1) If passed, it adds all 4 species of anacondas, boa constrictors and their subspecies, burmese pythons, reticulated pythons and northern and southern African pythons to the Lacey Act. This means no importing or transporting across state lines. Otherwise, you can keep the animals you have but if you had to say move to another state, you can't take them. If you breed, you can't sell out of state.
2) See #1
3) It's passed the Senate subcommittee
4) It will go to the Senate floor for a vote. It then has to pass the House and then be signed by Obama. I'm specifically talking about S373. There are other bills out there.
5) The next step being asked is to set up an in person meeting with your senators or their staff. This is done by calling their office.
Hope that clears it up.
