Cats are generally very calm, always bent on doing their own thing and usually take the path of least resistance, and move around doing what they want, but these creatures turn voracious and attack back at you if you corner them on 3 sides.
Moral of the story: Don’t push the seemingly calm ones just about too much that they’re left with nothing but to attack back on you.
Alternative moral of the story: Most of the people, like cats, behave very relaxed until they are left with no other alternative. Often when boats are burned, and no other alternative is left, people perform their best.
