Don't tell me they can't smell human piss. I can smell it so they can. Don't tell me they can't tell the difference. Maybe they don't know it is human, but they do know it smells different than anything else.
I'm looking and haven't found it yet, but that is exactly what I'm telling you. They can't tell the difference. I read an article that discussed the subject and there was talk of amino acids, etc. and that after a very short amount of time after ground contact (a couple hours at the most) there was no way to tell what animal (human, deer, pig, bear, etc.) had urinated on that spot. Yes they can smell the urine, but they can't tell the difference between human urine and deer urine.
