Yesterday after holding my piggies (very briefly) my one arm broke out in a rash that was a bunch of small red dots. I am allergic so I didn't really think much about it. They went away after about 30 minutes. Just now, after only petting them a few times i have 3 dots...very itchy and about the size of the 'o's in this font. Could they possibly be mites and not an allergic reaction?
