Found parasite or undigested food in stool

[Bogertophis]

It's about an inch long, and I'm certain its organic but its very touch, which is what leads me to believe its probably a bundle of nerve fibers from the rats spine/tail. Nasty.
I've never heard of nutribac but I'll look into it

Nutribac is a probiotic for snakes. If your snake has ever been given an antibiotic (even before you got him or her) this can improve digestion by helping to restore the necessary & beneficial gut flora that would have gotten wiped out after a course of antibiotic therapy. (Bene-Bac is a similar product)
