I don’t know what a cat Mark smells like but I just read that it’s a very pungent pee smell? I halve this lady that I work with that wears the same pants almost everyday. Like she’ll wear them for a week straight or alternate between two pants. When she comes in my office and sits down I can smell a really strong pee odor ugh and when she opens her legs it’s even worse. She’s going through menapause and is always hot so I imagine all the sweat and pee and vagina secretions just sitting at the crotch of her pants. I mean her hair will smell like shampoo so I’m guessing she washes but even if ur clean ur clothing will hold ur odor until you wash it especially if ur wearing it everyday.
