I'm not sure what Gus has said but I've never kept any Hoggs at that temp. range. I keep them from 82-92 degrees F max. If the temperature range is to high the prey can putrify inside the boas body through excessive bacterial growth leading to regurge. The regurge can cause excess acid in the mucous membranes especially in the throat and mouth area. IMHO I think your animal needs an area to cool down a little and can't do it under your current conditions. Regurge in a boa is never normal and is the beginning of the end if you don't correct it early.
