I've been noticing that my littlest rat Amy has been sneezing a lot sense I brought her home. I've been watching her since last Friday (when I got her) and she sneezes quite a bit but nothing else seems to be wrong. She eats like a little piggy, jumps, plays, runs and even takes on Tara (who's twice her size but was her cage mate at the store) in frequent wrestling matches. She's a very talkative little girl too (which I love hehe). Do you think her sneezing is serious or could it just be a case of the sniffles?
