Jumping Gigi

Gigi loves to jump up onto high shelves and survey us from above. She can jump more than about six feet and make it look easy. According to Wikipedia, most breeds of cat have a noted fondness for settling in high places, or perching. Animal behaviorists have posited a number of explanations, the most common being that height gives the cat a better observation point, allowing it to survey its "territory" and become aware of activities of people and other pets in the area. In the wild, a higher place may serve as a concealed site from which to hunt; domestic cats are known to strike prey by pouncing from such a perch as a tree branch, as does a leopard. (Not true for Gigi, her 'attack' pose is definitely crouched low on the ground.) Height can also give cats a sense of security and prestige. According to Wikipedia, during a fall from a high place, a cat can reflexively twist its body and right itself using its acute sense of balance and flexibility. This is known as the cat's "righting reflex". It always rights itself in the same way, provided it has the time to do so, during a fall. The height required for this to occur in most cats (safely) is around 3 feet (90 cm). To achieve this, cats probably relax their ventral muscles, "flattening" their bodies to some extent and creating more resistance to air. However, cats' fondness for high spaces can dangerously test the righting reflex. The American Society for the Prevention of Cruelty to Animals warns owners to safeguard the more dangerous perches in their homes, to avoid "high-rise syndrome", where an overconfident cat falls from an extreme height.
