You couldn't be more wrong thicketmaster.
First, biologist knew that mountain lions had been working down the Missouri River drainage for decades, and had predicted they would eventually work their way into MO, which they did. Wandering mountain lions have also been documented into central IL. EVENTUALLY a few mountain lions will make it down the MO and MS River drainages to the OH and TN River drainages, which will bring them into western KY and even northwestern TN. As of yet, that hasn't happened, but it will, and not too far in the future.
Second, there are no black "panthers" in North America. We have mountain lions, not panthers. Black panthers (actually, melanistic jaguars), are native to Central and South America, No jaguars have been documented north of central Mexico.
Third, there has NEVER, EVER been a documented case of a black mountain lion. Mountain lions, including those in Florida, do not have genetics capable of producing a black phase (the do not have the capability for melanism, like deer and other species do). It is not in their genetic make-up. There are no black panthers in Florida, nor west of the MS River.
