If the bleach fumes were *strong* (enough to make you cough), and we are talking Ball Pythons: Given that you definitely have to ventilate the area-I would also lower the humidity of the room for the next 2 weeks to decrease the likelihood of opportunistic respiratory infections that may take hold...I have one BP male that is 15+ years old and would totally use this as a reason to develop an RI.
