Pretty soon I will be moving into my new apartment in which I will be sleeping in the basement of the apartment along with keeping my hedgehog in my room. Obviously, during the winter it will probably become extremely cold in the basement. I would keep her upstairs but my roomate would not approce. I am normally very stingy with heating my place because of how high the utilities bill can become. I was wondering, what would be the best way to keep my hedgehog comfortable while at the same tine not running up my electric bill?
