A 2-month-old intact female African pygmy hedgehog (Atelerix albiventris) presented with a 1-week history of vomiting. Radiographs and ultrasound were performed but were inconclusive. The vomiting was unsuccessfully treated with famotidine and progressed over the following few days. An abdominal exploratory was performed and biopsies were taken of the stomach and small intestine. Histopathology revealed an eosinophilic gastroenteritis. Fenbendazole was initiated to rule out parasitic infection. No improvement was made, and prednisolone treatment was started. A diet trial using a feline hypoallergenic food was started 1-month later to rule-out food sensitivity. Vomiting improved with ongoing prednisolone and diet therapy, but then soft stools developed. Dysbiosis was diagnosed with fecal cytology and improved with metronidazole treatment. There were 2 episodes of regurgitation and omeprazole was added to the treatment plan. The hedgehog presented 20 months postdiagnosis maintained with prednisolone, omeprazole, and psyllium supplementation with no relapse of vomiting.
