http://www.theelephantinthelivingroom.com/A pretty highly regarded documentary about Americans keeping dangerous exotic animals as pets.
I'm watching it now, it's more biased than fair, but still fairly interesting.
While I've never understood the desire to keep exceptionally poisonous snakes, spiders, or reptiles. I really don't think I have an issue with people keeping exotic pets, as long as they're well cared for and in secure facilities.
