Diagnosing FHS involves excluding other illnesses, and treatment strategies focus on alleviating symptoms and enhancing a cat’s quality of life. A holistic approach, including medications, behavior modification techniques, and environmental enrichment, can collectively contribute to fostering a happy and healthy life for cats grappling with FHS.

Understanding Feline Hyperesthesia Syndrome

Overview of Feline Hyperesthesia Syndrome

Feline Hyperesthesia Syndrome (FHS) is a rare condition in cats where they are overly sensitive to touch, especially on their lower back area. This condition, also known as “rolling skin disease” or “twitchy cat syndrome,” can cause discomfort and distress for affected felines. While FHS can occur in any breed of cat, Asian breeds such as Siamese, Burmese, Abyssinian, and Persian are more prone to developing this syndrome.

Causes of Feline Hyperesthesia Syndrome

Nerve disorders

One potential cause of FHS is related to nerve disorders. Cats with this condition may experience abnormal nerve sensations, resulting in heightened sensitivity and discomfort when touched. The exact mechanisms behind nerve dysfunction in FHS are still not fully understood and further research is needed to uncover the specific details.

Obsessive-compulsive behaviors

Obsessive-compulsive behaviors can contribute to the development of FHS in cats. These behaviors can manifest as excessive grooming, repetitive movements, and a heightened state of arousal. The repetitive self-directed behaviors can lead to increased tactile sensitivity and skin sensitivities.

Changes in neurotransmitters

Alterations in neurotransmitters, the chemical messengers in the nervous system, may play a role in the development of FHS. Imbalances in neurotransmitter levels, particularly serotonin and dopamine, have been associated with various psychiatric and neurological conditions in humans and animals. These imbalances could potentially contribute to the hypersensitivity and abnormal skin reactions observed in cats with FHS.

Underlying epilepsy

There is evidence to suggest that cats with FHS may have an underlying form of epilepsy. Epilepsy is a neurological condition characterized by recurrent seizures. FHS-related seizures can occur spontaneously and vary in intensity and frequency. Further research is necessary to establish the relationship between FHS and epilepsy, as well as the potential mechanisms linking the two conditions.

Skin allergies

In some cases, FHS may be triggered by skin allergies. Allergies can cause inflammation and irritation of the skin, leading to increased sensitivity and discomfort. Cats with FHS may experience exacerbated symptoms when exposed to certain allergens, further exacerbating their condition. Identifying and managing any underlying allergies can be essential in effectively treating FHS.

Understanding Feline Hyperesthesia Syndrome: Causes, Symptoms, and Treatment

Symptoms of Feline Hyperesthesia Syndrome

Sensitivity to touch

One of the primary symptoms of FHS is heightened sensitivity to touch, especially along the back and hindquarters. Cats may react strongly, often exhibiting discomfort or pain when touched in these areas. Normal grooming or petting can trigger an intense response, causing the cat to react defensively or attempt to escape the stimulus.

Rippling or twitching skin

Another noticeable symptom of FHS is rippling or twitching of the skin along the cat’s back. These involuntary muscle contractions can occur spontaneously or in response to touch or stimulation. The rippling or twitching can be subtle or more pronounced, depending on the individual cat and the severity of their condition.

Excessive licking or grooming

Cats with FHS may engage in excessive licking or grooming behaviors. This excessive self-grooming can be a way for the cat to soothe themselves and alleviate discomfort. However, the constant licking and grooming can lead to skin irritation and further exacerbate the symptoms of FHS.

Tail chasing or attacking

FHS can also manifest as tail chasing or attacking behavior in some cats. The cat may become fixated on their tail, chasing it in an attempt to relieve their distress. In severe cases, the cat may even attack their own tail, causing self-inflicted injuries.


Vocalization is a common symptom seen in cats with FHS. Affected cats may yowl or cry out, especially when they are touched or experiencing heightened sensitivity. These vocalizations can range from mild moans to loud, distressed cries.

Running around frantically

Some cats with FHS may exhibit frenzied behavior, such as darting around the room or jumping erratically. This frantic activity can be a response to the discomfort and sensitivity experienced by the cat. It is important to create a safe environment for these cats to prevent injuries during these episodes.


In more severe cases, FHS can be accompanied by seizures. Seizures are abnormal electrical discharges in the brain, resulting in a range of symptoms, including convulsions, loss of consciousness, and muscle rigidity. Seizures associated with FHS can vary in frequency and severity, and it is crucial to seek immediate veterinary care if a cat experiences a seizure.

Diagnosis of Feline Hyperesthesia Syndrome

Excluding other illnesses

Diagnosing FHS involves ruling out other potential medical conditions that can present with similar symptoms. Skin infections, allergies, arthritis, and other neurological disorders must be considered and eliminated through thorough testing and examination.

Physical examination

A physical examination is an essential step in diagnosing FHS. The veterinarian will carefully assess the cat’s overall health, paying close attention to any abnormalities, skin conditions, or signs of discomfort. They may also conduct a thorough evaluation of the cat’s reflexes, muscle tone, and overall neurological function.

Neurological evaluation

A neurological evaluation is commonly performed to assess the cat’s nerve function and rule out other possible neurological conditions. This evaluation may involve assessments of the cat’s balance, coordination, and responses to specific stimuli. Neurological tests, such as a spinal tap or brain imaging, may be recommended in some cases to gather further diagnostic information.
