Cee / BuzzFeed In a study, cows were penned for 30 minutes intervals twice, once with a "best friend", and once with a cow it wasn't familiar with.

Baby porcupines have soft quills at birth! Cee / BuzzFeed It doesn't last for a long time though — it hardens very quickly in a few days. 15. Baby elephants suck on their trunks for comfort.

Ōkunoshima, Japan, is an island which is home to a whole bunch of bunnies. Cee / BuzzFeed Nobody knows for sure how all the rabbits got there. 18.
