Which of the following is NOT a suggested indicator of pain in animals?

Normal eating habits are indeed not considered a suggested indicator of pain in animals. Typically, when an animal is in pain, it may exhibit a variety of behavioral changes that reflect its discomfort. Changes in vocalization, such as whining, growling, or other unusual sounds, can indicate that an animal is in distress. Similarly, antisocial behavior, like withdrawal from interaction with humans or other animals, may suggest that the animal is experiencing discomfort or pain. Restricted movement is another behavioral sign, as animals in pain may avoid using a limb or engaging in activities that require physical exertion.

In contrast, maintaining normal eating habits generally implies that the animal is not suffering from acute pain, as pain can often lead to changes in appetite. Thus, recognizing normal eating habits as a reliable indicator means the animal is likely comfortable, making it the correct answer in this context.
