Watching your cat suddenly tremble or shake can be a frightening experience. Tremors in cats are involuntary muscle movements that can affect different parts of the body, such as the head, legs, or the entire body. While some tremors are harmless and temporary, others may signal an underlying medical issue that requires attention.
This blog will help you understand the possible causes of tremors in cats, the common symptoms to watch for, and when it’s time to visit the veterinarian.
What Are Tremors in Cats?
Tremors are rhythmic, involuntary muscle movements that resemble shaking, twitching, or jerking. They can be localized (affecting a specific area like a leg or head) or generalized (impacting the whole body). Tremors are different from seizures—although both involve abnormal movements, seizures often include loss of consciousness and more intense convulsions.
Common Causes of Tremors in Cats
-
Cold or Stress
- Just like humans, cats can tremble when they’re cold or anxious. A shivering cat might need warmth or a quiet place to relax.
-
Pain or Injury
- Muscle tremors may be a response to pain. An injured limb, inflamed muscles, or internal discomfort could trigger shaking.
-
Neurological Disorders
- Conditions like cerebellar hypoplasia or brain tumors can interfere with normal nerve function, causing tremors.
-
Toxin Exposure
- Ingesting toxic substances such as chocolate, certain houseplants, human medications, or pesticides can lead to tremors. This is a veterinary emergency.
-
Low Blood Sugar (Hypoglycemia)
- Low blood sugar is especially common in kittens or diabetic cats, and it can result in trembling, lethargy, and disorientation.
-
Liver or Kidney Disease
- As toxins build up in the body due to organ dysfunction, neurological symptoms like tremors may appear.
-
Feline Infectious Diseases
- Infections like feline infectious peritonitis (FIP) or toxoplasmosis may affect the nervous system, causing muscle twitching or tremors.
-
Old Age or Degenerative Conditions
- Senior cats may develop age-related tremors due to muscle weakness or declining nervous system function.
Symptoms That Often Accompany Tremors
Tremors don’t always appear alone. Keep an eye out for these additional symptoms:
- Vomiting or diarrhea
- Loss of appetite
- Lethargy or weakness
- Unsteady gait or difficulty walking
- Drooling or foaming at the mouth
- Seizures or collapse
- Disorientation or confusion
If your cat is experiencing any of these symptoms alongside tremors, seek veterinary care immediately.
Diagnosing the Cause of Tremors
Your veterinarian will conduct a comprehensive physical exam and gather detailed information about your cat’s medical history and recent behavior. To pinpoint the underlying issue, the vet may recommend:
- Blood tests: To check for infections, low glucose levels or organ function.
- Urinalysis: To detect kidney disease or toxins.
- X-rays or ultrasounds: To identify injuries or organ issues.
- MRI or CT scan: If a brain or spinal cord issue is suspected.
- Toxin screening: If poisoning is a concern.
Treatment Options for Tremors in Cats
Treatment depends on the root cause. Some examples include:
- Warming and calming: For tremors caused by cold or anxiety.
- Pain relief or anti-inflammatory medications: If injury or inflammation is the cause.
- Antidotes or detoxification: For toxin ingestion.
- Antibiotics or antivirals: If infections are involved.
- Dietary changes and supplements: For metabolic or nutritional causes.
- Ongoing management: For chronic neurological conditions.
Your veterinarian might suggest adjustments to your cat’s daily routine, including creating a more secure living space or introducing a healthier, well-balanced diet.
When to See a Vet
While some tremors are mild and temporary, you should call your veterinarian if:
- The tremors last more than a few minutes
- Your cat shows signs of pain, confusion, or illness
- Other symptoms may include fatigue, episodes of vomiting, or even seizures.
- You suspect poisoning or toxin exposure
Never attempt to self-medicate or diagnose at home—doing so may worsen the condition.
How to Prevent Tremors in Cats
While not all causes of tremors are preventable, you can reduce the risk by:
- Keeping toxic substances out of reach
- Feeding a balanced, nutritious diet
- Providing regular vet checkups and vaccinations
- Managing chronic illnesses like diabetes or kidney disease
- Offering a safe, low-stress home environment
Final Thoughts
Seeing your cat experience tremors can be concerning, but identifying potential causes and recognizing the right time to get veterinary help can greatly improve outcomes. If your cat experiences unusual shaking or tremors, don’t wait—reach out to your vet for professional advice and prompt care.
Your pet's health is worth the attention.
