Down south here, we tend to use raw chicken livers or hearts for them catfishes. Your local grocery store may have them but if they don't check with the meat dept. manager for them, maybe he can supply you with them. Also, catawba worms below a cork, and even your local baitfish/minnows will catch them.
The best stinkbait I ever used was called "Cat Attack" but I have not seen it around here in many, many years now. Gone by the wayside I suppose?? Any of the stinkbaits will work.
