Yes! I have three girls, all sisters and am allergic to one far more than the others. I had them a year before it started aswell! Where her fur touched my bare skin would bring me out in a rash, and I rubbed some fur into my eye by accident and it reacted aswell. I may get a tiny bit of a reaction from the others, and sometimes the hay until I found one I don't react to. but Cookies fur gave me asthma reactions! It feels like a different texture to her sisters, so maybe that has something to do with it. Like my friends cat gave me an asthmatic reaction, but my mums cat doesn't, she just makes my nose run!
I weaned myself off daily anti histamines to try and let my body deal with the reactions and they have got much milder recently thankfully and I am careful to not get her fur on my clothes.
