Yes, I think Rose is right. It's mostlikely "red urine". Usually said to be harmless, I've noticedit in our rabbits when their urine is very concentrated when they maybe ill and not drinking enough. I'd push some pedialyte andNutri Cal or Critical Care for herbivores.
My aunt said that she say some reddish stuff inthe back of the hutch and they thought that maybe shemiscarried because they thought she might be pregnat and iremembered seeing this so do you think its just pee? ThanksRobert
