I like using cut bait for cats. Skipjack, shiners, sunfish ect. For smaller bodies of water it's hard to beat livers or a big gob of night crawlers. I like to find spots near a deep drop off or a hump of some sort. This time of the year I mostly catfish at night in shallower water fishing on bottom. Here's a pic of a 30lb blue I caught off of skipjack. Don't worry it was released!
