Other senses are now shutting down as it can no longer make sense of sights and sounds. In a state of confusion it is spared much pain as the sense of touch becomes shut down but for the response to a few extreme insults to its body as it is being eaten. The animal goes into a trance, withdraws from the effort of resisting, falls into coma, then dies. In the first level of stress the herd pulls together and begins moving to another area for grazing, repeating a usual route. Parents nurse their young or lead them to whatever food is available.
Sexual activity increases.
When sufficient food is still not found and hunger increases, the second level of stress is reached. Animals still stay close to their offspring but the herd disperses over a much wider area and connections to the group diminish as the herd explores untried territory seeking food. Some animals lose the herd entirely. The animals change directions more often without as much reason as they will find themselves grazing territory already grazed without success. Animals are more sensitive and fights break out between members of the group.
