With the amount of reptiles we keep at our rescue, we use a vet who specializes is herps and NOT a 24 hour vet service. Personally, I would ONLY see a herp vet in this situation because if it turns out to be IBD, the snake will have to be put down. I would never take a chance on the life of my snake by putting it in the hands of some 24 hour vet who does not have much herp experience. Most small animal vets are not herp vets and do the best they can, but when it comes to the care of my reptiles, having the BEST care is the most important and I would prefer a specialist. I'm sure they do as well.
