I don't target catfish but do catch quite a few in ponds here in southern Iowa on bead heads like pheasant tails. This summer I stumbled onto using a beadhead pink squirrel and the cats really seem to like it. I experminted a little and came up with something a little better. Use a 10 or 12 hook and tie on bead chain eyes then tie a pheasant tail only with a pink antron thorax. Tie the tail fibers off in front of the beads and leave a short collar of the butt ends. I fish it under a float on about a 7 foot leader with 4lb tippet. Most of the takes come as it is falling and so far has taken bluegills, crappies, bass, catfish, and a grass carp. Lots of fun!
