WLF is trolling you. Black panthers are right up there with Bigfoot. We have Choctaw folklore to thank for those big black cats. "black cougar" simply does not exist. The only black panthers in existence are black jaguars found in South America and black leopards that live in Asia and Africa. Their are some cats in central america who have a melanistic phase but they are small, less than 35-40lbs
It falls under the cryptid category, same one as Sasquatch and Nesse. Louisiana does not have a breeding population of cougars, of any color. Last cougar found in the state was in 2009 and it was genetically linked to a population in New Mexico.
Check your facts Mayo!
