Ruffled fur is a common indicator that a mouse may be unwell. When a mouse is healthy, its fur typically appears smooth and well-groomed. However, when an animal is sick or experiencing stress, its fur may become unkempt or ruffled, signaling to caretakers that something could be wrong. This visual sign can help in early detection of health issues, allowing for timely intervention.

Bright eyes and active behavior are signs of a healthy mouse, while excessive grooming can occur both in healthy animals and those experiencing stress, making it a less reliable sign of illness compared to ruffled fur. In veterinary care and laboratory settings, monitoring these physical signs is essential for maintaining the welfare of laboratory animals.
