Explain how is a cat able to land on its feet after a fall taking advantage of the principle of conservation of angular momentum?

Answer:

                While falling, a cat stretches its body along with the tail so that its moment of inertia (I) increases. As no external torque is acting, \[\text{L}=l\omega \]= constant. As I increases, \[\omega \] decreases and it lands gently on its feet.
