No amount of evidence will convince a fool. -- Mark Twain.
Dad was a game warden. He saw the mountain lions on Ft. KNOX. He helped take plaster casts of the tracks. 2 of my uncles saw them. Hunters saw them. They exist and are here. And breeding. (Mamma lion, 1 cub, verified) has to be a daddy somewhere)
In all the mt lion stories, there has been one documentation from the 70's. It was indeed a cub hit by a car in eky. After testing, the cub had DNA from the pet trade. So either it was an escaped pet, or it broke into someone's house and bred with their captive mt lion.
Here is the deal, these things aren't that elusive. Illinois just had a mt lion wonder in, they had countless trailcam pics and then it was hit by a car. Proof is readily available when they exist.
This topic has been going on for 10 years just on this website. Still not a single shred of proof from ky. One will eventually wonder in, but right now it's just a bunch of malarkey.
