Cat Feline Hyperesthesia Syndrome Management

Feline hyperesthesia syndrome causes episodes of exaggerated skin sensitivity, self-directed aggression, and distress that significantly affect quality of life.

Key Facts

FHS is characterised by rolling skin, dilated pupils, sudden aggression, and excessive grooming
Episodes are typically brief (seconds to minutes) but can occur multiple times daily
The underlying cause is unknown but may involve pain, obsessive-compulsive disorder, or seizures
Stress reduction and environmental enrichment are first-line management approaches
Some cats respond to anticonvulsants, antidepressants, or anxiolytics

Welfare Considerations

Feline hyperesthesia episodes appear distressing with cats seemingly acting in pain and unable to control their responses. The episodic nature means affected cats may be in significant welfare compromise without owners understanding the pattern.

What You Can Do

Video episodes to show your veterinarian for accurate diagnosis
Reduce environmental stressors and implement enrichment before medication
Avoid handling skin during episodes to prevent redirected aggression
Seek referral to a veterinary neurologist or behaviourist if response is poor
