I had a friend who used to work at a pet shop, and people would come in all the time and ask for big pythons and anacondas. First thing she'd ask is "Do you know how big these animals get?" and when they said yes she'd ask "Do you have a cage to house it in when it gets that big, and would you know what to feed it?" They'd almost always say "I'd probably just get rid of it before it gets that big." She wouldn't sell to them. It's like when I used to work in East Oakland and guys talked about getting rid of their pitbulls for rottweilers, when rottweilers became "the" dog to have. Dude my dog is a member of my family I wouldn't get rid of it to get something cooler. This reminds me of all the stories like the python they found in Arkansas that ate someone's pitbull.
