Did you know that feline hyperesthesia, also known as “twitch-skin syndrome” or “rippling skin disease,” affects cats? It causes dramatic skin twitching along their back, sudden grooming, and biting at their back, tail, or flank¹. This behavior, often called cat back twitching, can be puzzling for cat owners. While some twitching is normal, too much could mean a health problem that needs vet care.

It’s important to know the signs of feline hyperesthesia to get the right vet care early. This can greatly improve a cat’s life¹. Cats with hyperesthesia may twitch, scratch, bite, and lick their back, tail, and legs². They might also have other symptoms like a swishing tail, big pupils, salivation, and loud meowing².

The exact reason for feline hyperesthesia is still a mystery. But it’s thought to be linked to the brain, genetics, and the environment¹. Stress, health problems, and some breeds might be more likely to get it¹. A full check-up, including a medical history and physical exam, is key to finding the cause and checking for other problems¹².

What Is Cat Back Twitching?

Cat back twitching, also known as feline hyperesthesia or rolling skin syndrome, is a condition where a cat’s back muscles contract involuntarily. This causes the skin to ripple. It can be confusing for cat owners, as it often happens suddenly without a clear reason. Knowing the signs and symptoms of feline back twitching is key to identifying the issue and getting the right care for your cat.

Defining Feline Back Twitching

Feline back twitching is when a cat’s back muscles have uncontrollable spasms. These spasms mainly affect the spine and lower back. The skin then ripples or twitches, often with other odd behaviors. Feline Hyperesthesia Syndrome (FHS) shows symptoms like skin rippling or twitching, especially on the lower back, along with biting and scratching³.

While any cat can get back twitching, it’s more common in Asian breeds like Siamese, Burmese, Abyssinian, and Persian³⁴.

Common Signs and Symptoms

When a cat has back twitching, you might see these signs:

• Rippling or twitching of the skin, especially on the lower back
• Dilated pupils and a startled expression
• Sudden bursts of frantic activity, such as jumping or running
• Excessive vocalization, including meowing or yowling
• Chasing or swatting at the tail
• Biting, licking, or scratching the lower back, sides, hind paws, or tail
• Sensitivity or discomfort when touched in the affected area
• Tiredness or lethargy following an episode

Cats with Feline Hyperesthesia Syndrome usually start showing symptoms between one and seven years old³. However, this condition can appear without a clear reason. Episodes can happen every few days or almost daily⁴. Spotting these signs is the first step to addressing your cat’s twitching and finding the cause.

Normal Feline Behavior and Back Twitching

Back twitching in cats can sometimes worry us, but it’s often normal. Cats have a special muscle structure and are very sensitive to touch. This can lead to back twitches as part of their natural way of communicating and showing body language.

The Cutaneous Trunci Muscle

The cutaneous trunci muscle is a thin layer of muscle on a cat’s back. It runs from the shoulder blades to the tail base. This muscle is very sensitive and can twitch without warning, especially when touched, excited, or surprised.

When it twitches, the skin on the cat’s back may ripple or quiver. This is a normal reflex action.

Cats’ Sensitivity to Touch

Cats are very sensitive to touch, especially on their backs. This is because their skin has many nerve endings and the cutaneous trunci muscle is very responsive. When a cat’s back is stroked or touched, it may twitch or ripple slightly. This is a natural response and usually not a cause for concern.

Communication Through Body Language

Back twitching can also be a way for cats to communicate. They may twitch their backs to show emotions like pleasure, excitement, or annoyance. For example, a cat enjoying being petted might twitch its back slightly, showing happiness.

On the other hand, if a cat is overstimulated or wants to stop an interaction, it might twitch its back more. This is a signal to stop.

While occasional back twitching is normal, frequent or intense twitching might mean there’s a health issue. For example, feline hyperesthesia syndrome⁵ can cause intense scratching, biting, and licking of the back, tail, and rear legs. Other symptoms include dilated pupils, salivation, and frantic behavior⁵.

Potential Health Issues Causing Back Twitching

Back twitching in cats can sometimes be normal. But, if it happens a lot or is very bad, it might mean there’s a health problem. There are many health issues that can make a cat’s back twitch, from small problems to serious ones that need a vet.

Pain and Discomfort

Pain or discomfort is a big reason for back twitching in cats. Issues like arthritis, abscesses, or nerve damage can cause muscle spasms. Cats often hide when they’re in pain, so watching for changes in their behavior is key.

Skin Diseases and Allergies

Deeper skin diseases can also make a cat’s back twitch. Problems like flea allergy dermatitis can irritate the skin. Allergies to food or grooming products can also cause skin issues and twitching.

Seizures and Neurological Disorders

Back twitching can sometimes mean a cat is having a seizure or has a neurological disorder. Cats with epilepsy might twitch or stare blankly. Feline hyperesthesia syndrome, which affects the nervous system, is common in young cats. Certain breeds like Burmese and Siamese are more likely to get it⁶⁷.

If your cat’s back twitching doesn’t stop or gets worse, see a vet. They can check your cat, do tests, and find the right treatment. This will help your cat feel better and get rid of any health problems.

Feline Hyperesthesia Syndrome (FHS)

Feline hyperesthesia syndrome (FHS), also known as rolling skin disease or twitchy cat syndrome, is a neurological disorder in cats. It causes frantic scratching, biting, or grooming of the back area. The skin in this area may ripple or roll⁸. FHS is rare, but Asian cat breeds like Siamese and Burmese are more likely to get it⁹. Breeds like Abyssinian, Burmese, Himalayan, and Siamese are at higher risk⁸.

The syndrome usually starts in cats after they mature. Most cases begin in cats between one and five years old⁸⁹. Symptoms come in short episodes of one to two minutes⁸. These episodes can happen many times a day or week, often due to different triggers⁸.

Cats with FHS may show signs like skin twitching and excessive grooming. They might also chase their tail, vocalize, and rarely have seizures⁹. Other symptoms include dilated pupils, extreme sensitivity to touch, and erratic behavior. The exact cause is still unknown, but it might be related to nerve disorders or stress⁹.

The lack of pathophysiological knowledge makes diagnosing cats with feline hyperesthesia syndrome extremely complicated, as many of the behaviors associated with the syndrome resemble or are identical to behaviors observed in other feline health disorders⁸.

FHS is diagnosed by ruling out other illnesses⁹. Conditions like Flea Allergy Dermatitis can look similar to FHS⁹. Treatments include behavioral changes, medicines, and alternative medicine⁸. The goal is to manage symptoms and improve the cat’s life, which may include medications and behavior modification strategies⁹.

While FHS can’t be cured, proper care can help cats live well⁹. With the right treatment, cats can have a good quality of life⁸.

Diagnosing and Treating Cat Back Twitching

When a cat’s back twitches, finding the cause is key to effective treatment. Many things can cause this, from stress to health issues. Knowing what might cause it helps owners and vets find the right diagnosis and treatment.

Triggers and Risk Factors

Several things can make a cat’s back twitch. Feline hyperesthesia syndrome (FHS) often starts in cats aged 1 to 4 years¹⁰. Siamese, Burmese, Himalayans, and Abyssinians are most often affected¹⁰. Other possible causes include:

• Dermatological diseases like flea allergic dermatitis, causing intense itching¹¹
• Neurological disorders such as seizures or spinal cord issues like cauda equina syndrome¹¹¹²,
• Toxin exposure to substances like permethrins, avermectins, amphetamines, and bromethalin¹¹
• Psychological conditions, including anxiety, fear, excitement, or obsessive-compulsive disorder¹¹
• Pain or injury leading to muscle tremors or shivering¹¹
• Metabolic issues like hypoglycemia in diabetic cats or young kittens who haven’t eaten¹¹
• Infections such as toxoplasmosis, tetanus, and feline infectious peritonitis (FIP)¹¹

Diagnosis and Treatment Options

Diagnosing cat back twitching involves a detailed process. Vets do a complete neurologic exam, blood work, spinal radiographs, and skin scrapings¹⁰. Since there’s no specific test for FHS, diagnosis is based on patient history and ruling out other causes¹².

Treatment for cat back twitching varies based on the cause and symptoms. Options include:

1. Anti-seizure medications like phenobarbital or gabapentin for neurological issues¹⁰¹²,
2. Behavioral medications such as Elavil or Prozac for psychological conditions¹²
3. Corticosteroids or anti-anxiety drugs to manage stress response and reduce inflammation¹⁰
4. Flea control products and anti-parasite medications to address flea infestation and itching¹¹¹²,
5. Environmental and behavioral modifications to minimize triggers and manage stress¹⁰¹²,

Removing environmental triggers can solve the problem¹⁰. Reducing stress can help, and some cats get better in a new home¹⁰. But, stopping medication often leads to symptoms coming back, making treatment lifelong¹⁰.

There is no one-size-fits-all treatment for feline hyperesthesia syndrome, and finding the most effective approach may require trial and error. If there is minimal or no response to one medication, trying another may be necessary¹².

Working with a vet and identifying triggers can lead to a tailored treatment plan. This improves a cat’s life and reduces the impact of twitching.

When to Seek Veterinary Care

As a cat owner, knowing your cat’s normal behavior and health is key. Sometimes, back twitching is just a normal reaction. But, persistent twitching or other signs need a vet’s check-up for the right diagnosis and treatment.

Severe or Persistent Twitching

If your cat’s back twitching happens often or is very severe, you should see a vet. Twitching that lasts a few seconds to minutes might show a health problem¹³. Your vet will look closely to find out why and suggest the best treatment.

Accompanying Symptoms

Watch for other signs that might mean a bigger issue. These could be:

• Intense scratching, biting, or licking of the back, tail, and rear legs¹³
• Hair loss near the back and tail from too much grooming¹³
• Dilated pupils, salivation, uncontrollable urination, loud vocalizations, and frantic running¹³
• Extreme behavior changes and muscle twitches, possibly from rabies¹⁴
• Itchy and irritated skin from fleas or mites, causing muscle twitching¹⁴

If you see these signs with twitching, see your vet right away. These could mean problems like feline hyperesthesia syndrome, skin allergies, seizures, slipped discs, or pinched nerves¹³.

Importance of Early Intervention

Getting your cat to the vet early for twitching or other symptoms is vital. Early care helps get a quick diagnosis and treatment. This stops the problem from getting worse and makes your cat’s life better. Your vet might suggest medicines, behavior changes, stress reduction, and other treatments to help your cat¹³.

Remember, your vet is your go-to for your cat’s health and behavior worries. By telling your vet all about your cat’s symptoms and history, you help your cat get the best care. This keeps your cat healthy and happy.

Conclusion

It’s important to know why cats twitch their backs. Sometimes, it’s just a normal reaction. But if it keeps happening, it might mean there’s a health problem¹⁵.

Things like pain, skin issues, allergies, seizures, and brain problems can cause twitching¹⁶¹⁷. For example, feline hyperesthesia syndrome (FHS) can make cats very sensitive¹⁶¹⁷.

Knowing the signs of FHS is key. Look for sudden grooming, skin reactions, loud meowing, and hyperactivity¹⁵. Some cats, like Siamese, are more likely to get FHS¹⁷¹⁵.

Getting a proper diagnosis is crucial. It might involve blood tests, biopsies, and scans¹⁶¹⁷.

Treatment for twitching and FHS includes medicine and changing the cat’s environment¹⁶¹⁷¹⁵. Knowing the causes and symptoms helps. And getting vet help early is vital for your cat’s health.
