Why does a cat shake all over just like that?

“Sleepy” tremor

Sometimes the owners notice that the cat trembles when it lies with its eyes closed. The tremor in this case is not permanent. Rather, we can talk about periodic shuddering of the body or its individual parts (for example, paws).

Don’t worry. If there are no other symptoms, such a tremor only indicates that the animal is as relaxed as possible and receives true pleasure from rest. True, sometimes a cat trembles from a nightmare, in which, for example, a huge dog is chasing it, or a coveted sausage is taken away. It’s not scary. The animal will wake up. and everything will work out. As a last resort, you can wake up.

Emotional arousal

Certain emotional states can cause your pet to tremble occasionally. For example, strong fear, discomfort from the appearance of strangers in the house, aggression. The tremor in this case is due to the tension that engulfs the cat. The animal looks like a stretched string that is about to burst, and from this it begins to tremble.

Not only negative emotions can cause this state. A cat experiencing bliss can also tremble periodically. Many owners notice that when they return from work in the evening and a bored cat rushes to them, rubs against their legs and purrs rather, it literally shakes with joy. This is normal. Do not leave your pet alone for a long time if it is so hard going through separation.

Sex hormones

A very common reason for a cat shaking is hormonal storms. They shock the animal’s body when it needs mating. During such periods, the male furiously marks everything around him, screams heart-rendingly, demanding the bride, and suffers from a tremor that covers his entire body. from ears to the tip of the tail.

does, shake, just

The same goes for cats. During estrus, they also often tremble. It is better not to allow such animal torment. If kittens are not in your plans, neuter the pet, or at least buy pills that reduce sex drive.

Situations of no concern

Tremor is not always the cause of the disease. There are a number of reasons when this phenomenon is not of particular concern.

Why does the cat tremble?

Pets (particularly cats), like humans, sometimes experience tremors (tremors). There are many reasons for its occurrence. Before helping your pet, you need to figure out why the cat is trembling.


The most common factor causing tremors in an animal’s body is cold. No one is immune from hypothermia. and the cat is no exception. If she is cold, she can tremble in different ways: large (this can be seen with the naked eye) or shallow (it is easy to notice the trembling by putting your palm to the pet’s body).

By itself, the tremor from the cold should not cause concern. However, it should be remembered that too low temperatures can make your cat sick. Therefore, you need to do everything possible so that she does not overcool and does not tremble from this (properly heat the room, use clothes for animals).

Shivering as an alarming symptom

There are many different pathologies in which a cat trembles. The most common:

  • Kidney dysfunctions often become a provoking factor of tremor in a cat. Require compulsory medical intervention, otherwise the animal may get chronic pathologies (for example, urolithiasis).
  • Rhinotracheitis is a disease of the musculoskeletal system. With it, the limbs usually twitch. Can be fatal if left untreated.
  • Epilepsy is a fairly serious medical condition that requires the help of a veterinarian. The body of the cat shakes finely with him. In addition, there are symptoms such as “glass” eyes, increased salivation, as well as decreased appetite, apathy. Your cat can become paralyzed if left untreated.
  • Parasite infestation is one of the most common causes of trembling in cats. Diseases of this group include, for example, toxoplasmosis, flea infestation. If the animal periodically twitches its head, it is most likely that an ear mite pesters it.
  • Otitis media or plugs in the ears also provoke head twitching.
  • Exhaustion of the body. If the cat is shaking with a small shiver, it is inactive, indifferent to games and other entertainments, perhaps it lacks nutrients, vitamins or beneficial microelements. Especially detrimental to the health of the pet is the deficiency of B vitamins and calcium. Diet revision can solve the problem. With a normal diet, the cat will stop shivering.

In search of an answer to the question of why a cat is trembling like an aspen leaf, you should analyze all the factors and take a closer look at the pet. Are there any other symptoms and, if so, which ones; whether the emotional state of the animal is stable; does it want to “walk”; trembling occurs when the pet is asleep or awake; etc.

All of this is of great importance. If time passes, and the situation does not return to normal or there are accompanying warning signs, the cat should be shown to a specialist as soon as possible.

If the pet is cold

Sometimes a shiver in a cat occurs as a reaction of the body to hypothermia. When an animal is cold, it shakes in different ways, for example, shallowly. In this case, it is impossible to visually notice the tremor, but if you put your hand to the body, you can feel how it vibrates. If the cat’s chill is visible to the naked eye, then the cat is trembling large. Often this condition is observed after washing the fur, when the body and head of the animal are wet, it actively shakes them up, but cannot warm up, because the room is not warm enough. Hypothermia often occurs when a cat walks outside for a long time in winter with severe frosts. Once in the house, the pet frowns, its muscles flinch, its legs and tail shake.

Stormy emotions

During overexcitation, you can also notice that the cat is shaking all over the body. This reaction can occur to both negative and positive emotions. If the animal senses danger, adrenaline, the hormone of fear, enters its bloodstream. When walking, the cat shakes off its tail, its back is arched, if the nerves are at the limit, you can see how the eye twitches.

Many owners note that a pet’s tremor occurs during games, caresses, a long-awaited meeting with the owner. If the kitten shivers after eating, this is also the norm. Experts explain this phenomenon by the fact that, when eating your favorite food, many muscle groups contract in the animal from positive emotions, which is why tremors appear.

Main reasons

Why the cat is trembling. 6 possible reasons

Often the shiver in a cat appears when the animal is very cold, for example, after bathing, if the temperature in the room is not comfortable enough and the pet is cool. But sometimes the cat can shake violently due to the progression of a dangerous disease in the body, such as epilepsy, rhinotracheitis, renal dysfunction. If the pet is lethargic, it suddenly became ill, and trembling all over the body is clearly noticeable, you should not hesitate to visit the veterinarian.


Tremors can be a symptom of a dangerous disease in which the animal is worried about tremors, chills. If a kitten or an adult cat constantly has a tremor of the whole body, it is possible that the following diseases occur in the body:

  • Rhinotracheitis. An infectious pathology that affects the eyes and respiratory organs, and if treatment is untimely, the musculoskeletal system is involved in the pathological process. The animal’s temperature rises, due to strong intoxication, the kitten vomits, and also worries about tremor, fever.
  • Helminthiasis. Often they cause the cat’s hind legs to shake.
  • Renal dysfunction. A dangerous pathology that negatively affects the functioning of internal organs and systems. If the pet trembles even when lying down, while there are problems with urination, it is better not to hesitate to visit the doctor.
  • Epilepsy. A serious and dangerous disease that can begin to bother the animal as early as 2-3 months. During an attack, the pet is unconscious. Due to involuntary muscle contractions, the cat shakes its tail, its head, its paw can coward, its eyes become glassy, ​​the animal is completely disoriented.
  • Exhaustion of the body. Often this condition is observed with malnutrition, after suffering a serious illness, after surgery. The lack of vitamins causes the cat to tremble, therefore, if such a symptom bothers, the owner should review the diet, give the pet additional vitamin supplements.

Hormonal Bursts

Heat is a common factor that causes a cat or cat to tremble. The feline sex drive is so strong that the animal during this period becomes unlike itself. It constantly yells, does not eat, walks on the heels of the owner, shakes its paws, tail, shifts its hind legs. From overexcitation, there is a tremor of the head, back, chills can disturb even in sleep. If the owner does not plan to breed offspring, it is better to save the four-legged friend from such suffering by neutering or neutering him.

Fear or intense fear

A common reason for shaking a cat with small shivers. The animal shudders nervously, shakes its tail, breathes faster due to the release of adrenaline, the hormone of fear, into the bloodstream. Due to stress, tremors develop, which disappear as soon as the animal calms down.

Intense tremors


Fear is the second reason a cat shivers. Many people believe that nothing can frighten a cat, however, this animal is very vulnerable and fragile, it is easy to scare and offend it. A cat can get stressed after a change of food, or when strangers are in the house. In general, there are many factors that can cause a cat to get scared, stressed, and shiver.

Croup tremors and generalized tremors

Spinal lesions (compression fractures, tumors, deformation of the intervertebral discs, stenosis of the spinal canal) can lead to weakness of the lower extremities and their trembling when the animal tries to stand up. With the further development of the disease, paralysis occurs.

Weakness as a result of an illness or pain can lead to trembling of the animal’s limbs or general trembling. For example, a sharp object swallowed, damaging the stomach or intestines, can cause the animal to meow plaintively, arch its back and tremble.

Neuromuscular diseases, degenerative neurological pathologies, myelin deficiency, metabolic pathologies, and even poisoning with toxins (for example, organophosphorus) can cause massive tremors throughout the animal’s body.

Trembling limbs

Tremors in the limbs of a pet can be caused by herpesvirus infection or rhinotracheitis of the animal. The main symptoms of this ailment are purulent discharge from the nose and eyes, cough, vomiting, fever.

Tremors of the limbs can be triggered by worms or cystitis, shaking the limbs, the cat tries to relieve itching or pain during the activity of helminths or the resulting discomfort during urination.


Tremors are frequent convulsive contractions of an animal’s muscles, shaking or shuddering of the body or parts of it. The reasons for this phenomenon can be physiological and pathological. There is also an idiopathic tremor, that is, the trembling of an animal, the cause of which cannot be found out. The tremors can be small and subtle, especially in furry breeds, but can be easily felt by placing your hand on the animal. Tremors can be large, visible to the naked eye.

Physiological tremors

Involuntary rhythmic muscle contractions that are associated with the mechanisms of regulation of the state of the animal are referred to as physiological tremors.

Cold shiver is a thermoregulatory mechanism of physical protection of the animal’s body from hypothermia. As soon as the temperature becomes uncomfortable and even dangerously low for the animal, its body begins to tremble finely. This allows you to quickly provide heat production and save the life of the animal. If the pet freezes, then you need to either dress it, or increase the temperature in the room where it is kept. Because this mechanism is effective to a certain extent. The cat may become hypothermic and ill.

Emotional experiences of a high degree (fear, joy). Under the influence of frightening events for a cat, her body, like the human body, secretes certain hormones, under the influence of which tremors and chills begin.

Joy when a living creature is overwhelmed with emotions, for example, the return of the owner from work can cause a small tremor in the animal. The animal trembles when it lies on the lap of its beloved owner and purrs.

Some experts claim that the animal may have a slight shaking, which is caused by reflex when the animal’s stomach is full.

The shiver of arousal is the shiver of a hunter or a sexually aroused animal.

The cat trembles, as if she is cold: the reasons for the tremor

When a shiver suddenly runs through a cat’s body, it alarms and even sometimes frightens the owners. This phenomenon is called tremor, it is caused by the involuntary contraction of one or all muscle groups. There are physiological and pathological causes of its occurrence, which can only be accurately determined by a veterinarian. But in order to help the pet in time, the owner must know the reasons why the cat is trembling.

Pathological causes of tremor

The reason why the cat is shaking, as if it is cold, although it is at home in a comfortable environment, may be pathological factors. In this case, the tremor is often accompanied by the following clinical symptoms:

  • photophobia;
  • inactivity and lethargy;
  • aggression;
  • pain syndrome;
  • an increase in body temperature indicators;
  • diarrhea or constipation;
  • vomiting;
  • purulent discharge from the nasal cavity or eyes;
  • impaired coordination of movements.

Often the presence of pathology in a cat is evidenced by tremors of certain parts of the body or muscle groups when only the head, front or hind limbs are shaking.

Important! Tremor must be distinguished from seizures, which are always accompanied by pain. In kittens up to 5-6 months of age, when they have an intensive development of the central nervous system, seizures can be of a physiological nature. In other cases, seizures indicate the presence of serious dysfunctions of the brain due to infectious or traumatic factors.

There are many pathological reasons why kittens and adults tremble.

Deficiency of calcium and B vitamins in the body provokes degenerative processes in muscle tissue in cats.

An infectious rhinotracheitis may be the reason that the kitten is shivering. In addition to tremor, this disease is accompanied by cough, purulent discharge from the eyes and nose, a significant increase in body temperature and digestive disorders.

With the development of helminthic invasions, when helminths clog the intestines of the pet and release a huge amount of toxic products of their vital activity, the kitten experiences intoxication phenomena, it becomes lethargic and trembles all over.

The response of the body to the introduction of general anesthesia. If the cat shakes after surgery for more than 6 hours, then this may indicate the development of internal bleeding. In this case, urgent medical attention is required.

Body trembling in cats provokes acute inflammatory processes in the organs of the genitourinary system and attacks of urolithiasis.

Otitis media caused by ear mites or other factors leads to frequent twitching of the head. The cat scratches the sore ear, hits it, tilts its head towards the affected organ. As a result, scratches and bruises appear in the area of ​​the auricles. Lack of treatment leads to the transition of inflammation to the inner ear and meninges, which provokes death.

During acute liver failure, the cat appears vomiting and diarrhea, at the initial stage it trembles slightly, and at the stage of failure of the affected organ it trembles all over.

Head tremor may indicate traumatic brain injury, encephalitis, cerebellar lesions, drug overdose.

If the kitten does not walk well and at the same time his whole body is shaking, then this may indicate injuries to the spinal column caused by congenital abnormalities, compression or bruises. In adult cats, these symptoms are the result not only of trauma, but also of the development of tumors or deformities of the intervertebral discs.

If a kitten suddenly becomes lethargic, begins to tremble at first slightly, and then with an increasing amplitude, then such a tremor and lethargy most often indicate poisoning. If the baby is not delivered to the clinic, then he develops convulsions and becomes fatal.

The cause of the tremor may be borreliosis, which occurs after a tick bite. The insidiousness of the disease lies in the long latency period, when clinical signs may appear several months after infection.

Tremors combined with lethargy may be one of the signs of toxoplasmosis in cats.

If the kitten does not walk well, shakes, turns in place, or is poorly oriented in space, this may indicate the presence of such a serious congenital pathology as hydrocephalus.

Tremors of the limbs, turning into convulsions, can occur in a cat during childbirth or within a week after. This is called eclampsia. It indicates an acute lack of calcium in the animal’s body. If left untreated, the cat will develop seizures that can be fatal.

What is tremor in cats

Tremor in cats is a convulsive contraction of the muscles of the animal’s body, which is visually expressed in the form of small tremors. Sometimes the whole body of a cat is shaking, but some parts of it can also shake. An involuntary muscle contraction, called tremor, can also occur at rest, indicating maximum relaxation of all muscle groups. However, trembling often indicates that the cat has serious health problems and the animal requires urgent treatment.

Important! If long-haired cats are shaking with small tremors, then you can feel this only if you put your hand to the animal. But sometimes the tremor is clearly visible and accompanied by other alarming symptoms.

How to treat tremors and seizures in cats

When trying to figure out how to cure a tremor in a cat, the owner of the animal often acts by analogy with human disease. This is not the right way to go. organisms of a cat and a person are arranged in different ways. Sometimes the owner, not realizing this, proceeds to self-treatment. At the same time, he loses time: the effect of therapy is not achieved, the signs of the disease are sometimes erased, but the disease itself progresses.

You need to understand that tremors in a cat are treatable only after finding out the cause. An accurate diagnosis cannot be made without examination, laboratory and instrumental studies.

Further prognosis depends on the type of pathology. Sometimes a course of vitamins is enough to completely restore the conduction of nerve impulses. However, the disease often does not respond to therapy. Each specific case requires separate consideration.

Knock down the temperature correctly

You should not try to bring down fever of 40 degrees or higher at home with antipyretic drugs intended for people. Only in the most extreme cases, if the veterinarian does not arrive soon, and the high temperature in cats has risen above 40 degrees, the pet is given Analgin. However, physical methods such as putting ice on your inner thighs or your neck are the best ways to bring down the heat. Alternatively, you can wrap your pet in wet gauze.

The most correct decision when the temperature rises for the cat will be one thing. to urgently take the pet to the veterinary clinic.

Why is it better not to call a veterinarian to the house, but immediately go with a pet with a fever to the clinic? The fact is that the high body temperature of the animal could be caused by a variety of viruses. It will be possible to determine them only upon passing the necessary tests. So, you can buy precious time to save your pet’s life.

Sterilization is an ordinary operation and complications after it are extremely rare. After the operation, it is important to monitor the condition of the cat in order not to miss the alarming symptoms and to prevent severe inflammation. Remember, the sooner you discover something was wrong, the easier it will be to cure your pet and avoid negative consequences. Treat your kitty with care and it will help her get better sooner.

Noticing that the cat twitches in a dream, the owner may be concerned about the pet’s well-being. When it comes to an adult cat, suspicions are far from unfounded. Let’s figure out why cats tremble in their sleep and what it can indicate if the cat twitches too much.

It was cats, or rather, their dreams, that made it possible to prove to the whole world that animals also plunge into the world of dreams. over, scientists suggest that our pets’ dreams are much richer and more dynamic than ours.

It all started with the fact that doctors began to study the phases of a person’s sleep. An experiment was carried out on a group of cats to support our hypothesis that healthy people lose their ability to move during REM sleep.

All animals removed a small part of the brain that was responsible for muscle atony during REM sleep. After the complete rehabilitation of the animals, the scientists’ suspicions were damaged. The observed cats got up on their paws, walked confidently, turned their heads, as if watching someone. While in a state of sleep, cats sniffed and turned their ears. Experiment Proves Cats See, Hear, and Touch Dreams.

A healthy, adult animal does not move during REM sleep, although rapid eye movements and slight twitching are considered normal.

With the development of medical equipment, it was possible to prove that during a dream, cats experience real emotions: fear, joy, excitement, aggression. Next to the animals under observation, the “pheromones” of a same-sex cat were sprayed and the subject showed aggression. In the opposite case, when spraying the smell of an animal of the opposite sex, the observed behaved calmly or interested. That is, animals that were not paralyzed by the REM phase not only sensed the external world, but also made natural, instinctive decisions. These observations made it possible to conclude that in their dreams cats seeing themselves and their surroundings is very realistic.

The experiments were carried out on cats, dogs and rodents. Cats surprised scientists by very naturally emitting hunting in their sleep. The dogs unexpectedly hinted at a bestial essence, emitting the behavior of wild wolves. Rodents broke all records, because even in a dream they were able to solve the tasks assigned to them.

The study of human and animal sleep continues. Of course, today it is no longer practiced to remove part of the brain for the sake of observation. To relieve atony during the REM phase, blockages of a part of the brain are used. Today’s scientists are on the cusp of a big discovery as experiments have included observations of brain activity using highly sensitive scanners. There is no doubt that cats are dreaming, but perhaps soon we will find out exactly what their dream world looks like. Already today, scientists have managed to find out that kittens see their first dreams while still in the womb.

The cat is trembling. a complete list of reasons from the vet

Hypoxia. Oxygen starvation in felines can occur with blood loss and blood diseases. Sometimes the process takes place after a fight between relatives. However, the cat community is organized wisely. the weak simply retreats, preventing such serious injuries.

Toxoplasmosis. It is an infectious disease in humans and animals resulting from Toxoplasma infection. In addition to the fact that the cat is lethargic and sometimes trembles, with toxoplasmosis, no more symptoms may appear. The disease often has a latent course. But in some cases, it will also appear:

What it means if you cat’s tail shakes like this

  • drowsiness;
  • alternation of diarrhea and constipation;
  • refusal to feed;
  • coughing, sneezing, nasal discharge;
  • if the cat is pregnant, there may be abortions and stillbirths.

The signs may disappear, but the fact that the cat is constantly trembling should alert and force you to see a doctor in order to conduct serological tests to detect antibodies.

Toxocariasis and toxascariasis. Often, helminths cause nervous phenomena. The cat shakes not from the very presence of roundworms in the intestines (although with a large accumulation and blockage this is possible), but from the toxins that Toxocara secretes into the host’s body. The waste products of the parasite, acting on nerve cells and ganglia, disrupt conduction and cause seizures.

If the intestines are clogged with roundworms, then the kitten sometimes trembles after eating. During this period, a full stomach presses on the intestines. and the roundworms activate their movement, which causes twitching.

If the animal is not given preventive deworming every quarter, then the worms can also cause epileptic seizures. In this case, they will be joined by:

  • loss of appetite;
  • diarrhea alternating with constipation;
  • bloating;
  • urge to vomit.

But these signs can also occur with rabies, so you need to be careful.

Epilepsy. Epileptic seizures in cats are also associated with seizures. The causes of this disease are different, for example, injury. But in any case, an epileptic seizure is only a symptom of the underlying pathology. malfunctioning of the brain.

Hydrocephalus. Dropsy of the brain is a congenital and quite rare disease for cats (it mainly manifests itself in Siamese cats). If a small kitten develops a convulsion, the cause may be swelling or dropsy. Most often, a sick animal dies quickly. To make an accurate diagnosis, an examination is necessary.

Brain tumors. Cancer in cats can cause seizures. Not only brain tumors are involved, but also other organs. If a tremor is detected in a kitten and during the examination no other reasons are found, then, most likely, an accurate diagnosis will be made by an MRI.

Head trauma. Any trauma can cause tremors in the cat, much less damage to the head. In this case, the cat shakes immediately after being injured. It goes away over time. If the injury is minor, then the condition is completely normalized. If the brain damage is severe enough, tremors and convulsions can accompany the animal until death.
