One more comment about the mountain lions of British Columbia, at least those around the central part. They are a beautiful silver grey. I remember seeing a couple in New Mexico and they were light tan.
My father knew Badger Clark when he was a ranger. Clark had a pet lion, raised from a lost or abandoned cub. Quite docile. He was playing with it once, mock wrestling. The lion playfully swung a paw and hit Badger on the side of the head, knocking him cold. When he came to, the lion was licking his face, the coarse tongue almost making it raw.
Not all that large, but these cats are powerful.
