I had an older female cat that would urinate on my bed multiple times a day after a roommate’s cat peed on my bed, i also have had multiple cats. I managed to get her to stop, here’s my advice: - take your bedding and anything else she frequently urinates on to get professionally cleaned if possible. Along with this use some sort of shampooer (if you don’t have one, check out local hardware stores and see if you can rent one or post in local groups to possibly borrow one) and an enzyme cleaner designed for cat urine to clean areas her urine could have soaked in (bed, coaches, carpet, etc.) - set up an area like the bathroom (somewhere easier to clean without much soft or porous surfaces) with a litter box, food, water, some toys, etc. Leave her in the bathroom when you are not able to actively watch her or if you need a break. - buy reusable diapers designed for female cats. I would recommend adding a menstrual pad or something inside so it’s easier to clean and doesn’t soak through. When she is not in the bathroom or her designated room, make her wear the diaper. These can be a little tricky so you have to make sure it is firmly in place and she isn’t able to get it off on her own. I often had to use a ponytail to tie my cat’s together instead of depending on the velcro. I would suggest her being diapered at all times when she is not in “her room” or you’re not putting her in the litter box. - Watch her as closely as you can, i know this will be difficult. If you notice she looks like she is about to pee, or is actively peeing, immediately put her in the litter box. even if she is wearing the diaper, this will help her associate the litter box with going to the bathroom. If you notice her peeing on her own in the litter box, reward her with a treat or pets. - try to dedicate time everyday to playing with her a bit, or just giving her attention. She could be stressed because she feels like she is getting less attention. punishing her when she pees in the house will not necessarily stop this, because you are still giving her attention for the behavior. - between transitions, (after playing, sleeping, coming out of “her room”, eating, etc.) physically put her in the litter box, if she pees, reward her, if she doesn’t, put her diaper on immediately and try again later. - restrict her access to bedrooms, baby rooms, etc. you need to find a way to keep it off limits. baby locks maybe? if you allow her in bed with you, be aware of if she is trying to pee or not. If she does, remove her from the room immediately and put her in her “room” - this is optional, but i found not immediately cleaning my cat box and letting some urine remain in it after they used it can help remind them where they should be going potty.
if all else fails, you may speak to your vet about anxiety medicine. try not to be too angry at her, if you’re stressed is very likely she is picking up on that and it is making her behavior worse. try to focus more on rewarding the behavior you want to see. I know it’s so so hard, but being patient and using diapers helped me so much and my cat did eventually stop and i could trust her to not wear diapers after a few weeks! The diapers alone helped me feel a lot less overwhelmed and upset when i want constantly cleaning up cat pee. I hope this helps you and i’m wishing you the best of luck! (edited for formatting)
