Vet Insights: Why Is Your Cat Shaking? Understanding Tremors in Cats
Seeing your cat shake can be alarming, but not all shaking signals a serious problem. However, it often points to an underlying issue that deserves attention and may require veterinary or pet homeopathic evaluation.
This article covers the possible reasons why your cat might be shaking and how to distinguish between harmless behavior and signs of a problem. Learn what actions to take to protect your cat’s health.
What are Cat Tremors?

Tremors in cats are involuntary, rhythmic movements such as shivering, twitching, or trembling that the cat cannot control. These body or limb movements can vary in intensity and often signal an underlying issue.
Shaking in cats can affect the entire body or be limited to specific areas such as the head, legs, or tail. The intensity and location of the tremors often provide clues about the underlying cause.
In many cases, tremors signal an underlying issue involving the brain, nerves, spinal cord, or muscles that control movement. Understanding the root cause is key to ensuring accurate diagnosis and effective treatment.
Cat Shaking vs. Tremors: What’s Normal and What’s Not
Cats may twitch or shake during the REM stage of sleep, which is when dreaming occurs. These small, involuntary movements are completely normal and usually seen in relaxed, sleeping cats. In this context, shaking is not a cause for concern.
Temporary trembling in cats can occur during high-arousal moments like stalking prey, reacting to catnip, or during a confrontation. These episodes are usually brief and stop once the cat is distracted or the stimulus is removed.
When should you be concerned about tremors in cats?
Ongoing shaking or tremors, especially when paired with other symptoms, often indicate a deeper health concern. It's important to consult your veterinarian promptly to identify the cause and ensure your cat gets proper care.
Muscle tremors that develop in adult cats are unusual and may signal a serious health problem. Early veterinary assessment is crucial to identify the cause and begin effective treatment.
Similar Symptoms to Differentiate
Shivering in cats is usually a response to cold and typically stops once the cat warms up. Unlike tremors, shivering is temporary and generally not associated with other symptoms or underlying health issues.
Feline Hyperesthesia Syndrome (FHS) causes sudden, intense twitching along a cat’s back or hindquarters, especially the base of the tail, which can resemble tremors. It’s typically brief and is marked by extreme sensitivity to touch in the affected areas.
Tremors may resemble seizures, but seizures are distinct episodes caused by abnormal brain activity, leading to uncontrollable muscle movements. Some conditions, such as pyrethroid toxicity, can cause both and require immediate veterinary care.
What are the Common Causes of Feline Tremors?
Tremors in cats can result from medical conditions, environmental influences, or behavioral factors. In this section, we’ll explore the most common causes to help you better understand what might be affecting your cat.
Metabolic and systemic issues
- Hypoglycemia, or low blood sugar, is a common cause of tremors in cats, especially if they haven’t eaten for an extended period. It’s particularly concerning in diabetic cats receiving too much insulin and in young kittens with inadequate nutrition.
- Kidney disease in cats can lead to toxin buildup in the blood, causing symptoms like shaking, appetite loss, neurologic signs, and overall weakness. It’s especially common in older cats but may also result from infections, toxins, or tumors. Cancer, diabetes, and high blood pressure may also be factors.
- When the liver isn’t functioning properly, toxins can build up in a cat’s system, leading to tremors and other symptoms. Prompt veterinary care is essential to manage liver disease and prevent serious complications.
- Electrolyte imbalances in cats can cause tremors and often result from issues like a blocked urethra or severe fluid loss due to vomiting or diarrhea. These imbalances can quickly become life-threatening and require immediate veterinary care.
- Insulinoma is a rare tumor in cats that triggers excess insulin production, causing severe drops in blood sugar. This can lead to tremors, weakness, and other serious symptoms that require immediate veterinary attention.
- Hypocalcemia, also known as low blood calcium, can lead to tremors, particularly in mother cats producing large amounts of milk after giving birth. This condition can become serious quickly and requires immediate veterinary attention.
Environmental and external factors
- Hypothermia, or low body temperature, can cause cats to shiver as a natural response to generate warmth. Kittens are especially at risk due to underdeveloped temperature regulation, making hypothermia potentially life-threatening in newborns.
- Conversely, hyperthermia, or an elevated body temperature above 102.5°F, can cause tremors in cats and is often a sign of infection, inflammation, or illness. Prompt veterinary attention is important to identify the underlying cause and prevent complications.
- Trembling or twitching in cats can be a sign of poisoning from exposure to toxins such as lead, rodenticides, spoiled food, or certain medications. Permethrin, commonly found in dog flea products, is especially dangerous and potentially fatal to cats.
- Many common household items and plants, such as lilies, chocolate, coffee, and poinsettias, are toxic to cats and can cause rapid, severe symptoms. Immediate veterinary care is essential, and consulting a qualified pet homeopath may provide additional support.
- Certain veterinary medications can cause tremors in cats as a side effect. If your cat begins trembling after starting a new medication, contact your veterinarian promptly to evaluate the reaction and adjust treatment if needed.
- Tremors may occur as a temporary side effect while a cat recovers from anesthesia or sedation. These movements are usually short-lived, but monitoring your cat closely and consulting your vet or pet homeopathy expert if symptoms persist is important.
Neurological conditions
- Feline cerebellar hypoplasia is a congenital condition where the cerebellum doesn’t fully develop, affecting coordination and balance. Cats with this condition often show “intention tremors,” or shaking that occurs during focused activities like eating or playing.
- Brain tumors in cats may lead to neurological symptoms ranging from subtle tremors to severe seizures. These signs often progress over time, making early veterinary evaluation essential for proper diagnosis and treatment planning.
- Feline Hyperesthesia Syndrome (FHS) is a multifaceted disorder characterized by extreme sensitivity in the lower back area, leading to symptoms like twitching, rippling skin, and abrupt changes in behavior. Its underlying causes may be neurological, psychological, or skin-related.
- Infections such as toxoplasmosis, tetanus, or Feline Infectious Peritonitis (FIP) can lead to tremors and other neurological symptoms in cats. Even mild illnesses like cat flu may cause head shaking as the cat tries to clear mucus.
- Polyneuropathy is a chronic nerve disorder in cats that can cause generalized or localized limb tremors. It affects multiple peripheral nerves and may lead to weakness, uncoordinated movement, and progressive muscle loss.
- Degenerative encephalopathy in cats includes conditions like cerebellar cortical degeneration and lysosomal storage diseases, which can cause intentional tremors, especially in the head. These disorders progressively affect brain function and often lead to worsening motor control.
- Vestibular disease disrupts the inner ear and brain functions that control balance, causing symptoms such as head tremors, stumbling, and poor coordination. It often develops suddenly and typically requires immediate veterinary attention.
Pain, fear, and shock
- Cats may tremble or shake in response to severe pain, even though they typically hide discomfort. Underlying causes can include ear infections, tumors, or internal injuries, making prompt veterinary evaluation essential when tremors are observed.
- Strong emotional responses such as fear, phobia, or anxiety can cause trembling in cats. After such episodes, a cat may display defensive behaviors like aggression or heightened protectiveness.
- Trembling can be a sign of shock in cats, typically caused by severe injury, trauma, or significant blood loss. Additional symptoms may include a rapid heart rate, cold limbs, and pale gums, requiring immediate emergency care.
When to Seek Veterinary Attention for Tremors in Cats
If your cat experiences tremors accompanied by other concerning symptoms, seek veterinary care immediately. These signs may point to a serious underlying condition or medical emergency that requires prompt attention:
- Sudden, persistent, or severe shaking: Tremors that start abruptly, last more than a few minutes, or become intense may signal a serious neurological or systemic issue.
- Shaking with other concerning symptoms: Symptoms like vomiting, difficulty walking, loss of balance, reduced appetite, or signs of self-injury may indicate a deeper medical problem requiring urgent care.
- Suspected poisoning: Exposure to toxic substances, such as household chemicals, plants, or human medications, can quickly cause life-threatening symptoms, including tremors.
- Signs of shock: Cold limbs, a rapid heart rate, pale gums, or lethargy alongside shaking could indicate shock, which needs emergency treatment.
- Severe Feline Hyperesthesia episodes: If an FHS episode lasts longer than 2–3 minutes or happens frequently, it may signal worsening neurological dysfunction that should be evaluated.
If your cat displays mild to moderate symptoms of FHS or has repeated bouts of low blood sugar, prompt veterinary attention within 24 hours is recommended. Early care helps manage the condition and avoid more serious health issues.
Keep your cat warm if they’re hypothermic, or help them cool down gradually if they’re overheated. If low blood sugar is suspected, a small amount of honey or maple syrup rubbed on their gums may help, but always consult your veterinarian or a qualified pet homeopathy expert first.
If your cat experiences a shaking episode, try to record a video on your phone. This can provide valuable information for your veterinarian to help diagnose the cause more accurately.
Diagnosing Cat Tremors: What Your Veterinarian Will Look For
A thorough veterinary exam is essential to determine the underlying cause of your cat’s tremors. Accurate diagnosis ensures your cat receives the proper treatment and care as quickly as possible.
Taking of medical history
Your vet will also ask about your cat’s diet, living environment, and any possible exposure to toxins such as flea treatments, household chemicals, plants, or medications. Recent changes in your household may also be important in identifying triggers.
During the physical exam, your vet will observe your cat’s movements, check heart rate, listen to the lungs, and assess body temperature (normal range: 100.5–102.5°F). A thorough neurological evaluation will also be performed to test reflexes, coordination, and nerve or muscle function.
Routine laboratory tests
Routine lab tests play a key role in diagnosing the cause of your cat’s tremors. Blood work, often including a complete blood count, biochemistry panel, and thyroid levels, along with urinalysis, helps evaluate overall health and detect underlying issues.
To rule out viral causes of tremors, your veterinarian may test for infections like FeLV and FIV, which can impact the nervous system. In complex cases, a cerebrospinal fluid (CSF) analysis may be performed to detect neurological inflammation or infection.
Diagnostic imaging procedures
Diagnostic imaging, such as X-rays and ultrasound, can help evaluate your cat’s overall health and detect internal issues. If structural abnormalities, particularly in the brain, are suspected, advanced imaging like CT or MRI scans may be recommended for a more detailed assessment.
Based on initial exam results, your veterinarian may recommend specialized evaluations such as a dermatological assessment, pain screening, neurological testing, or behavioral analysis. In some cases, a medication trial may be used to evaluate your cat’s response to targeted treatments.
Conventional Treatment Options for Tremors in Cats
Treating cat tremors begins with identifying the underlying cause through veterinary diagnosis. Once the root issue is found, the focus shifts to targeted treatment to relieve symptoms and support your cat’s recovery and overall health.
Common examples of treatment
- Treatment for toxicity may involve immediate hospitalization, IV fluids, and decontamination procedures such as administering activated charcoal. Identifying and removing the toxic substance from your cat’s environment is also essential to prevent re-exposure.
- Hypoglycemia is treated by quickly raising blood sugar levels, usually with oral glucose or a veterinarian-administered injection. Fast intervention is critical to prevent worsening symptoms and ensure your cat’s safety.
- Kidney failure in cats is typically managed with fluid therapy, prescription diets, and medications to support kidney function and reduce symptoms. Early and consistent treatment can help slow disease progression and improve quality of life.
- If a medication is causing your cat’s tremors, your veterinarian may recommend adjusting the dosage or switching to an alternative. Promptly addressing side effects helps ensure your cat’s safety and treatment effectiveness.
- Neurological conditions like seizures or FHS may be treated with medications such as gabapentin, methocarbamol, or phenobarbital to control muscle activity, and fluoxetine or amitriptyline for anxiety-related symptoms. In complex cases, surgery or consultation with a veterinary behaviorist may also be recommended.
- Managing anxiety or stress in cats involves identifying and removing triggers, providing a calm and secure environment, and using tools like pheromone diffusers. Behavior modification techniques may also help reduce stress-related tremors and improve overall well-being.
- Supportive care focuses on keeping your cat safe and comfortable, especially if tremors affect mobility or coordination. This may include blocking access to stairs, using stable bowls, providing an easy-access litter box, and adding padding near elevated surfaces to prevent injury from falls.
- The prognosis for cat tremors depends on the underlying cause. Some conditions are fully treatable, while others may require long-term management. In certain cases, there may be no specific cure, but supportive care can still improve quality of life.
