So perhaps a wooden cage is not the best idea for rabbits. I took this video a few days ago. The day before, there was no hole. Guess they had a busy night.
Yep, one day later they were running free in the backyard again. After I took this video, I asked Marshall about finding a way to fix the door/block the hole. But Marshall thought if they were trying that hard to get out, they deserve to run free. And I quote, "You gotta applaud the effort, beady eyes and all."
