I should state that what I mean when I say leave water in the enclosure is that I leave a two oz. water dish with fresh water for drinking. If I notice an animal going into shed or see one trying to soak(they don't fit in two oz cup)I usually just spray them once or twice a day (not enough to build up droplets on the cage)I have never had a problem with regurge related to water. I have had gravid females regurge when they over eat and have seen rosys, rubbers and kenyans regurge if they eat just before or during a shed.
