Sneezing, lethargy, mushy poops – as a rabbit owner, you monitor your bunny for these signs of illness. But what about your rabbit’s pee? Urine may seem like just a smelly mess to clean up, yet its color, consistency, and odor provide crucial clues into your rabbit’s health. Dehydration, infections, kidney issues, even cancer could be lurking inside those strange urine symptoms you’re ignoring. Don’t turn your nose up at the importance of proper pee! To understand the wide range of rabbit urine from normal to nasty, read our helpful guide breaking down all you need to know about your rabbit’s pee – the good, the bad, and the downright ugly. Your bunny’s health may depend on it!

What is a Healthy Rabbit Pee Color?

A rabbit's urine can come in a range of colors, from pale yellow to deep orange, and still be considered normal. The most common healthy urine color for a rabbit is a pale yellow. This indicates the rabbit is properly hydrated and fed. As long as the rabbit is energetic, eating and drinking normally, and does not seem in pain when urinating, a pale yellow urine is nothing to worry about.

If the urine becomes darker, it may indicate dehydration or a concentration of certain minerals. An orange or reddish tint often comes from plant pigments in vegetables the rabbit has eaten. This is not harmful. Dark brown urine can mean liver disease, while red urine may indicate blood. Bright yellow urine can result from excess calcium in the diet.

In an adult rabbit, the ideal urine color is a very pale yellow to straw yellow. This shows the urine is dilute and the rabbit is drinking enough water. Clear or colorless urine in an adult rabbit could signal over-hydration or kidney disease, diluting the urine too much.

Baby rabbits normally have darker yellow or orange urine up until 12 weeks old. Their developing kidneys are not able to concentrate the urine as much as an adult. As long as the kit is active and growing well, the urine color is nothing to be concerned about. Only if other symptoms appear should you consult a vet.

To keep your rabbit's pee a healthy pale yellow:

  • Provide unlimited timothy or grass hay
  • Give access to fresh water at all times
  • Feed a balanced diet of greens and limited pellets
  • Note urine color changes and contact a vet if concerned

With proper hydration and diet, your rabbit's pale yellow to straw colored urine indicates good urinary health.

My Rabbit’s Urine Comes Out as Sludge

If your rabbit's urine comes out thick, gritty, or toothpaste-like rather than as a liquid, this condition is known as sludge urine. There are a few possible causes for sludge urine:

  • Dehydration – Without enough fluid intake, the urine cannot dilute properly and becomes a thick sludge. Ensure unlimited access to clean water. Offer hydrating foods like cucumbers and watery veggies.

  • Kidney disease – Damaged or deteriorating kidneys cannot filter waste properly, leading to thick sludge urine. Kidney disease requires veterinary diagnosis and treatment.

  • Bladder sludge or stones – Mineral deposits or tiny stones in the bladder can create a sludge appearance. This requires treatment to clear the bladder and prevent recurring sludge.

  • Uterine infection (does) – A uterine infection in an unspayed female rabbit can spread bacteria to the bladder, causing sludge urine. Spaying is recommended.

  • Diet – Excess calcium from a diet too high in pellets or treats can lead to sludge. Feed a healthier diet with unlimited hay, greens, and limited pellets.

Sludge urine is uncomfortable for rabbits and can lead to dangerous blockages. Seek veterinary care if the sludge persists beyond 12-24 hours of home treatment. Providing extra fluids and hydrating foods may help temporary sludge pass. But an underlying condition needs diagnosis and treatment to prevent recurring sludge problems.

Does My Rabbit Have a UTI?

Urinary tract infections (UTIs) are common in rabbits, usually caused by bacteria entering the urinary system. Signs your rabbit may have a UTI include:

  • Urine that is cloudy, milky, or viscous
  • Urine with a strong ammonia odor
  • Straining or dribbling urine
  • Blood in the urine
  • Frequent urination of small amounts
  • Licking or irritation around the genitals
  • Changes in litter habits like not using the litter box

Your rabbit may also show general signs of illness like decreased appetite, lethargy, or sitting hunched up.

Bladder infections are most common in older, unneutered rabbits. Female rabbits are at higher risk due to their anatomy. But any rabbit can develop a UTI.

Diagnosing a UTI requires a veterinarian to take a urine sample for culture and analysis. They will prescribe antibiotic medication specifically targeted for the bacteria causing the infection. Relief should come within a few days of starting antibiotics. Be sure to finish the full course as directed to clear the infection entirely.

To help prevent UTIs:

  • Spay or neuter your rabbit to reduce hormones that encourage infections
  • Clean the litter box frequently to avoid bacteria build up
  • Give your rabbit lots of clean water and watery vegetables
  • Avoid sugary treats or foods high in calcium that irritate the urinary tract
  • Bring your rabbit for annual wellness checks to monitor kidney function

With proper treatment, most UTIs in rabbits resolve quickly and do not cause lasting damage. But left untreated, the infection can spread to the kidneys and become very dangerous. Contact your vet immediately if you notice any signs of an infection.

What Does Blood in Rabbit Urine Mean?

Seeing blood in your rabbit's urine can be very alarming. While it may look scary, a little blood is not necessarily an emergency. Possible causes of blood in rabbit urine include:

  • Urinary tract infection – Inflammation from a UTI can cause minor bleeding in the urinary tract. Antibiotics prescribed by a vet will clear up the infection and bleeding.

  • Bladder or kidney stones – Jagged crystals or stones tearing the lining of the bladder will cause bleeding. Stones may need surgical removal.

  • Cancer – Tumors in the bladder, urethra, or reproductive tract can bleed and lead to blood in the urine. This is more common in older rabbits (5+ years).

  • Trauma – A fall, bite, or other trauma to the abdomen can cause internal tears or injury that will bleed. Signs of pain, swelling, or external wounds indicate trauma.

  • Blood clotting problem – A genetic or acquired issue with the blood not clotting properly could cause spontaneous bleeding. Lab tests can diagnose clotting problems.

  • Uterine infection (does) – An infected uterus in an unspayed female rabbit may spread bacteria and inflammation to the bladder, causing bleeding during urination. Emergency spay surgery is required.

The severity of bleeding determines appropriate treatment. Mild bleeding may clear up with rest and medication. Heavy bleeding or clots require emergency veterinary care. Always contact your vet if you notice blood in your rabbit's urine, as the underlying cause needs to be determined. Prompt treatment greatly improves the outlook for your rabbit.

Why Does Rabbit Urine Smell So Bad?

While rabbit urine has a natural musky scent, an excessively strong ammonia odor is not normal. Some reasons why your rabbit's urine may have a very pungent smell include:

  • Bacteria – An overgrowth of harmful bacteria in the bladder or urine can create a foul ammonia smell. This usually signals a urinary tract infection needing antibiotic treatment.

  • Dehydration – Concentrated urine from lack of water intake smells stronger. Ensure unlimited fresh water. Give hydrating foods like cucumbers and watery veggies.

  • Diet – Diets too high in protein or calcium encourage bacterial growth and smelly urine. Feed a balanced diet of mostly hay with moderate greens and limited pellets.

  • Dirty cage – When urine and feces build up in the litter box or cage, ammonia gas is released. Clean the litter box daily and disinfect the cage regularly.

  • Kidney disease – Damaged kidneys cannot filter wastes properly, leading to stronger smelling urine concentrated with toxins. Requires veterinary diagnosis and care.

  • Tumors – Cancerous growths in the urinary tract, bladder, or reproductive organs can create abnormal urine with a very strong odor. Veterinary exam needed.

  • Abscess – An internal abscess leaked into the abdominal cavity can result in putrid smelling urine. Requires emergency surgery.

If simply cleaning the litter more frequently does not reduce your rabbit's urine odor, contact your vet. Pungent urine indicates an underlying medical problem needing treatment. Treating the condition will resolve the urine smell and give your rabbit relief.

Is Rabbit Urine Harmful to Humans?

In most cases, healthy rabbit urine poses no significant health risks to humans. However, there are some factors to be aware of regarding rabbit urine and human health:

  • Bacteria – Rabbit urine can contain harmful bacteria like E. coli that could cause illness if directly ingested or expose open wounds. Simple hygiene like hand washing minimizes risk.

  • Parasites – Rabbits can carry parasitic eggs in their urine, including E. cuniculi that can infect humans. This is rare, but another reason to wash hands after cleaning litter boxes.

  • Allergens – Proteins and dander in rabbit urine may trigger allergy symptoms in sensitive individuals. Wearing a mask when cleaning litter boxes can help.

  • Respiratory irritation – Ammonia gas from urine can irritate the eyes, nose and throat. Proper cage hygiene and ventilation reduces this effect.

  • Pregnancy – A rabbit illness called tularemia is of particular concern for pregnant women, due to risk of miscarriage from this bacteria. Wear gloves when handling sick rabbits.

  • Immune deficiency – People with already weakened immune systems are more susceptible to zoonotic illnesses carried in animal urine. Extra precautions should be taken.

While healthy rabbits themselves pose little health risk, proper hygiene when cleaning cages is always recommended. Wash hands thoroughly after handling animals or body fluids. Seek medical care if any severe symptoms develop after exposure to animal urine. With reasonable handling there should be no serious health effects.


In summary, normal rabbit urine can range from pale yellow to darker orange while still being considered healthy. Bright neon, dark brown, red, or cloudy urine requires veterinary attention. Ensure your rabbit stays hydrated with unlimited clean water and monitor litter habits for signs of infection or illness. While rabbit urine can have an ammonia odor, an excessively foul smell may indicate an underlying medical problem needing treatment. Overall, healthy rabbit urine is not seriously harmful to humans, but proper hygiene when cleaning cages is still advised. Keeping your rabbit's urinary system functioning properly promotes good health, quality of life, and normal urine for a happy, thriving rabbit.
