A 7-year-old intact male guinea pig presented for inappetence and weight loss over the course of a month, lethargy, hematuria of one day duration, and being painful when picked up. On physical exam the animal was quiet, alert, and responsive. On abdominal palpation the patient was tense and possibly painful but neither masses nor stones were noted. Abnormal bony protrusions were palpated bilaterally on the stifle joints during restraint. Hematuria was observed during the course of the visit.

The problem list includes hematuria, weight loss, inappetence, and abdominal pain. The diagnostic tests that were performed included CBC, Chemistry panel, 2 view radiographs, and focused ultrasound on the urogenital tract. The treatment option that was chosen was medical management which included intravenous fluids, Oxbow critical care feed, Meloxicam 0.4 mg oral suspension, and Trimethoprim/Sulfamethox 12 mg oral suspension.

The seminar will discuss the work-up required for a urolithiasis case in a guinea pig, the different treatment options, and the supportive care required.
