A 12.5-year-old sexually intact male Prevost's squirrel (Callosciurus prevostii) was evaluated because of rightsided facial swelling and a recent history of dysphagia and stridor. The squirrel was anesthetized to allow for physical examination and collection of blood samples. Physical examination revealed a fracture of the maxillary right third premolar tooth and an associated abscess. Results of hematologic and serum biochemical testing were within reference limits for this species. While the squirrel was anesthetized, radiographs of the skull were obtained (Figure 1).
