I have a biologist friend who did a lot of research on mock scrapes. What the guys have suggested above has been demonstrated in a study. This guy set out trail cameras and used different scents and than did a statistical analysis of scrape visits. As I recall, there was some negative reaction to fox urine. Human urine and deer urine showed no statistical differences in visits.
I would highly recommend using your own urine. First, you won't find anything fresher. Second, most natural deer urine sold is collected from captive deer. CWD prevalence in captive deer is high compared to wild deer in most areas. Science has shown prions can be present in collected urine. Our state recently outlawed the use of natural deer urine (synthetic is ok). Why take a chance of spreading the disease when you got the right stuff!
Thanks,

a lot of misinformation here regarding urine and CWD, heres a snippet from a study on this very issue-
It appears this maybe more politically motivated than science based.
CWD prions cannot be detected in
urine without amplification. Urine
from even clinically sick deer must
be highly concentrated, in order to
produce enough prions to even test.
In the study commonly referenced,
the urine was concentrated, 10 times
greater than normal, and then injected
directly into the brains of test sub-
jects. Even in these experimental con-
ditions that were extremely unnatural,
only 1 in 10 subjects proved infected.

Let’s be honest, deer in the wild don’t get urine injected into their brains.
