At night cats generally move shallower to feed, I favor flats very near deep water, say flats of 6-10 feet of water near 20 -60 feet nearby. Outside and Inside bends in river channel, these bends have stronger current , and concentrate bait fish, and the game fish that are after them. Baits basically if it stinks in works lol, chicken liver, cut shad, bluegill, chicken boneless in general, Live bluegill, or suckers, or shad, also good, and you may even nail monster bass or striper on the live baits as well as monster cats.
