Witnessing cat tremors may ring alarm bells for us, cat parents. However, it helps to be aware of the causes of tremors in cats to help us keep calm and determine what to do when our cat exhibits such symptoms.

Tremors in cats are actually common, the causes of which range from benign to serious. It can be defined as involuntary, rhythmic, and periodic movements in the muscle that results in shaking in one or more areas of the body, where the muscle alternates between contracting and relaxing.

Tremors are observed when cats are awake and don't happen when they are sleeping. If, however, the shaking continues when your cat is sleeping, then it’s not considered a tremor.

When a cat is affected by tremors, involuntary movement may be observed in any part of their body. It can be localized in only one part of the body, or it may be generalized/ affect the whole body. Usually, localized tremors are observed in a cat’s head or rear limbs.

Causes of Tremors in Cats

There are many possible causes of cat tremors, and the symptoms may depend on which part of the body is affected. Among these causes are:

  • Congenital (at birth);
  • Genetic;
  • Injury or trauma;
  • Idiopathic (unknown);
  • Severe pain or weakness;
  • Cerebellar abnormalities;
  • Toxicity;
  • Inflammation;
  • Hypoglycemia;
  • A disease in the nervous system;
  • Kidney failure;
  • A side effect of certain medications;
  • Vestibular diseases;
  • Neuromuscular diseases;
  • Compressive spine lesions.

Wobbly Cat Syndrome

While cats are generally known to move gracefully, some cats are born with a rare condition that affects their balance. This condition is known as the wobbly cat syndrome, technically termed cerebellar hypoplasia in cats. Note that despite lacking in coordination, a cat that has wobbly cat syndrome can live a happy and full life just like other cats.

According to Dr. Joseph Mankin who is an associate professor of Neurology at the Texas A&M College of Veterinary Medicine & Biomedical Sciences, cerebellar hypoplasia in cats (a.k.a. wobbly cat syndrome) is when that part of the brain that is in control of coordination and balance called the cerebellum doesn’t properly develop.

As a result, the cat exhibits excessive head or leg movements. The main symptom of cerebellar hypoplasia in cats is a lack in coordination. For example, a cat’s hind legs may wobble when they stand or walk or their head may jerk when they eat or drink.

The condition doesn’t develop over time. Rather, it is inborn / observed from birth. According to Mankin, “the most common cause is an in-utero infection with the feline panleukopenia virus”.

There is no cure or treatment for cerebellar hypoplasia. However, it usually doesn’t have serious effects. Ideally, these cats are to be kept indoors and in homes that are free from hazards to avoid accidents or injuries.

Cat Trembling vs. Cat Tremor

The main difference between a cat tremor and other kinds of shaking such as cat trembling is that real tremors stop when a cat sleeps. On the other hand, other forms of shaking may continue when a cat is sleeping.

Treatment and How to Manage Cat Tremors


Because a tremor happens due to an underlying condition, what we want is to treat the underlying condition that is causing it. To find out the cause, lab tests may be needed for your veterinarian to be able to properly diagnose and determine the corresponding treatment if necessary. However, note that some tremors do not have any available treatment.

If the tremor is due to a drug, your veterinarian may recommend an alternate drug to prevent the tremor from happening. On the other hand, if toxicity is suspected, it is important to eradicate the toxin from your cat’s environment to avoid your cat being exposed further.

For example, your cat may have accessed a chemical substance around the home, or maybe they chewed on a plant that is considered toxic for cats. If that is the case, an antidote may be given to treat your cat.

Note from Dr. Vanderhoof: In such cases, it is helpful to refer to the ASPCA Poison Control website, which has a comprehensive list of toxic plants and household products. Pet parents can also call the number to speak to a veterinary toxicologist who will provide instructions that their vet can use to treat properly.

Certain tremors that are related to the nervous system may need surgery to treat the disease. Your veterinarian may also prescribe medications to help control the excessive movements.


One way to prevent the intensity of your cat’s symptoms is not to engage them in strenuous exercises. However, exercise is also beneficial to your cat so just make sure that the exercises are of low impact or are more relaxed. The prognosis mainly depends on treating the underlying disease successfully.

However, cats who have certain tremors that don’t have treatment may still live happily and without serious effects when they are given the proper care. When it comes to tremors, it is very important to be able to monitor your cat. With this, pet cameras such as the Petcube interactive pet camera would be very helpful to keep tabs on your cat and be able to know when something is amiss.
