A cat who suddenly holds the head to one side may have a problem with the balance system, called the vestibular system. This sign is sometimes described as torticollis or a head tilt. It can occur with inner-ear disease, inflammatory polyps, neurologic disorders, or an idiopathic vestibular episode. A new head tilt needs a prompt veterinary examination.
What other signs may occur?
Loss of balance, falling, circling, rapid side-to-side eye movements, nausea, vomiting, and reluctance to walk may accompany a head tilt. Some cats appear frightened because their sense of balance is suddenly disrupted.
When is it an emergency?
Seek emergency care if your cat cannot stand, has seizures, becomes unresponsive, has difficulty breathing, or shows severe weakness. A sudden head tilt with marked balance loss also warrants urgent assessment because serious causes can resemble benign vestibular disease.
Possible causes
Middle or inner ear infection, inflammatory polyps, medication reactions, trauma, and disease affecting the brain are among the possibilities. Sometimes no cause is found, and the condition is termed idiopathic vestibular syndrome. That diagnosis should not be assumed without examination.
How veterinarians investigate
The veterinarian may examine the ears, eyes, gait, and neurologic function. Depending on the findings, blood tests, imaging, or further ear evaluation may be recommended. Treatment targets the cause and may include supportive care for nausea and safe mobility.
Keeping your cat safe while arranging care
Confine your cat to a quiet, padded space without stairs or high furniture. Use a carrier for transport and minimize handling. Do not put leftover ear drops into the ear, force food, or give human motion-sickness medicine without veterinary advice.

Frequently asked questions
Will a head tilt go away?
Some vestibular episodes improve, but the cause determines treatment and prognosis. An examination is important.
Can an ear infection cause a head tilt?
Yes, particularly if the middle or inner ear is involved.
Is a head tilt always a stroke?
No. Several conditions can cause it, and a veterinarian must distinguish them.
