HAVE HED ALLERGIES MY ENTIRE LIFE. DUST, MOLDS, WEEDS, GRASS,TREES, AND CATS. ENDURED SHOT FOR 18YRS. ABOUT 8YRS AGO I GOT A CONCUSION LOST SMELL AND TASTE. A FEW YEARS AGO I GOT A CAT AND HAVE NO SIGNS OR PROBLEMS REGARDING ALLERGIES. BEFORE I COULD NOT HAVE ANY CONTACT LET ALONE SIT IN A ROOM WHERE A CAT LIVED WITHOUT A REACTION. JUST CURIOUS AS TO WHAT YOU HAVE TO SAY. OR AM I A PERFECT SCIENCE PROJECT?
