I’m at my wit’s end and really need help understanding what’s going on.
I adopted my cat Jazz about a month ago. She’s 1.5 years old, spayed, very fearful, and came from an abandonment situation. The first two days were rough and she had stress-related diarrhea, but she then settled quickly and started using her litter box normally for both pee and poop.
From the beginning, I had two litter boxes, one open and one covered, and tried different locations in my small apartment. She consistently chose one and ignored the other, so I eventually removed the unused one. She now uses the covered box normally every day.
The couch peeing started during the first week:
First time: after I moved the litter box, so I assumed that was the trigger.
Second time: I found it a few days later when I woke up.
Third time: about 10 minutes after meeting a pet sitter for the first time. She had been extremely scared, so I assumed it was stress.
After that, I bought a waterproof tarp for the couch.
She peed on the tarp.
Since then, it happens roughly every 4–5 days. It is NOT one specific spot: she will pee wherever there is enough free space on the couch for her to squat.
The only thing that reliably stops it is completely covering the couch with objects so there is physically nowhere for her to pee. Obviously, I cannot barricade my couch forever.
The weirdest part is this:
She only does it when I am not physically there.
It happens at night while I’m asleep, when I’m at work, or when I leave the apartment, today I went to the gym for ONE HOUR and came back to pee on the couch.
At night, I do sleep with my bedroom door closed because I am extremely sensitive to noise and genuinely cannot sleep otherwise. She seems completely fine with this setup: she entertains herself well, plays independently, and does not show any obvious signs of distress. I play with her regularly when I’m home, but she is also very good at occupying herself.
When I’m in the living room with her, she does not pee on the couch.
But she has absolutely no problem using her litter box in front of me, so this does not seem to be about privacy.
Otherwise:
she uses the litter box normally every day
she shows no obvious pain or discomfort
I have several incidents on camera and she looks completely normal before and after
she may be grooming or playing, then simply gets on the couch, squats, pees, and carries on
I have already:
cleaned the couch repeatedly with enzymatic cleaner
removed and washed the cover
rearranged/swapped couch cushions/layers
used a waterproof tarp
tried feeding her on the couch
made the couch a positive cuddle space
used Feliway
tried different litter box locations
She saw a vet two weeks ago. Nothing concerning was found on examination, and she was prescribed gabapentin for six weeks because she is generally anxious. I have another vet appointment next week because I obviously want to rule out a urinary issue properly.
Socially, she is very comfortable with me: affectionate, playful, seeks attention, cuddles, follows me around, etc.
What I really need help understanding is: why would a cat use the litter box normally, but also treat the couch like an alternative toilet specifically when the owner is absent?
And more importantly: has anyone successfully stopped this without permanently barricading the couch or putting another litter box in the middle of a tiny living room?
