Ive seen one near Warrensburg, Missouri last year. i saw him crossing a field into some timber. funny thing is, when we saw the landowner he said "if you see a mountain lion let me know, cause he killed one of my ponies." We didnt mention a thing to him about it until he mentioned it. Me and my buddy looked at each other like "oh s*^%".
Another friend of mine caught one on his video camera, sent it in to the MDC, and they said "all we can say is it is not a house cat."
