OM, that's horrible. I'm so sorry. I feel it. My daughter had two pet rabbits that we thought we'd dog proofed the cage - wooden frame, welded wire. Each time they ripped through the welded wire like it was a pancake. In a leash law county, the owner said, well they're used to running and I'm not going to pen them up now. Hello!? They killed a child's pet for no reason. If they ate it, I would feel better, but they weren't hungry, just "having some fun with the pack." I did overkill on my chicken house, it looks a bit cobbled together, but it's not going to be broken into unless there's a bear.
