When we first moved in, the cat pee smell was noticable, but as the years went by, it became less and less until you could no longer smell it.
I went into her apartment Sunday afternoon to retrieve some of my things and was hit in the face with a blast of cat pee smell.
Who knew that cat pee was so potent that it could still stink up a place after 20 years? Yuck!
I hope the landlord finally replaces the carpets.
