What it is
A cat's ear canal bends on its way to the eardrum, which makes it warm, dark and a good place for trouble to settle. When something upsets its balance, such as mites, an allergy, a grass seed or too much wax, the skin of the canal swells and germs that are normally few start to multiply.
An infection that stays in the outer canal is mainly a matter of itch and discomfort. If it reaches the middle or inner ear, a cat may tilt its head, lose its balance or walk in circles, because that part of the ear helps it know which way is up.
Itchy ears can make a cat scratch hard enough to leave scabs behind them. A quick look into the ears while you stroke your cat, checking colour, discharge and smell, helps you spot a change early.
Signs you may notice
- Shakes its head
- Scratches its ears
- Dark discharge in the ear
- Red or swollen ear
- Unpleasant smell from the ear
- Tilts its head
A cat shakes its head, scratches its ears or holds one ear lower. Inside the ear you may see dark discharge, redness or swelling, and notice an unpleasant smell.
When to see a vet
Book a visit if your cat shakes its head, scratches its ears or you see discharge. If it suddenly tilts its head, loses its balance or walks in circles, contact a vet the same day.
