i dont worry with a pee bottle, ive seen too many deer go right by where ive peed and if they notice it they sure dont give an indication. My personal theory is that so many people pee in the woods just in the course of a year (campers, hikers, hunters not worried about smells like squirrel or rabbit, etc) that it just doesnt register to them. The only place i think id use one would be if i was seriously far back in the woods dealing with deer who may not have much or any human contact.
