Well, let's see.... I'm allergic to fur and feathers... if it has either of those, then I am allergic to it. Feather's moreso than fur. Those are fairly mild and usually take long exposures to really effect me.

Side stories of note. On the peanut allergy, my friend's brother was allergic to nuts, like extremely, and went to a diner and got a chicken wrap, which unbeknownst to him, was cooked in peanut oil. Unfortunately, he passed away before the paramedics got there.

Also, My mother is chemical sensitive. Perfumes, scented anything, and she's deathly allergic. Been once or twice when she has been clinically dead due to students at her school being malicious and throwing cologne at her door. It is now considered attempted murder to do that there. She has gotten better in the last few years.
