I let her mess with the new version and test it to the best of her evil brooder hacking abilities, under supervision. At one point, she was chewing on the wire, and jumping from the window sill onto it. She eventually gave up in frustration. This cat can open doors, so I can't guarantee shutting her out of a room.
In her defense, she's a cat.
In retrospect, I was pretty stupid to use window screening in the first version. I knew she has ripped out window screens before.
