Actually, the porcupine and the hedgehog are quite different animals. And it occurs to me that the above pictures don't really show the true nature of the hedgehog, which is one of the cutest animals known to the land:
Hedgehog quills are about 2 cm long; porkys are more like 10-12 or so. Porkys are smarter and more aggressive; hedgehogs are more defensive, and just roll up into a ball when threatened. Porkys also lack the cute naked face and underbelly,
The real controversy comes over the killing of such a cute animal, always a provocative course of action.
Don't kill me!
