The “fight or flight response” is an automatic physiological reaction to an event that is perceived as stressful or frightening. The perception of threat activates the sympathetic nervous system and triggers an acute stress response that prepares the body to fight or flee.
Prey animals predictably choose flight over fight, while predators often choose the latter.
But even the peaceful rabbit will respond with a purposely vicious attack when threatened with death.
Beware the cornered rabbit.
