Just put a white styrofoam cup over the top of the dog proof trap. I always did that and I caught coons out the wazoo. I also caught some possums and I caught one kitty cat. Both the later when I used mackerel. 3 big fat marshmallows are hard to beat for coons, but they do get funky when they get wet. That's what the cup is for and also to attract the attention of the coon.
If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land. 2 Chronicles 7:14
