Hi, I have a 15 year old female cat, she has been spayed since she was a year and a half old. She was always an outdoor cat until we moved to a bigger city and I have kept her inside for the past three months. I have found that she has been urinating against the wall on my carpet in the basement where her litterbox is kept. SHe has always been such a clean cat all her years and she is very healthy. Is it possible that she is homesick? She lived all her years in the one area, or is it more of a chance that she just wants outside and is being spiteful? Please any advice would help, her litter box is always clean so there is really no excuse for this, there must be something I can do?
