Animal stress responses are the ways animals react to threats or challenging situations in their environment. These responses often include physical changes, like increased heart rate or rapid breathing, and behavioral changes, such as fleeing, hiding, or aggression. Some animals release specific hormones, like adrenaline or cortisol, to help them cope with danger. These adaptations help animals survive in the wild by preparing them to either fight, flee, or adapt to stressful situations.

Predators, illness, injury, loud noises, confinement, limited resources, social conflicts, or abrupt environmental changes; stressors can be short-term (acute) or long-lasting (chronic).
How do scientists measure stress in animals?
By observing behavior and physiological markers such as glucocorticoids (e.g., cortisol), heart rate, respiration, and activity; sampling methods should be interpreted carefully as they can influence results.
What are common signs of stress in animals?
Changes in appetite, grooming habits, sleep, hiding or aggression, restlessness, pacing, panting, vocalizing, or altered posture; signs vary by species.
