Two cats, Babbit and Catstello, are looking for food to alleviate their hunger. Babbit gets a ladder when they see a bird. Catstello is at first reluctant, but manages to go up the ladder. After several failed attempts, Babbit and Catstello construct a makeshift glider and try to swoop down and catch the bird, but the bird reports an air raid, followed by a blackout, and Catstello is shut down. The bird walks by, and just as Babbit and Catstello are about to catch him, the bird screams at the cats to turn out the lights.
