It's a real shame that Kallari ingested some Reptibark. It's not as if snakes in the wild don't ingest debris too (as some always like to point out) but when they're our pets, I think prevention is the better way. Snakes have strong digestive enzymes but only for their normal foods...they cannot, unfortunately, digest wood or other plant fibers, & such debris can cause an obstruction or even a perforation...it's very hard for a vet to fix that, even if you had realized in time.
