Ear mites are tiny parasites that can make your cat very uncomfortable. These tiny bugs live in your cat’s ears and cause itching, redness, and dark discharge. The good news is there are many effective treatments available. This guide will help you choose the best ear mite treatment for your cat.
What Are Ear Mites?
Ear mites (scientific name: Otodectes cynotis) are microscopic parasites that live in the ear canals of cats. They are about the size of a grain of salt and can barely be seen with the naked eye. These tiny bugs feed on ear wax and skin oils, causing irritation and inflammation.
Mites spread easily between cats through close contact. Kittens often get mites from their mother. Outdoor cats and cats living in shelters are more likely to get mites than indoor-only cats.
Signs Your Cat Has Ear Mites
How do you know if your cat has ear mites? Look for these common signs:
- Scratching ears a lot – Your cat may paw at their ears or rub their head against furniture
- Shaking head – This is a common way cats try to relieve ear discomfort
- Dark ear discharge – Mites cause a black or dark brown discharge that looks like coffee grounds
- Red, swollen ears – The ear canal may look inflamed and feel warm to the touch
- Bad smell – Infected ears often have a strong, unpleasant odor
- Ear pain – Your cat may pull away when you touch their ears
If you notice any of these signs, it’s important to start treatment right away. Untreated ear mites can lead to ear infections or even hearing loss.
Types of Ear Mite Treatments
There are two main types of ear mite treatments for cats:
1. Prescription Medications
These treatments require a visit to the veterinarian but are often more effective:
Revolution Plus This is a monthly topical treatment applied to the back of your cat’s neck. It kills ear mites, fleas, ticks, and prevents heartworms. Safe for cats 8 weeks and older. One dose usually takes care of ear mites, but your vet may recommend a second dose 4 weeks later.
Advantage Multi Another monthly topical treatment that kills ear mites along with fleas, heartworms, and intestinal worms. Contains imidacloprid and moxidectin as active ingredients. Approved for cats 9 weeks and older.
Milbemite Otic Solution This liquid medication is applied directly into the ears. It contains milbemycin oxime and is safe for kittens as young as 4 weeks old. Most cases require only one treatment, but severe infestations may need a second dose after 7 days.
2. Over-the-Counter Treatments
These products can be purchased without a prescription at pet stores or online:
Four Paws Healthy Promise Aloe Ear Mite Treatment Contains pyrethrins to kill mites and aloe vera to soothe irritated ears. For cats over 12 weeks old. Apply 4-5 drops in each ear daily for 7-10 days. Price is around $5-10 for a 0.75 oz bottle.

How to Apply Ear Mite Treatment
Applying ear mite treatment is easier than you might think:
- Gather supplies – You’ll need the medication, cotton balls, and possibly a helper for wiggly cats
- Prepare your cat – Find a comfortable position, possibly wrapping your cat in a towel if they resist
- Clean ears first (for most treatments) – Use a cat-safe ear cleaner and cotton ball to gently remove debris
- Apply medication – Hold the ear flap up, apply the recommended number of drops into the ear canal
- Massage – Gently massage the base of the ear for 30 seconds to help distribute the medication
- Let your cat shake – This helps move the medication deeper into the ear canal
- Clean excess – Use a cotton ball to wipe away any discharge that comes out
Pro tip: Never use cotton swabs (Q-tips) deep in your cat’s ear, as this can damage the ear canal or eardrum.
Safety Considerations
- Age restrictions: Most OTC treatments are not safe for kittens under 12 weeks old
- Weight requirements: Some treatments have minimum weight requirements
- Drug interactions: Tell your vet about any other medications your cat is taking
- Human safety: Wash hands thoroughly after applying treatments
- Storage: Keep all medications out of reach of children and pets
When to See the Veterinarian
While many ear mite infestations can be treated at home, you should consult a vet if:
- Your cat is a kitten under 4 weeks old
- The ears are severely swollen, bleeding, or have pus
- Your cat seems to be in extreme pain
- There’s no improvement after 2 weeks of treatment
- Your cat has recurring ear mite infestations
Preventing Future Ear Mite Infestations
The best way to deal with ear mites is to prevent them from occurring in the first place:
- Use monthly parasite preventatives like Revolution Plus or Advantage Multi
- Regularly check your cat’s ears for signs of mites or infection
- Keep outdoor cats away from stray animals
- If you have multiple pets, treat all of them if one gets mites
- Clean your cat’s bedding and toys regularly
- Schedule regular veterinary check-ups
