You hear a lot about anglers trying to stay ahead of the game by devising new or better rigs to catch big catfish. Those efforts are all well and good but, sometimes the old tried and true methods are a ticket to success.
Big cats can be pretty wary so it's advisable not to use a sinker if at all possible. Some people are going to ask, "How are you going to cast?" You'd be amazed how much a chunk of liver weighs so, if you're using liver, forget about a sinker. Put something like a 2/0 hook at the end of your line, add some liver and cast away!
Add enough cherry soda (or pop depending of where you're from) to some sugar frosted cornflakes until you get a doughy consistency. Then, you take some dough and start shaping it into a ball. You can even shape a few around hooks to speed things along on your next fishing trip.
If you want to catch more catfish, believe it or not, smearing some peanut butter on your bait or lure may help.
To toughen chicken livers, spread them on a cookie sheet and sprinkle on a mixture of salt and garlic powder. Let them set in the sun for a couple of hours and then, turn them over for a couple more. DON'T try to speed things along by trying this in a microwave! It just cooks the meat.
