I'm usually allergic to most cats. I just moved into a new place and one of my roommates has 2 of them. My allergies seeem to go on & off. For example, right now both have been sitting down at my feet for over an hour and I haven't sneezed or had a runny nose once. Other times though, I'll wake up at 4am and start sneezing like crazy, go through about 4 tissues, and go back to sleep. I have lived with my uncle before, with cat, and after several months my allergies just seemed to go away. Is this just something the body gets used to or is it on a case by case basis? On another note, should I just break down and see an ENT specialist? Thanks for any help.
