As a huge animal lover, when I saw this videos headline, I had to click 'play'!

Rabbits are known to multiply quickly and there's proof of that right here!  During World War 2, eight bunnies were left on the island Okunoshima, Japan, where they were used to test mustard gas.  (Totally not cool!  I'll save my animal testing rant for another day...)

So, as you'd imagine, 8 bunnies soon turned into a whole bunch, and now this island is known as Rabbit Island!

Here's an adorable video of a young girl being followed by the rabbits, and they gather around her as she gives them food.  It's adorable.
