Ear Mites in Cats: Causes, Symptoms, & Treatment


Ear mites are tiny parasites that commonly affect cats, particularly those that spend time outdoors or in close contact with other animals. Here’s an overview of ear mites in cats, including their causes, symptoms, and treatment:


  1. Parasitic Infestation: Ear mites, scientifically known as Otodectes cynotis, are highly contagious parasites that can easily spread from one cat to another through direct contact.
  2. Outdoor Exposure: Cats that spend time outdoors or in environments where other animals frequent are at higher risk of contracting ear mites.
  3. Transmission from Mother: Kittens can acquire ear mites from their mother during nursing.


  1. Head Shaking: Cats with ear mites often shake their heads or tilt them to one side due to discomfort and irritation.
  2. Scratching: Excessive scratching at the ears or rubbing the ears against furniture or the floor is common.
  3. Ear Discharge: Dark, waxy discharge resembling coffee grounds may accumulate in the ear canal.
  4. Ear Odor: A foul odor may be present in the ears due to the accumulation of discharge and debris.
  5. Redness and Inflammation: The ear canals may appear red, inflamed, or irritated.
  6. Hair Loss: In severe cases, hair loss around the ears may occur due to scratching.


  1. Veterinary Examination: A veterinarian can diagnose ear mites through a physical examination and microscopic evaluation of ear discharge.
  2. Medicated Ear Drops: Prescription ear drops or ointments containing acaricides or insecticides are commonly used to kill ear mites and alleviate symptoms. These medications may need to be administered once or twice daily for several weeks.
  3. Ear Cleaning: Cleaning the ears to remove excess wax, discharge, and debris can help improve the effectiveness of treatment. Use a veterinarian-approved ear cleaning solution and follow the instructions carefully.
  4. Environmental Control: Thoroughly clean and disinfect your cat’s bedding, toys, and living areas to prevent re-infestation.
  5. Treatment for Other Pets: Treat all pets in the household for ear mites, even if they do not show symptoms, to prevent the spread of infestation.
  6. Follow-Up Care: Follow your veterinarian’s recommendations for follow-up examinations and treatments to ensure that the infestation has been fully resolved.


  1. Regular Veterinary Check-ups: Schedule routine veterinary examinations to monitor your cat’s ear health and address any potential issues promptly.
  2. Parasite Control: Use veterinarian-recommended flea and tick preventatives to help protect your cat from ear mites and other parasites.
  3. Minimize Outdoor Exposure: Limit your cat’s outdoor activities, especially if they are prone to ear mite infestations.
  4. Maintain Cleanliness: Keep your cat’s living areas clean and free of excess debris to minimize the risk of ear mite infestation.

By understanding the causes, symptoms, and treatment options for ear mites in cats, you can take proactive steps to protect your pet’s ear health and well-being. If you suspect that your cat has ear mites or if you have any concerns about their ear health, consult with your veterinarian for proper diagnosis and treatment.
