Why Does Rabbit Pee Smell So Bad? [Preventing The Odor]

HomeHealthWhy Does Rabbit Pee Smell So Bad?

Rabbit urine smells bad because of the high levels of ammonia it contains. Ammonia is a strong-smelling gas that can stink up an entire house. Placing the rabbit hutch in a well-ventilated room will reduce the strong scent of rabbit urine.

If you have ever been near a rabbit cage that has not been cleaned out in a while, the odor can be pretty overwhelming. But why does rabbit pee smell so bad?

Rabbit urine is loaded with ammonia, which is highly concentrated and very smelly. The more rabbits there are in one area, the more potent the ammonia odor will be. Not only is the strong ammonia odor unpleasant for people, but it can be harmful to your rabbit’s health if they are exposed to too much of it.

You can do several things to help control the odor of rabbit urine, such as regular cage cleanings, using a litter box, and keeping your rabbit’s diet healthy.

In this post, we will dive into the science of why rabbit urine smells so bad, what you can do about it, and when you should see a vet.

The Science Behind Why Rabbit Pee Smells So Bad

The main reason rabbit urine smells so bad is because of the high levels of ammonia it contains. Ammonia is a gas that is produced when rabbits urinate.

Ammonia has a strong, pungent smell that can be very overwhelming. When rabbit urine combines with the ammonia in their waste, it can create an incredibly strong odor.

Rabbit urine also contains uric acid, a waste product produced when the body breaks down food.

The combination of ammonia and uric acid gives rabbit urine its strong, pungent smell.

Medical Issues That Can Cause Rabbit Urine to Smell Worse

Several medical conditions can cause a rabbit’s urine to smell worse.

Urinary Tract Infections

Urinary tract infections (UTIs) commonly cause strong-smelling urine in rabbits. UTIs occur when bacteria enters the urinary tract and cause an infection.

UTIs are more common in female rabbits than in males. This is because their urethra (the tube that carries urine from the bladder to the outside of the body) is shorter, making it easier for bacteria to enter the urinary tract.

UTIs can cause various symptoms, including strong-smelling urine, difficulty urinating, and bloody urine. If your rabbit shows any of these symptoms, it’s important to take them to the vet immediately.

Encephalitozoon Cuniculi

Encephalitozoon cuniculi (EC) is a parasitic infection that can cause kidney damage and urinary tract infections in rabbits. EC is most commonly spread through contact with contaminated urine, so it’s important to keep your rabbit’s cage clean.

Symptoms of EC include strong-smelling urine, loss of appetite, weight loss, and increased thirst. EC can be treated with medication, but it’s crucial to catch it early.


Leptospirosis is a bacterial infection that can be spread through contact with contaminated urine. It is a severe infection that can be fatal if left untreated, so it’s important to be aware of the symptoms.

Symptoms of leptospirosis include strong-smelling urine, fever, loss of appetite, weight loss, and dehydration. If your rabbit shows any of these symptoms, it’s important to take them to the vet immediately.

Poor Diet Can Cause Strong Smelling Urine

Rabbits are very sensitive to changes in their diet, and a poor diet can cause strong-smelling urine. A diet high in sugar and carbohydrates can cause your rabbit’s urine to smell sweet.

A diet that is low in fiber can also cause strong-smelling urine. This is because rabbits need a high-fiber diet to stay healthy. A low-fiber diet will cause digestive issues. When we think of digestive issues, we automatically think of constipation or diarrhea, but digestive issues can also cause changes in the urine.

Male Rabbits Typically Have Stronger Urine Scent Than Females

Male rabbits typically have a more pungent urine scent than females. This is because they spray to mark their territory. When a male rabbit sprays, the urine will be more concentrated and have a stronger odor.

Females will also have a strong urine scent when they are in heat. This is because they are trying to attract mates. However, the scent of a female spray isn’t nearly as potent as a males.

How to Prevent Your House From Smelling Like Rabbit Urine

Owning a rabbit provides an unspeakable amount of joy. However, as all rabbit owners know, it also means living with the occasional strong urine smell.

There are several things you can do to prevent your house from smelling like rabbit urine:

Keep Your Rabbits Cage Clean

The easiest way to prevent your house from smelling like rabbit urine is to keep your rabbits cage clean. A clean cage will help to prevent bacteria and other organisms from multiplying and causing an even stronger odor.

Clean the cage at least once a week, and more often if necessary. Spot clean every day.

Train Your Rabbit to Use a Litter Box

Rabbits are naturally clean animals and can be easily trained to use a litter box. A litter box will help to keep your rabbit’s cage clean and free of urine and feces.

Litter training is relatively easy and can be done with various types of litter. The most important thing is to be consistent and patient.

Clean Any Accidents With a Vinegar Solution

Rabbits are animals, and accidents happen. If your rabbit has an accident outside its litter box or hutch, it’s important to clean it up immediately.

A vinegar solution is the best way to clean up a rabbit accident. Vinegar will neutralize the odor and help to prevent bacteria growth.

To make the vinegar solution:

  • Mix equal parts water and vinegar
  • Apply the solution to the affected area and let it sit for 5-10 minutes
  • Wipe the area clean with a paper towel or cloth

Feed Your Rabbit a Balanced Diet

A diet high in fiber and low in sugar and carbohydrates will help prevent strong-smelling urine. A diet that is high in fiber will also help to keep your rabbit’s digestive system healthy.

A good diet is important to keeping your rabbit healthy and happy. Talk to your veterinarian if you’re unsure what to feed your rabbit.

How to Get Rid of the Urine Smell in Your House

The above tips are great for preventing your house from smelling like rabbit urine, but what should you do if your house already smells like urine?

Ventilation In The Room Where the Cage is Located

If the room where your rabbits cage is located smells like urine, you need to increase ventilation. Open a window or door to let fresh air in.

Use an Air Purifier or Dehumidifier

An air purifier or dehumidifier can also help to remove the urine smell from the air. These devices work by filtering out airborne particles and absorbing moisture.

Consider Spaying or Neutering Your Rabbit

Spaying or neutering your rabbit will help to reduce the amount of urine they produce. This is because rabbits that aren’t fixed produce more urine to mark their territory.

When to See a Vet

It’s completely normal for rabbit urine to smell bad, so there’s no need to see a vet in most cases. However, if the urine smell is particularly strong or if you notice any other changes in your rabbit’s health, it’s always best to err on the side of caution and make an appointment with your vet. As previously mentioned, a few infections can cause the urine to smell even worse. It’s best to see a vet to rule out any medical issues.

The Downsides to Owning a Rabbit

There are a lot of benefits to owning a rabbit, but there are also a few downsides. One of the biggest negatives is the fact that rabbit urine smells terrible. However, there are several things you can do to prevent or get rid of the odor. The most important thing is to clean your rabbit’s cage, train them to use a litter box, and feed them a balanced diet. If the odor is particularly strong, you can also try increasing ventilation, using an air purifier or dehumidifier, or spaying or neutering your rabbit.
