I used to raise rabiits. Had thirty of them when I sold out. They like to chew on everything!! Give them blocks of wood to chew on to keep their teeth down otherwise they will destroy any part of the cage that is wood that they can get to. They are pretty hardy. They made it throught the winter in NW Iowa with just straw bedding in their huts. It was plywood boxes for shelter. Once I had quite a few they got moved into an old brooder coop. I never had a problem with heat when I was raising them. I raised rex crosses. Had all kinds of colors: calico, white, brown, black, cottontail looking ones. I enjoyed having them. Great pets. Does hurt when you get bit because they have suprisingly sharp teeth. Good luck to ya!!
