A cat peeing on the bed is hard on you and your mattress. The fix has two parts: clean the bed so nothing is left behind, then look for what changed.
Strip and wash the bedding, treat the affected mattress area with an enzyme cleaner according to the label, let it dry completely, and keep your cat off the bed for now. Then check the litter box and recent changes at home. If your cat strains, makes repeated trips with little or no urine, or seems distressed, call your vet right away.
For the full list of reasons cats pee outside the box, see our guide on why your cat is peeing outside the litter box.
Clean the Bed First
1. Strip and wash everything. Take off sheets, blankets and the mattress cover. Wash them following the care label, and skip heavy fragrances.
Wash all the bedding, following each item’s care label.
2. Treat the mattress, not just the bedding. Blot up any fresh moisture first, then use an enzyme cleaner such as Simple Green Cat Stain and Odor Remover on the affected area. Spot-test first, follow the label for application, and let the mattress dry completely before remaking the bed.
Treat the affected mattress area following the cleaner’s label, then let it dry fully.
3. Hold off on heat. Follow the cleaner’s directions, and avoid steam or hot air on the spot unless the label says it’s fine.
Keep Your Cat Off the Bed for Now
Close the bedroom door while you work on the cause. If you can’t, cover the bed with something waterproof during the day. This reduces access to the same spot while the mattress dries and you check the setup.
Check the Litter Box
- Is it clean?
- Is it easy to reach, day and night?
- Did the litter, box or location change recently?
- In a multi-cat home, are there enough boxes in separate spots? Our guide on how many litter boxes per cat explains it.
Look at What Changed
Note recent changes such as new people or pets, moving, rearranged furniture, a new schedule or new noise near the box. A bed is soft and carries your scent, and those are features of the spot worth knowing. They don’t tell you why your cat chose it.
Note when it happens and what changed at home around that time.
When it happens is worth noting too. If it happens at night, check whether the box stays easy to reach and reasonably clean then too.
When to Call the Vet
Repeated attempts to pee with little or no urine, especially with straining or distress, need urgent veterinary attention.
Also talk to your vet if the change is sudden, your cat cries in the box, you see blood in the urine, or the behavior continues despite reasonable setup changes.
Frequently Asked Questions
Why is my cat peeing on my bed instead of the litter box?
It doesn’t point to one cause. Check the box, recent changes at home, and your cat for the vet signs above. Our peeing outside the litter box guide walks through each possibility.
Will my cat keep peeing on the bed once it starts?
It can recur. Thorough cleaning and temporarily limiting access address the spot itself, while the litter box and vet checks address the wider problem.
Should I punish my cat?
No. Punishment adds stress and can make litter box problems worse.
My cat pees on the bed but still uses the box. What does that mean?
Using the litter box at other times doesn’t point to one cause. Check the existing box setup, and consider offering a second box in another location or a different litter in a separate box so your cat has another option.
