Between my family and i decided to make a roof to floor hutch ( good 6ft high and 2 by 3ft base ) and im wondering on any suggestions to prevent my rabbit from chewing on the wood from inside the hutch once we build it and implement it within my room, and any suggestions to put in the hutch would be great as we are braining storming on what to put in other then a couple layers of places for him to climb, hiding places and a pull out bin at the bottom to clean it out properly.
