If you’re a proud rabbit owner, you may be wondering if your bunny is expecting a litter. Determining if your rabbit is pregnant can be tricky, but with a bit of know-how, you’ll be able to tell. In this comprehensive guide, we’ll walk you through all the signs, symptoms, and methods for determining if your rabbit is pregnant.

If you’re short on time, here’s a quick answer to your question: Look for signs of nesting behavior, enlarged or pink nipples, a plumper belly, and increased appetite around 10 to 14 days after breeding. An ultrasound and palpation by a vet can also confirm pregnancy.

Observing Changes in Behavior

When trying to determine if a rabbit is pregnant, one of the key factors to consider is changes in behavior. Rabbits, like many other animals, can exhibit certain behaviors that indicate they may be expecting.

By observing these changes, you can get a better idea of whether or not your rabbit is pregnant.

Increased Appetite

One common behavior change in pregnant rabbits is an increased appetite. If you notice that your rabbit is eating more than usual, it could be a sign that she is pregnant. Pregnant rabbits need to consume more nutrients to support the growth and development of their unborn kits.

Keep an eye out for your rabbit munching on her food more frequently or finishing her meals faster than usual.

Nesting Instinct

Another behavior to look out for is a nesting instinct. Pregnant rabbits often start to exhibit nesting behaviors as they prepare for the arrival of their kits. They may gather materials like straw, hay, or even their own fur to create a cozy and comfortable nest.

Keep an eye on your rabbit’s cage or enclosure for signs of nesting, such as rearranged bedding or a concentrated area where she spends a lot of time.

Territorial Aggression

Pregnant rabbits can also become more territorial and aggressive. This is especially true if they are expecting and have already started to build their nest. They may become more protective of their space and show signs of aggression towards other rabbits or even humans.

If you notice your rabbit displaying unusual aggression or guarding behavior, it could be a sign that she is pregnant and trying to protect her future offspring.

It’s important to note that behavior alone is not enough to confirm a rabbit’s pregnancy. Consulting a veterinarian is always the best option for an accurate diagnosis.

Physical Signs

When trying to determine if a rabbit is pregnant, there are several physical signs to look out for. These signs can help you determine if your rabbit is expecting and prepare you for the arrival of new baby bunnies. Here are some key physical signs to watch for:

Enlarged or Pink Nipples

One of the first signs of pregnancy in rabbits is the enlargement or pinkening of the nipples. As the pregnancy progresses, the hormone levels in the rabbit’s body change, causing the nipples to become larger and more prominent.

If you notice this change in your rabbit, it is a strong indication that she may be pregnant. However, it is important to note that not all rabbits show this sign, so it should be used in conjunction with other signs for a more accurate determination.

Heavier Body

Another physical sign of pregnancy in rabbits is a noticeable increase in body weight. As the baby bunnies grow inside the mother, her body will naturally become heavier. You may notice that your rabbit appears rounder or fuller in the belly area.

This weight gain is normal during pregnancy and is a good indicator that your rabbit is expecting.

Abdominal Palpation

Abdominal palpation is a technique that can be used to determine if a rabbit is pregnant. It involves gently feeling the rabbit’s abdomen to detect the presence of developing fetuses. This should be done by a veterinarian or an experienced rabbit breeder, as it requires a certain level of skill and knowledge.

By palpating the abdomen, the vet or breeder can feel for the presence of small, firm masses which indicate the presence of developing fetuses. This is a more accurate method of determining pregnancy, but it should be done with care to avoid causing any harm to the mother or the babies.

Remember, these physical signs are not foolproof and it is always best to consult with a veterinarian for a definitive diagnosis. They will be able to provide expert advice and guidance based on the individual case.

Confirming Pregnancy with a Vet

When it comes to determining whether a rabbit is pregnant, it is always best to consult with a veterinarian. Although there are some signs and symptoms that may indicate pregnancy, a vet can provide a definitive answer through various diagnostic methods.

Here are the three most common methods vets use to confirm rabbit pregnancies:

Blood Test

A blood test is one of the most accurate ways to confirm pregnancy in rabbits. It measures the hormone levels in the blood, specifically the hormone called relaxin, which is produced by the placenta. This hormone is only present during pregnancy, making it a reliable indicator.

A veterinarian will take a small blood sample from the rabbit and send it to a laboratory for analysis. The results usually come back within a few days, providing a clear answer on whether the rabbit is pregnant or not.


Another method commonly used by vets to confirm rabbit pregnancies is ultrasound. This non-invasive procedure uses sound waves to create images of the rabbit’s reproductive organs. By examining these images, a veterinarian can determine if there are developing fetuses in the uterus.

Ultrasound is safe for both the rabbit and her unborn babies, making it a popular choice for confirming pregnancy. It also allows the vet to estimate the number of babies and their gestational age.


Palpation, or feeling the rabbit’s abdomen, is another technique that veterinarians use to detect pregnancy. This method involves gently pressing and manipulating the rabbit’s belly to feel for the presence of growing fetuses.

However, palpation is not always reliable, especially during the early stages of pregnancy when the babies are small and difficult to detect. It is usually recommended to combine palpation with other diagnostic methods for a more accurate confirmation.

Remember, it is important to consult with a qualified veterinarian to confirm whether your rabbit is pregnant. They have the expertise and resources to provide an accurate diagnosis, ensuring the best care for both the mother and her babies.

Gestation Timeline

Knowing the gestation timeline of a rabbit is crucial when trying to determine if it is pregnant. Here is a complete guide to help you understand the different stages of pregnancy in rabbits.


The first step in determining if a rabbit is pregnant is to understand the breeding process. Rabbits are known for their rapid reproductive capabilities, with gestation periods lasting an average of 31 to 33 days. However, the exact duration can vary slightly depending on the breed.

It is important to note that rabbits can become pregnant soon after giving birth. Therefore, if you have a female rabbit and a male rabbit in the same enclosure, it is essential to separate them to avoid unplanned pregnancies.

Early Signs

During the early stages of pregnancy, it can be challenging to determine if a rabbit is pregnant. However, there are a few signs you can look out for. These include changes in behavior, such as nesting behavior or increased aggression.

Additionally, you may notice a slight increase in appetite and weight gain.

It is important to remember that these signs are not foolproof and may vary from rabbit to rabbit. If you suspect your rabbit may be pregnant, it is best to consult with a veterinarian for a definitive diagnosis.


As the pregnancy progresses, there are more noticeable changes in the rabbit’s physical appearance. Around the 14th to 18th day of gestation, you may be able to feel small lumps or bumps in the rabbit’s abdomen. This is due to the developing fetuses.

During this stage, it is crucial to provide the pregnant rabbit with a comfortable and quiet environment. Make sure to provide plenty of nesting materials, such as straw or shredded paper, to support the rabbit’s natural nesting instincts.

Late Pregnancy

In the final stages of pregnancy, the rabbit’s belly will become noticeably larger. You may also feel movement from the developing kits (baby rabbits) if you gently place your hand on the rabbit’s abdomen.

It is essential to provide the pregnant rabbit with a balanced diet during this stage to support the growth of the kits. Consult with a veterinarian for specific dietary recommendations.


Kindling refers to the process of giving birth in rabbits. It typically occurs around day 31 to 33 of gestation. Before kindling, the pregnant rabbit may exhibit nesting behavior and create a burrow or nest box to give birth in.

During this time, it is essential to create a quiet and stress-free environment for the rabbit. Avoid disturbing the nest box as much as possible to prevent unnecessary stress.

It is important to note that if you suspect your rabbit is pregnant but does not show any signs of kindling after the expected gestation period, it is best to consult with a veterinarian for further evaluation.

Remember, determining if a rabbit is pregnant can be challenging, and it is always best to seek professional advice from a veterinarian. They can perform a thorough examination and provide appropriate care for the pregnant rabbit and her kits.


Determining if your rabbit is expecting kits takes a bit of patience and observation. By keeping an eye out for changes in appetite, nesting behaviors, nipples, and body shape, you’ll be able to make an educated guess.

To confirm pregnancy, make an appointment with your vet for an ultrasound, palpation, or blood test. With the information in this guide, you’ll be able to tell if your bunny has a bundle of joy on the way!
