My understanding is Cougars are ambush predators,so an attack is likely(if at all) from above & behind or just from behind,pushing one to the ground,& going straight for the back of the neck,of which is the spine & just so happens to be our most vulnerable area for a mortal wound.In theory,it would take one bite to drop a human,Cougars reflexes are 5x our own if not more!Statistics prove nothing in the Great Outdoors,Murphy makes darn sure of that!Personally,I choose to be Equipped to Survive,Afterall that's the whole point,Isn't it?
