I once saw a tiger cub, at a zoo, get entangled in some branches. At first it was just a little annoyed, as it was trying to free itself. It was cute to watch and you'd be forgiven for wishing you could've given it a hand. When it couldn't immediately get itself free it began sneering, released its claws and dug into those branches like a chainsaw, pieces of wood flying everywhere.
It was impressive to see how much power, and fury, that cute little thing was packing.
