Someone asked how the fox got inside the wire. Here's a pic that I think shows him going through the mesh. I don't think there is any other way in, unless he crawled underneath somehow where the javelina was digging. Next time I'm down there, I'll look more closely. This pic shows him with his head inside, but not sure if his body followed or not.
It appears that he's half in and half out on this frame, with at least one paw inside.
