In addition to what everyone has already said, I have had some hedgehogs that chose on their own to be active during the day. However, they were still active at night.
I know it won't be this way for everyone, but for me, after some time, I got used to the sounds they made in their cages at night. I lived with it for years. After moving in with my boyfriend, and him getting allergies (to the point where he literally couldn't breathe), we moved the hedgehogs to another room. I gotta tell you, after so many years of hearing hedgehogs scuffling around doing hedgehog things, I found myself unable to sleep because it was so quiet in the room. It felt weird that I couldn't hear my hedgehogs and I was very uncomfortable with this idea of not having them in the bedroom.
