My three year old hedgie refuses to run on his new wheel. I got him comfortable on it, and he didn't seem to scared or nervous about it when I put it in his cage but he refuses to actually run on it. I got him the Carolina Storm Bucket Wheel because his old one was to loud at night and he lives in my room with me. So I thought this would help because he loves to run but now I'm worried because he wont, and putting the old one back in is not an option. Can someone please give me some advice?
