Psychogenic alopecia in cats is a stress-driven overgrooming condition that requires both ruling out medical causes and addressing psychological triggers.
Cats that overgroom are managing chronic anxiety through a displacement behavior. The underlying psychological distress is the welfare concern - hair loss is merely a visible symptom. Many cats with psychogenic alopecia have been living with significant chronic stress that owners have not recognized. Addressing the underlying stressor rather than just the symptom is the welfare-optimal approach.
