When your cat starts shaking her head more than usual, something’s off. If she’s scratching at her ears with frustration, it’s a clear sign something’s bothering her. And often, the culprit is hiding in plain sight. Where? Inside the ear.
A cat ear infection might not sound alarming at first. However, it can escalate into a dangerous condition if left unchecked. This is why recognizing the early signs, understanding the causes, and knowing how to treat ear infections in cats is essential.
Let’s take a deep dive into this common feline health issue.
What Is a Cat Ear Infection?
A cat ear infection, clinically known as otitis, is an inflammation of the ear canal. It may be limited to the outer ear (otitis externa), or it may affect the deeper structures like the middle (otitis media) or inner ear (otitis interna).
While infections in cats are less frequent than in dogs, they’re often more complex when they do occur.
The deeper the infection travels, the more serious the consequences. Balance issues, hearing loss, and neurological symptoms can develop in advanced cases. That’s why early identification and treatment are key.
How to Tell If Your Cat Has an Ear Infection
Unlike dogs, cats are often masters of masking pain. But when their ears are inflamed or infected, they’ll leave clues. Subtle at first, then increasingly hard to ignore.
Common symptoms of a cat ear infection include:
Frequent head shaking or tilting
Scratching at one or both ears
Redness, warmth, or visible swelling
Foul odor emanating from the ear canal
Discharge (yellow, brown, or black, often waxy or gritty)
Sensitivity or pain when touched near the ears
Hearing loss or disorientation
Changes in behavior like hiding, irritability, or seeming "off"
If you’re noticing more than one of these signs, your cat may be dealing with more than just a little earwax buildup.
Types of Cat Ear Infections: Otitis Externa, Media, and Interna
Not all ear infections are created equal. Here's a breakdown:
Type of Otitis | Area Affected | Common Symptoms | Severity |
Otitis Externa | Outer ear canal | Redness, itching, waxy discharge | Mild to moderate |
Otitis Media | Middle ear | Head tilt, hearing loss, balance issues | Moderate to serious |
Otitis Interna | Inner ear | Circling, nausea, neurological signs | Severe |
In most cases, infections typically begin in the outer ear and can spread inward if left untreated. But when we intervene promptly, recovery is typically smooth.
What Causes Ear Infections in Cats?
A cat ear infection is never “just” an infection. It’s a symptom of something else going wrong. Some common culprits include:
1. Ear Mites
Microscopic pests that cause intense itching and dark, crumbly debris. Common in kittens and outdoor cats.
2. Bacterial or Fungal Infections
Bacterial and fungal infections often arise from a disrupted ear environment, whether from allergies, excess moisture, or poor hygiene.
3. Allergies
Food sensitivities or environmental triggers (like dust or pollen) can cause chronic inflammation in the ears.
4. Foreign Bodies or Trauma
A grass seed, a small insect, or even overzealous cleaning can trigger irritation and infection.
5. Underlying Conditions
Hormonal imbalances, tumors, or immunodeficiencies (like FIV) can predispose a cat to recurring infections.
Which Cats Are More Susceptible to Ear Infections?

Some cats are more prone to developing ear issues, whether due to their breed, environment, or underlying health conditions. Knowing this can help you stay one step ahead.
Here are the most commonly affected groups:
1. Scottish Folds and Other Folded-Ear Breeds
Their signature folded ears create a narrower canal, which can trap wax and moisture more easily, creating a perfect storm for bacteria or mites.
2. Persians and Other Long-Haired Cats
Thick fur around and inside the ears can trap dirt, allergens, and debris. Plus, Persians are prone to brachycephalic anatomy, which may affect airflow and self-cleaning mechanisms in the ear canal.
3. Outdoor and Stray Cats
Cats that roam outdoors or have access to gardens, parks, or rooftops are at a much higher risk of ear mites, injuries, and foreign bodies in the ear.
4. Kittens
Young cats, especially rescues or those without regular parasite control, are extremely vulnerable to ear mites. Left untreated, these infestations often lead to secondary infections.
5. Cats With Allergies
Whether food or environment-related, allergies can trigger chronic inflammation in the ears. Repeated flare-ups often result in recurrent infections.
6. Cats With Weakened Immune Systems
Felines with FIV (Feline Immunodeficiency Virus), FeLV (Feline Leukemia), or older senior cats may have reduced immune defenses, making them more vulnerable to recurring infections.
How We Diagnose a Cat Ear Infection at Noble Vet
Identifying the root cause of the infection is crucial for achieving long-term relief. When you bring your cat in, we perform a comprehensive exam that may include:
Visual inspection of the ear and surrounding tissue
Otoscope exam to view the ear canal and eardrum
Microscopic cytology from an ear swab to detect mites, yeast, or bacteria
Culture and sensitivity testing for chronic or stubborn cases
Imaging (X-ray or CT) if we suspect deeper ear involvement or a mass
Each step is gentle and tailored to your cat’s comfort, providing us with the information needed to treat effectively.
How to Treat a Cat Ear Infection
Treatment depends on what is causing the infection and how deep it has progressed. Here’s how we approach care at Noble Vet:
1. Ear Cleaning
Before any medication can work, the ear needs to be clean.
We may perform a professional ear flush under light sedation.
For at-home care, we’ll guide you through safe cleaning using vet-approved solutions.
Never use alcohol or hydrogen peroxide. They can cause serious irritation.
2. Topical Drops
Depending on the cause, we prescribe:
Antibiotic or antifungal ear drops
Anti-inflammatory medication to reduce swelling and discomfort
3. Oral Medications
For deeper infections, or if topical treatment alone isn’t sufficient, your cat may need:
Systemic antibiotics
Antifungal pills
Pain relief, especially if the infection is severe
4. Parasitic Treatments
If ear mites are found, we’ll recommend specific products like selamectin or ivermectin, and discuss monthly parasite prevention.
How Long Does It Take for a Cat Ear Infection to Heal?
With proper treatment, most ear infections resolve within 7 to 21 days. But the exact timeline depends on the severity and underlying cause.
What’s important is sticking to the full treatment plan, even if symptoms seem to improve early. Incomplete treatment is a common reason for recurrence.
When to See a Vet Immediately
Some signs point to more serious inner ear involvement. Seek veterinary care without delay if your cat is:
Tilting her head or walking in circles
Showing signs of disorientation
Crying out in pain or acting aggressively
Bleeding from the ear
Experiencing a sudden loss of balance or coordination
Preventing Cat Ear Infections

The best treatment is often prevention. Here’s what you can do:
Check your cat’s ears weekly for redness, odor, or debris
Keep their environment clean and dry
Treat for parasites monthly, especially in the UAE climate
Address food or seasonal allergies with your vet
Schedule regular checkups
“Ear infections in cats are often overlooked until they cause severe discomfort. The key is early detection and tailored treatment, especially in breeds prone to chronic issues or cats rescued from the outdoors.”
