I used to worry about pee as well and used to carry a bottle but dont anymore. I do believe pee is pee and seen it work in scrapes many times. The exception being if you do drink alot of coffee or if you take certain types of medication then I would advise against it bc if I can smell the difference Im sure a deer can but if your just drinking water or soda or something along those lines I have seen deer tear up a scrape with human pee in it. To each his own on this one I suppose.
