People get goosebumps when they feel a sudden surge of emotion. Goosebumps are due to the shrinkage of the skin cells around hairs, making the hairs stand on end. Animals, such as lions and cats, develop the goosebumps or "piloerection", and the hair standing on end makes them appear larger or stronger, especially when they feel fear or anger. Human skin also develops goosebumps on instinct when a person experiences a sudden change of emotion.
