The only people who really care is the pet industry because, just like the FDA, it effects their bottom line... profit.
The FDA is made up of people that are doctors, pharmacists, food industry people and such and is very political. They have a war going on with the natural food/supplement/vitamin industry because those industries affect their profit. They don't want people taking those supplements and becoming healthy because then they don't buy their drugs or go to the doctor as often. Why do you think that the statement on the vitamins and natural food supplements says, "This product is not intended to diagnose, treat, cure or prevent any disease." The FDA requires that statement on all natural supplements and vitamins because it cuts into the profits of drug companies, doctors and food industry companies. According to the FDA, nothing can cure or treat any disease unless it is a drug, i.e.- their drugs.
I believe that you have to look past the initial subject here and try to see the reasons for this "urgency". Obviously, it is having an impact on the profit margin. If they allowed this to go on it would effect profits in all sorts of pet related industries such as the dog food industry and veterinary industry. JMHO.
Sorry, all you veterinarians out there. I don't mean to step on anyone's toes in particular, but this is just my opinion. Flame away!
