What type of behavior may indicate that an animal is feeling pain?

Isolation from the herd is a significant indicator that an animal might be feeling pain. Animals are typically social creatures that thrive in the company of others in their species. When they start to isolate themselves, it can be a clear sign that something is wrong, including experiencing discomfort or pain. This behavior suggests that the animal is not only avoiding interaction due to distress but may also be trying to protect itself or conserve energy.

Increased activity, excessive vocalization, and normalized feeding behavior do not consistently indicate pain. Increased activity could be a sign of excitement or stress rather than discomfort. Excessive vocalization can be associated with various emotions, including fear or excitement, rather than specifically with pain. Normalized feeding behavior usually suggests that the animal is feeling well and is not in distress. Each of these behaviors could stem from factors unrelated to pain, making isolation from the herd a more specific indicator in this context.
