Why is my cat scratching their ears?
Repeated ear scratching can reflect mites, infection, allergy, foreign material or other ear and skin disease. Avoid cotton swabs, peroxide, oils and leftover drops; protect the ear from self-injury and arrange examination before treatment obscures the cause.

✓ Prevent self-injury if possible and arrange an ear examination before adding cleaners or drops.
✓ Loss of balance, severe pain, bleeding, head tilt or rapid worsening needs same-day advice.
✓ This information supports observation and does not replace veterinary diagnosis.
Note which ear, how often, and whether there is redness, debris, hair loss or skin damage. This guide explains what to record, what not to do and when veterinary care becomes urgent.
Describe which ear and how often
Note whether scratching affects one ear or both, whether the cat also shakes or tilts the head and when the pattern began. Photograph redness, crust, hair loss or visible outer-ear debris without pulling or probing the canal. A short video may show intensity, but do not trigger scratching or delay care to collect evidence.
Look for clues beyond dark debris
Ear mites may cause intense itching and dark material, but infection, allergy, polyps, foreign material and masses can produce overlapping signs. Colour or smell alone cannot identify the cause, and one-sided persistent disease deserves particular attention. Other household pets may need assessment when parasites or contagious skin disease is suspected.
Put nothing into an unexamined ear
Do not use cotton swabs, peroxide, alcohol, essential oils, vinegar, human ear medicine or leftover veterinary drops. Some products can irritate tissue, push material deeper or be unsafe if the eardrum is damaged. Keep the ear dry and allow the veterinarian to collect useful samples before cleaning whenever possible.
Limit self-injury without wrestling
Keep the cat indoors, trim only clearly overlong nail tips if this is already a calm routine and ask the clinic whether a protective collar is appropriate. Do not bandage the head or repeatedly hold a painful ear. Scratching can create wounds or an ear-flap swelling, so bleeding, rapid swelling or severe distress deserves prompt advice.
Arrange an ear examination
The veterinarian may examine the canal and eardrum and test debris for mites, yeast or bacteria before choosing treatment. Deep pain or a blocked canal may require sedation for a safe complete examination. Use the prescribed product, amount and duration exactly; a dog flea or ear product can contain ingredients that are dangerous to cats.
Escalate balance and neurologic signs
Head tilt, falling, circling, abnormal eye movements, vomiting, facial weakness, inability to stand or severe pain can indicate deeper ear or neurologic involvement and needs urgent assessment. Call ahead and transport in a padded secure carrier on the floor. Do not clean the ear first or wait for the scratching itself to stop.

Common mistakes
×Waiting for a dramatic symptom instead of noticing smaller changes from the cat’s normal routine.
×Changing several things at once, making it difficult to learn what actually helped.
×Treating general guidance as a substitute for advice from a veterinarian who knows the individual cat.

A broken cat tooth may expose sensitive tissue or hide damage below the gumline even when the cat still eats. Prevent hard chewing, do not test or file the tooth and arrange a veterinary dental assessment; facial trauma, jaw misalignment or heavy bleeding is urgent.
