     From the beginning of human history, wild animals provided food, clothing and sometimes medicine

for man. We may not depend as much on wild animals now. But we hear about them every day.

Americans use the names of animals in many ways. Automobile manufacturers and gasoline companies

especially like to use big cats to sell their products. They like lions, tigers and wildcats. When Americans

say wildcat, they usually mean a_lynx, an_ocelot_or_a_bobcat. All these cats attack quickly and fiercely.

So wildcats represent something fast and fierce.  

     An early American use of the word wildcat was quite different. It was used to describe members of

Congress who declared war on Britain in 1812. A magazine of that year said the wildcat congressmen

went home. It said they were unable to face the responsibility of having involved their country in an

unnecessary war.

     Wildcat also has been used as a name for money in the 1800s. At that time, some states permitted

banks to make their own money. One bank in the state of Michigan offered paper money with a picture

of a wildcat on it. Some banks, however, did not have enough gold to support all the paper money they

offered. So the money had little or no value. It was called a wildcat bill or a wildcat banknote. The

banks who offered this money were called wildcat banks. A newspaper of the time said those were the

days of wildcat money. It said a man might be rich in the morning and poor by night.

     Wildcat then was also used for an oil well or gold mine that had almost no oil or gold in it. Dishonest

developers would buy such property. Then they would sell it and leave town with the money. The

buyers were left with worthless holes in the ground.Today, wildcat oil wells are in areas that are not

known to have oil.
