Bunnies are known for their large eyes and twitchy noses. Their eyes often seem to be open even when they are sleeping or resting. This leads many bunny owners to wonder – do bunnies actually sleep with their eyes open?

If you’re short on time, here’s a quick answer: Yes, bunnies do often sleep with their eyes at least partially open. This is normal rabbit behavior.

In this comprehensive guide, we’ll cover why rabbits sleep with open eyes, whether their eyes are fully open or partially closed, the different sleep cycles of rabbits, and tips for identifying when your bunny is asleep.

Why Do Rabbits Sleep with Their Eyes Open?

Rabbits are fascinating creatures, known for their cute appearance and unique behaviors. One behavior that often surprises people is the fact that rabbits sleep with their eyes open. This may seem unusual to us, as humans typically close our eyes when we sleep.

However, there are several reasons why rabbits have evolved to sleep with their eyes open.

Prey Animals Stay Alert

Rabbits are prey animals, which means they are constantly on alert for potential predators. Sleeping with their eyes open allows them to stay vigilant even while they rest. By keeping their eyes open, rabbits can quickly detect any signs of danger and react accordingly.

This behavior has been essential for their survival in the wild.

Light Sleep Allowed for Vigilance

Another reason why rabbits sleep with their eyes open is that they enter a state of light sleep. Unlike humans, who experience deep REM sleep, rabbits need to be able to wake up quickly if a threat arises.

By sleeping with their eyes open, rabbits can easily transition between sleep and wakefulness, ensuring they are always ready to protect themselves.

Eyes Protected from Drying Out

Rabbits have a unique adaptation that allows them to sleep with their eyes open without experiencing dryness or discomfort. They have a special membrane called the nictitating membrane, which covers their eyes while they sleep.

This membrane keeps the eyes moist and protected, preventing them from drying out.

Are Bunny Eyes Fully Open During Sleep?

Have you ever wondered if bunnies sleep with their eyes open? It’s a common question among bunny owners and enthusiasts. While it may seem strange, the answer is no – bunnies do not sleep with their eyes fully open. Let’s dive into the fascinating world of bunny sleep habits to understand why.

Eyes Are Partially Closed

During sleep, bunnies close their eyes partially. This is similar to how humans and many other animals sleep. Just like us, bunnies need a good night’s sleep to stay healthy and alert. By partially closing their eyes, bunnies can relax and rest without completely exposing their eyes to the environment.

Inner Eyelid Closes

In addition to partially closing their eyes, bunnies have an inner eyelid called the nictitating membrane. This translucent membrane acts as a protective layer, covering the eye while still allowing some visibility.

It helps shield their delicate eyes from dust, debris, and other potential irritants while they sleep.

The nictitating membrane is not unique to bunnies – many animals, including birds, reptiles, and even some mammals, have this extra layer of protection. It serves as a natural defense mechanism, ensuring the eyes remain safe and comfortable during sleep.

Eye Movement Differs in Sleep

While bunnies don’t sleep with their eyes fully open, their eye movements during sleep differ from humans. Humans experience rapid eye movement (REM) sleep, which is associated with dreaming. In contrast, bunnies do not have REM sleep. Instead, they have a unique sleep pattern called “quiet sleep.”

During quiet sleep, bunnies have a relaxed and peaceful state, with minimal movement and muscle activity. Their eyes may appear calm and still, but they are not fully open. This sleep phase allows bunnies to conserve energy, repair their bodies, and rejuvenate for the next day’s activities.

So, next time you catch your bunny snoozing, take a closer look. You’ll see their eyes partially closed, indicating a state of restful sleep. Remember to provide a comfortable and quiet environment for your bunny to ensure they get the quality sleep they need for a happy and healthy life.

Different Stages of Rabbit Sleep

Just like humans and many other animals, rabbits also go through different stages of sleep. Understanding these stages can help you better understand your furry friend’s sleeping habits and behavior. Let’s take a closer look at the three main stages of rabbit sleep: light sleep, deep sleep, and REM sleep.

Light Sleep

During the light sleep stage, bunnies are in a state of relaxation but are still somewhat alert. Their muscles may be slightly tense, and they may twitch or move their ears in response to external stimuli.

It is during this stage that rabbits may sleep with their eyes open, giving them the appearance of being awake. This behavior is a natural defense mechanism that allows them to quickly react to potential threats in their environment.

However, it is important to note that not all rabbits sleep with their eyes open, and some may close their eyes completely during light sleep.

Deep Sleep

Deep sleep is the stage where rabbits experience their most restful sleep. During this stage, their muscles relax completely, and their breathing becomes slow and regular. Bunnies in deep sleep are less likely to be disturbed by external stimuli and may appear completely still.

It is important to create a peaceful and quiet sleeping environment for your rabbit during this stage to ensure they get the rest they need.

REM Sleep

REM sleep, which stands for Rapid Eye Movement, is the stage where rabbits experience intense brain activity and vivid dreams. During this stage, their eyes may move rapidly under their closed eyelids. REM sleep is crucial for the brain’s cognitive functions and plays a role in memory consolidation.

While rabbits do experience REM sleep, it is not as prominent as in humans or other mammals. They spend less time in this stage compared to other animals.

Understanding the different stages of rabbit sleep can help you provide a comfortable and suitable sleeping environment for your bunny. Remember that each rabbit may have slightly different sleep patterns, and it is essential to observe and understand your pet’s individual needs.

If you have any concerns about your rabbit’s sleep habits, it is always a good idea to consult with a veterinarian.

How to Tell if Your Rabbit is Asleep

As a rabbit owner, you may have wondered if your fluffy friend sleeps with their eyes open. While it may seem unusual, rabbits are known for their unique sleeping habits. Here are some ways to determine if your rabbit is fast asleep:

Breathing Slows Down

One of the first signs that your rabbit is asleep is a noticeable decrease in their breathing rate. When rabbits are awake, they tend to have rapid and shallow breaths. However, when they are in a deep sleep, their breathing becomes slow and steady.

Less Movement

Another indication that your rabbit is asleep is a decrease in their overall movement. When awake, rabbits are known for their energetic and playful behavior. But when they are asleep, they tend to be more still and relaxed. Keep an eye out for a lack of hopping, running or exploring.

Don’t React to Sounds

Rabbits have excellent hearing and are usually quick to react to any sound or movement in their surroundings. However, when they are in a deep sleep, they become less responsive to external stimuli. If your rabbit remains undisturbed even when there are loud noises or sudden movements, it’s a good sign that they are fast asleep.

Eyes Glaze Over

Contrary to popular belief, rabbits do not sleep with their eyes open. When rabbits are asleep, their eyes will actually glaze over, giving them a dreamy appearance. This is because their eyelids partially close and cover their eyes, providing them with some protection while they rest.

So, if your rabbit’s eyes are glazed over, you can be sure that they are catching some Z’s.

Remember, rabbits have different sleep patterns compared to humans. They are crepuscular animals, which means they are most active during dawn and dusk. Additionally, rabbits have short periods of deep sleep throughout the day, interspersed with periods of light sleep.

Understanding your rabbit’s sleeping habits will help you provide them with a comfortable and safe sleeping environment.

Tips for Rabbit Sleep

Provide Comfortable Bedding

Creating a cozy and comfortable sleeping environment is essential for rabbits to get a good night’s rest. When it comes to bedding, opt for materials that are soft, absorbent, and safe for your furry friend.

Popular choices include hay, straw, or specially designed bedding made from recycled paper or wood fibers. Make sure to avoid using bedding made from cedar or pine, as the strong scent can be harmful to rabbits’ respiratory systems.

Give Them a Safe Space

Rabbits are prey animals, and they need a safe and secure space to feel at ease while sleeping. Providing them with a dedicated sleeping area, such as a cozy hutch or a quiet corner of their enclosure, can help them feel protected and reduce stress.

Make sure the sleeping space is well-ventilated, free from drafts, and away from loud noises or bright lights that can disturb their sleep.

Follow a Schedule

Establishing a consistent sleep schedule can benefit rabbits by helping them regulate their internal body clock. These adorable creatures are crepuscular, which means they are most active during dawn and dusk.

By aligning their sleep schedule with these natural instincts, you can ensure that they get enough rest. Try to maintain a routine by providing a quiet and undisturbed sleeping environment during the day while allowing them to explore and play in the early morning and evening.

Check for Health Issues

It’s important to keep a close eye on your rabbit’s sleeping habits for any signs of potential health issues. While it’s normal for rabbits to sleep with their eyes open, excessive sleepiness, lethargy, or changes in sleep patterns could be indicators of underlying problems.

If you notice any unusual behavior, it’s best to consult with a veterinarian who specializes in rabbit care. They can provide proper guidance and address any health concerns your bunny might have.

Remember, a well-rested rabbit is a happy and healthy rabbit. By implementing these tips and ensuring a comfortable and safe sleep environment, you can help your furry friend get the sleep they need for optimal health and well-being.


While it may look like bunnies sleep with their eyes wide open, they actually only keep their eyes partially open and their inner eyelids closed to stay protected as they rest. Understanding rabbit sleep cycles and patterns can help you ensure your bunny is getting the sleep they need.

By providing a proper environment and following healthy care practices, you can help your rabbit get the best quality sleep – even with their eyes open!
