  • Urinating to litterbox walls

    Posted by Ana Martins on January 1, 2026 at 4:58 pm

    Hi! I have 3 cats, 2 male, 1 female, all spayed and 2 extra large litter boxes, well maintained as I work from home. There were never litter box issues and they all kind of use the same litter box at times. However since I got my youngest cat, the middle male cat often pees to the walls of the litter instead of normally and quite often. However it is not any health issue and he does not do this all the time. He is very vocal and loves attention and I notice that these incidents happen when he calls and I don’t answer immediately. Other times he just chases my female cat aggressively. I understand he may feel threatened or tense even though I give him as much attention as before. Any advice?

    Hi Ana,

    Thank you for reaching out.

    Can you please confirm whether your male cat squats, lifts his tail, or sprays while he’s peeing inside the litter tray? Feel free to take a video and share it here.

    How long ago did the youngest cat join the family, and did the peeing behavior start a few weeks or months after her arrival?

    Thank you

    Sounds a little like our household. We have 2 that pee high so we slip a paper towel in-between the bottom and top lip of the boxes so it absorbs most of it and then we change it out when it’s wet. I know it’s bothersome but be glad he’s not peeing on your house walls. I hope he doesn’t start that since it’s hard to break. Goodluck

    I adopted my 7 yr old male cat 3 years ago and he does not squat when he pees nor does he bury it. I have witnessed him lifting his tail and aiming at the litterbox walls. Sometimes he pees with his front paws out of the box and rear paws in it. This makes me so angry because the smell is strong, I have to use pee pads for the floor around the box. I now have his litter box in an oversized storage tote to control the mess. Been to the vet. No health issues.

    How, or what can I do to help improve this behavior? Please help!

      Hi TJ

      Are you able to confirm if your cat is desexed and whether he sprays or elevates his bum when he pees?

      Spraying is a behavior in which a cat backs up to a vertical surface, stands upright with a quivering tail raised high, and then directs a concentrated stream of strong-smelling urine backwards. It’s different from typical squatting urination.

      Male cats typically spray due to stress, anxiety, territorial threats, dissatisfaction with the litter tray and medical issues. It’s essential to have your vet perform a urinalysis and, based on its results, possibly a urine culture.

      Meanwhile, you can create a spraying station as shown below, or replace your litter tray with a round litter box pictured here.

      I hope that helps.
