Ear Mites in Cats

If your cat has been shaking their head, scratching around their ears, or showing signs of discomfort, they may be dealing with ear mites. Ear mites in cats are highly contagious parasites that live inside the ear canal, causing itchiness, inflammation, and discharge. Although small, these mites can lead to more serious problems if not treated by a veterinarian. Knowing what signs to look for—and acting quickly—can make a big difference in your cat’s comfort and health. In this blog, we’ll explain how ear mites in cats are transmitted, what symptoms to watch for, and how veterinary care can resolve the issue.

 

 

What Are Ear Mites in Cats?

Ear mites in cats are microscopic parasites that live and breed in the ear canal. The most common species affecting cats is Otodectes cynotis. These parasites feed on skin debris, wax, and oils, causing intense irritation and inflammation. Though they’re difficult to see without magnification, their presence is often obvious due to the discomfort they cause.

Ear mites in cats can lead to secondary infections if left untreated. As the infestation grows, the ear canal becomes increasingly inflamed, which can create a favorable environment for bacteria and yeast. In some cases, the damage may even affect hearing or balance. This is one of the reasons why early intervention is so important. Young cats and kittens are especially vulnerable to ear mites. However, cats of all ages—whether indoor or outdoor—can become infected if exposed to a host carrying mites.

How Do Cats Get Ear Mites?

Cats get ear mites through contact with another infected animal. This may happen during grooming, play, or shared living spaces. Ear mites in cats spread easily in environments with multiple pets, such as shelters, boarding facilities, and multi-cat households.

• Direct contact: Cats often contract mites from grooming or interacting with infected cats, dogs, or other animals.
• Shared items: Mites can survive for a short time on bedding, brushes, or furniture, allowing indirect transmission.
• Outdoor exposure: Cats that spend time outside are more likely to encounter wildlife or strays carrying mites.

Because these parasites are so contagious, even indoor cats are at risk. A new pet in the home or a recent visit to a pet care facility can expose your cat to ear mites.

Symptoms of Ear Mites in Cats

The symptoms of ear mites in cats are usually easy to spot—especially if your cat suddenly starts scratching or shaking their head more than usual. Early signs can be subtle, but they quickly progress if the infestation isn’t addressed. Signs to watch for include:

• Intense scratching around the ears and head
• Frequent head shaking
• Red or inflamed ears
• Dry, dark discharge resembling coffee grounds
• Strong or unpleasant odor from the ears
• Hair loss or scabs near the ears

Cats with ear mites may also appear irritable or sensitive to touch. Severe cases can lead to head tilting or balance issues due to inflammation in the inner ear. Because these symptoms can resemble other ear problems, such as infections or allergies, a veterinary diagnosis is essential.

How Veterinarians Diagnose Ear Mites in Cats

When diagnosing ear mites in cats, your veterinarian will begin with a physical exam and ear inspection. While signs of ear mites can be visible, further testing confirms the diagnosis.

• Visual inspection: Your vet will examine your cat’s ears for debris, redness, and inflammation.
• Microscopic evaluation: A sample of the ear discharge may be examined under a microscope to detect mites.
• Otoscope use: Your veterinarian may use a specialized tool to see deep into the ear canal.

Accurate diagnosis is key. Treating ear mites without confirmation may not resolve the issue and could delay proper care. Your vet will determine whether ear mites are present and rule out other conditions with similar symptoms.

Veterinary Treatment for Ear Mites in Cats

Your veterinarian will recommend a treatment plan based on your cat’s condition and the severity of the infestation. Professional care is the only safe and effective way to eliminate ear mites in cats.

• Topical medications: These are applied in or around the ears to target mites directly.
• Systemic treatments: Some anti-parasitic medications are given orally or applied to the skin.
• Ear cleaning: Your veterinarian may clean your cat’s ears to remove debris and improve treatment effectiveness.

Follow your veterinarian’s instructions carefully, and complete the full course of treatment—even if symptoms improve early. Incomplete treatment may allow mites to return. Never attempt to treat ear mites in cats using over-the-counter remedies or home treatments. These may be ineffective or cause further irritation. Veterinary care is the safest route.

Why Early Treatment Matters

Ear mites in cats do not resolve on their own. Without prompt treatment, the infestation can become more severe, leading to long-term irritation and possible complications. The longer the mites remain in the ear, the higher the risk of secondary infection such as:

• Bacterial infections: Mites damage the ear lining, creating an entry point for bacteria.
• Chronic inflammation: Persistent irritation can cause thickening of the ear canal over time.
• Hearing damage: In severe cases, mites may affect deeper structures within the ear.

What You Can Do to Prevent Ear Mites in Cats

While you can’t eliminate all risk, there are several steps you can take to reduce the chances of ear mites in cats:

• Monitor your cat’s ears for changes in color, odor, or discharge.
• Use a veterinary-recommended parasite prevention product regularly.
• Be cautious with new pets or contact with animals of unknown health status.
• Regularly wash bedding, grooming tools, and soft surfaces in multi-pet homes.

If one pet in the home is diagnosed with ear mites, your vet may recommend evaluating or treating other pets as well. This helps prevent re-infestation and keeps the whole household healthy.
