Hairball???

[redshepherd]

I found what I initially thought was a regurgitation in my couperi's tank, but it was very light and completely dry. It was white and dry... When I broke it open, it's literally completely clean white fur. Basically a long hairball.

I read around that some snakes will poop out hairballs? Or is it being coughed up?

I'd just like to know if hairballs are common and if it's coming out the correct end (the back lol). I've never seen a snake hairball before.
