Crepuscular animals? What are they?īefore delving into the 'Why?', let's first clarify what a twilight animal. In fact, they are classified as crepuscular animals, meaning they are active during the twilight hours (sunrise and sunset). Given their habits, you'll probably be surprised to learn that hamsters are not, strictly speaking, nocturnal animals.

It's not uncommon (and surprising!) to find that these little creatures sleep during the day, only to become particularly restless after dark. Wondering if hamsters are nocturnal animals? This question may arise in the first few weeks after adopting your first hamster.
