The mortalities of exotic felids that have been raised in Everland Zoological Gardens within a designated period (1976∼2001) were retrospectively analyzed based on the clinical charts and/or autopsy reports. During that period, a total of 154 exotic folios from 5 species were died. Noninfectious and traumatic factors, respiratory and digestive disorders account for the majority of cause of death. 40% of the death was concentrated in the winter season. The mortality of female and male was 55% and 45% respectively. The mortality of newborn folios(57%) were significantly higher than that of adult(32% and juvenile felids(11%) due to neonatal problems.
