ditto on the trap.
I had coons, possum, fox and hawk/owl around my place.
added netting to the top of the pen.. that stopped the hawk / owl.
then I put in hardware wire around the base of the pens, burried 6" deep, and then put a fence board around the bottom perimeter of the pen.
a single errant animal can then be trapped.
I have loose dogs and it didn't seem to scare away the large male coons.
