Your telling me an animal would rather eat than to breed? What is the animals reward on a scent? Don't have to think about that.A scrape line is visited every day by that animal till the rut is over and he has bred.During most hunting season for deer anyway,the rut is in that genral time zone.During late season the rut is over in most areas where hunting is pemited.Now,Deer are curious animals.If you use reg deer urine and spread it around in the area you are hunting,Deer will come investigate other deer in the area before they go and feed.Try it,it does work all the time.There is no diffrence in it.They both lure deer in one way or another.
