We have had a cat in our family for 15 years (1 for 12, now Zoey for 3). My husband is not a cat lover but gave in to my daughters. He tolerates the cat, but basicly they ignore each other. He says he used to be allergic cats -about 35 years ago. About a month ago he developed what we thought was a cold. He went to a walkin clinic last week and the dr. said yes he may have a sinus infection, but he thinks having a cat isn't helping. My husband proceeded to tell him that he always feels a little congested at home. When he goes out of town or is working outside he is fine, but when he comes home he feels cold like symptoms. The antibiotic and antihistamine that he was prescribed is not helping at all. Thursday he has an appt with the family dr. I'm so afraid he is going to say it's Zoey and then of course my husband will expect us to get rid of her. Any advice?? Can an allergy really come back after all these years. Zoey is not much of a shedder and short haired.
