What Are Ear Mites?
Ear mites are microscopic parasites belonging to the species Otodectes cynotis. They live in the cat's ear canal and feed on ear wax, oils, and skin debris. Despite their small size, they can cause significant irritation and are highly contagious among animals, especially cats, dogs, and ferrets.
While ear mites are not typically dangerous to humans , they are a serious concern for pets and should be treated promptly.
How Do Cats Get Ear Mites?
Ear mites spread through direct contact with an infected animal. Cats contract ear mites primarily through direct contact with infested animals. Cats that go outdoors, live in multi-pet households, or are exposed to stray or shelter animals are more at risk. Ear mites are highly contagious and spread quickly among housemates, including other cats and dogs.
Here are common ways cats get ear mites:
Contact with infected cats or dogs
Sharing bedding, grooming tools, or litter boxes
Being in crowded environments like shelters or kennels
Exposure to contaminated grooming tools and tables

Why It’s Important to Check for Ear Mites
Untreated ear mites can lead to secondary bacterial or fungal infections, scarring, and long-term damage to a cat’s ears. In severe cases, they may even affect a cat’s hearing. Ear mites have a three-week lifecycle going from egg to reproducing adult, making early treatment crucial.
Early detection is crucial to:
Prevent discomfort and pain
Stop the spread to other pets
Avoid costly veterinary treatments for complications by ensuring a proper diagnosis from a veterinarian
Common Signs of Ear Mites in Cats
Knowing what to look for is the first step in checking your cat for ear mites. Cats with ear mites may scratch their ears excessively. Here are the most common symptoms:
1. Frequent Scratching
Cats with ear mites often scratch at their ears or shake their heads excessively in an attempt to relieve the itching. Hair loss, sores, and inflamed ears can occur from excessive scratching due to ear mites.
2. Dark, Crusty Ear Discharge
One of the hallmark signs of ear mites is a dark brown or black discharge resembling coffee grounds. This is a mix of ear wax, blood, and mite debris.
3. Redness or Inflammation
The inside of the ear may appear red, swollen, and irritated due to constant scratching and mite activity. It is essential to determine the underlying cause to prevent further complications.
4. Hair Loss Around the Ears
Excessive scratching can lead to bald patches in the cat's fur near the ears and face.
5. Unpleasant Odor
While ear mites themselves don’t have a strong smell, secondary infections caused by scratching may result in a foul odor. These infections can be indicative of various ear conditions, so it is important to consult a veterinarian if you notice any abnormal earwax buildup or discharge.
How to Check for Ear Mites at Home
Although a veterinarian should ultimately diagnose and treat ear mites, you can perform a basic check at home to identify symptoms in your cat's ears. Here’s how:
Step 1: Prepare a Safe Environment
Choose a quiet room with good lighting.
Wrap your cat in a towel or blanket to prevent sudden movements.
Have a partner help hold your cat, if needed.
Step 2: Gently Examine the Ears
Lift the ear flap and look inside the external ear canal.
Use a flashlight or your phone’s light to get a better view.
Look for dark, waxy debris or signs of inflammation.
Step 3: Observe Your Cat’s Behavior
Note any signs of irritation when you touch the ears.
Monitor for excessive scratching or head shaking over time.
Step 4: Use a Magnifying Glass (Optional)
A small magnifying glass can help you see more details, but you won't be able to see the mites themselves without a microscope.
Confirming the Diagnosis: Visiting the Vet
While home inspection can be helpful, a veterinary exam is essential for confirming ear mites. The vet will use an otoscope to view inside the ear canal and collect a sample of ear debris for microscopic examination.

Rule out other ear problems like bacterial infections, yeast infections, or allergies
Veterinarians can distinguish between different types of infections and prescribe the correct treatment. An accurate diagnosis is crucial to ensure the proper treatment plan is followed.
Treatment Options for Ear Mites in Cats
Treating ear mites, once diagnosed, is typically straightforward but must be consistent and thorough to prevent reinfection. Successful treatment of ear mites often requires multiple treatments to eliminate all mite eggs and adults.
1. Topical Medications
Prescription ear drops containing anti-parasitic medication like ivermectin or selamectin
Applied directly into the ear canal daily for 7–10 days
2. Systemic Medications
Systemic and topical treatments like oral or injectable medications such as ivermectin or milbemycin
Effective in treating scabies throughout the body
3. Cleaning the Ears
Vets often clean the ears and the skin surface around them before treatment to remove debris and make the medication more effective.
Use only vet-recommended ear cleaners ; never use hydrogen peroxide or alcohol.
4. Treat All Pets in the Household
Because ear mites are highly contagious, all household pets, including cats and dogs, in the home should be treated, even if they don’t show symptoms. Indoor cats can get ear mites, especially if they have been in close contact with an infested animal.
Natural Remedies: Do They Work?
Some pet owners explore at home treatments such as olive oil, mineral oil, or apple cider vinegar. While these may suffocate mites temporarily , they do not kill the eggs and are not as reliable as prescription treatments like itch relief sprays.
Always consult your vet before using any home remedy.
How Long Does It Take to Get Rid of Ear Mites?
With proper treatment, ear mites can be eradicated within 7–30 days , depending on the medication used and how severe the infestation is.
Follow-up vet visits may be necessary to confirm that all mites are gone, as treatments must continue until the eggs hatch to prevent reinfestation.
Preventing Future Infestations
Prevention is the best approach to protect your cat from future ear mite issues. Here are some strategies: Veterinarians may recommend parasite prevention products as a proactive measure to manage various pests, including ear mites, fleas, and worms.
1. Regular Ear Checks
Inspect your cat's ear weekly for signs of mites or debris, especially if they spend time outdoors.
2. Routine Vet Visits
Annual or bi-annual check-ups help pet parents catch problems early.
3. Clean Bedding and Living Areas
Wash your cat’s bedding, toys, and litter area regularly to eliminate lingering mites and prevent the spread to other household pets. Cleaning your pet’s bedding regularly can reduce the risk of ear mite infestations.
4. Use Preventive Medications
Some flea and tick preventives also protect against ear mites. Talk to your vet about options. An important way to prevent ear mites in cats is to apply topical flea, tick, and heartworm preventatives each month year-round. Your vet may also prescribe medication to ensure comprehensive protection and treatment.
5. Limit Exposure to Stray or Unknown Animals
Avoid letting your cat interact closely with animals that haven’t been screened for parasites.

Indoor cats can still get ear mites through indirect contact or if they’re exposed to an infected animal. Regular grooming appointments help minimize the risk of ear mites in our feline friends.
❌ “You can’t see any signs of ear mites.”

❌ “Once treated, mites are gone forever.”
Ear mite infestation can recur without proper cleaning and preventive measures.
