Well, sometimes it pays to believe someone telling what to do, instead of believing others who don't know what to do and/or who make things worse daily.
Almost thirty years ago ND/holistic health givers were able to remedy cat allergies "naturally". Some companies nationwide or worldwide were able to also, simply, effectively and inexpensively. Oh, yeah, those are the same reasons 'regular' ama doctors don't help - it is too honest, too simple, too effective, and quashed by bigpharma whenever possible, in order simply and effectively to sell a lot more drugs, for power and for profit and for control.
