ghirahim Asked: although male users are more likely to mark urine than females it is not unknown for a female user to scent mark too. often a sexually frustrated female user will mark to advertise her availability. a dominant female will also mark. a common deterrent is a pepsi can with coins in it, or an empty pepsi bottle with pebbles in it. tape it shut and shake it only once when you notice your tumblr followers making signs that they are going to pee. yell "NO PEE" and be consistent. it may take a while.
