Feline Hyperesthesia Syndrome (FHS)

Feline Hyperesthesia Syndrome (FHS) is a complex little understood condition characterized by behaviours indicative of abnormal skin sensations, such as rippling skin, vocalization, and, in severe cases, self-inflicted tail injuries. Most veterinary neurologists regard FHS primarily as a maladaptive pain disorder, with environmental and emotional factors like frustration and anxiety intensifying clinical signs. Accurate diagnosis requires ruling out dermatological and other pain-related conditions while avoiding misdiagnosis due to overinterpretation of normal feline behaviours or aversion to handling. However, it is important to note that severe tail trauma is never normal behaviour.  

Management focuses on identifying triggers, reducing environmental stress, ensuring access to the five feline essential resources, and, in severe cases, incorporating neuropharmacological treatments such as gabapentinoids or fluoxetine. With a comprehensive and systematic approach, affected cats can achieve a favourable prognosis. 

FHS Treatment Algorithm

The FHS Treatment Algorithm provides a structured framework for veterinary surgeons managing Feline Hyperesthesia Syndrome (FHS). It highlights a multimodal approach, incorporating environmental modifications to minimize stress, ensuring access to essential feline resources, and addressing triggers. The algorithm also includes guidance on pharmacological interventions, presented in a clear and systematic manner. Importantly, all medications must be prescribed by a veterinary surgeon in accordance with national guidelines, with caregivers fully informed about potential side effects and the need for ongoing monitoring. 

Epidemiology Study – can you help?

Do you have or treat a cat affected by Feline Hyperesthesia Syndrome (FHS)? Your experience can contribute significantly to advancing our understanding of this mysterious condition. This research study from the University of Surrey invites cat owners to participate in an ongoing study aimed at uncovering the underlying causes, effective treatments, and long-term outcomes of FHS. By sharing insights, case histories, and observations, participants can help build a comprehensive knowledge base that could lead to better diagnostic tools and management strategies. This collaborative effort is vital for improving the quality of life for cats affected by FHS and for guiding future veterinary care.
