Here's a breakdown of their sleep patterns:
* During the day: They sleep for 12-18 hours, often curled up in a ball for warmth and protection.
* During the winter: They hibernate, which can last for 4-5 months, depending on the climate. During hibernation, their body temperature drops, and their breathing and heart rate slow down significantly.
So, in short, hedgehogs spend a good portion of their lives sleeping!
