I'm already a worried snake-mama. I have seen the hair in feces of my all of my snakes, and i have 7 different species (ball, garter, boa, corn, hognose, kenyan, carpet). I have to say i was under the general impression that ball pythons did digest the whole prey item, however. But, i *have* seen the hair in the poo, so it can't be denied.

Garters eat mostly fish.
One hognose has taken to the fish, as well. Little brat bit me because he wanted fish *lol*
