Is your rabbit sleeping...or just deep in thought? 

Sometimes, it’s hard to tell.

Because rabbits are prey animals, they often sleep with their eyes open — a survival instinct that helps them stay alert.

So why do they do this, and how can you tell if your bunny’s actually snoozing? Let’s take a closer look.

How a Rabbit’s Eyes Work

In addition to their top and bottom eyelids, bunnies have what’s called a third eyelid. It’s actually a thin, translucent membrane – called the nictitating membrane. This third eyelid is designed to keep their eyes lubricated and protect them from dirt and debris while keeping watch for predators.

Rabbits also have four tear glands – but only one tear duct opening, which means they blink far less than humans – sometimes as little as 12 times per hour. To put this in perspective, humans generally blink at least 15 times per minute!

Because of their complex eye design, rabbits are at risk for several eye problems. These include:

• Conjunctivitis: Pink eye is often a symptom of another issue, like bacterial or viral infections, ulcers, injuries, or a clogged tear duct.
• Abscesses: Bulging eyes commonly result from bacterial infections. Retrobulbar abscesses, however, occur behind the eye and are usually caused by dental problems.
• Eye ulcers: Open sores on your bunny’s cornea are typically caused by injuries, often just from scratching the eye on something.
• Tear duct obstruction:  This is usually linked to dental issues.
• Glaucoma: This painful eye condition and can cause blindness if left untreated. It’s especially common in New Zealand White rabbits.
• Cataracts: Cloudy eyes can lead to blindness.

If you notice any of the following symptoms, reach out to your rabbit-savvy veterinarian:

• Persistent conjunctivitis (pink eye)
• Constant eye rubbing
• Eye discharge or weeping
• Red eyes (looks like blood in the eyes)
• Different sized pupils
• Bulging eyes

How Rabbits Sleep

Especially during the day, rabbits sleep – but they tend to stay in non-rapid eye movement (NREM) sleep patterns. Studies have found that even though these rabbits look awake – with eyes open – their brain activity shows they’re in a light sleep state.

Certain animals, such as mammals and birds, exhibit a sleeping pattern known as NREM sleep or non-rapid eye movement. During NREM sleep, they may appear completely awake, but EEG readings show slow-wave brain activity, proving they’re actually dozing.

Sleeping with their eyes open keeps a rabbit’s light receptors active, allowing them to detect and respond to predators more quickly.

How to Tell if Your Rabbit is Sleeping

While your bunny may have her eyes open, there are other tell-tale signs to know if your rabbit is asleep:

• Slower or shallower breathing
• Little or no nose twitching
• Drooped or flattened ear position (if they are normally upright)
• Tucked into a “loaf” position, with paws underneath or laying down with extended legs
• Twitching paws, eyes, or whiskers
• Soft snoring sounds

How to Help Your Rabbit Sleep Better

While rabbits naturally sleep with their eyes open in the wild, pet rabbits may feel safe enough to sleep with their eyes closed. Here are a few ways to help your bun feel secure:

• Provide a spacious, secure environment with room to move, play, and explore.
• Offer safe hideouts where your rabbit can retreat if feeling overwhelmed or scared.

• Use soft, absorbent bedding like hay or fleece for comfort.

• Always supply fresh hay and water.

• Keep their space quiet and calm – some rabbits even relax with soft background music.

Your rabbit’s eyes are one of its most fascinating – and vulnerable – features. Understanding how they work, recognizing potential problems early, and providing a safe, comfortable environment will help your bunny stay healthy and well-rested. Keep an eye on your rabbit’s eyes and sleeping habits, and you’ll be doing your part to keep your furry friend happy and thriving!
