Is a cat the most flexible animal in the world?

Because cats are originally from the wild which means their body need to be flexible to run faster during hunting or from the enemy's, to climb things and to jump back down from things which is why cats love to go hunting and climbing.

A Cats Spine is Made of 30 Vertebrae, excluding 14- 28 in the tail... Their legs absorb Shock on Impact because of these different verts.
