I am trying to keep my cats enclosed in my backyard, as one really enjoys being outside. I have started to run chicken wire across the top of my six foot wooden privacy fence. I have bent the top of the chicken wire backwards, in towards our yard, and left it flimsy with no support brackets. Should this be enough to prevent escape? Do cats really hate chicken wire like many websites claim? Or am I wasting my time on this method? Thank you ahead of time for replies
