I'm sure Tucson is just as bad as Phoenix, because both my husband & I have been suffering since Feburary! Both of us are allergic to cats, and we have 3. One word: Flonase. That is all I can tell you! The Doctor gave it to both of us this year, and I swear it works!! We still have attacks, but they are very few and far between and we are able to keep the doors & windows open AND snuggle with the cats at night. Hang in there though, because it doesn't work overnight, but in time you will see a difference.

Good luck!
