Cat Hyperesthesia Syndrome: Understanding Feline Pain

How feline hyperesthesia syndrome causes distressing episodes in cats and what management approaches can improve their welfare.

Key Facts

Feline hyperesthesia syndrome (FHS) causes episodes of skin rippling, tail chasing, and apparent pain along the spine
It may represent a form of focal epilepsy, obsessive-compulsive disorder, or a pain-sensitisation syndrome
Episodes can be triggered by touch, stress, or occur spontaneously, causing significant distress
Anticonvulsants, antidepressants, and gabapentin have all shown some effectiveness in managing FHS
Environmental stress reduction is an important component of management alongside medical treatment

Welfare Considerations

Feline hyperesthesia syndrome is a distressing and poorly understood condition that causes cats to experience apparent pain, sensory disturbance, or compulsive behaviour in episodic bouts. During episodes, affected cats may cry out, scratch or bite at their flanks and tail, appear frantic, and be difficult to calm. Between episodes they may appear entirely normal, making diagnosis challenging. The welfare burden of this condition is significant — cats experiencing frequent episodes live with a pattern of unpredictable distress that affects their overall quality of life. Management requires careful observation, veterinary investigation to rule out physical causes, and often a multimodal approach combining medication with stress management.

What You Can Do

Video your cat during episodes to share with your vet for accurate diagnosis
Discuss FHS with a veterinary neurologist or dermatologist if your regular vet is uncertain about the cause
Reduce environmental stress triggers including new animals, schedule changes, and perceived threats
Try gabapentin or other veterinary-prescribed medications if environmental management alone is insufficient
Keep an episode diary tracking frequency, duration, and potential triggers to monitor treatment response
