Man’s relation with animals is very old. They can be traced back to the beginning of civilization. Basically man is also an animal, but a rational and wise animal. Man is the best creation and measure of all things. However, his kinship with animals is well established. Darwin believed that man has evolved from monkeys. Thus, they are our ancestors.The friendship between man and animals is more reliable and lasting. The pet animals respond better to our care, love and friendship. Man’s friendship with man may not last long, but it is of permanent nature with the domesticated and pet animals. Animals, birds and such other creatures are never ungrateful. Once friends, they are always friends. They will never turn hostile or enemies came what may. They are constant, loyal and faithful till the last. They do not know betrayal, deceit or foul play.
