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?
