in my case also a substantial structure the wire was simply pulled open. Like the coon took it's front paws and just spread the wire apart.Creating a coon sized hole to climb thru. Flimsy crap, just meant to keep chickens in.
I thought chicken wire was good enough until the grapes were taken out around me and a momma coon needed to eat. She did not open the wire at a seam, she ripped it open from the middle and this wire was still silver, so it wasn't old. She also was medium size compared to some I have seen. It's like having a car alarm. It works until someone really wants your car.
