Give it six-eight weeks and you'll be free of allergies. Thats how long it took me, and I was properly wheezy around cats before being landed with one.
Now the little fucker tries his best to kill me by sitting on my head and I'm absolutely fine.
I'm the same, when I got Celeste I sneezed and sniffled a lot, now she's by my side pretty much the whole time I'm at home and it's fine, other than my skin being a bit itchy at times.
Ironically, after searching for a cat that my wife wouldn’t be allergic to, I think I am 😔
