The black corrugated road tile stuff would be what i would use for an attractor for both. A 12-24" diameter corrugated pipe turned on its side, maybe 4' long, and then add in pvc sticking out of it. Sort of like a hollow log with limbs sticking upright. Get it to lay flat on bottom with limbs sticking up. Cat will back into the culvert. Crappie and whatever else in the "limbs."
Noodling is big thing on one of the COE lakes nearby. They will either take a 55 gallon poly drum and cut it in half or they make flat boxes that are sort of triangle shaped with an opening about 12"x12"x12" in the front. They'll weight them down with rocks in what will be 4-6 fow at normal pool. Guys dive in and run their arms up in the boxes feeling for fish. Not my speed but they do it.
