Re:
I don't think there's anything wrong with your snake. =P
If I recollect rightly, I think after my female motley eats a weaned rat, the first poo appears in 4-6 days and it's got an odor and gelatinous looking black and white stuff. Then, I'd say a couple weeks later, she'll pass another glob and when it dries, looks like matted fur.
I imagine she retains stuff that takes longer to digest, such as hair and bones, and the easiest stuff to digest would be the rodent's viscera. So likewise, the first that gets expelled is the visceral waste, and then the bones (if any) and hair.
Hair is a tough thing to digest and I don't know of many animals that can. When I walk through the woods here, I can see animal droppings full of fur, mostly rabbit, and after a week or so, that's all that is left, hair. Owls vomit up balls of hair, bones, and teeth. So in all honesty, I don't think your snake is sick, she's just doing what is natural for her.
