I know chitin is a component of insect shells, but what is it exactly? Protien? Fiber? I mix a little Sunseed hedgie food in with my hedgies cat food mix because it has chitin powder listed as an ingredient, and it seems logical that it would be good for the hedgie, as it would be a part of their natural diet. Maybe it is good for quill development? Am I just barking at the moon? Help on this is appreciated! Thanks.
