In 1923, Brigham Young University selected the cougar as its mascot. The cougar was suggested because it is native to Utah and it exemplified the traits that he hoped athletes competing for Brigham Young University would have. These traits included strength, agility, grace, quickness, and beauty. In 1925, two cougar cubs (Cleo and Tarbo) were brought to campus to serve as mascots. The cougar kittens were kept on the south side of Temple Hill until 1929 when they managed to break out of their cage, sending out a cry from the faculty, “The cougars are out!” This incident produced the lyrical chorus of the BYU Fight Song in 1932 - "Rise and shout, the Cougars are out." Live cougars were later replaced by Cosmo the Cougar. On October 15, 1953, Cosmo the Cougar made his first appearance in front of BYU fans, flying into LaVell Edwards Stadium on a parachute.
