Yes, all predators are opportunistic feeders, preying on whatever is most available, but Catfish are very efficient predators also, they readily seek out the same live prey as bass. I've caught many catfish on lures, including plastic worms. The reason we don't catch more catfish on lures is that they are more active at night. I use to do a lot of catfishing with live and cut-bait. I've caught many large channels and blues on live shad and big flatheads on bluegill, including several c&r line-class world records, all at night.
