We are building a run, and plan on using welded wire (2" x 4") for the fencing. We do plan on burying it to keep out dogs and other larger predators. We live in the city (although you wouldn't know it, as we are on about an acre of land) so there aren't any many predators to worry about, at least that I am aware of. So will I need to run hardware fabric around the bottom as well? Or do you think we should be ok? Any advice would be much appreciated! Thanks!
