Im not sure if this is just one of those things hedgehogs do for no apparent reason or if I should be worried. I have have two CHEs that keep the cage around 74-76 degrees. The first day I got him he slept in front of his wheel (uncovered) and then the next two days he slept in his igloo and today he slept under is wheel? Also, he's taking multiple naps during the night, this is normal I'm guessing? Since he's only 6 weeks old?
