I am allergic to cats and I have two!! (just five months now) I don't get the sneezing/itchy eyes, but I get the wheezing and asthma. I have been experimenting with various meds under a doctor's care, and I think I finally have the right "cocktail". Flonase nasal spray, and Flovent, an inhaler. I feel WAY better, the wheezing has decreased dramatically.
At first I was on Singulair, but it didn't do a darn thing for me.
