden switch can create avoidance that looks like a box problem.
6. Keep the box clean on a predictable schedule
Scoop urine clumps and stool at least once a day; some cats need more frequent removal, especially in a small box or a multi-cat home. Wash the empty box with soap and hot water every one to four weeks, depending on use and odor. Rinse and dry it before adding fresh litter.

| Task | Practical schedule | What to avoid |
|---|---|---|
| Remove urine clumps and stool | At least daily | Allowing waste to accumulate |
| Wash the box | Every 1–4 weeks, adjusted for use | Strong chemicals or lingering fragrance |
| Replace damaged or heavily scratched equipment | When odors remain after washing or the surface cannot be cleaned | Assuming deodorizer can replace cleaning |
Avoid ammonia-based cleaners and harsh chemicals. Ammonia can resemble the odor of urine and may encourage repeat soiling or irritate the cat. Use mild soap and hot water for the box itself.
7. Make the route safe in a multi-cat home
A box can be technically present yet functionally inaccessible if another cat blocks the entrance, watches from a nearby hiding place, or waits at the exit. Observe whether your cat hesitates, scans the room, runs away, or is chased after using the box.
Place boxes where no animal can control both the approach and the escape path. Avoid narrow closets with one doorway, dead-end corners, and locations beside a favorite ambush spot. Separate food, water, sleeping areas, scratching posts, and boxes so one cat cannot control all essential resources from one position.
8. Clean previous accident sites promptly
Remove urine or feces as soon as possible and neutralize the odor rather than covering it with perfume. Follow the cleaner’s label, test it on a hidden area first, and keep the cat away until the surface is dry. Wash or replace porous items that continue to smell.
Odor control can reduce the attraction to a previously soiled spot, but it does not diagnose or treat the reason the accident happened. Continue the medical and environmental investigation even after a stain is gone.
9. Respond without punishment and escalate help when needed
Do not yell, hit, rub the cat’s nose in waste, or carry the cat to a box as punishment. These responses increase fear and can make the box or the person associated with it feel unsafe. Clean quietly and record useful details instead: time, location, urine or stool, box used, litter depth, and interactions with other pets.
The AAFP/ISFM guidelines frame house-soiling as a sign that a cat’s medical, physical, social, or environmental needs may not be met. Hazel Carney, DVM, MS, DABVP, co-chair of the AAFP advisory panel, said the guidelines are intended to help practices address these cases “more effectively and confidently.” Read the guidance at AAFP/ISFM Guidelines for Diagnosing and Solving House-soiling Behavior in Cats.
If veterinary treatment, improved access, suitable litter, cleaning, and safer social arrangements do not resolve the problem, request referral to a qualified veterinary behavior professional. Persistent or worsening house-soiling may need a coordinated medical and behavior plan rather than another equipment change.
How to test changes without confusing your cat
Change one major factor at a time when circumstances allow. Keep a simple log for at least several days: which box was used, the litter type and depth, cleaning time, location of any accident, and what happened immediately beforehand. This can reveal patterns such as avoidance only after a noisy appliance runs, only when another cat is nearby, or only with one litter.
- Confirm that urgent urinary signs are absent; seek care immediately if they are present.
- Arrange a veterinary assessment for new or persistent house-soiling.
- Set up accessible boxes in separate locations, including each level of the home.
- Offer a roomy, low-entry or uncovered option when the cat’s body size, age, or mobility suggests it.
- Test litter preferences in separate boxes and transition familiar litter gradually.
- Scoop daily, wash regularly with mild soap and hot water, and neutralize accident odors.
- Review the log with your veterinarian if use does not improve.
Improvement may be gradual, especially when elimination has become associated with pain or fear. Keep successful changes in place while testing alternatives, and avoid removing the only box your cat currently uses.
Quick Recap
Questions to ask your veterinarian
- Could pain, urinary disease, constipation, diarrhea, endocrine disease, mobility limitation, or cognitive change explain this pattern?
- Which tests are appropriate for my cat’s age and symptoms?
- Could the current medication, diet, or litter change affect elimination?
- Would a veterinary behavior referral help if the medical evaluation is normal?
