Frankly, this appears to me to be just another scare story spread by organizations with hidden agendas. I see nothing to indicate that any state or federal law has been passed, much less implemented, that would require families with a pet duck or bunny to register and have their "premises" subject to inspection. And if any pending legislation is worded in such a way that it could be interpreted as requiring that, it will no doubt be revised before having a snowball's chance in hell of passing.
A couple of years ago, another scare campaign like this was in full swing, spreading around internet pet-health message boards and e-mail groups like wildfire. The claim went along the lines: "There's this horrible law that was drafted by the American Veterinary Medical Association that about to be passed in many states, that would make it illegal for anyone who is not a licensed veterinarian to treat an animal or even give advice on treating an animal. Those of us who want to get holistic therapy for our pets, or reiki, or . . . . would just be out of luck because all the practitioners would be legally barred from helping us. Farmers would be breaking the law if they treated any common condition that they've been treating themselves for centuries. This law would even make message boards like this one illegal!"
The facts? The draft legislation was intended to be incorporated in states' professional licensing statutes, all of which limit the restrictions to people who are taking money for performing whatever activities are deemed to require a license. No information-sharing message boards would be illegal, farmers would be perfectly free to go on doing what they've always done, and there were liberal exceptions (as in the current laws) for non-veterinarians such as farmhands and animal shelter workers to perform procedures and administer medications under the very general "supervision" of a veterinarian (meaning if the farmer has the vet out once a year or so, and says I'm doing X, Y, and Z like I always have, and the vet says fine, then the farmer is free to continue all these treatments and medications, including castrating piglets, adminstering vaccinations, and all the rest). The scare campaign was originating with self-styled for-profit practitioners of all sorts of new-agey "treatments" for pets, who often discouraged their clients from seeking any real veterinary care. The increasing popularity of these "treatments" and increasing frequency of vets seeing animals brought in who had been suffering through the "treatments" while not getting proper diagnosis and treatment for what would have been easily treatable conditions if they'd been addressed in time, prompted the AVMA to draft some model legislation designed to crack down on these businesses. The "I can cure your cat's kidney disease with aromatherapy for just $50 a session" crowd fought back hard.
Let me know the first time anyone gets an actual legal notice that they have to register their home as an "animal operation" and register their kid's pet duck and let the instpectors in, and I'll join the bandwagon. But I'm not holding my breath. State and federal legislators have kids with pet ducks and bunnies, and know people who do, and remember having them as kids themselves, and they're also really fond of getting re-elected.
I'm going to hope you're right, but I'm also going to be watching close.
