What does a cat’s airplane ears expression mean?

A cat’s airplane ears can express several emotions. First, a cat often makes airplane ears when nervous or afraid, such as when startled. Second, airplane ears can signal an impending attack; before striking, a cat usually lowers its front paws and body and shows airplane ears. In addition, cats also show airplane ears when comfortable or relaxed, so to know the exact meaning you must judge it together with the cat’s state at the time.
