They are both Boa's, and the fact that they are from different Continents doesn't matter lol The fact they are both Boa's makes it possible for them to breed, they have descended from Boa Constrictors, and there are many sub-species of the Rainbow Boa's, including one from Columbia. It would be more about if you were able to get them to breed, they may not see the other sub-species as a attractive mate, but the problems don't end there. A lot of the eggs may not come to term or fertilize, at least not as many as a normal clutch. I don't Kno why all the female are getting all worked up about this, like its some unethical animal experiment. I consider the breeding of Ball Pythons for colors unethical.
