Least weasel

This finicky, wise little weasel is the smallest species of the Carnivora order, making it the tiniest true carnivore in the world.

Weighing in at under 50 grams, It might be hard to imagine something so small being such a clever hunter, but the lesser weasel is the worst nightmare of any small rodent it encounters.

They are also known for having a "small person complex", often exhibiting a much bigger, more ferocious personality than their small size might suggest.
