Couple days after getting my rat ruby I noticed lil bumps on the skin around my neck where she likes to spend most her time. I thought maybe it was just becoming irritated from her scratching when she crawls around, but yesterday she was crawling over my bare feet and now I have a red itchy bump on my foot. Do you think I may be allergic to rats, or does she have mites or bugs or something? She is going to the vet this weekend...
