You don't want your snakes drinking ONLY distilled water, but it's better for misting because it doesn't leave hard water stains everywhere. I don't think you need to
worry about a snake that drinks SOME distilled water, as long as that's not ALL they drink? That's a great question...for snakes that mostly drink droplets, if that was
my situation I'd probably alternate them. I think you should start a specific thread for this...I don't keep any snakes this applies to & like you, I wonder what other
keepers (of GTPs etc) are doing? They might not find your question so easily buried in this thread?
