A myelogram (study of the spine using dye) may be recommended to assess for the presence of tumors or disc disease. In these patients, collection of cerebrospinal fluid (CSF) may be beneficial to better determine the exact cause of the shaking. These evaluations may reveal abnormalities in the brain or spinal cord. These may include X-rays, magnetic resonance imaging (MRI), and computed tomography (CT-Scan), especially in cases where the extremities are involved. Other diagnostic tests may then be performed. If the cause of the shaking involves the central nervous system, then the initial laboratory tests may be found to be within normal limits. As part of the complete exam, a lab evaluation of your cat would include a complete blood count, biochemistry profile including an electrolyte panel, and an urinalysis. He or she will also perform a complete physical exam on your cat. To try to determine the cause, your veterinarian will likely want to review your cat’s complete medical history as well as get a thorough background of the symptoms, the time of onset, and possible incidents that might have led to this condition.


Though it is helpful for you to have a better understanding of why your cat is shaking, I always recommended that you contact your veterinarian immediately to begin the process of determining the cause(s). It may not be obvious that the shaking is a symptom of a medical condition, which may have significant adverse consequences, so shaking should not be ignored. If the shaking or tremors are involuntary, what you will observe are repetitive muscle movements that alternate between contraction and relaxation, usually involving either rapid or slow movements (twitching) of one or more body parts.Īs the causes can be numerous, it may be difficult to determine exactly why your cat is shaking. The condition can come on suddenly or gradually, depending on the cause, and it may not happen often, or it may occur more frequently.

Shaking in an adult cat can be generalized, involving the entire body, or more localized, involving the head, tail or other body part. Because shaking can be a very general sign, there can be many reasons for shaking in cats. Over the years I have treated many cats for shaking – whether they were shaking their head, feet, tail, or the whole body, while asleep or when being petted and purring.
