Cat Feline Hyperesthesia Syndrome

Feline hyperesthesia syndrome (FHS) is a poorly understood condition causing apparent hypersensitivity and bizarre behaviour in cats, requiring careful investigation and management.

Key Facts

FHS causes episodes of skin rippling, excessive grooming, self-directed aggression, and apparent hallucinations
The condition is sometimes called rolling skin syndrome or twitchy cat disease
Episodes may be triggered by touch along the back or occur spontaneously
Underlying causes including skin disease, spinal pain, and neurological conditions must be excluded
Anticonvulsants, anxiolytics, and behavioural modification are used with variable success

Welfare Considerations

FHS episodes appear distressing and can result in self-injury through excessive grooming and biting. The unpredictable nature of episodes creates chronic anxiety in some affected cats. The condition has a complex aetiology and may represent a spectrum of different underlying problems. Thorough investigation to identify and treat any contributing medical cause is essential before concluding the problem is purely behavioural or neurological. Pain management is an important consideration.

What You Can Do

Seek full veterinary workup including skin examination and spinal pain assessment
Investigate and treat any skin disease or ectoparasite infestation as possible triggers
Work with a feline behaviourist to identify environmental triggers for episodes
Discuss medication trials with a veterinary specialist for refractory cases
Record episodes on video to share with your vet as episodes may not occur during consultation
