Why Is My Cat Shaking? Signs That Need Veterinary Care

First describe the movement rather than naming a disease

A deliberate head shake is different from an involuntary head tremor. Repeated head shaking can accompany ear irritation, while a sudden uncontrollable head tremor needs an emergency appointment. Tell the clinic whether the movement involves the head, one area, or the whole body, and whether your cat seems aware of its surroundings.

Describe the beginning, the duration, and what happened afterward. Was the cat standing, resting, or interacting with someone? Did it stop moving normally or fall? If you cannot tell whether a movement was voluntary, say so. You do not need to identify a seizure or a neurologic disorder before calling. A precise observation is more useful than confidently applying a label that may not fit.

Look for urgent changes and contact the clinic early

VCA describes seizure appearances ranging from subtle altered awareness and shaking to collapse with jerking movements. Repeated seizures or a prolonged episode require emergency attention; a seizure lasting five minutes is a life-threatening emergency. Contact an emergency veterinarian when a seizure-like episode begins rather than waiting to see whether it reaches that duration.

Tell the team immediately if the cat collapses, is not responding normally, or has repeated episodes without returning to its usual state. Mention abnormal breathing or inability to walk as well. If the movement has already ended, explain how the cat is behaving now and ask about examination. Do not assume that looking normal between episodes establishes that the problem has resolved or that further assessment is unnecessary.

Keep the surroundings safe without putting anything in the mouth

During a suspected seizure, VCA advises preventing injury from falls or objects while avoiding fingers or objects in the cat’s mouth. Cats do not need their tongues pulled forward. Contact the emergency team for instructions and keep people from crowding the animal as you make the area safer.

Time the episode if you can do so without delaying the call. A short video may help the veterinarian understand what you saw, but getting care takes priority over obtaining footage. Do not provoke the movement, force the cat to walk, or administer a remedy while it is not responding normally. Ask the clinic how to move and transport the cat safely if it wants you to come in.

Move your cat to the clinic in a secure cat carrier, and once home give it a quiet, low cat bed away from heights.

Report possible exposures immediately

VCA includes toxin exposure among possible seizure causes and asks about recent medications, supplements, and parasite products during the history. Pet Poison Helpline stresses that suspected poisoning needs an immediate call, since signs vary widely with the substance. Tell the professional about possible access even if you did not witness swallowing.

For a possible exposure, contact your veterinarian, ASPCA Animal Poison Control at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661. A consultation fee may apply. Have the product name, label, timing, and estimated amount available if known. Do not wait to identify a matching symptom on a poison list, and do not give a home treatment unless the professional handling the case specifically directs it.

Repeated head shaking may point to an ear problem

Merck notes that cats often scratch at their ears or shake their heads because of an ear infection, and lists ear mites and other skin conditions among outer-ear problems; injury and foreign material are other possibilities. Report scratching, rubbing, unusual odor, visible discharge, or a change in balance. The signs can help guide examination but cannot establish which problem is present.

Arrange a veterinary appointment when head shaking increases rather than repeatedly trying different ear products. Tell the clinic about any cleaner or medication already applied, including when it was used. Do not insert tools or try to retrieve an object from the ear yourself. If head movement becomes uncontrollable, the cat loses balance, or other signs develop, call again and explain the change so the team can reassess urgency.

The examination and follow-up depend on the pattern

Merck explains that neurologic assessment considers mental activity, head posture, reflexes, coordination, and walking. Blood tests can help identify metabolic problems, and imaging or other investigations may be appropriate in selected cases. Your veterinarian chooses tests based on the examination and history; a movement seen at home does not determine which test is necessary.

Bring a record of episodes and current prescriptions, including recent changes, and ask what to track next. Clarify which findings would require emergency reassessment and when results or a recheck are expected. If treatment is prescribed, follow its instructions and contact the clinician about difficulties or further episodes. Do not adjust or abruptly stop an existing prescription because you suspect it is connected to shaking; ask the prescribing veterinarian how to proceed.
