The correct answer is option 1. Cats have the ability to immediately adjust their bodies mid-air to land on all four paws, which helps them effectively absorb the impact of the fall. They have a remarkable sense of balance and agility, which allows them to quickly reorient their bodies in such a way that they can land safely.

Option 2, stating that cats have elastic bones, is incorrect. Cats` bones are not elastic, but they do have flexible skeletal structures, which contribute to their ability to twist and align their bodies during a fall.

Option 3, suggesting that cats have thick and elastic skin, is also incorrect. While cats do have a layer of loose skin that allows them to rotate their bodies, it is not specifically thick or elastic.

Option 4 is incorrect as well. Cats are known for their ability to recover from injuries quickly, but they do not get injured equally to other animals. The agility and reflexes of cats significantly reduce the likelihood of serious injury from falls.

In summary, the main reason cats can survive falls from high heights is due to their capability to adjust their bodies in mid-air to land on all four paws and absorb the impact.
