From the 'Veterinarian's  Oath': 

"...I solemnly swear to use my scientific knowledge and skills for the benefit of society through the protection of animal health and welfare, the prevention and relief of animal suffering, the CONSERVATION OF ANIMAL RESOURCES, the PROMOTION OF PUBLIC HEALTH, and the advancement of medical knowledge.  I will practice my profession conscientiously, with dignity, and in keeping with the principles of veterinary medical ethics..."

The woman didn't violate her oath--she upheld its most important provisions (CAPITALIZED), with the possible exception of the 'dignity' part for being stupid enough to brag about it on FaceBook, and inevitably sending the cat-nutters and other weak, worthless weeble-wobbles into paroxysms of shrieking and flailing.

Here's an idea, Ms. Moran: if you want little fluffy to be safe, KEEP the FILTHY THING IN YOUR HOUSE.  That way it won't be killed by car, the big bad wolf, or fly away in Mr. eagle's talons.  And I won't shoot it.
