1. The Hedgehog:
When a baby hedgehog (called either a hoglet or piglet) enters the world, it’s a tiny, blind ball of spikes waiting to be unleashed.
That’s because when it’s born, sharp protuberances-in-waiting are tucked just underneath the skin. Within a few hours of exiting its mother womb and as it’s surrounded by upwards of six siblings, a hoglet’s signature quills will start to make their debut.
It’s a slow start to what will become the hoglet’s key defense mechanism as an adult, as 150 slightly dulled quills break through the skin and begin increasing in numbers until the hedgehog has 8,500 of them.
Hoglets are blind for the first month of their life, but that doesn’t stop them from wrestling with their brothers and sisters over a prime spot at mom’s milk bar. White as snow when they are born, the hoglets will also begin taking on the physical appearance of an adult hedgehog with the darkening of their quills.
These little spiked bundles of cuteness will stay with mom for anywhere from six to thirteen weeks, at which point they bid a fond farewell to their family unit and move out into the waiting world.
