What behavior might a suffering animal display other than aggression?

A suffering animal may display vocalizations or hiding as a way of expressing its distress or discomfort. Vocalizations can include whimpering, whining, or growling, which signal anxiety, fear, or pain. Hiding is another common behavior, as animals often seek refuge when they feel unwell or threatened, preferring to remain in a safe, secluded space.

These behaviors are instinctual responses to pain or fear and serve as a mechanism to cope with their suffering. In a natural environment, hiding can also provide an animal a chance to recover away from potential threats. The significance of vocalizations and hiding emphasizes the importance of recognizing these signs in assessments of an animal's health and wellbeing.

In contrast, behaviors like welcoming interaction, increased playfulness, and excessive eating are generally more indicative of well-being or normal behavioral patterns, suggesting a lack of distress. Hence, vocalizations or hiding are more reliable indicators of an animal's suffering in comparison to those options.
