For the sake of the community, I think it would be good to post the name and location of the vet who gave you this half assed and dangeroous advice.
That way, other members can be spared being fed a line of crap and having to euthanize an animal that may have been just fine.
Now before you restate again what that quack told you, let's correct some stuff have been were told:
1. IBD is rare. It is even rarer in ball pythons. There are many things that could have been going on with your snake. Most of them conditions that could have been addressed. Most of them conditions that were not causing the animal any pain or suffering.
2. IBD often times does not present with any neurological symptoms.
3. Dr. Hack McQuack had no way of telling whether or not that animal was suffering.
4. IBD does not kill ball pythons quickly.
You were robbed of the examination fee and the euthanasia fee by a hack vet who didn't know her left ear from her ass. You can rationalize that you did the right thing over and over again despite what Nikki is trying to tell you but the fact remains - you euthanized a snake that may have been fine on the advice of an ignorant vet.
Please post the vet's name so that any members in you area can avoid her like the plague.
