Am I allergic to my cat?

I moved into a new house about half a year ago. Shortly after I got a cat I started to get stuffy noses and I sneeze a lot. I have trouble sleeping because it’s hard to breathe! I used to have an old cat at my other house and I didn’t have any of these symptoms. Could I be allergic to my new cat and not my old one?... show more I moved into a new house about half a year ago.

I used to have an old cat at my other house and I didn’t have any of these symptoms. Could I be allergic to my new cat and not my old one? Or could it have nothing to do with my old cat and something to do with the new house? I used to think it was the air conditioner, but now that that’s turned off and the heat is on, I’m still having the same symptoms. I really don’t want to get an allergy test but maybe I’ll have to. I’m just not sure what to do!
