i've only been fishing cats for about a year total, but i've tried just about every bait out there in that time. as far as channels go, the best and biggest bites i've gotten have come on any cut baitfish i've taken out of the spots where i fish the channels. mostly, that's consisted of mooneye and bluegill. i've heard that catfish have stored in their memory the smell and taste of every meal they've ever had. that would mean that we're most likely to get them to bite on what's familiar to them. (that would also mean that they're a lot smarter than predatory fish, trout, bass, etc., that hit things based on motion and appearance as well.) that especially goes for the big cats that have the longest and most extensive catalog of smells and tastes. it's just a theory, but it seems like it works. cats are my number one fish now, and probably 'til i die, so i'd be interested in knowing if anyone else has heard this theory or tested this out.
