Why Rabbits Grind Their Teeth and Breathe Heavily During Sleep
Rabbits are Crepusculum so if you do see one, it most likely will be very early in the morning or very late at night. Most times while driving, you will see them run across the road in front of your car.
During the months of spring, you will see many of them running and skipping around the fields, annoying farmers whose crops they have nibbled on.
That's the habits of wild rabbits, so what are the habits of domestic rabbits? While farmers aren't fans of them, we humans adore the sight of a cute bunny rabbit with big ears and bright eyes who hops around the house.
Do you like Rabbits?
Now, if you are the owner of a bunny rabbit, you will notice some unusual things as the weeks progress. One of those things is the ability of your rabbit to sleep all hours of the day with their eyes opened. Not only that, but by the time early evening has drawn to a close, you might notice that someone is extremely eager to play or run around the house.
Any rabbit owner will notice this once you become active either in the early morning or the early hours of the night; guess who else will want to be get up and come out to play? Your rabbit.
If your rabbit is indoors, then the ability for them to move around freely will be extremely limited as you will most likely have them in a pen at night. If you have those pens with two levels, then they can run around as much as they like.
You can try to persuade your rabbit to sleep at night and be more active during the day, but since they are crepusculum animals, they going to be going against their natural instincts, so you're better off leaving nature alone.
Sleeping Patterns and Behaviour of Rabbits
The two things any rabbit owner needs to know about rabbits are:
- We refer to their sleep patterns as paradoxical sleep.
- The movement of their body while asleep is referred to as an atonic and myoclonic movement.
Rabbits are crepuscular animal which means that they are most active at dusk and dawn.
What Is Paradoxical Sleep?
We refer to the method a rabbit sleeps as paradoxical sleep patterns. What does this mean? Paradoxical sleep is actually a scientific term used to refer to the way a rabbit sleeps.
While it might seem to the human eye that a rabbit is in a deep sleep, any rabbit owner will notice how it will often notice how they wake up within a second if something disturbs it.
That's because, although the rabbit appears to be sound asleep, its brain is still sending out signals to the rest of the body in a way that's very active. This causes rapid eye movements, heavy breathing, and instant wakefulness in rabbits This is the stage of sleep when humans dream.
It's a kind of dreaming sleep that rabbits have.
What Is Atonic and Myoclonic Movement?
When rabbits are asleep, their bodies experience symptoms of atonic and myoclonic movement.
This means that their bodies will seem to become more fluid and flexible (atonic) while sleeping. They will also experience the symptoms of rapid eye movement and involuntary jerking (myoclonic movements) (Findlay & Hayward, 1968).
How Can You Tell If a Rabbit Is Sleeping?
It might seem hard to identify whether your rabbit is sleeping. Unlike most animals, they actually sleep with their eyes open. Confusing? I think so.
That is why rabbits need their own space. While it might seem like they are always on the run, they still need a timeout like us humans. They need a nice, quiet corner where they can head off to, for a bit of paradoxical sleep.
Rabbits sleep eight hours a day—but during the day as opposed to the night.
Sometimes, when you witness this action from a bunny rabbit, it might literally seem like it has lost the strength in its body, dropping instantly to the ground. This is a kind of atonic condition that the body experiences.
Your bunny will drop to the floor and end up many times lying on its side. This rapid movement can be quite alarming for new rabbit owners who haven't done research prior to getting a rabbit. Once you have witnessed this a few times, you will get used to it happening on a regular basis.
This type of behaviour is only carried out by rabbits who are very comfortable and extremely happy in their environment.
Just like cats, most rabbits are still alert to any little sound they hear while sleeping and they will immediately wake when they hear it. They will then spring up with ears raised and head up to see what the noise they heard is.
If your bunny is sitting beside you while you are on the couch and you are petting it on its head or under the chin, you might hear an odd sound. That sound is actually the bunny grinding its teeth together. You will feel the vibration on the chin/cheek area while petting it around the head. This is the rabbit's way of purring. It’s a sign it is extremely comfortable and happy in its surroundings. Plus, they love what you are doing to them.
Many times, your bunny rabbit can also drop off into its sleep this way and before you know it, you have a bunny rabbit with a body that jumps and a face that twitches.
If the noise is too loud and it doesn't seem like your bunny is making the sound out of contentment, it might have a problem with its teeth. This then needs to be checked out by the vet.
Sometimes, when the rabbit is sleeping, you might notice an odd head, cheek, or even full-body twitch. Your rabbit is actually having rabbit dreams. This is the myoclonic action coming into play when the rabbit is asleep.
You will witness the involuntary movements, and the best thing to do is to not touch it; leave them it and let them enjoy this quiet little nap.
