Everyone's body is different in terms of allergies. Some people will grow to tolerate their pets, other people will still have a problem. There are methods you can take to limit the amount of dander you breath in - Phoenix should NOT sleep on your pillow once she comes home, for example. She should have her own bed, and if possible, be kept out of your bedroom during the day, so she doesn't sleep on your bed. but do talk to your doctor. Some people get allergy shots and find is successful over the long term. Some people find they are okay with the help of allergy medication.

I, sadly, am not allowed to ever own a cat because my allergy is so severe. My sister had allergy shots of over ten years, and it did not diminish her cat reaction one bit, and her dog allergy just a little but wiped out her tree pollen allergies - it varies person to person.
