Cat Allergies Treatment

I am allergic to cats

By best I mean the strongest. And I don’t need an explanation for what I’m allergic to. I know already.

going to visit and they have a cat is there anything i can take ?

I’m staying at my girlfriends house for a week and a half and she has 2 cats. I have minor allergies…runny rose, itchy eyes, etc.

my brother is allergic to cats and we really want one, so what medicine could he take to treat his allergies?

I have allergies towards cats, and i am going to work at the ASPCA, and i want to know if there is any medicine i can take to help with my cat allergies. It can be over the counter or by perscription. I just want some ideas. Thanks.
I have asthma and i use my medicine for that. But i just want soemthing to stop my watery eyes and difficulty breathing and runny nose.
