Just curious here could just be me, but we lose a TON of big game animals to wolves and cougars. Has anyone ever put any thought into the fact that just a wolf or a cats presence stresses the big game animals tremendously? So in the fall and winter months when breeding is at it's yearly peak and deer and elk are at their most vulnerable, wouldn't it make sense that just the stress of these two apex predators alone could be enough to stress out the does and cows to the point that their heat cycles are interrupted, thus causing them to go unbred?
