The reason cats are most afraid of the twitching right eye is because the twitching right eye may mean that the cat is preparing to attack. In the wild, cats often use their eyes to indicate their intentions. When they are preparing to attack, for example, their eyes become larger to be able to see their target better. When a cat's right eye twitches, it may mean that it is paying attention to animals or objects around it and is preparing to attack.
However, it may also be caused by the cat's physical health problems. If your cat's eyes frequently twitch, it's recommended that you take him to the doctor to make sure he doesn't have a medical problem. Generally speaking, the reason cats are most afraid of a twitching right eye is because it may mean that it is preparing to attack, but it may also be caused by a physical health problem.
