Awake at night and asleep all day! Does that sound like someone you know? It is natural for hedgehogs to sleep when it is daylight out, they do not need to be kept near a window even a hedgehog kept in a windowless room will acclimate to the solar changes. It's important to let your hedgehog rest during the day, they will be more playful and excited to interact in the evening time. They also eat and drink mainly at night, so don't worry if they don't eat during daytime hours.
