A little over a year ago we had severe consequences from Merial's Imrab for rabies. It happened four months apart in two different ferrets. Both ferrets developed identical symptoms of severe respiratory congestion and consequent weight loss. One recovered fully. The older one, however, who was 5 at the time, never regained her weight and is now declining at 6 1/2. She recently became jaundiced. Merial never responded to my letter about the problem but our vet filed a report with the appropriate agency. Fortunately, the respiratory congestion did not occur after this year's rabies vaccination. Alice [Posted in FML issue 3362]
