What happens if you keep scaring a cat?

Frequently scaring a cat can lead to serious consequences. Repeated fright creates lasting psychological stress, which may cause anxiety, fear, and tension, and in severe cases can trigger a stress response that harms the cat’s physical and mental health. After being scared, the cat may lose trust in its owner and hide or even act aggressively when it sees them. Long-term tension and fear also lower immunity, making the cat more prone to heart disease, digestive problems, and skin conditions.
