Really what I would want would be an information booklet and a test for buyers. This could be done online or by mail.
The buyer would also have submit a description of the caging they will be able to provide.
There may be a few other considerations like the buyer must submit a signature from a vet stating that that vet is willing to treat or euthanize the animal(s) should the need arise. This could be a standard form that comes with the booklet & test.
Another form to be included would have to be signed by a reptile rescue that would be willing to take in the animal(s) if the buyer is no longer able to keep it. The buyer could skip this form if they are willing to pledge that they will have their vet euthanize the animal(s) if they can no longer keep it.
This should be run jointly by the government and vets. Vets would have to be accredited by the government just like smog checks are done with service stations. The government would charge a small fee for managing the paperwork and the vet would recieve a larger fee which would basicly be a prepaid euthanasia. That way euthanasia would be paid for before the buyer even gets the animal, which would eliminate the economic incentive a buyer might have towards simply letting the animal go. Since this fee is prepaid, and because most buyers are not going to end up euthanising their purchase it does not have to be as large as what a normal euthanasia would cost.
I also don't think Boas should be included in this at all except maybe on a state level.
