12+ Adorable Pictures Of Hedgehogs To Celebrate National Hedgehog Day

Today, February 2, is not just any other day – it is, actually, a very special day.

You might have heard of some of the most famous hedgehogs, like Sonic The Hedgehog, or Beatrix Potter’s character, the hedgehog washerwoman Mrs. Tiggy-Winkles, but hedgehogs everywhere deserve to be honored this day, if only for how cute they are.
