112.IS THE PORPOISE A MAMMAL?
It is hard to believe that the porpoise is not a fish, but a mammal. Yet it is just as much a mammal as the cow in the fields. Porpoises, dolphins and whales form the order called “Cetacea” of the group of aquatic mammals.
Actually, dolphins belong to the whale family and porpoises are a variety of dolphins. All these animals may be given the general name of whales, or cetaceans.
111.HOW LONG HAVE CATS BEEN PETS?
When most people say “Cat,” they are thinking of the small, domestic cat. But the cat family is really quite an amazing one, and includes leopards, lions, tigers, and jaguars!
All cats, large or small, have the same general proportions of body, and the same food habits. All cats are meat eaters and kill their own food. Depending on the size of the cat, this food ranges from small mice and birds up to large zebras, deer, antelope, and cattle.
110.DOES A SHEEP GROW WOOL EVERY YEAR?
The wool that grows on a sheep is like the hair that grows on your head. It grows the same way and is the protective covering of the sheep against cold weather.
Once a year, usually in the spring when warm weather is ahead and the sheep no longer needs its “protection,” the sheep are given a haircut and all the wool is sheared off. It is usually full of burrs, thorns, and natural oil which is called “lanolin.” It comes off almost whole, like a hide, and is then rolled up and tied with wool twine.
