Cats are not only nimble, agile, but extremely flexible. They can literally bend over backwards. The reason that cats are capable of arching their back so tall is because their spine consists of 60 vertebrae as opposed to 34 in humans.
Cats have great balance too. They maneuver their tail to position their body in a way that they can land on their feet after falling from a height.
Cats can combine these two wonderful skills and perform various stunts that often surprise us. The video below presents you a kitten with excellent contortion skills.
