An 11-year-old castrated male domestic longhair cat was evaluated for metastatic disease. The cat was being treated for osteomyelitis of the left side of the mandible, and a proliferative sublingual mass had been detected during physical examination. The cat had been anorectic for 3 to 4 days. No abnormalities were detected during auscultation of the thorax. Radiographs of the thorax were obtained during general anesthesia (Figure 1).

A 6-year-old neutered male domestic shorthair cat was evaluated for left pelvic limb lameness of 3 months' duration. The cat lived indoors but had access to the outside.
