Animal hypnosis also termed tonic immobility or reflex immobility is a behavioural state in which the animal is both immobilized and more or less unresponsive to most of physiological stimuli. The effect has been observed in many different species including birds and mammals. It occurs spontaneously in the wildlife as for the so-called feigning death, playing possum, fascination etc. It is considered as a survival strategy. It is likely due to a large release of endorphins by the hypophysis explaining that tonic immobility is associated to analgesia and drowsiness. It can be obtained experimentally using various types of physical stimuli (kitten becomes quiet when their mother grasps them by the neck), tools (as clip for cats, nose twitch for horse etc.).
