I would never recommend a big snake for a pet. It takes work and commitment that most people who buy them don't realize and most of them live poor short lives. I helped get legislation in my state passed to make it illegal to purchase the bread I have or have them after a certain size unless your a zoo.
I'm totally committed to my best buddy though and he and I are in it together for the long run. I don't have many visitors and he's a deal breaker for most women but he's totally worth it!
