Outer Anatomy


According to a BBC magazine article, rabbits’ ears have two roles that help your pet daily. One is to have a grasp on their surroundings and avoid predators; and second is to hear sounds like most species. Usually, the physical appearance of their ears is long and fluffy. But it can all depend on the breed of the rabbits.

Rabbit has a great sense of hearing. The BBC says your pet can pick up a sound as far as 3 kilometers from where they are standing. This feature helps them survive in the wild, such as finding food, mating, and avoiding other animals. 

However, you must understand that some issues can also occur in rabbit ears. One of them is ear mites. This type of parasitic infestation is a common problem that most pet owners experience. 


Rabbits naturally have a great vision of their surroundings. However, one of the disadvantages for your pet is the placement of their eyes. If you notice, both eyes of the rabbits are positioned on the opposite side of their head. That is why their front vision is deprived. 

Moreover, according to some reports, the rabbit’s eye is positioned near the molar roots. This is why some dental issues are interconnected in the eyes of rabbits. There is a higher risk of encountering issues in their eyes if you do not care about your pet’s oral health.  


The nose of the bunny is comparatively small. But their sense of smell works excellently. This function helps rabbits find food in their surroundings and avoid nearby predators. 

Moreover, the rabbit’s nasal is extremely receptive to fragrances, compounds, and particles. That is why your pet tends to be sensitive to its sense of smell. Factors like this can increase upper respiratory risks for rabbits. Too much fragrance is bad for them because it affects their inner system.


The teeth of the rabbit help them consume foods and turn them into small pieces for easy digestion. Rabbits are classified as herbivore animals. The design of their teeth is long and strong enough to consume grass and hay. It is important that you also maintain their teeth clean. Maintaining dental health in rabbits is considered a responsibility because it can cause extreme pain for your pet. 

The Supreme Pet Foods stated that rabbit teeth are continuously growing. One reason is to help them break down fiber-rich food every day. But this kind of condition can cause risks to their health, like overgrown teeth. Some studies say food is one of the contributing factors to why rabbit teeth experience problems. To avoid this, you can ask your trusted veterinarian what type of food benefits the oral health of your rabbit. 


A rabbit possesses four limbs. The two in the anterior are named the front limbs, and the two in the back are named the rear limbs. Furthermore, the fore pads are known as the forefeet, and the back pads are known as the hind feet. 

This helps your pet jump high and walk when hunting for food. Their legs are also built to have strong muscles, which is why it assists them in hopping from one position to another. According to Vet Explains report, a rabbit’s average height is two feet high; considering their body size, it is advantageous for your pet to jump at that distance. 

In addition, rabbit feet possess claws and are incorporated with fur and hair. Usually, the rear limbs are larger than the front limbs to serve in bouncing. Driving in the rear limbs is much more widespread than in the front limbs.


The fur and skin of bunnies possess some bizarre features. Their skin is delicate, and can be trimmed efficiently, and the fur is very compact and exquisite. That is why it is essential to groom your pet to avoid hair entanglement. Sometimes rabbits ingest some of their furs, which can trigger mild digestive problems.  

Inner Anatomy

Skeletal System

The bones that make up the skeleton of rabbits are considerably fragile compared to other pet animals, such as a dog. It would be best to place them in a safe shelter to avoid accidents that cause limb fractures. Rabbits’ bones help your pet build a good posture. It also helps them do their daily activity, such as walking, jumping, and exercising.

Like other species, bone is important to ensure safety and a stronger grip on the body. Your rabbit’s body comprises two different bone structures from the head up to the tail namely the compact bone and spongy bone. Each structure has a feature that helps build your pet’s body stronger. Allowing other body systems to work effectively.  

Muscular System

Like in some animals, the rabbit’s muscular system is regulated by your pet’s nervous system. It is one of the fundamental notions of any muscular system. Muscles function through electrical beacons within the brain and the body’s parts.

The vertebras of the backbone give comfort to the rear of the pet. Supposing this is supplemented by badly grown bone muscles and thorax muscles, the average stability of the bone formation and the biomechanics can be modified, which can drive a regressive mechanism.  

In addition, the National Institute of Arthritis and Musculoskeletal says that muscle’s primary role is to help your pet have movement control. For example, when jumping, the rabbit can stop and then jump again in the opposite direction. The core muscle helps them create a flawless motion whenever your pet tries to move. That is why it is also important to feed your healthy rabbit foods to benefit the rabbit in maintaining its muscle strength.      

Reproductive System

Male bunnies are called bucks, while female bunnies are named doe. Like in other species, female rabbits are responsible for creating litter. Caring for the babies until they are born. The reproductive system of the rabbit is important in reproduction. Each part is a contributing factor in making a healthy litter. 

However, there are many risks in rabbits regarding their reproductive system. That is why sometimes, veterinarians suggest spying on or neutering their rabbit while it is young. One of the common problems that rabbits can have is cancer and infection.  

Moreover, rabbits’ aggression sometimes comes from the hormones of the reproductive system. That is why when caring for more than one rabbit, you will notice a territorial claiming behavior because it is their nature and instinct to claim their place. 

To guide you better, here is the list of parts of a Rabbit’s Reproductive System.


The penis has a curved penile case and urethra. It is covered in rabbit skin and hangs freely outside of the abdomen part of your pet. The penis is the main passageway of sperm cells from the testes when mating with a female rabbit. It can start to grow in rabbits after 2 months old. 


The rabbit testicular is the one that produces hormones and sperm cells in male rabbits. The bunny has two gonads that sink at nearly 12 weeks. These gonads are huge with epididymal lipid pads. In the grown-up male, they rest in two virtually baldy scrotal pouches, which are cranial to the penis (in most of the placental animals, they rest dorsally to the penis). 


The female rabbit has a binary uterus. Unlike other animals, rabbits’ uterus work differently because they have two uterus horns. Hence, one disadvantage for your pet is that it is challenging for doctors to know if they have an infection or underlying illness. 

Rabbits’ uterus and testicles are prone to infection because of a bacteria called Pasteurella multocida. This is transferable from one rabbit to another rabbit through mating. That is why when you are planning to breed your pet, ensure that the mate is not a bacterial carrier. It can cause pyometra to your pet or also called a uterus infection. 

Digestive System

The rabbit’s digestive system is important in metabolizing their daily food intake. Aside from that, you must remember that it does not work the same as other animals like dogs or cats. That is because rabbit digestion is a one-way process. Meaning once food enters the month of the rabbits, their only way is to exit through poop.  

This is also the reason why rabbits are not capable of vomiting food. Physically and internally, their body is not suited to throw up because they don’t have a gag reflex and have a weak diaphragm. One disadvantage is when your pet accidentally eats a poison or toxin, complications will occur in its digestive system. Occasionally it results in diarrhea.

Going back, you might wonder how digestive functions work. Several parts of the digestive system work together to help your pet acquire the right nutrition and two waste materials. To guide you better, here are the primary parts of a rabbit’s digestive system:


Food goes through the mouth of your rabbit first. This is the first step in acquiring nutrients for your pet. When you offer them their regular diet, they eat the food and bite it into pieces so it can easily go through the other parts of the digestive system. 


The next step of the digestive process is traveling food through the esophagus. It is described as a long tunnel that helps your rabbit push the food in the stomach inside their body. 


The stomach is like the filter of food in your rabbit’s body. Its primary role is to dissolve the pieces of food into smaller measures so that the nutrients can travel easily to the other organs and part of your pet’s body. There is an acid inside the stomach of the rabbits. This acid helps break down the nutrients and sends them to the intestine for distribution. 


The rabbit intestine is divided into two primary parts. First is the small intestine, where the absorption of nutrients from food happens. And the second is the large intestine, where unwanted contents like starch or carbohydrates are stored.

Rectum and Anus

The last part of the digestive process happens in the rectum and anus. They are the ones who collect and make the structure of poop. All the unwanted compounds from the large intestine proceed to this digestion process.  

Cardiovascular System 

The cardiovascular system is where the heart and blood work of the rabbit belongs. It is interconnected with the respiratory system. Like in any species, taking care of your pet’s       respiratory health is important because the heart is one of the primary functions that keep your pet alive. According to the National Library of Medicine (NIH), good cardiovascular activity in rabbits prolongs their lifespan.

However, taking care of their respiratory health is also a challenge. The NIH added that many rabbits have been suffering from cardiovascular issues for the past years. That is because rabbits’ hearts are unique. Rabbits’ tricuspid valve is composed of only two parts rather than three. Hence, the arctic nerve of the heart is not connected to other artery parts in the body.   

Avoid exposure to chemical and toxin products to help your rabbit have good cardiovascular health. This will prevent your pet from acquiring problems and serious complications. For example, weed and its smoke are poisonous in rabbits, as well as some pesticides and chemicals used to kill insects and pests.
