Cat Ear Mites vs. Yeast Infections: How to Spot the Difference (Vet-Approved)

Smelly, irritated ears might signal a health issue in your cat. Is it an infection or ear mites? While yeast and bacterial ear infections are more common in dogs, they can occur in cats, often due to an underlying issue. If your cat has an ear infection, ear mites might be the culprit since they can trigger infections.

However, this isn’t always the case, especially in older cats or those with allergies. Let’s explore the key differences between these conditions to help you provide the best care for your cat.

At A Glance

 

Overview of Ear Mites

 

Virtually all cats are susceptible to ear mites. They’re highly contagious, so if one cat in your home has them, it’s likely only a matter of time before others are affected. They can also spread between species, though the Otodectes cynotis mite rarely infects humans.

Ear mites are a common issue in cats but are not typically serious if treated promptly. However, if left unchecked, they can lead to secondary infections, such as yeast infections, which may eventually impact your cat’s hearing.

 

Signs of Ear Mites

Ear mites are relatively easy to identify. Since cats are meticulous groomers, a dirty-looking outer ear (pinna) often indicates an active infection. Common signs of ear mites include:

• Redness
• Head shaking
• Scratching
• Brown or black specks resembling coffee grounds
• Excessive dark brown or black earwax
  
  

How Are Ear Mites Diagnosed and Treated?

At the vet, a swab of debris from your cat’s ears will likely be examined under a microscope to confirm ear mites. If caught early, before an infection develops, your cat’s ears will be thoroughly cleaned, and you’ll be sent home with ear mite medication.

Your vet may schedule a follow-up appointment in a few weeks to ensure the mites are completely gone. Clearing an infestation can take 3 to 4 weeks due to the ear mites' life cycle.

How Common Are Ear Mites in Cats?

There’s a misconception that having a parasite infestation means you’re a bad pet owner or live in unclean conditions. This isn’t true. Many cats, especially those that go outside, will experience ear mites at some point in their lives. Don’t feel embarrassed about taking your cat to the vet for treatment. Veterinarians encounter ear mites regularly and are ready to provide the care your cat needs to feel better.

Overview of Yeast Infection

Yeast infections are uncommon in cats. When they do occur, they usually affect the pinna (outer ear) and ear canal rather than the middle or inner ear. However, if left untreated, the infection can spread deeper, potentially leading to hearing loss.

 

Signs of a Yeast Ear Infection

Yeast infections often have a distinct sour smell and may present with various symptoms, including:

• Redness
• Itchiness
• Frequent scratching or head shaking
• Ear discharge
• Excessive brown wax buildup

If the infection spreads to the middle ear, additional signs may include:

• Head tilting
• Hearing loss
• Facial drooping
• Abnormal eye movements
• Loss of balance or stumbling

 

How Are Yeast Infections Diagnosed and Treated?

Yeast infections in cats often stem from allergies or a weakened immune system. If an allergy is suspected, your vet may recommend medication, dietary changes, or lifestyle adjustments. Ear mites, a common cause of yeast infections, may require additional treatments.

To diagnose the infection, your vet will take a swab of ear debris for a cytology test to identify whether it’s caused by bacteria or a fungus like yeast. In severe cases, they may need to check if the infection has damaged the ear drum, which could require sedation. Most cats recover fully unless the case is very advanced.

If the ear drum is intact, treatment typically involves cleaning the ears and applying drops containing antifungal, antibacterial, and anti-inflammatory medications. You’ll likely be sent home with additional drops and instructions for keeping your cat’s ears clean.

  

Should I Take My Cat to the Vet for an Ear Problem?

Yes, you should take your cat to the vet to properly diagnose and treat any ear issue. A vet can perform a cytology test to identify the root cause and prescribe the right medication. With their guidance, you might be able to clean your cat’s ears at home using a cat-specific ear cleaner if ear mites are suspected. However, professional treatment is still necessary to eliminate the mites, their eggs, and any associated bacterial or yeast infections.

It’s always better to act quickly and consult your vet if you suspect an ear infection. Attempting to treat it at home isn’t recommended, as infections may spread to the middle or inner ear. Additionally, your cat will likely require prescription antibacterial or antifungal drops for effective treatment.

 

Regular Ear Cleaning is important!

Regular ear cleaning is essential for maintaining your cat’s ear health and preventing potential issues like infections or mite infestations. Cats are prone to wax buildup, dirt, and moisture in their ears, which can create a perfect environment for bacteria, yeast, or parasites to thrive. By incorporating gentle ear cleaning into your cat’s grooming routine, you can remove debris, reduce the risk of irritation, and spot early signs of problems before they escalate. Always use a vet-approved ear cleaner specifically designed for cats, and consult your veterinarian for guidance if you’re unsure about the process. A little care goes a long way in keeping your cat comfortable and healthy.
