exact cause of death is still unknown because its eating and excretion were normal. No traces of venomous animals that might have wandered into its enclosure were found on its external body. Therefore, we have asked the Director of Wildlife Conservation and the Director of Conservation Area Management Office 12 (Nakhon Sawan) for their assistance in having the veterinarian from Conservation Area Management Office 12 jointly examine the carcass to find the true cause of death.
