History, clinical findings, blood cell count\u2010based ratios, thoracic radiographs on presentation, and outcome were reviewed. The Animal Trauma Triage (ATT) score was assessed in each cat and classified as mild (1\u20133), moderate (4\u20137), and severe trauma (\u22658). Forty\u2010eight healthy blood donor cats served as the control population.
