His run is on the fenceline. The original angle of the hole wasn't toward the fence, but im sure he has to have turned one way or another by now. I did mention it to my neighbor, in case he pops up in his backyard. Other than that, my idea is to pop a metal dog cage on top of his escape holes when he opens them.
There's a farm in my area where there's a domestic rabbit warren; super cool.
One night Hopper didn't come in to his hutch for the night. I sure was happy he made it through. Since then, he's come in all nights (about 4 since then). Maybe it will be ok for him to stay outside when he's got his tunnel all fixed up, but he's still pulling a lot of dirt out every day. It's so cute- he pushes the loose dirt around with his front feet or his nose. He's spreading it out.
His (wire-covered) run is inside of my fenced garden, and next to the neighbor's fenced back yard. We do have predators, though.
