We live in Ohio and have found that Little Friskies cat food with any sort of fish in it works well. We get the little cans,open them and dribble the juice to make a scent path to the live trap. Set the can of the solids in the trap. We occasionally catch a cat or an opossum with this bait. The cats are usually of the feral sort and need to receive the same final treatment as the raccoon. Never caught a skunk (god forbid) but I suppose it is a possibility,
Raccoons are really wary. Don't compromise your set with a lot of other scents, Most importantly human or canine. Those two scents are major warnings to 'coon and it may deter them from bait or prey. But remember they can recognize that the scents in a much used area are a normal pattern that they can deal with. Human or dog scent in a random place is alarming to them.
We always dealt with the major attacks (that is when the baby coon start to travel with their mother, the wheat is harvested and deprives them of a major food source, water starts to become scarce, all usually around the 4the of July) by poisoning them wholesale. One year we lost birds for three days and trapped 9 coon in that time. Got serious the third night and set a lot of poison. Pitchforked 27 out of the yard an onto the trailer the next morning, Have no idea if any made it into surrounding cover before they died.
I have become more tolerant of raccoons as I age.Used to be I would drive into the ditch to run over one of the dam things, Now it has to be a mother and her litter before I go to the ditch after them.
