My female cat decides that she likes to pee on the couches. It seems as if she only does it when my mom comes home from being away for an extended period of time, this time about 4 days. Its not the couches since we have already had to replace them. We are thinking that we might need to get rid of the cat. Does anyone know why she does this and how we can get her to stop…oh and cat training spray does not work.
