Now personally I am getting both as well and I have had boas for almost a year now and absolutely love them. They are awesome eaters and every once in a while can be a little pissy but other then that are awesome snakes to have.. The carpet are great too I cant comment to much on that only because I havent had one yet but im excited to test it out.
