Hair, scales, feathers, are roughage, and are an important part of a reptile diet. Healthy reptiles do not have a problem passing these, in fact, its needed to maintain health.
This is true with Wild and captive reptiles.
Weak, sick, dehydration individuals can become impacted with hair, feathers, scales or exo-skeletons. This is a sign that the individual is not in proper health. These animals should be taken to a Vet. The owners should also review their husbandry to make sure the problem is not their fault.
Good luck FR
