I started stunning when I rescued a BP that was partially blind casue of badly capped eyes from poor husbandry. I wanted her to eat live... but she was at a disadvantage becasue of her sight... Now her eyes are all cleared up and she snipes active rats from almost 2 feet away. I have no prob feeding her active rats now considering she gets them right around the snout eachtime keeping there head bit shut, while she constricts.
