Debbi, It's entirely possible that you're allergic to your ferrets. Many of those symptoms could indicate asthma. (Breathing difficulty, dizziness, fatigue). You don't have to wheeze to have asthma. I became a ferret owner because I'm severely allergic to cats. When I have an asthma attack, I get those symptoms. I'm not as allergic to my ferrets, but I notice it if I go to a ferret shelther or show and stay longer than 30 minutes. I also noticed that it gets bad when I bathe them. (I've stopped doing that!)I have 4 ferrets and after adding each one I had an adjustment period. That's one reason I've stopped at 4. Do you feel the symptoms when you're away from home for a period. For example, are you working or in class for most of the day? Maybe you could board the ferrets for a week and see if you notice any difference. I hope this helps. Jeannette [Posted in FML issue 3154]
