My rat, Sagira, has been sneezing and she has watery eyes. Not the red watery eyes, just watery eyes. Other than that she has been completely fine. She's been eating, drinking, pooping, playing, and all of the things. I did just put down her sister and cagemate today do to cancer in her uterus, but I don't think it has anything to do with her sneezing. I use aspen bedding as I have since I got her, and she's about a year four months old.
