Red rabbit urine isn’t always a cause for alarm. This blog post will be your guide to understanding the reasons behind your rabbit’s ruby red relief. We’ll learn the difference between normal pigment-induced coloration and signs that might indicate a deeper health concern. 

Learn what dietary factors can influence urine color, and discover the red flags that warrant a trip to the vet. So, grab your carrots, cozy up, and let’s navigate the sometimes-confusing world of rabbit pee.

Rabbit Urinary Process


Rabbits like most animals, remove waste products from their body through urine production. 


Filtration of Rabbit Urinary Process


The kidneys act as filters, constantly cleaning the blood. They remove waste products, like excess minerals and urea, while keeping important components like proteins and blood cells.

Transportation of Rabbit Urinary Process


The filtered waste products don’t stay in the kidneys. Thin tubes called ureters carry the urine away from each kidney down to the bladder.

Process of Rabbit Storing Urinary


The bladder acts as a reservoir. Urine collects here until the rabbit eliminates it from its body.

Elimination of Rabbit Urinary Process


The urethra is the final stop. This tube leads from the bladder to the outside of the body, allowing the rabbit to urinate and expel the waste.

Normal Causes For Why is My Rabbit’s Urine Red


Red urine in rabbits can be a cause for concern, but it’s not always a sign of trouble. Here’s a breakdown of why your rabbit’s pee might be red?

Red Urine from Rabbit’s Causes Plant Pigments


The culprit? Colorful vegetables like carrots, beets, broccoli, and cabbage. These veggies are packed with pigments like betalains and anthocyanins.

When your rabbit munches on these, the pigments are absorbed and then eliminated through the urine.

[The Good News] This discoloration usually happens within 24 hours of eating the veggies and is completely harmless.


Rabbit Urine is Red from Calcium Carbonate


Rabbit urine naturally has high calcium levels. These minerals can combine and form a sediment at the bottom of the litter box.

This sediment can appear reddish when wet. The red color comes from pigments the rabbit excretes along with the calcium.

When the sediment dries, it usually turns white or chalky. Observing this color change can help differentiate it from true blood in the urine.


Stress Makes Rabbit Urine Red


While less common, stress can also cause temporary red urine in rabbits. Factors like travel, new pets, loud noises, or excessive handling can trigger this.

The red coloration in this case is likely due to the release of pigments during the stress response. 


Concerning Causes Why is My Rabbit’s Blood in Urine 


Red urine in rabbits can be alarming, and while sometimes it’s due to harmless pigments from veggies, blood in the urine warrants a closer look. Here’s why your rabbit might have blood in its urine?

Urinary Tract Infection (UTI) Causes of Blood in Rabbit Urine


Bacteria invading the urinary system can irritate the bladder and urethra. This irritation can cause blood in the urine, along with:

  • Straining to urinate
  • Frequent urination
  • Cloudy urine
  • Foul odor

Bladder Stones (Urinary Calculi) Causes Blood in Rabbit Urine


These mineral deposits scrape the bladder lining, leading to blood in the urine. Watch for signs like:

  • Frequent urination
  • Discomfort while urinating
  • Blood clots

Hypercalciuria Causes Blood in Rabbit Urine


Hypercalciuria plays a big role here. It’s the excess excretion of calcium in the urine, creating a prime environment for stone formation.

Kidney Disease Causes Blood in Rabbits Urine


Advanced kidney damage can cause blood cells to leak into the urine. Thus showing the red color in urine.

Trauma Causes Blood in Rabbit Urine


Injuries to the urinary tract from falls or fights can also cause bleeding and show up as blood in the urine.

Uterine Issues Cause Blood in Rabbits Urine


Reddish discharge from your rabbit might not always be bloody urine. Reproductive issues, especially in unspayed females, can cause similar symptoms. 

Uterine tumors or thickening of the lining (uterine hyperplasia) can irritate the reproductive tract, leading to blood-tinged vaginal discharge. Miscarriage can also cause internal bleeding that shows up as a reddish discharge. 

Unlike urinary issues, these conditions might also present with abdominal swelling, lethargy, and a noticeable discharge from the genitals. If you suspect reproductive problems, consult a vet immediately for proper diagnosis and treatment.

[NOTE] If you notice red urine along with any of these symptoms, consult a veterinarian right away. They can determine the reason and suggest the best course of treatment. Early intervention is crucial for your rabbit’s health.

Diagnosis Of Blood in Rabbit Urine


While red urine can sometimes be caused by harmless pigments from veggies, it’s important to consult your veterinarian, especially if you notice other concerning symptoms. They can get to the bottom of the issue and recommend the best course of treatment.

The vet will likely start with a physical examination to check your rabbit’s overall health and look for signs of pain or discomfort. They’ll then likely recommend a urinalysis. This simple test analyzes the urine’s color, clarity, and presence of blood cells, bacteria, or other abnormalities. 

Depending on the findings, further tests might be needed. X-rays can reveal bladder stones or other abnormalities within the urinary system. Ultrasounds provide a detailed picture of the internal organs, including the bladder and kidneys. A cystoscopy might be needed in a few cases. This procedure uses a tiny camera to directly examine the inside of the bladder for abnormalities. 

By working together with your veterinarian and going through this diagnostic process, you can ensure your rabbit receives the proper care and gets back to hopping happily as soon as possible.

Treatment for Blood in Rabbit Urine


The treatment for your rabbit’s red urine will depend on the underlying cause diagnosed by your veterinarian. Here’s a general idea:

Treatment for UTIs Caused by Blood in Rabbit Urine


Antibiotics are the mainstay of treatment to clear the infection. Use the antibiotics prescribed by a veterinarian for your rabbit.

Treatment for Bladder Stones Due to Blood in Rabbit Urine


Depending on the size and location, stones might be managed with dietary changes or medication to dissolve them. In severe cases, surgery might be necessary for removal.

Treatment of Kidney Disease for Blood in Rabbit Urine


The treatment aims to manage symptoms and improve quality of life. This may involve dietary adjustments, medications to control blood pressure or manage fluids, and pain relief.

Treatment of Uterine Issues


Spaying is often recommended to prevent future problems. Depending on the severity, medications or surgery might be needed to address tumors or uterine hyperplasia.

Trauma Treatment for Blood in Rabbit Urine


Treatment depends on the extent of the injury. It might involve pain medication, antibiotics to prevent infection, and supportive care.

How to Prevent Blood in Rabbit Urine? 


While red urine can sometimes be unavoidable, there are steps you can take to promote good urinary health in your rabbit:



Hay should be the star of the show. It provides essential fiber for digestion and keeps your rabbit hydrated. Limit calcium-rich vegetables and alfalfa hay, which can contribute to bladder stones.



Fresh, clean water is vital. Ensure your rabbit has access to a water bottle and a bowl to encourage them to drink.


Litter Box Hygiene

A clean litter box reduces stress and encourages frequent urination. Clean the box daily and provide enough space for your rabbit to use it comfortably.


Regular Checkups


Schedule regular checkups with your veterinarian. These preventive visits can help identify any potential issues early on, leading to better outcomes.
