Research overview: behavioral recognition of pain in cats

Because cats evolved to conceal vulnerability, they display pain through subtle behavioral changes rather than obvious distress, and research has cataloged the signs, including reduced activity and jumping, altered grooming, changes in posture and facial expression, hiding, decreased appetite, and temperament shifts. Recognizing these cues is essential, since overt signs often appear only with severe pain. This overview synthesizes the behavioral and welfare literature rather than one citation, describing the range of behavioral indicators of feline pain, why owner observation of changes from normal behavior is crucial for detection, and how this understanding underpins the validated pain scales. It matters because the historical undertreatment of feline pain stemmed largely from failure to recognize it, and improved behavioral awareness, both in clinics and at home, is fundamental to ensuring cats receive the analgesia they need.
