Because animals cannot verbally communicate discomfort, changes in their normal behavioral repertoires serve as the first warning signs of underlying pathology.

A change in behavior is often the very first sign of sickness. For example, a normally affectionate cat that suddenly hides may be experiencing underlying kidney pain or arthritis.

The study of animal behavior and veterinary science are intricately linked, each informing and enhancing the other to improve our understanding and care of animals. Animal behavior, the study of how animals behave, interact with each other and their environment, provides critical insights into their needs, stressors, and overall well-being. Veterinary science, on the other hand, focuses on the health and diseases of animals, aiming to prevent, diagnose, and treat medical conditions. Together, these disciplines play a pivotal role in enhancing animal welfare and health.

In animal shelters, chronic stress alters behavior rapidly, making animals appear unadoptable due to barrier reactivity or extreme withdrawal. Veterinary behaviorists design environmental enrichment programs—such as kennel rotation, puzzle feeders, and structured socialization—to maintain the psychological health of shelter residents, drastically increasing adoption rates.
