Couple of baits to try
Squid (remember to remove the "back bone".
Really smelly cheese moulded into a ball.
Chicken leg (yes i am serious)
Or live baits (Eel are a favourite) & as Esox said fish it close to the surface.
Remember in cat fishin you don't get screamers you get "steamers" cos striking into a cat on its primary run is like trying to stop a steam train with cotton
