Research overview: vestibular disease and balance disorders in cats

When the vestibular system malfunctions, cats can show dramatic signs of imbalance, and studying these disorders illuminates how the balance sense normally works. This overview surveys feline vestibular disease, which can cause head tilt, loss of balance, abnormal eye movements, and disorientation, sometimes appearing idiopathically, especially in older cats. The signs reflect disruption of the inner-ear or central vestibular pathways that normally provide stable orientation. The survey relates these clinical presentations to the structures of the vestibular system and to the integration of balance with vision and posture. It discusses how many cases of idiopathic vestibular disease improve over time. Understanding vestibular disease shows what happens when the cat's finely tuned balance organ fails. It underscores the importance of the vestibular system by revealing the striking effects of its disruption, and it connects normal sensory biology to the recognition and care of balance disorders in cats.
