Trees cannot grow at high altitude, because of cold temperature or lack of available moisture. [83]: 51 The lack of trees causes an ecotone, or boundary, that is obvious to observers.

During a fall from a high place, a cat can reflexively twist its body and right itself using its acute sense of balance and its flexibility. [8] [9] This is known as the cat's "righting reflex". The minimum height required for this to occur in most cats (safely) would be around 90 cm (3.0 ft).
