Whiskers

Whiskers
To aid with navigation and sensation, cats have dozens of movable whiskers (vibrissae) over their body, especially their faces. These provide information on the width of gaps and on the location of objects in the dark, both by touching objects directly and by sensing air currents; they also trigger protective blink reflexes to protect the eyes from damage.[62]:47

Comparison of cat righting reflexes in gravity vis-à-vis zero gravity
Most breeds of cat have a noted fondness for sitting in high places, or perching. A higher place may serve as a concealed site from which to hunt; domestic cats strike prey by pouncing from a perch such as a tree branch. Another possible explanation is

that height gives the cat a better observation point, allowing it to survey its territory. A cat falling from heights of up to 3 meters (9.8 ft) can right itself and land on its paws.[91] During a fall from a high place, a cat reflexively twists its body and rights itself to land on its feet using its acute sense of balance and flexibility. This reflex is known as the cat righting reflex.[92] A cat always rights itself in the same way during a fall, if it has enough time to do so, which is the case in falls of 90 cm (2 ft 11 in) or more.[93] How cats are able to right themselves when falling has been investigated as the “falling cat problem”.
