And this video shows why you want to keep a close eye or a leash on a bunny in your yard even if it is fenced. I have heard of bunnies digging their way under fences and disappearing completely. Although I would love to let our little Shadow go and get a whole lot of digging out of his system, our area is very rural with lots of wild animals and predatory birds. So our bunnies stay inside house rabbit only.
