10 sleeping animals that fill us with positive vibes

Koalas are known to sleep more than 20 hours a day ... and it's not just because they need to ... they just love to sleep a lot. Some animals, such as sheep and goats, fall asleep several times a day. It doesn't matter when or how long our animal friends take a nap, they are still a pleasure to watch.

We think our four-legged buddies want a good rest, which is why we share photos of the cutest sleeping animals.
