Why is my rabbit's urine green after neutering? Is it normal?

Thanks for reaching out about Vasco. It is not uncommon for male rabbits to urinate on areas as territoriality marking. Castration is recommended in an attempt to curb this behavior, Works on most but not on all. The thicker, brown urine might be a result of testosterone but also too much green vegetables in the diet. Have a veterinarian review your rabbits diet. Good luck.

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, 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. 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 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!

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 am wondering if her urine is strongly concentrated. I have never seen green urine before but really concentrated yellow urine can have an odd appearance. The urine becomes more concentrated when a patient drinks less water or is dehydrated. I would recommend taking her and a urine sample to your vet to just make sure it is normal and she does not need supportive care like hydration. I hope that helps
