One day accidentally I discover a kind of non metallic mesh that it is so dense and strong that is impossible also for a cat to damage it. I found it in a store that sells raw materials for shoe makers. They explained to me that it is a special mesh that is used to reinforce soft parts of the shoes or to make sandals from it. They didn't give me some special name for it, but I think it will be easy for you to make a search in local stores. Believe me it is worth the effort.
