Well, that freaked me out.

Huh, I had no idea that it was normal for boas to drool sometimes. I've had her for a year and never seen it happen.

Well, they don't drool like a dog might. But immediately after drinking, if they're disturbed, they might dribble the water that's still in their mouths. A lot of snakes do that, not just boas. I was being funny when I said they can't hold their licker.
