Health providers have been able to take cat dander, hair from a brush used to brush the cat, and somehow within a week or two make a very specific help from it that provides relief quickly. Since it is forbidden by u.s. federal law, advertising this or someone who does this is not often seen.What does ND stand for? Please can you provide a reference to the holistic health givers remedy for cat allergies? Thanks....whatever it is I need some.![]()
