Catching cats on horseshoe is easy. I have been catching as many as I want for years, actually its harder not to catch them.
In the summer during this time of the year just use a bobber with a tail that lays flat. Use a white tube jig and a minnow. Be in 8-12 feet of water and set your jig at 4ft. The cats will find you. When your bobber tail hits 12 noon or straight up then set the hook and have fun.
