Why Is My Bunny Sleeping Too Much?

Has your rabbit suddenly started sleeping too much, and you are wondering what could be the possible reason for that?

Sleeping is normal for rabbits, but when it gets too much, it can be a cause for concern.

In this article, we will discuss in detail the common causes why your rabbits may suddenly start sleeping so much, potential health concerns, and much more.


Rabbits, unlike humans, are crepuscular creatures. This means they’re most active during the twilight hours of dawn and dusk.

During the day and night, rabbits tend to rest and sleep.

However, their sleep isn’t continuous like ours; they take numerous short naps, totaling about 6 to 8 hours of sleep per day.

Keep in mind that your bunny might not always close its eyes while sleeping. Rabbits can sleep with their eyes open to stay alert to potential predators.

If your rabbit is relaxed and comfortable in its surroundings, you may catch it sleeping with its eyes closed.

Factors That Influence a Rabbit’s Sleep Patterns

Several key factors can affect the sleep patterns of your bunny.

Let’s delve into these in more detail:

1. Age

As with many living beings, age plays a significant role in a rabbit’s sleep cycle. Baby rabbits or ‘kits’ grow rapidly and need more sleep than adult rabbits, much like human babies.

Similarly, as rabbits advance into their senior years, they may sleep more due to decreased overall energy levels or potential health problems accompanying old age.

On the other hand, adult rabbits in their prime years are generally more active and, therefore, may have less sleep time.

2. Health

Health is a crucial factor influencing the sleep patterns of a rabbit. Illness can often lead to increased sleep as the body tries to heal and recover.

Chronic conditions, like arthritis or dental issues, can make your bunny uncomfortable and disrupt its sleep.

Conversely, an illness may also cause a rabbit to sleep more, as it might feel lethargic and unwell.

3. Diet

The nutrition your rabbit receives greatly affects its energy levels and, subsequently, its sleep patterns. A balanced diet is vital for a rabbit’s overall health and well-being.

Bunnies primarily need high-quality hay, fresh vegetables, and small pellets. A diet lacking in essential nutrients can lead to lethargy and increased sleep.

Overfeeding, particularly with energy-dense but nutrient-poor foods, can also result in an overweight rabbit that sleeps more due to decreased energy levels.

4. Environment

Rabbits are sensitive to their surroundings. They prefer a quiet, safe, and comfortable environment for their sleep.

Environments with a lot of noise, commotion, or stress can lead to poor sleep quality or excessive sleep as a way to escape chaos.

Temperature can also influence sleep – if it’s too hot or cold, your rabbit may struggle to sleep comfortably.

Furthermore, the amount of light in the environment can influence a rabbit’s sleep-wake cycle, given their crepuscular nature.

5. Exercise

Physical activity plays a vital role in regulating a rabbit’s sleep. Regular exercise helps burn off energy, reduce stress, and promote better sleep.

A bunny that doesn’t get enough exercise may become restless and may either sleep poorly or sleep excessively to pass the time.

6. Social Interaction

Rabbits are social animals. They need interaction with their human family or bunny companions to stay mentally stimulated.

Lack of social interaction can lead to boredom and depression, which may result in excessive sleep.

Potential Health Concerns Related to Excessive Sleep

Rabbits are good at hiding their illnesses, a survival trait from their wild ancestors.

Excessive sleep or lethargy can sometimes be one of the few signs of an underlying health issue.

Let’s explain some of the potential health concerns that excessive sleep might indicate:

1. Lack of Stimulation

Rabbits are intelligent creatures that require regular physical and mental stimulation.

If a rabbit lacks enough activities to keep its mind and body active, it may sleep more simply due to boredom.

Long-term lack of stimulation can lead to behavioral problems and even depression, significantly affecting a rabbit’s quality of life.

2. Change in Routine

Rabbits thrive on routine. A sudden change in their daily schedule or environment, such as a move to a new home, can be stressful for a bunny, and it may respond by sleeping more than usual.

Other changes, like a new diet, a new family member, or the loss of a companion, can also disrupt a rabbit’s routine and lead to increased sleep.

3. Illness

As in humans, feeling unwell can make a rabbit sleep more than usual.

Various illnesses, from respiratory infections and gastrointestinal stasis to dental disease and parasites, can all lead to increased lethargy and sleep.

These illnesses often come with other symptoms, such as changes in appetite or bathroom habits, so keep a close eye on your bunny’s overall behavior and health.

4. Depression

Just like humans, rabbits can become depressed.

This can occur for various reasons, including losing a companion, chronic pain, a lack of stimulation, or major environmental changes.

A depressed rabbit may sleep more, eat less, be less interested in playtime, and generally be less active.

5. Obesity

If a rabbit is overfed and under-exercised, it may become obese.

Obesity in rabbits can lead to lethargy, excessive sleep, and various other health issues, such as heart disease and arthritis.

6. Pain

Pain is another crucial factor that could cause your bunny to sleep more.

Conditions like arthritis, dental disease, or injuries can cause your rabbit discomfort, making it less active and more likely to sleep or rest.


Here are some frequently asked questions.

Are Rabbits Meant To Sleep All Day?

Rabbits are naturally programmed to rest and conserve energy during the day, including napping, grooming, and other quiet activities.

This is normal behavior for rabbits and is not necessarily a cause for concern.

That being said, if you notice any changes in your rabbit’s sleeping patterns, such as excessive sleepiness, lethargy, or a lack of activity during their awake periods, it could be a sign of an underlying health issue.

How Do I Know When My Rabbit Is Sleeping?

Rabbits have several ways of showing that they are sleeping or resting.

Here are some signs that your rabbit may be sleeping:

1. Closed eyes: When rabbits sleep, they will be closed or partially closed. Although some rabbits may sleep with their eyes open, so this is not always a reliable indicator.

2. Lying down When rabbits sleep, they usually lie down on their side, with their legs tucked under their body.

3. Relaxed body: A sleeping rabbit will have a relaxed and limp body, with their muscles and limbs slack.

4. Slow breathing: A sleeping rabbit will have slow and shallow breathing, which may be difficult to observe unless you are close to them.

5. No movement: When rabbits sleep, they will not move around or respond to noises or activities around them.

Remember that rabbits can be easily startled and may wake up abruptly if they hear or sense anything unusual.

If you want to check on your rabbit while sleeping, approach them slowly and quietly to avoid startling them.

How Many Hours a Day Should a Rabbit Sleep?

The exact amount of sleep a rabbit needs can vary depending on age, activity level, and other factors; rabbits generally need around 8-10 hours of sleep each day.

Do Bunnies Sleep With Their Eyes Open?

Yes, rabbits can sleep with their eyes open, although it’s more common for rabbits to sleep with their eyes closed or partially closed.

When rabbits sleep with their eyes open, it’s typically because they are in a state of light sleep, where their bodies are still somewhat alert and aware of their surroundings.

In this state, rabbits may keep their eyes open to monitor their environment for potential threats or dangers.

Rabbits usually close their eyes and enter a deeper sleep when they feel safe and comfortable in their environment.

In this deeper state of sleep, rabbits typically lie down on their side or tuck their head under their body with their eyes closed or partially closed.


Numerous factors, including age, health, diet, and environment, can influence rabbit sleep patterns.

While some variation in sleep is normal, excessive sleep can indicate potential health concerns.

Promoting healthy sleep in rabbits involves a holistic approach, encompassing a balanced diet, plenty of exercises, and a comfortable living environment.
