When you consider miracle products in the pet trade (in the USA), keep in mind that there is no governmental organization for the pet trade (like the Food & Drug Administration for the drug trade) that keeps people/corporations honest. You can make any claim about your product that you want to, and no one will call you on your claim...
I know of one individual who, twenty years ago, elected to go into the pet business because it was the least regulated business he could find. He made a pretty good run of it...
And, remember that anyone who "invests" in a miracle product has a vested interest in claiming that it works - otherwise they'd have to admit to being dopes for buying it in the first place.
Caveat emptor,
