The physical pain of using the litter box creates a negative association; the soft, cool surface of the bed becomes a safe alternative. The takeaway for practitioners is a diagnostic rule

General practitioners are also learning. Veterinary schools are increasing behavioral science hours, and continuing education (CE) conferences now feature full tracks on topics like "Low-Stress Handling" and "Pharmacologic Interventions for Noise Aversions."
