I ended up buying a Kenyan Sand Boa in October. But we just got a rescue Rosy Boa that was surrendered to PetCo, too. It does not have mites - I have checked. Thank goodness. It is very docile - no problem. But it seems to have stuck shed on it's eyes. So hopefully, the next shed will go better. He was given up for "not eating." We've only had him two weeks and so far he's eaten three times - 1st a live pinkie mouse, 2nd two live pinkie mice, 3rd a F/T pinkie mouse! So he's already converted to F/T. Yeah!
Glad the BP worked out for you. They are GREAT snakes. We have one, too.
