Tettleton, who completed 20 of 35 passes, moved into Ohio's all-time, top five for career passing completions.
Marshall (1-2) had a chance to rally, driving from its own 25 to the Ohio 27, but Jelani Woseley intercepted a Cato pass to seal the win.
Cato led Marshall with 432 yards and three touchdowns on 44-of-65 passing.
The win marks the Bobcats' first 2-0 start on the road since 1976 and second consecutive season with a 3-0 start.
