My rabbit has rust-colored urine. Is it normal or cause for concern?

Hello, and thank you for your question. It's amazing to hear Rusty is almost 15! If all the foods you mentioned are regular items in his diet, it is unlikely that any of them are a cause for the orange urine. Sometimes if urine is left out to oxidize in air (i.e. he peed on the floor instead of in the litter box), it can turn a reddish-orange colour. If Rusty is otherwise acting, eating, and pooping normally, I would keep an eye on him for now. If any of these behaviours change, I would recommend taking him to the vet. They can test his urine sample for any evidence of abnormal crystals or bacteria, and also assess the concentration of his urine to ensure his kidneys are functioning normally. His diet seems just fine. The only thing I would be cautious of is not to feed spinach too often, which it doesn't seem like you are doing since it is in rotation with other veggies. Spinach in large quantities can cause calcium crystals to form in the urine. I hope this helps, and that Rusty is happy and healthy!

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.

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!

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 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!

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!
