Rabbits and digging go together like dogs and barking; it’s just something that many rabbits do. Some rabbits dig more than others. Why do rabbits dig? You can’t really expect an answer from your bunny. But you can make an educated guess.

Your rabbit “talks” to you via body language, not just vocalization. Understanding what your quiet companion is saying with body language just takes some observation.
