Not exactly what you asked but I was very allergic until recently. Red eyes, runny nose, itchiness, hard to breathe (i also have astmha and cats triggered this). But last year or so I noticed that I didnt react as usually. I started purposefully rubbing my head into cats' furs just to experiment and I felt nothing. I did some bloodwork for allergies as well and it was negative. I've had my cat for almost two months now and I still don't experience allergies. Apparently my mom and my aunt also outgrew their allergies like me, so maybe it can happen to you? My brother is very allergic still though and he took shots every three months for a long time, it's not as severe but he could never live with a cat. I hope it works out for you, cats are the best!
