Panther City is another name for Fort Worth

In 1875  Robert E.Cowart, a former Fort Worth resident who practiced law in Dallas, wrote the Dallas Herald that he had "been to a meeting in Fort Worth the other day and things were so quiet I saw a panther asleep on Main Street, undisturbed by the rush of men or the hum of trade."

Fort worth adopted the panther as its mascot and became known as Panther City.  The Fort Worth Police have to this day a panther on the top of their badge.
