Cathey graduated from St. Frederick High School and the University of Louisiana at Monroe. He is a member of the First Baptist Church of West Monroe. He is a board member for the YMCA, the Kiwanis International, and the Warrior Foundation.

In 2015, Cathey was an unsuccessful Republican candidate for the state Senate in District 35. He lost to former state Representative James R. Fannin of Jackson Parish, who in turn was unseated in 2019 by state Representative Jay Morris. When Cathey switched to District 33 to succeed the term-limited Republican Michael Arthur Walsworth (born 1956), he faced an intra-party challenge from Wade Bishop, a West Monroe businessman. Cathy prevailed in the primary, 16,658 votes (52 percent) to Bishop's 15,407 (48 percent). Walsworth instead ran unsuccessfully for the position of Ouachita Parish Clerk of Court having been defeated by an Independent.
