WTF: The monster of Riegrovy Sady

Ok it's not a monster, it's a mountain lion, also known as a cougar, also known as a really fucking big animal that can kill you. This picture was taken during the day by a friend. I personally saw the thing while cutting through the park one night. Usually I get a little creeped out doing that at night because who knows what kind of weirdos are lurking in the bushes. But now, I can also be afraid of wild animals that have been 'domesticated.'

The best part is this little leash thing the owners have it on. Like a leash is going to prevent this thing from doing what it likes to do, such as gnawing on humans, chasing prey and mauling things.

Also, this raises some strange questions. Clearly the owners live nearby, as I doubt that animal does well in the car. The park is surrounded only by apartments, so somebody is living in an apartment with a cougar. What does one feed a cougar? Is this even legal? And what's the best defense in a cougar attack? Should you play dead, kick it or yell 'what's that over there?!' and then run away when it looks?
