Bouvy Claushuis, [20 Sep 2022 at 21:23:06]: Hi everyone, any ideas what can cause severe dyspnea in a captive lioness of 12 years old? Within 1 week from noticeable signs she died. Same habitat, same pride, same food (60% chicken en 40% cow), dewormed with Ivermectin. Other lions in enclosure also seem to start showing mild symptoms of dyspnea. What are the most common (infectious) causes ? I didn’t see them myself yet, but will go there tomorrow Henry Labuschagne, [20 Sep 2022 at 21:26:37]: What was the Ivermectin dose used ? Route ? Was a PM done ? Bouvy Claushuis, [20 Sep 2022 at 21:33:09]: Ivermectin orally. Dose I have to check with caretaker. No unfortunately PM wasn’t possible
