Why Rabbits Drink Their Own Urine

Rabbits drinking their own urine, known as coprophagy, is actually quite common behavior for domestic rabbits. There are several possible reasons why a rabbit may consume its own urine:

Lack of Water

One of the most common reasons rabbits drink their urine is due to a lack of available water. Rabbits have a relatively high need for water compared to some other pets. They require approximately 50-100 mL per kg of body weight per day. This means a typical 4 lb rabbit needs over 200 mL of water per day.

If fresh water is not always available, such as an empty water bottle, your rabbit may resort to drinking its urine to stay hydrated. Always ensure your rabbit has unlimited access to clean drinking water in a bottle or heavy ceramic bowl to prevent urine drinking.

Insufficient Nutrients

In some cases, rabbits may drink their urine if their diet is lacking essential nutrients. Rabbits are herbivores that require a diet high in fiber, relatively low in carbohydrates and calories, and with adequate protein.

If you are feeding a commercial pellet diet, choose one specifically formulated for rabbits with at least 18% crude fiber and between 14-19% crude protein. Also offer a constant supply of grass hay. Avoid diets too high in sugary fruits, vegetables, and treats. Feeding a nutritious rabbit-appropriate diet prevents urine drinking due to nutrient deficiencies.


Hormones can also influence some rabbit behaviors, including urine drinking. In unneutered male rabbits, the scent of urine contains pheromones that allow them to mark territory and attract mates. Intact males may drink their urine to better detect these chemical signals.

Spaying or neutering your rabbit is recommended to decrease these hormone-driven behaviors. At around 4-6 months of age, consider getting your rabbit sterilized by a rabbit-savvy veterinarian. This helps prevent unwanted litters and often reduces urine drinking driven by reproductive urges.


Stress can also cause rabbits to develop repetitive behaviors like drinking their own urine. Rabbits are prey animals by nature and can get anxious easily when frightened or feeling insecure. Some causes of stress include:

  • Lack of social bonding time with owners
  • Insufficient space or housing that lacks hiding spots
  • Loud noises
  • Sudden changes to environment or routine
  • Pain or illness

To minimize stress, dedicate at least 2-3 hours per day to letting your rabbit freely explore rabbit-proofed areas and interact with you. Provide a spacious cage or pen with areas to hide. Introduce changes gradually and use soothing voices and gentle handling when interacting with your rabbit. Bring your rabbit to a rabbit-experienced vet for regular wellness checks and if you notice symptoms of pain or illness.

Behavioral Problems

In some cases, urine drinking may stem from underlying behavioral issues. Rabbits that exhibit obsessive-compulsive tendencies can develop repetitive habits like consuming urine. Traumatic early weaning from the mother doe can also lead to this behavior later in life.

Consult with an experienced rabbit veterinarian or applied animal behaviorist if urine drinking seems driven by compulsion, anxiety, or trauma. Treatment may involve anti-anxiety medication, changes to diet and environment, or behavioral therapy. Intervening at the first signs can improve your rabbit's welfare.

In summary, the main reasons rabbits may drink their own urine include lack of water, insufficient diet, hormones, stress, and behavioral problems. By meeting your rabbit's needs and minimizing stress, as well as spaying/neutering, you can reduce urine drinking in pet rabbits. Consulting a vet is recommended if it becomes a chronic problem.

Will Drinking Urine Harm Rabbits?

Many rabbit owners naturally worry that drinking urine will make their bunny sick. In most cases, rabbits can consume their urine without any major health consequences. Here is some information on the effects urine drinking can have:

  • Dehydration: While urine provides some fluid, it cannot fully replace fresh clean water in a rabbit's diet. Relying solely on urine may lead to potentially dangerous dehydration in rabbits.

  • Poor nutrition: Urine has trace amounts of B vitamins and salts but does not contain other key nutrients rabbits need. Dietary deficiencies may develop over time if urine supplements their main diet.

  • Excess minerals: The high salt content of urine, while not immediately toxic, can potentially cause problems like bladder sludge or kidney stones with frequent consumption.

  • Bacteria: There is a low risk of bacterial infection from ingesting urine over time, as it is not sterile. This is especially true if the rabbit has a urinary tract infection.

  • Diarrhea: In some cases, the components of urine may irritate a rabbit's digestive tract or alter intestinal flora, leading to soft stools or diarrhea.

  • Bad habits: While not directly harmful, regular urine drinking can develop into an undesirable habit that is difficult to break.

  • No major toxicity: However, there are no acutely toxic compounds in healthy rabbit urine. Healthy kidneys filter out any waste products or toxins before excretion.

So in healthy rabbits, urine drinking does not usually cause immediate illness or toxicity. But over time, the indirect effects may lead to dehydration, nutritional imbalance, salt toxicity, bacterial issues, or diarrhea. Prevention is ideal to avoid associated health problems. Immediately contact your vet if your rabbit displays symptoms of a direct illness after ingesting urine.

How To Prevent Rabbits from Drinking Their Own Pee

If you notice your rabbit regularly consuming its urine, there are ways you can try preventing this behavior at home:

Change of Diet Plan

As mentioned, urine drinking can sometimes result from an insufficient diet. Evaluate if your rabbit's current diet meets all nutritional requirements:

  • Unlimited grass hay (Timothy, orchard, oat, Bermuda)

  • Limited pellets high in fiber and protein, low in carbohydrates

  • Reasonable quantities of vegetables (romaine, kale, parsley, cilantro, carrots, etc)

  • Occasional fruit treats (banana slices, apple chunks, strawberries)

  • Clean, fresh water always available in a bowl or bottle

Improving nutrition through an appropriate rabbit diet may diminish urine drinking driven by hunger or cravings. Gradually transition to new foods over 2-3 weeks.

Litter Training Your Rabbit

Another approach is litter training your rabbit, if not already done. Rabbits tend to consume urine in places where they frequently urinate. Litter training them to use a litter box can help minimize this temptation.

Place litter boxes with non-toxic litter in preferred urination corners. Gently return bunny to the box if catching them about to pee elsewhere. Praise and give a treat when they use the litter box correctly. Over time, litter training typically leads to less random urine that might be ingested.

In addition to diet and litter adjustments, also ensure your rabbit has:

  • Enough free-roaming time and social interaction to decrease stress

  • A comfortable, clean environment and hiding areas to feel secure

  • Toys and activities to prevent boredom related behaviors

  • Spay/neuter surgery to avoid urine drinking due to hormonal influences

Finally, if your rabbit starts displaying signs of illness after drinking its urine, schedule an appointment with your exotic vet right away to address any potential health issues. Stay alert to urine drinking and take steps to prevent it from becoming an ongoing problem. Your attentive care helps ensure your rabbit stays healthy while enjoying its natural behaviors.
