I have a rabbit that came into my rescue about 1 month ago. She is an unspayed female and just about 2 weeks ago we notice vaginal bleeding. The only spot we keep seeing blood is in the litter box. We sent out a urine sample and their was not blood in the urine so that is why i am thinking it is vaginal bleeding. Has anyone every had this happen to a female and does it mean she has uterine cancer? please help.
