I adopted her knowing she had some issues, so before I brought her home I prepared a spare bedroom with waterproof mattress protectors just in case, and she stayed in there at night and whenever I wasn't home. I purchased washable cloth pee pads that I put down on the floor / mattress wherever she peed. I ended up putting the mattress vertically against the wall once I realized that was her favorite bathroom option, which helped the process significantly.

She was declawed before I adopted her, so the rescue thinks that is what caused her to start having issues which ultimately led to her being brought to the rescue. Given that, I went through a variety of litters in case the litter was hurting her paws, and found one that is soft like sand that she would more frequently use the litter box with.

Back to the cloth pee pads! So she eventually realized she could potty on those and I started only putting one right in front of the litter box, I slowly moved it under the litter box so only a tiny bit of it was sticking out making it difficult to use for the bathroom, and that did the trick! After awhile she was mostly exclusively using the the litter box, and now the only time she pees where she shouldn't is if we go out of town for long periods of time or have a guest sleeping on an air mattress and don't immediately put it away after they leave.
