Only two animals have entered the human household otherwise than as prisoners and become domesticated by other means than those of enforced servilities: the dog and the cat. Two things they have in common, namely, that both belong to the order of carnivores and both serve man in their capacity of hunters.
In all other characteristics, above all in the manner of their association with man, they are as different as the night from the day. There is no domestic animal which has so rapidly altered its whole way of living, indeed its whole sphere of interests, that has become domestic in so true a sense as the dog; and there is no animal that, in the course of its century old association with man, has altered so little as the cat. There is some truth in the assertion that the cat, with the exception of a few luxury breeds, such as Angoras, Persians and Siamese, is no domestic animal but a completely wild being. Maintaining its full independence it has taken up its abode in the houses and outhouses of man, for the simple reason that there are more mice they’ re than elsewhere: The whole charm of the dog lies in the depth of the friendship and the strength of the spiritual ties with which he has bound himself to man, but the appeal of the cat lies in the very fact that she has formed no close bond with him, that she has’ the uncompromising independence of a tiger or a leopard while she is hunting in his stables and barns; that she still remain mysterious and remote when she is rubbing herself gently against the legs of her mistress or purring contentedly in front of the fire.
The purring cat is, for me, a symbol of the heart side and the hidden security, which it stands for. I should no more like to be without a cat, in my home than to be without the dog that trots behind me in field or street, Since my earliest youth I have always had dogs and cats about me. Business like friends have advised me to write a dog book and a cat book separately, because dog lovers often dislike cats and cat lovers frequently abhor dogs. But I consider, it the finest test of genuine love and understanding of animals if a person has sympathies for both these creatures, and can appreciate in each its own special virtue.

Many superstitious people are afraid of black cats. They believe that black cats have a strange power. If a black cat crosses their path, they think they will have bad luck.
Black cats haven’t always had such a bad reputation. Long ago, the Egyptians thought that black cats were holy animals. They even worshipped them. Pasht was an Egyptian goddess who had a woman’s body and a cat’s head. Because the Egyptians had so much respect for black cats, they often buried the sacred creatures with great ceremony. Mummies of cats have often been found in ancient cemetery ruins. To keep the cats company after they died, mice were sometimes buried beside them.
Feelings about black cats have always been strong. People have thought they were either very good or very bad. The people of Europe, in the Middle Ages, believed black cats were the evil friends of witches and the Devil. Witches were said to have the power to change themselves into black cats. People believed that you could not tell whether a black cat was just a cat, or whether it was a witch disguising herself as she plotted some evil scheme. The brain of a black cat was thought to be a main ingredient in witch’s brew.
Unlike their ancestors of the Middle Ages, Englishmen today consider black cats to be good luck charms. Fishermen’s wives often keep a black cat around so that their husbands will be protected when they are out at sea.
The Egyptian goddess Pasht had a ______.

A:woman’s head and a cat’s body B:woman’s head and a lion’s body C:cat’s head and a man’s body D:woman’s body and a cat’s head
