Footage of alleged Aussie mystery cat

Australia, it sometimes seems, is simply riddled with unexplained catlike predators. Panthers, lions, and unknown striped beasts - you name it, it's been reported. This account in the Australian press shows a still of what certainly looks like a mountain lion (Puma concolor), a North American species that seems to have somehow gained a toehold in Australia. (Abandoned mascots brought by American units in WWII are one theory.) No one has caught or killed such a cat, but tracks and dead livestock, combined with eyewitness accounts, make a strong case that something is going on.
