My sister and I both are having issues with our rats sneezing...a lot. Yoshi is the one in my group that is sneezing. I was wondering what I could give her to help her get over what ever illness she has. A man at a pet store recommended putting a fish antibacterial stuff in their water but that doesn't seem like it will help. Yoshi is 10 weeks old and I got her from the same pet store that my sister got hers (the two rats we believe are sisters)

None of my other rats are sneezing though they are all in the same room.
