Never got the displeasure of hearing one in the woods but I am sure it will cause uncontrolled bodily function like constricted hair follicles and unconstricted sphinter muscle
But I did care for a guys "cat yard" and he had several each of most of what we call "exotic cats" and man they got a voice you will never forget! Now picture a female in heat and 2 male cougars yellin at each other all night from their cages... And her sounding like she is dieing!
