Feline Hyperesthesia Syndrome (FHS): What You Need to Know

Are you a cat owner that has noticed your furry feline acting unusually twitchy, biting itself, or excessively grooming? If so, your cat may be suffering from feline hyperesthesia syndrome (FHS), commonly known as rolling skin disease or twitchy cat syndrome.

FHS is a poorly-understood disorder that can cause pain, distress, and discomfort in cats. Let’s dive into what FHS is, its symptoms, treatment options, and other important factors to be aware of.

What is Feline Hyperesthesia? FHS is a neurological disorder that causes a cat’s skin to roll, twitch, or ripple.

This can be accompanied by signs of paranoia, excessive grooming, tail chasing, self-mutilation, biting, vocalizing, and visible signs of pain. Typically, FHS happens in episodes and may last from a few minutes to over an hour.

After an episode, the cat may retreat to a corner or act abnormally for a certain period. In rare cases, seizures have been reported as a result of FHS.

Symptoms of FHS

One of the most noticeable symptoms of FHS is excessive grooming, where the cat constantly licks its fur or chews on it. Tail chasing, biting, and self-mutilation are also common symptoms.

The cat may vocalize, twitch, and feel pain, which is often the cause of aggressive behavior. Additionally, some cats may show signs of paranoia or anxiety during an episode.

If you notice your cat experiencing any of these symptoms, it is essential to consult your veterinarian to rule out other potential illnesses.

FHS Episodes

The timing and duration of FHS episodes can vary from cat to cat. Episodes occur in sudden spurts and can happen at different intervals.

Short episodes can last a few seconds to a few minutes, while more severe episodes can last over an hour. During an episode, the cat may become aggressive or detached; however, after an episode, the cat may become withdrawn, sleepy, or act abnormally.

It is essential to observe your furry feline during an episode and after one to gain a better understanding of its behavior.

Diagnosis and Treatment of FHS

Since FHS is a poorly-understood disorder, it can be challenging to diagnose. Your veterinarian will perform a dermatologic workup, including a complete blood count, urinalysis, and chemical profile to rule out other potential illnesses.

A neurological examination will evaluate your cat’s brain function and any signs of nerve damage. Following that, a medication trial or prescription program may be implemented to alleviate the cat’s symptoms before experimenting with behavior modification methods.

Lack of Understanding and Diagnosis of FHS

FHS is an underdiagnosed disorder that often goes unnoticed. Due to the limited understanding of FHS and the similarities in symptoms with other illnesses, it can be challenging to diagnose.

Additionally, the age of onset and breed susceptibility seem to be significant factors in FHS, mainly affecting young adult cats and certain breeds such as Siamese and Burmese.

Painful Effects of FHS on Cats

FHS can be extremely painful for cats, causing a range of symptoms and behaviors that indicate distress and discomfort. They may show signs of aggression, self-mutilation, and excessive grooming, which can cause further damage to their skin and fur.

The pain and discomfort that accompany FHS can have a severe impact on a cat’s overall health and well-being. Therefore, it’s crucial to seek veterinary assistance if you notice symptoms of FHS.


Feline hyperesthesia syndrome is a poorly-understood neurological disorder that causes a range of symptoms, including episodes of rolling skin, twitching, biting, and self-mutilation, among others. Diagnosis and treatment of FHS can be challenging due to the limited understanding of the disorder, but medication trials and behavior modification programs can be helpful in easing a cat’s symptoms.

By being aware of the symptoms and potential triggers, cat owners can minimize the negative impact FHS can have on their feline friends.

Importance of Veterinary Care for Feline Hyperesthesia Syndrome (FHS)

Feline hyperesthesia syndrome (FHS) can be a challenging condition to manage and treat. It requires veterinary care to ensure a proper diagnosis, appropriate treatment plan, and ongoing monitoring.

In this section, we will discuss why veterinary care is essential for FHS, the importance of a vet consultation, and the various treatment options available.

Importance of Veterinary Consultation

If you notice your cat displaying any signs of FHS, it is crucial to schedule a veterinary consultation. The veterinarian will perform a thorough physical exam, which includes a full dermatologic workup, neurological examination, and pain examination to diagnose the condition.

They will also rule out any underlying conditions that could cause similar symptoms, such as allergies or infections. Since FHS is a challenging condition to diagnose, it’s important to have a veterinary professional involved in your cat’s care.

Behavior Modification and Management

Following a diagnosis, the veterinarian will create a tailored treatment plan that may include behavior modification strategies and management techniques. Behavior modification focuses on identifying and addressing potential triggers that could cause FHS episodes.

For example, stress or changes in the cat’s environment may cause an episode. Management techniques involve making environmental changes that can help reduce the occurrence of FHS episodes.

Common techniques include providing toys that can help distract the cat, reducing environmental stressors, and providing a calm and quiet space for the cat.

Medication for FHS

In some cases, medication may be recommended to alleviate the cat’s symptoms and provide relief. Medications that may be used to treat FHS include flea medications, corticosteroids, anticonvulsants, and anti-anxiety drugs.

Flea medications are often used in case of flea-bite hypersensitivity, which may cause FHS in cats. Topical cetirizine may be recommended to help minimize the urge to scratch.

Corticosteroids may be used to help reduce inflammation and itching associated with FHS. Anticonvulsants such as gabapentin may be prescribed to help control seizures or twitching.

Low doses of anti-anxiety drugs may also be used to help manage stress and anxiety associated with FHS.

No Cure for FHS

There is no cure for FHS, making it a long-term condition. However, with proper veterinary care, behavior modification, and medication, FHS can be managed effectively.

It’s essential to work closely with your veterinarian to ensure your cat receives appropriate treatment for their condition. Your veterinarian can also monitor your cat’s condition and adjust the treatment plan as necessary to ensure your cat’s long-term health and well-being.

In conclusion, veterinary care is crucial for the diagnosis, treatment, and ongoing management of FHS. Veterinary professionals can provide behavior modification strategies, management techniques, and medication that can effectively manage FHS symptoms.

While there is no cure for FHS, with appropriate veterinary care, cats diagnosed with FHS can lead healthy and happy lives. If you suspect your cat may be exhibiting symptoms of FHS, we highly recommend scheduling a veterinary consultation to get a proper diagnosis and treatment plan.

In conclusion, Feline Hyperesthesia Syndrome (FHS) is a challenging condition that requires veterinary care for proper diagnosis, treatment, and ongoing management.

Symptoms of FHS include excessive grooming, tail chasing, self-mutilation, biting, vocalizing, pain, and twitching.

Veterinary professionals can perform dermatologic workups and neurological examinations to diagnose FHS and prescribe medications such as anticonvulsants, anti-anxiety drugs, and corticosteroids to alleviate symptoms. While there is no cure for FHS, behavior modification and management, in combination with medication, can effectively manage symptoms.

If you suspect your cat may be experiencing symptoms of FHS, seek veterinary care to ensure proper diagnosis and treatment.
