Why is my cat pooping outside the litter box? Don’t treat it as spite. Start by checking the litter box, recent changes around the home and anything unusual about your cat’s elimination.
Note where the poop lands and when it started, then clean the spot fully, reset the box and check the setup. If your cat strains, you see blood, the stool changes markedly, or the change came on suddenly, talk to your vet first.
Want the bigger picture? Our guide on why your cat is not using the litter box covers every cause.
Where the Poop Lands
The spot doesn’t tell you the cause, but it gives you something to check.
Right next to the box: your cat is getting close, so look hard at the box itself. Our guide on cat pooping next to the litter box covers this one in full.
Poop right beside the box is a reason to look closely at the box itself.
On soft things like rugs, beds or laundry: the surface doesn’t tell you why it happened. Check whether anything changed around the home and whether the box is clean, roomy and easy to reach.
Random spots around the house: check box location and access, and pay attention to the stool itself. A marked stool change, straining or urgency-like behavior is something to discuss with your vet.
The same spot every time: clean that area especially thoroughly and check for any leftover odor. Repeated use of one spot doesn’t tell you the cause by itself.
What to Check
The box.
- Is it big enough to turn around in? Our best extra large litter box guide covers sizing.
- Is the entry easy to step over? See our low entry litter box picks.
- Is it clean? Some cats skip a box that looks fine to you.
- Did the litter change? A new texture or scent is worth noting.
The home. Note recent changes such as new people or pets, moving, rearranged furniture or new noise near the box.
Other cats. In a multi-cat home, one cat can block or watch the box. Add boxes in separate spots. Our guide on how many litter boxes per cat explains how many.
Interruptions. Notice whether a loud noise, another pet or another interruption happened while your cat was using the box.
What to Do First
Step 1: Watch the stool and your cat. Note any marked stool change, straining, crying, blood or other sudden change from your cat’s normal pattern. Those are reasons to contact your vet.
Step 2: Clean the spot fully. Use an enzyme cleaner like Hepper Bio-Enzyme Pet Stain and Odor Eliminator on every spot your cat has used. Follow the label for how long to leave it, then let it dry.
Treat every spot your cat has used, following the cleaner’s label.
Step 3: Reset the box. Empty the box, wash it with mild soap and water, dry it and refill it with litter your cat already uses reliably.
Step 4: Change one thing at a time. If you change the box, litter and location all at once, you won’t know what worked.
When to Call the Vet
Talk to your vet if the change is sudden, your cat strains or cries in the box, you see blood, the stool changes markedly, or the behavior continues despite reasonable setup changes.
Frequently Asked Questions
Why is my cat pooping outside the box but still peeing in it?
Using the box for urine but not stool doesn’t point to one cause. Check the box size, cleanliness, litter and location, and pay attention to any change in the stool or in how your cat acts while trying to go.
Watch how your cat approaches and uses the box.
Should I punish my cat?
No. Punishment adds stress and can make your cat avoid the box more. Fix the setup instead.
Will changing the litter help?
It can, if the current litter is new to your cat or your cat avoids it. Go back to what worked before, or offer the new one in a second box next to the old one. Our guide on how to transition cat litter covers it.
Does cleaning the spot really matter?
Yes. Use an enzyme cleaner on every spot your cat has used and follow the label.
