It's most likely porphorin which is basically like mucus. If there's a lot it's not a good thing if combined with sneezing. If there's a lot throughout the day with sneezing, I'd make a vet appointment as soon you can so you can get medication to treat her.Hi! My young (I'm not sure of her precise age, but she is about 5 inches from nose to tail) albino feeder female ratty, Rosie, has a slightly bloody nose. She has been sneezing a lot lately. After her cagemate, Missy, died of pnemonia I sanitized her cage thouroughly. it's not much blood, it's just a little around the rim of her nose. Why was it bleeding though?
Don't panic. If you catch it early she will be fine . You can always private message me also with any other questions you have. I just got 2 rats a few months ago and have been dealing with porphorin as well as sneezing a lot.
