When do cats' pupils run? - in detail
Cats' pupils dilate or constrict in response to varying light conditions and emotional states, a process controlled by the autonomic nervous system. In low light, their pupils expand to allow more light to enter the retina, enhancing their ability to see in the dark. Conversely, in bright light, their pupils contract to protect the retina from excessive light exposure. Beyond light regulation, a cat's pupils can also dilate due to heightened emotions such as excitement, fear, or aggression. For instance, during play or hunting, their pupils may enlarge to improve focus and depth perception. Similarly, in stressful or threatening situations, dilated pupils can indicate arousal or readiness to react. Additionally, certain health conditions, such as hypertension or neurological issues, can cause abnormal pupil dilation. Observing a cat's pupils provides valuable insights into their physiological and emotional state, making it a key aspect of understanding feline behavior and health.
