Now that cooler weather is setting in I would like to know how the Cats are bitin' on our Pa. waterways. I'm real curious at what temp does the fishing become poor? How deep should we be fishing? I know the Flatheads gather in deep holes for the winter but when does that happen? I've caught Channel Cats ice fishing (every year I alway's seem to catch one) so do they have different cold water habbits than the Flatheads? I wish it wasn't so late in the year, gonna be a long winter. Still time I hope to get a few more Cat's anyhow.
