Is it possible to be only allergic to 1 of your 3 cats? My eyes get red and puffy when Jack lays next to me (and of course when I'm petting him), but not when I pet any of the other kitties. Jack used to be my mom's cat, and her asthma got too bad to keep him. Is he some super-allergen filled cat or something?
I'm no doctor, but from what I remember from the days when I had to get allergy shots twice a month, it goes something like this...
You are allergic to the saliva and/or dander (not so much the dander as the general public thinks--so my doctor said) If you don't have the immunities to that particular cat's chemistry, you will have reactions. Therefore, if it's a recent addition, you will be allergic to it until you develop antibodies or histamines or maybe it's anti-histamines--like I said, I'm no doctor, if you develop them at all. Some people are just allergic, but it sounds like you are just allergic for now...
Then again, I could be totally talking out of my a--

But, I think that's the gist of what I was told...
