Girls, Smelly sister?

I need help my older sister who is thirty came to live with me and she smells like cat piss (we dont have cats). She takes a bath everyday sometimes two per day but the smell remains. She has already made the room I let in her stay in smell so bad like cat pee. She is starting to make my house smell like cat pee. I hate staying home now and when I do it makes me have anxiety. I feel like it's not my home anymore. She is very sensitive and argumentive when any issue arrives. Please I need advice on how I can approach her about this situation.
