Why is my rabbit peeing brown? Is this a serious health concern?

Normal rabbit urine often reflects their diet and comes in many colors of red-orange-yellow and is not of major concern unless there are obvious blood clots, discomfort when urinating or altered thirst/fever.

Your rabbit has likely got a case of cystitis which is bladder inflammation. If you go to tge vet they can give you antibiotics and antinflammatories to treat it. If it has been going on a while there is a chance that infection has gone up to the kidneys which is more serious.

Hello. What you are seeing are porphyrin pigments in the urine. This is perfectly normal & may come & go. Make sure his pelleted diet is fresh & appropriate for rabbits. Rabbits absolutely need hay & grasses to live well & should be available to Snow all day long. You can feed other green leafy plants such as broccoli, cabbage, chard, parsley, celery leaves, watercress, kale, endive & carrot & beet tops.

This urine color could be normal, as rabbits can have red/orange urine due to the extretion of plant pigments within the diet. It's also possible it could be caused by a medical illness such as stones/sludge within the urinary tract, cystitis, uterine adencarcinoma, or polyps. Even though it often turns out that the color of the urine is normal due to the excretion of plant pigments, it's still important to have Waffles (love his name!) checked out by a vet to be sure. I would bring him into the vet in the morning for a health check.

I have not seen urine change this color due to eating banana skin but it is possible, since the pigments in different foods can affect the color of urine and fecal pellets. I would watch him carefully and if this urine color continues have a rabbit vet examine him, take abdominal xrays, and do a urine test to make sure he doesn't have bladder stones, a tumor, or some other condition causing bloody urine. Hope that helps!

It is possible your bunny has a urinary tract infection (red urine and urinary accidents can both be seen with this condition). Another possibility would be a bladder stone or tumor. Your bunny should see a veterinarian to check her urine, and start an antibiotic if needed or have an x-ray if no sign of infection is seen in the urine.

Thanks for reaching out about Snowbow and including a photo. Scratching at the ears could be ear mites or an infection. Take a look inside of the ear to see if any accumulations, discharge, odor, blood. The discolored urine could be due to increased vitamin intake (B vitamins will often change the color of the urine). But he could also have a urinary tract infection. A veterinary visit is recommended for both conditions. Good luck.
