So a few times I thought I heard my snakes cough, but every time I check on them, one had recently pooped. Every single time. So I figure they're just farting when they poop. It's been like 4 times in maybe 7 months.

It it sounds like a cough to me because it's not a low pitched growl that was summoned from the depths of hell.

Does anybody have have any experience with the sound snake fart or a snake cough?
