At the same time, all acts of behavior of animals are grouped into those that are more related to feeding and those that are related to feeding and reproduction. The dependence between the behavior and psyche of animals as well as with the level of development of their nervous system is shown. Much attention is paid to examples of instinctive reactions. The presence of memory, insight, altruism, aggression, symbolic language of animals, etc. are considered.
