Why is my rabbit's pee dark or black? Is this normal for rabbits?

Hello there! Rabbit urine can be a rainbow of colors and still be normal. Rabbits excrete a large amount of minerals in their urine, like calcium, which can be whitish in color. Their urine also changes color based on what they eat - for example, a rabbit that eats a lot of carrot or sweet potato in a day will have dark orange colored urine. Milky white urine is probably nothing to worry about, but if Blacky is exhibiting any other symptoms (like anorexia or diarrhea), or you see any mucous-like substances or red streaking (potentially blood) in the urine, be sure to visit your vet right away. I hope this helps, and good luck with Blacky!

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.

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.

Hello, and thank you for your question. Bunny urine usually oxidizes the longer it is exposed to air, so it is normal for it to turn a shade of orange-pink as in the photo. However, if you notice she is urinating in unusual spots, or if she is acting off or eating or pooping less, then I would recommend seeking veterinary attention. It may be related to a urinary tract infection, bladder stones or crystals. In the meantime, ensure that Rose drinks plenty of water which will keep her urinating and flushing out any infection or crystals out of her bladder. You can do this by providing her usual green leafy veggies soaked in water for a few minutes before giving them to her. I hope this helps, and that Rose is well!

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. It is very normal for rabbits to have "milky urine" as they excrete a significant amount of calcium in their urine. It is also not unusual for their urine to be red-tinged, as a result of the porphyrins and plant pigments they excrete in their urine. I hope this is helpful!

Rabbit urine can be naturally more of an orange color than other mammals. This is partly due to their diet and partly their biology. If Olaf's urine is normally more yellowish than this and remains this color when you stop giving him medication and extra fruit (which is high in sugar so generally only given as a special treat), I would discuss this with your veterinarian. One way you can monitor urine color in rabbits who are litter box trained is to switch to white CareFresh litter, which will allow you to see the urine color more clearly than most other litter types. I hope this was helpful!

It's solid but very dark, this could be either due to something he ate or due to bleeding from the stomach. if this stays the same for another few days it would be a good idea to get it checked bu your vet.
