Do Maine Coons Have Ear Problems? Signs, Causes & What to Watch For

Maine Coons are known for their large, tufted ears – but these distinctive features can sometimes make ear problems harder to spot.

Like all cats, Maine Coons can develop ear issues, but their long fur and dense ear tufts may trap dirt, wax, and moisture, increasing the risk of irritation or infection.

The challenge for owners is that early symptoms are often subtle. A small increase in scratching or head shaking may be the first sign that something is wrong.

Understanding Maine Coon ear problems is essential if you want to:

• Detect issues early before they worsen
• Prevent infections and discomfort
• Maintain overall ear health and hygiene

In this guide, you’ll learn the most common ear problems in Maine Coons, how to recognise symptoms, and the best ways to treat and prevent them.

Recurring ear issues are often linked to broader health or immune factors. For a wider medical overview, see our Maine Coon health and wellness guide.

Common Maine Coon Ear Problems & Key Symptoms

Most Maine Coon ear issues fall into a few common categories. The key difference is how they present:

Ear mites

• Intense scratching
• Head shaking
• Dark, crumbly debris (often described as coffee-ground-like)

Ear infections (Bacterial or Yeast)

• Redness or swelling
• Bad odour
• Yellow, brown, or waxy discharge
• Sensitivity when touched

Wax buildup or irritation

• Mild scratching
• Visible wax inside the ear
• No strong smell (usually)

Allergy-related irritation

• Repeated scratching
• Red or inflamed skin around the ears
• Often linked with skin or grooming issues elsewhere

👉 If symptoms persist, worsen, or include pain or swelling, a vet check is recommended.

When To Be Concerned About Ear Problems

Not all ear scratching is serious, but some signs should never be ignored.

You should monitor closely or seek advice if you notice:

• Frequent or aggressive scratching
• Ongoing head shaking
• Strong or unusual odour
• Visible discharge or swelling
• Behaviour changes (irritability, sensitivity to touch)

These symptoms often indicate an underlying issue that will not resolve on its own.

Why Are Maine Coons Prone To Ear Problems?

Maine Coons have large, wide ears with tufts that help keep debris out. However, their ear canals are deep, making it easy for wax, bacteria, and parasites to build up out of sight.

Outdoor exploration, dense inner ear fur, and allergies can all increase the risk of ear-related issues.

Most Common Ear Problems

Below, we outline the most common Maine Coon ear problems:

1. Ear Mites (Otodectes Cynotis)

Ear mites are microscopic parasites that infest the ear canal, feeding on wax and oils. They are highly contagious and particularly common in kittens or multi-pet households.

Ear mites are caused by contact with infected animals or contaminated bedding.

This condition can be avoided by regularly cleaning your cat’s ears and quarantining new pets.

Symptoms:

• Persistent scratching at the ears
• Black, crumbly earwax (like coffee grounds)
• Head shaking
• Crusty scabs around the ears

Treatment: A veterinarian may prescribe antiparasitic ear drops (e.g., selamectin). All pets in the household should be treated.

2. Yeast Infections

Yeast overgrowth occurs when conditions inside the ear become overly moist and warm, often due to allergies or poor ventilation.

This condition is caused by allergies, humidity, poor grooming, compromised immune system, but can be prevented by keeping cats’ ears clean and dry, especially after bathing.

Symptoms:

• Foul-smelling discharge
• Yellow or brown wax
• Redness and itching

Treatment: Antifungal drops and identification of any underlying cause.

3. Bacterial Infections (Otitis Externa)

A bacterial infection of the outer ear canal can develop after trauma, mites, or moisture buildup. If untreated, it can spread deeper into the ear.

Bacterial infections are caused by trauma, untreated mites or yeast, and trapped moisture. It can be prevented by regular inspection and avoiding over-cleaning.

Symptoms:

• Swelling and pain
• Yellow or green pus-like discharge
• Fever or lethargy
• Odor from the ear

Treatment: Antibiotics (oral or topical), anti-inflammatories, and cleaning.

4. Aural Hematoma

This is a collection of blood within the ear flap, often resulting from violent head shaking or scratching. It causes swelling and discomfort.

Aural Hematoma is caused by trauma due to underlying ear irritation and can be prevented by addressing the root cause, like mites or infection, promptly.

Symptoms:

• Puffy, balloon-like ear flap
• Warm to the touch
• Painful when handled

Treatment: Surgical drainage or needle aspiration by a vet.

5. Polyps Or Growths

Benign or malignant growths can form in the ear canal, interfering with hearing and causing discharge.

They are caused by chronic inflammation and genetic predisposition, but can also result from unknown reasons.

Prevention usually takes the form of regular vet checks to catch abnormal growths early.

Symptoms:

• Persistent wax or pus
• Hearing loss
• Head tilt or disorientation

Treatment: Surgical removal and biopsy.

6. Foreign Bodies

Outdoor-loving Maine Coons may get grass seeds, dirt, or insects stuck in their ears from their exploration in wooded or grassy areas.

The best prevention method is to check your cat’s ears after outdoor time.

Symptoms:

• Sudden head shaking
• Tilting or pawing at the ear
• Localized irritation

Treatment: Vet removal and anti-inflammatory medication if needed.
