hello, I just got a new one year old hedgehog and I want to make sure he gets enough exercise, I saw at petco a run-about ball and I was wondering if it's safe for him to run around in? I know that it's important that his feet can't get caught but other then that is there a problem? I would really like this to be an option because my house is not what I would call hedgehog proof and this way he would be allowed to explore my house without getting into something he shouldn't.
