Is this poop or vomit?

I thought so but someone told me that it’s regurgitating if it’s mostly hair and it’s mostly hair, well it has two clumps of hair and that’s all it is. It was never really smelly it but it must have been a little old because it was really cold. I thought regurgitation looked like a mouse or body parts of a mouse, plus it would probably be pretty hard to not notice a regurgitated large mouse. It’s okay if it has clumps of just hair but nothing else right?

Hair isn't all that digestible. Every now & then a snake will defecate feces with a lot of hair in it, like brown coated ringlets, even- If the smell says poo, it's poo! Not all regurges look the same, and not all feces look the same either. The smell of a regurge is enough to make you gag...get it?
