I don't know about predators but as soon as I got my run covered on top with chicken wire my outside cat climbed a tree next to the run and walked across the top to see how she could get in. I thanked her for doing the predator test. My run is 20 x 20 and it totally surrounds the coop. I made it 7' tall to walk under and put 1x2's across the top to support the chicken wire. It works for me because we have no snow here, I don't know how it would hold the weight of snow. Sorry, I have no pics.
