Abnormal behavior often results when an animal is housed in an environment where it is exposed to chronic aversive stimuli, where it cannot perform behaviors normally essential to reproduction or survival in the wild, or where it cannot perform behaviors that would correct the homeostatic imbalance it is experiencing.

• A. Cannibalism
• B. Abnormal aggression
• C. Abnormal behavior
• D. Stereotyped motor patterns

Answer: (C)

When animals can’t express normal species-typical behaviors or can’t maintain their internal balance due to the housing environment, they often develop abnormal behavior as a response to ongoing stress and unmet needs. This broad term captures the range of maladaptive actions that arise from behavioral deprivation and homeostatic disruption, not just a single specific action. The scenario describes conditions that so restrict or frustrate the animal—chronic aversive stimuli, inability to perform essential reproductive or survival behaviors, and an inability to correct physiological imbalances—that a general category of maladaptive behavior emerges. That makes the broad label the most appropriate way to describe what’s happening. Cannibalism, abnormal aggression, and stereotyped motor patterns are particular forms that abnormal behavior can take, rather than the overarching concept itself. They illustrate how the same underlying welfare issues can manifest in different ways, but the most encompassing term for the phenomenon is abnormal behavior.
