I know I'm definetely allergic to amoxicillin. I believe that I'm allergic now to most animals, because whenever I meet a new animal I go into a sneezing fit. I've developed asthma since I first started college so it makes everything that much worse with the wheezing. I've developed some sort of tolerance to my cats but still get itchy eyes, sneezing, etc. when I pet them too long. Oh well, I love them.
