Passage 2

When one sees a lazy, contented cat stretched out asleep in front of the fire, it is hard to believe that she is the first cousin to the tiger. If you want proof of the cat's relationship to the tiger, watch her stalking sparrows in the roadway. She creeps nearer and nearer her prey, taking advantage of any shelter, while her eyes blaze with excitement, and muscle stands out rigid and ready for the fatal spring.Again, look at the infinite patience of the cat watching a mouse-hole. It sticks to its post for days together, until the poor mouse is caught.

The cat is one of the most friendly animals. As far back as history goes she has always been a household pet. In Egypt cats were worshipped.

Hundreds of instances might be given of the cleverness of cats. Cats will learn to open latched doors and ring bells. They will pick up odd friendships with dogs, and have been known to make friends with rats, pigeons, chickens, frogs, and other strangers.

There is a well-known story in France of a cat who, after sitting in its sick mistress' room until she died, visited the grave and was found lying dead there, apparently of grief.

Cats are very fond of their young, and watch over them just as human beings do over their babies. An interesting story of a cat's bravery is the following:

Some kittens belonging to a farmer's pet cat were playing in the yard, when a sparrow-hawk swooped down and carried one off. Without an instant's pause, the cat flew off to the forest, where she knew the hawk's nest was. She came to the tree and scrambled up it, and in the large nest at the top she found her kitten unharmed, nestling down among the young hawks. She seized it in her mouth and carried it home. When the hawk appeared again the cat was on the watch, caught the thief and rolled it about on the ground until the hawk made its escape and let the kittens alone.

Domestic cats are of many colors and sizes, and are found all over the world. In America, people look upon the cat as a symbol of luck. Cats are excellent hunters, and arc much used to keep rats and mice away from houses. They are active at night in their habits, like the rest of their tribe, only instead of roaming the jungles, they parade the roofs of houses, and keep people awake with their sad cries.
