Mom here, Vito refused to write since this post does not pertain to him. And he hates that. Just wanted to update you all - Vinny got his staples out on Wednesday. The doctor said the results of the pancreas biopsy were basically inconclusive, and that we won't really know if anything is wrong unless he has problems with digestion.
As for the shunt surgery, the plan is to re-test him after 3 months to see if the shunt repair "worked." They said it won't be known until at least then (possibly even 6 months!), as it takes time for the band to re-route the blood flow. It is also even possible for the shunt to set up in another area - we definitely do not want that!! So for now we wait!
Vinny had some fun at the vet though - with the vet's turtle! It was wandering free when we got there and he was not having it! How howled, and whined, and basically talked, telling the turtle that he had some nerve being all up in Vinny's space!
