Naturalist Casey Anderson and his longtime friend and cat expert, Tyler Johnerson, set out to track one of North America's most elusive ghosts: the mountain lion. This Episode is being listed under Season 2010 and 2011 due to the fact the only place there is a listing for all these episodes seems to be on Amazon, where they have 2 items with separate episode listings in them: Season 2010 and Season 2013. This item will be duplicated in Season 2011 simply due to the fact that it is obvious that this episode aired in 2011 and not 2010 based on the first aired date.
