Learn more about ear infections in cats
Just like in humans, ear infections in cats can be painful. They’re often caused by germs like bacteria and yeasts. Common triggers include ear mites and allergies.
Ear infections are less common in cats than dogs, but when they have one, it can be for different reasons:
wax building up and incorrect ear cleaning
ear mites
excessive growth of bacteria, yeast or both
allergies (fleas, pollen, food, etc)
irritants in the environment
foreign bodies into ear canal
polyps or tumours into the ear canal
immuno-system diseases (FELV, FIV)
autoimmune diseases
rupture of the ear drum
A simple outer ear infection can quickly spread to the middle ear and onto your cat's inner ear, which is why it is essential to seek treatment for your cat's ear infection as soon as symptoms arise. If left untreated, ear infections in cats can result in hearing loss.

Symptoms of Ear Infections in Cats
Look out for signs like head shaking, scratching at ears, red or swollen ears, waxy buildup, discharge, or an unpleasant smell. Deeper infections may cause a head tilt, loss of balance, or eye flicking.
When to contact your vet
Ear infections are painful, so contact your vet as soon as you notice the problem, as if left untreated, it can lead to permanent damage to the ear.
Diagnosis of Ear Infections in Cats
A vet examines the outer ear for signs of infection or injury. An otoscope is used to inspect the ear canal for swelling, discharge, or foreign objects. Swabs may be taken for severe infections to identify specific germs. Sedation may be needed for a thorough exam, especially if your cat is in pain.
Treatment of Ear Infections in Cats
Cleaning your cat’s ears with a veterinary strength cleaner is crucial
Topical ear drops may be prescribed to treat bacteria, yeasts, and inflammation
Anti-inflammatory and pain relief by mouth if your cat is very painful in addition to ear drops
Follow-up checks are essential to ensure a complete recovery
Prevention of Ear Infections in Cats
Regular parasite control is recommended to prevent ear mites. Check your cat’s ears regularly for any issues and use vet-recommended ear cleaners. Avoid inserting anything into the ear canal. If your cat has allergies, ensure they are well-controlled through diet or medication as advised by your vet.
How to clean your cat’s ears
Find a comfortable area and position for you and your cat. You might need the help of someone else to hold your cat on and non-slipper surface while you clean his/her ears.
You will need the vet-approved ear cleaner, some gloves and some cotton wool.
Place the nozzle of the ear cleaner into the ear (not too deep) and squeeze it.
Gently massage the base of your cat’s ear for a few seconds to allow to loosen and break down hard wax. Then, allow your cat to shake their head.
After your cat shakes out the excess cleaner, gently wipe their ear flap and opening of their ear canal with a cotton ball or with your finger wrapped in gauze. Never use cotton buds as they can push wax even further in and there is also a risk of perforating the ear drum.
Repeat these steps with your cat’s other ear.
Outlook
Nearly all ear infections in cats that are diagnosed and treated can be cured. However, if an underlying cause remains unidentified and untreated, the outcome will be less successful.
