I had about 5-6lb cat slam my lure on the surface a couple months ago and although it was nowhere near the size of your fish It proved to be a very hot fish and put a better fight then I have got from cats twice it's size in the past. After that I had a whole new respect for those fish. I had lost another on the topwater a couple weeks after that which ended up falling off but it also proved to be an above average cat. I wouldn't bother soaking bait to catch them but if they hit the topwater like that all the time I would soon turn in to a catfish hunter.
