If they are not met frustration, fear and boredom, giving way to psychological escapism, prevails. They want to be free - free to eat, roam, choose a territory, choose a mate or companion, free to explore and investigate, using all their senses. And in all this, they wish to make their own decisions concerning their own lives on a daily basis. To the extent that we can accommodate their quest and purpose in life, we can cohabitate with them. There are many principles of survival, but they all point behavior to one goal - respect.
Respect is the essential concept between any two life-forms.
Respect is the demonstration of the mixture of love and fear that keeps one from taking advantage of another, it is a standard that all morality is based upon and the basis for all interpersonal contact. It is also the mortar between the bricks of a relationship and a need we all desire for personal achievement and fulfillment. Respect is the evidence of worth. These are the factors affecting animal behavior. They are well designed, complicated and yet simple.
