Red urine or blood

Question
I have a 5 year old dwarf female rabbit, not spayed. About 2 weeks ago, she stopped eating pellets and would munch little hay and drink little water, and for about two days did not produce no stool and had a liquid discharge a every once in a while all day that looked like pee, I began feeding by hand pellets and give her a little more water. And making little massages on the tummy. Then she began producing stool, but still not eating pellet but eating hay and the discharge began ceasing . But all that she never look depressed, her behavior always been the same as normal. Now she is beginning to eat a little more and drinking more water but I seeing a red urine, it looks like blood. She has not been eating anything besides her normal food that could be causing the red stain. So now I am worried don't know what could be, she doesn't look like she's in pain.
I don't know if I explained that right but I hope you can advise me.
thank you

Answer
Dear Sandra,

You need to get her to a good rabbit vet immediately:

While urinary tract problems such as infection, bladder stone or sludge can cause blood in the urine, a much more likely cause in an unspayed female who's five years old is uterine cancer.  This would also explain her signs of illness/discomfort.

Please read:

www.rabbit.org/health/spay.html

Note that if this was caught in time, a spay could save her life and completely resolve the problem.  Most likely metastasis location is the lungs, so the vet might wish to take radiographs to be sure the cancer (if that's what she has) has not spread there.  If she does have a uterine adenocarcinoma, she should be spayed immediately.  The longer she bleeds, the worse she'll be as a surgical candidate.

I hope this helps.
