Ft. Worth is also nicknamed "Panther City". The name was originally intended as an insult. Back at the turn of the century, a newspaper reported that a panther had been sighted roaming the streets of downtown Ft. Worth. A wag from Dallas picked up on the story and claimed that the panther fell asleep in the middle of the Ft. Worth street since there were so few people there.
When the Ft. Worth city fathers heard about this vile canard, they commissioned a statue of the panther, curled up and sleeping like a kitten. Since then, the name has stuck.
