I know outdoor rabbits shouldn't be bought in a warm house during the winter to live, unless done before the cold weather and their warm coat has come, and indoor rabbits shouldn't be put out to live in the cold winter as they won't have a proper winter coat. My question is, what if rabbits have free access to indoor and outdoors day and night, so they can choose where to go, will it affect their health if they go in and out all day? I think that wild rabbits would do this, go from burrow and outside and back into the burrow?
