for the record, if you happen to be near a zoo with a snake house (or that has snakes,) you could probably ask the zookeeper. If they didn’t know already they have snakes and probably wouldn’t mind setting that up. (they also probably have multiple identical dishes and such like.)

well. I suppose that could be an email, if you happen to be not close. But if you are, I’ve never met a zookeeper that didn’t love to talk about their animals and answer random questions like that.
