Our life is so full of occupations that we have little time to observe animals. If we did, we should see that most of their language is movement. They speak little with one another, mostly they express through their motions. If you call a dog, the dog will at once begin to wag its tail; it will move its whole body to show its joy and affection. If you speak roughly to the dog, its whole body shows that it feels sorry. If the cat is pleased or becomes angry, it shows its feelings at once by its movements.
