Could this be vomiting? because from my search, regurge is something that hasn't reached the stomach to digest, but this he digested other parts but the fur and throwing that out. Since he pooped two times, feels like digestion happend but the fur did not get digested... I don't see any factors of him possibly doing it because, I don't consider him as bad feeder, husbandry I check 2~3 times a day, I don't handle him for 2 full days and even then, not so long. I am contacting the vets but so hard to find exotic vet.. one I know, she went somewhere for few months.
vomiting would happen immediately after swallowing. anything that comes back up instead of passing all the way through is a regurgitation. the definition of regurgitation explains partial digestion.
a bad feeder, meaning the prey item you fed might have been bad.
