Our 11 week old African Hedgehog loves her wheel. I have a large, solid wheel in her cage. I cannot believe how fast and how long she runs! Her little legs look like a blur! She must travel a couple (or more?) miles nightly. Does anyone know if hedgies travel long distances in the wild? or is this some reaction to being confined? Would it be harmful if she does not have the wheel everyday? I'm wondering if switching out the wheel once or twice a week for different toys would change the 'scenery' and prevent 'boredom'? She seems to have a good temperament. She only huffs- quills up when you first approach her cage, and then her quills flatten out when she realizes it is us. Sometimes she likes to be held, and sometimes she likes to explore. We love her!
