Can you step back for a second and acknowledge why PCPs and other doctors might not immediately think "antibody titres" and other excessive testing when dealing with a patient who thinks they might have an ultra rare virus that kills 1-2 people per year in the entire country? You seem mad at them for the way they reacted.
A domesticated cat bit you and you went in for rabies concerns? I can't find any cat-human rabies transmission in the U.S. in all of the CDC surveillance data at all.
You have an irrational rabies fear. You need to move past it. Other people are not the problem here.
