FANTASTIC FELINES

The Friday File: We know falling cats seem to always land feet first, but why? Physicists and cat-falling researchers find that the feline spine is extremely flexible in the upper thoracic vertebrae, but stiffer and heavier in the lower lumbar vertebrae. Cats first turn their front legs, and then their lower legs. The upper vertebrae can rotate an astounding 360 degrees. They also appear to have a right-side (paw) bias.
