Why does a rat chatter and grind its teeth?

Rat

03/07/2020 As a rule, experienced owners are well versed in the habits of pets. Beginners often become confused when they discover a strange habit in a decorative pet. Such “mysterious” manifestations that confuse the owner in domestic rats include chattering and grinding of teeth. The article explains why rodents do this, what such a habit means, and how to distinguish one manifestation from another.

At rest

Rodents' teeth constantly grow in length. Rats may grind their teeth to keep them at a reasonable and healthy length. If they didn't, their teeth would continue to grow indefinitely. Rat teeth that are too long can cause serious problems, especially difficulty chewing food.

Sometimes rats are simply born with misshapen teeth due to inbreeding, and they may have difficulty chewing and wearing down their teeth properly. In this case, the best way to keep your rat's teeth at normal length is to give them something to chew. Safe wood, rat pellets, and toys that allow rats to chew will naturally wear down their teeth to a safe length.

Prevention of bruxism

Even if you get rid of bruxism attacks during treatment, the disease may occur again. Therefore, for prevention, you should adhere to certain rules:

Make sure that your teeth are not clenched during the day, and stop yourself if you try to grind them.
Try to stick to your daily routine, play sports, and walk more in the fresh air.
Drink less strong tea and coffee.
When stressed, brew herbal soothing teas, for example, with mint, lemon balm or chamomile.

Monitor your health, visit a doctor for gastrointestinal diseases and other problems.
Try to expose yourself to less stress. It may be useful to visit a psychotherapist regularly to help you cope with difficult life circumstances.
Make sure your diet contains enough B vitamins, magnesium and calcium. You can consult your doctor to prescribe these microelements.

Excitement

If you hear your pet rat's teeth chattering extremely noisily, it could mean that something is making him nervous and upset. She may be bothered by something—perhaps the sound of someone hammering a nail into the wall in the next room.

Cats and larger animals hiding around her cage cause undue stress, as do loud noises. Rats have very sensitive hearing. Constant loud noises can cause anxiety in the animal. For us, even ordinary noise - for example, washing dishes - will seem very loud to the rat. Noises, especially loud ones, are terribly disturbing to rats.

You may upset your pet without even realizing it. A long list of common stress triggers in rats includes:

Loud unexpected sounds.
Changes in daily routine, including set feeding and play times.
Too much time alone.
New experiences such as veterinarian visits or road trips.
Presence of other potentially predatory animals or pets.
Too much time in the cage.
Small, unsanitary living quarters.
Low temperature and insufficient ventilation.
Too much bright light.
Excessive attention from people.
Being bullied by another rodent in the same cage.
Boredom and limitation of instincts.
Grief, for example, the loss of a close friend.

Stress isn't just about mental exhaustion in rats. It's also physically dangerous. A stressed pet often becomes susceptible to illness and disease.

Less common cases

Another option is that the rodent experiences joyful moments for some reason. This usually happens at the moment when the owner caresses his pet. The sound is equivalent to a cat purring. In case of particularly strong emotions, body vibration is added.

When you are scared or excited, you can hear a similar sound. However, these emotions are accompanied by characteristic behavior in everything else, so they are quite easy to read and distinguish:

Rising wool;
Body muscles look tense;
The gaze is directed in the direction of the source of experiences. Usually frozen and hardly blinking.

The most common situations are when a rat experiences negative emotions:

The appearance of new unfamiliar pets next to the rodent;
Unfamiliar environment;
Visit to the veterinary clinic.

Sometimes passions boil with such force that the animal begins to prepare for an attack. This happens when a new tenant moves into the cage. The aggressor must be immediately isolated, otherwise a fierce battle and spilled blood cannot be avoided.

Curiosity and interest can also cause teeth grinding.

Due to possible illnesses

Sometimes teeth grinding in a rat is a sign of pain or illness. However, more often than not, this behavior indicates happiness, relaxation, or may even be a natural behavior to ensure the correct length of the teeth. Rats tend to grind their teeth loudly when they are feeling unwell, in pain, or stressed. This type of sharp grinding usually comes from the back teeth. Also, these symptoms may indicate problems with the well-being of the rodent:

Reluctance to be communicated with.
Changes in behavior (apathy).
Decreased appetite.
Diarrhea, soft stools, or other forms of feces.
Low energy (lethargy).
Excessive drooling.
Tearful eyes.

Contact your veterinarian immediately if your rat exhibits these symptoms. Don't expect your rodent to get better on its own, as this could lead to more serious problems developing. Even though these symptoms may simply mean stress or anxiety, it's better to be on the safe side. If possible, remove your pet's teeth grinding and show it to your veterinarian.

Grinding teeth with pleasure

The most common situation for a characteristic creaking sound is a state of peace and joy. It occurs when the owner puts the animal on his shoulder, scratches behind the ear, strokes it and interacts with the pet in other ways. In this case, the decorative rat makes sounds whose meaning corresponds to the purring of a cat.

The animal shows its owner love and happiness from being taken care of. Sometimes body vibration is added to the sound. This is the highest degree of joy.

What happens if the incisors become too long?

A wild rat can usually keep its incisors to a reasonable length. However, her domestic companion often requires the help of a person who cares for her. Too long incisors can not only lead to injuries to the lower jaw, but also cause malocclusion (misalignment of the lower jaws). With an incorrect bite, other aggravations occur that can cause malaise or discomfort. Along with an incorrect bite, overgrown teeth cause root growth. When a root grows for too long, inflammation and infection are sure to occur.

There are many pet products that can help keep your rat's teeth looking their best. Chew blocks, treats, and toys all function as chewing devices, filing teeth down to a manageable size. Plus, these toys keep your rat active. Monitoring your rat's eating habits is a great way to make sure its teeth are healthy. A trip to the doctor can never hurt—even if your rat is a tiny creature, he will still feel pain acutely. Bad teeth and a sore mouth are no pleasure for any creature!

When should you be wary?

So, the same sound can mean both good and bad emotions; you need to delve into the context of what was “said.” Look at the environment, at the events that preceded the sound.

List of sounds that you should be wary of when you hear them:

The animal squeaks shrilly. If no external irritants are found that need to be eliminated, the animal should be taken straight to the veterinarian.
Grinding of teeth almost always means problems with chewing function. It is necessary to examine the animal's teeth. An infection can settle there. Only a veterinarian can see this.
The loud cry of a rodent means that the animal is scared and in danger. Stress factors for the pig must be eliminated, otherwise it can become seriously ill.
Wheezing when breathing is also a reason for urgent medical attention.

Each animal can bring personality and express special emotional notes. The squeak of a guinea pig is an expression of a palette of feelings. Recognizing them is a difficult but interesting task.

A rodent has bitten until it bleeds: what to do?

The situation when a domestic rat bites until it bleeds is alarming. This is not surprising, because history records so many diseases that were spread by rats. It was easy for rodents to bite a sleeping person and infect him with a deadly infection.

Decorative rats are not basement parasites. There is much less infection in their bodies. However, after a bite, you cannot stop the bleeding for some time so that all the bacteria that have entered it have time to get out. Next, the resulting wound is washed with a soap solution, for the preparation of which it is preferable to use laundry soap. Afterwards, the bite is treated with an antiseptic, and the edges are cauterized with iodine.

After being bitten by a rat until it bleeds, you will have to consult a doctor for vaccination against viruses that can infect your pet rodent.

Why does a rat pee on your hands?

The pet doesn’t pee so much as mark its owner, and that’s normal. Like dogs, rodents must “stake out” their territory, including their owner and his belongings. Marking differs from peeing by the volume of urine produced: a drop is enough to indicate ownership.

Rats often mark their hands

The rat “pees” on people if they are saturated with strong odors: perfume or detergents. It is almost impossible to stop a rat from marking. A young male can be castrated, but this will not be a 100% guarantee either.

Frequently asked questions about the care and maintenance of decorative rats

Features of incisors

Thanks to their strength, the animals chew through not only wood, bricks and concrete, but even metal. Incisors appear in rat pups a week after birth. Their growth process is accelerated - up to 2-3 mm per week. They reach their usual length by the age of two months. But their growth not only does not stop there, but also does not slow down.

The constant growth of incisors requires regular grinding. Excess length causes many problems, including the death of the animal.

They are covered with enamel only on the front. The back surface is covered with a soft, fast-wearing substance called dentin. This heterogeneous coating determines the sharpness of the incisors.

Nervous excitement and anxiety

Knocking, grinding and creaking are far from the only sounds that rats make with their teeth. Another sound option is the clicking of incisors. This sound made by a rodent indicates the following feelings and emotions of the pet:

Frightened;
extreme interest;
peak of curiosity.

It is worth noting that curiosity in rats is expressed only by this sound and no other.

You can distinguish fear from interest and overexcitation by a number of characteristic additional signs. Clicking symbolizes fear and negative emotions if the animal:

The body is tense;
the fur stands on end;
eyes do not blink;
the gaze froze on one point.

These manifestations are signs of fear and stress. If the animal not only clicks its teeth, but also squeals and hisses, it means it is ready to attack. If several individuals live in a cage, a violent fight can only be prevented by isolating the aggressive person.

Mineral composition

A rat tooth consists of three different layers:

enamels;
dentin;
pulp.

On top is hard enamel, which forms the crown. Enamel is mainly composed of calcium and other minerals. Beneath it there is a softer substance - dentin, which is larger than all other components combined. The dentin itself serves to protect the pulp from adverse influences. And in the soft pulp there are nerve canals and blood vessels. In addition, at the junction with the gum and jawbone, a peridontium is formed, which provides reliable attachment both to the alveolus and to adjacent incisors and molars. Mostly the molars of rodents (including mice, ground squirrels and others) have a similar structure, while the incisors have minor differences due to their functions.

The structure of molars

How then do animals use molars, and why do they not interfere with the work of the incisors when chewing? Thanks to their flat and wide shape, they are convenient not to chew, but to grind food. When a rodent eats food, it does not move its jaws up and down, but moves one back relative to the other. Therefore, the molars do not knock against each other, but rub.

Molars appear in baby animals in different ways:

the very first on the 19th day after birth;
second batch - on the 21st day;
the third and last molars appear 4-5 weeks after birth.

At the sixth week, the baby already has all the necessary incisors and molars. The growth of the latter continues until the fourth month, and then slows down and disappears. The enamel on them is very durable, its coefficient on the Mohs scale is 5.5 (a diamond with a hardness coefficient of 10 is taken as absolute). Therefore, its abrasion occurs very slowly and has practically no effect on the animal’s life.

The rat purrs (or croaks)

Happy New Year!! I wish you health, fulfillment of desires, good luck.

I treated with baytril and dexamethasone on the recommendation of a doctor - baytril for 10 days, dexamethasone for 3 days. After the first injection, I stopped purring. It all went away for a while, but now it’s the same thing again... I give loratodine and gamavit. Yes, and I noticed that I purr mostly in the evenings. Please tell me, in some human laboratory, eye swabs are mostly taken? Tell me at least which direction to go to find such a laboratory, except for the veterinary clinic.
