The jaguar (Panthera onca, Linnaeus 1758) and cougar (Puma concolor, Linnaeus 1771) are the largest cats in the Americas and are listed as uniquely extinct in El Salvador, Central America. The contributory factors for this event are little understood and/or ignored. This omission hampers conservation planning for declining big cat populations in other countries. A thorough review and analysis of the literature reveals important gaps that impede assessment of the factors for big cat extinction, and also possible meliorative efforts. The evidence questions the commonly blamed civil war and deforestation, and critically assesses a wider set of factors mostly not linked to big cat extinction; dense human population, small national territory, border porosity, cat adaptability to modified land cover and the actual importance of connecting forested corridors. The evidence from other countries shows possibilities of cat adaptability to all possible factors for extinction, but also hints at the possibility of the lack of connecting corridors as uniquely negative in El Salvador. Reintroductions of big cats in El Salvador must include internationalized assessments of their ecology and public tolerance of cat presence. It is imperative that generalized assumptions of cat extinction, e.g. the civil war and deforestation, and human population density are critically reviewed. Full conservation of big cats in the region requires reintroductions based on such critically acquired knowledge, rather than further debate
