The construction of the shoulder joints permits the cat to turn its foreleg in almost any direction. Because the vertebrae of the spinal column are held together by muscles rather than by ligaments, as in humans, the cat can elongate or contract its back, curve it upward, or oscillate it along the vertebral line. Unlike the dog and horse, the cat walks or runs by moving first the front and back legs on one side, then the front and back legs on the other side only the camel and the giraffe move in a similar way.
