The University of Arizona participates in the NCAA's Division I-A in the Pacific Ten Conference. Arizona joined the PAC-10 in 1978 along with Arizona State University, bringing the conference to its current 10 teams. The school colors are cardinal red and navy blue, and the official fight song is "Fight! Wildcats! Fight!", though "Bear Down, Arizona!" is more commonly used and "Bear Down" is the university's motto.
The Wildcats name derived from a 1914 football game with then California champions Occidental College, where the L.A. Times asserted that Arizona "showed the fight of wildcats."
The University mascots are anthropomorphized wildcats named Wilbur and Wilma. The identities of Wilbur and Wilma are kept secret through the year as the mascots appear only in costume. In 1986, Wilbur and Wilma, a longtime couple, were married. Together, Wilbur and Wilma appear along with the cheerleading squad at most Wildcat sporting events.
