IF this is a true allergy or sensitivity:
My brother's 1st visit to my first house resulted in him being shocked because he'd forgotten at the time that I had my 2 furkids (they were about 1 yr. old then), yet didn't react at ALL to their presence despite supposedly having severe allergies to cats. I'd read back then that keeping them well-groomed could help eliminate such allergic reactions in susceptible people.....and that is what I'd been doing with them since the moment I'd adopted them....but for their OWN good health. Every few days (a week at most) I'd brush and then comb them thoroughly with one of those stainless steel, fine-toothed combs for animals. They were also short-haired, which probably also accounted for less dander in the first place, which a truly healthy diet
also helps keep down....not that they had that at the very beginning, when I was more ignorant of such things. Some people suggest bathing a cat weekly so their people don't suffer with allergies, but then that's not the best solution, especially for the CAT, since their skin is very sensitive, most products aren't pure enough to not cause THEM any harm, and they can get skin problems themselves from such repeated bathing. (there's a REASON cats don't jump into water to get clean!)
Having said that, though, for ANY of you who suffer from allergies (of any type), you might consider trying NAET allergy
elimination technique, which has been proven time after time to absolutely cure people of allergies for good. One of our vets practiced this as well and had great success with it, both for animals and their people. You just have to find someone in your area who's registered to practice it. Here's the site for it.

There ARE solutions out there - you just have to be open to finding and trying them.
