Feline Hyperesthesia: Twitching Skin, Tail Chasing and Causes

By Tailwisp Editorial TeamUpdated October 20, 20264 min read

Few feline problems are as puzzling as the cat that suddenly twitches its back, spins around to bite its tail and bolts across the room as if something had touched it. Owners wonder whether it is pain, itch, fear or something neurological. The honest answer is that nobody knows for certain, and the condition is a diagnosis of exclusion.

What it looks like

Episodes vary, but may include:

• Rippling, rolling or twitching of the skin along the back, near the base of the tail.
• Sudden, frantic licking or biting at the back, flank or tail.
• Tail chasing and attacking.
• Dilated pupils, and a glazed look.
• Sudden running or leaping, as if startled.
• Loud crying, hissing or growling.
• Sensitivity to touch along the back.
• Self-injury, including hair loss and wounds.
• Afterward, the cat may seem normal.

Episodes may last seconds to minutes, and happen daily or occasionally.

Possible causes

Because the signs are non-specific, many conditions need to be considered:

• Skin problems, such as fleas, mites or allergies. See fleas on cats and cat skin allergies.
• Pain, from the spine, nerves, anal glands or muscles. See signs of pain in cats.
• Nerve disease, or spinal problems.
• Seizure-like disorders, such as partial seizures. See seizures in cats.
• Behavioral issues: stress, anxiety, conflict or compulsive disorders. See why do cats overgroom.
• Muscle disease.
• Hyperthyroidism, and other illnesses.
• Oriental breeds such as Siamese, Burmese, Himalayan and Abyssinian seem more commonly affected, which suggests a genetic role.

Veterinary workup

Your vet will take a history, examine your cat, check the skin and back for fleas, mites and sore spots, and perform neurological and orthopedic exams. Tests may include bloodwork, skin tests, X-rays of the spine and, if needed, MRI. A trial of flea control is common. Your vet may suggest a behavior consult.

Treatment

Treatment depends on the findings:

• Treat any cause found, such as fleas, allergies or pain.
• Reduce stress and boost enrichment. See indoor cat enrichment ideas and how to calm an anxious cat.
• Medication. Where no cause is found, vets may try anti-anxiety medications, such as fluoxetine or gabapentin, or anti-seizure drugs such as phenobarbital, under close supervision.
• Pheromones. Some owners use them, though evidence is mixed. See do cat pheromone diffusers work.
• Protect against self-injury, with a soft cone if needed.

Never give your cat any medication without veterinary guidance.

Home care

• Keep a video diary of episodes, with notes on time, triggers and duration. Triggers may include touch, noise, a stressful event or the time of day.
• Keep routines steady.
• Avoid stroking the back during sensitive periods.
• Provide play, climbing and hiding places.
• Reduce conflict among cats. See setting up a multi-cat home.
• Monitor skin for wounds.

Outlook

Some cats improve with environmental changes and treatment, while others have episodes for life. Many cats live happily with careful management.

What to record during an episode

If you can do so safely, take a video of the episode, including the whole body and the face. Record the time of day, how long it lasts, what happened just before and how your cat acts afterward. Note whether touching the back triggers it. Keep this diary for a few weeks, and show it to the vet. Videos are far more useful than descriptions, since cats are rarely doing it in the exam room.

Is it a seizure?

Some episodes look like focal seizures, with dilated pupils, loss of awareness, drooling and sudden movements. If your cat does not respond to its name during an episode, loses control of its bladder or stays groggy afterward, mention it. A neurologist can help decide. See seizures in cats.

Medication and monitoring

If a vet prescribes medication, follow the plan and report any side effects. Some drugs need blood tests to monitor safety. Give medicines at the same times each day. Do not stop suddenly, since that can cause rebound problems.

Prevention of self-injury

If your cat damages its skin, use a soft cone or recovery suit, and keep the nails trimmed. See how to trim cat nails. Clean wounds, and watch for infection.

Environment and routine

A predictable environment lowers stress. Provide high perches, hideaways, daily play and quiet rest. Avoid sudden changes. For multi-cat homes, make sure that every cat has its own resources.

When to see a vet

See a vet if your cat has twitching skin, frantic grooming or self-injury. Use the US vet directory to find a clinic.
