If your cat has been shaking her head, pawing at one ear, or leaving behind a dark, coffee-ground-looking discharge, an ear infection may be the reason. Ear infections are less common in cats than in dogs.
In cats, an ear infection often points to something else going on beneath the surface, so getting to the cause matters just as much as easing the symptoms. Here's what a cat ear infection involves, how it's treated, and when it's time to bring your cat into your local veterinary practice.
What a Cat Ear Infection Actually Is
A cat's ear has three parts: the outer ear, the middle ear, and the inner ear. Most infections start in the outer ear canal, the part closest to the opening. When caught early, these are usually straightforward to treat. Left alone, though, an outer ear infection can work its way deeper into the middle or inner ear, where it becomes harder to clear and more uncomfortable for your cat. That's the main reason vets encourage treating ear issues sooner rather than later.
Signs Your Cat May Have an Ear Infection
Cats are good at hiding discomfort, so the signs can be subtle at first. Some of the more common ones include:
- Head shaking or tilting to one side
- Scratching or pawing at the ear
- Dark, waxy, or coffee-ground-colored discharge
- An odor from the ear
- Redness or swelling inside the ear flap
- Trouble with balance or unusual clumsiness
Balance changes, a persistent head tilt, or signs your cat feels off-kilter can suggest the infection has reached the inner ear. If you notice those, have your cat seen promptly.
What Causes Ear Infections in Cats
Because ear infections aren't especially common in cats, they usually develop due to an underlying issue rather than on their own. The most frequent culprit is ear mites, tiny parasites that are especially common in kittens and outdoor cats and spread easily between pets. Other causes include:
- Allergies, whether food-related or environmental
- Polyps or other growths in the ear canal
- Foreign material, such as a bit of grass or debris
- Excess wax buildup
- Conditions that affect the immune system
Identifying which of these is behind the infection helps treat it well, since clearing the infection without addressing the cause means it may come right back.
How a Cat Ear Infection Is Treated
Treating a cat ear infection starts with pinpointing the cause. Your veterinarian will examine the ear canal with an otoscope and usually take a small sample of the discharge to look at under a microscope. This shows whether mites, yeast, or bacteria are involved, which determines the right approach.
From there, treatment is matched to the cause. It may include a thorough ear cleaning, along with medication such as:
- Antiparasitics for ear mites
- Antibiotics for bacterial infections
- Antifungals for yeast
- Anti-inflammatories to ease swelling and discomfort
Most infections respond well to ear drops or ointments. For more stubborn, chronic, or deeper infections, your vet may add oral medication. Your veterinary team will also walk you through how to give any medication correctly and may schedule a follow-up to make sure the infection has fully cleared.
Home Care Your Vet May Recommend
Some care does happen at home, but it should always follow your vet's guidance. That usually means applying prescribed ear drops, keeping the ear clean with a product your vet recommends, and finishing the full course of medication even if your cat seems better partway through.
It's best to avoid home remedies you might come across online. A cat's ear canal is sensitive, and the wrong product, or cleaning an ear that has a ruptured eardrum, can make things worse. When you're not sure what's causing the problem, let your vet confirm the cause before putting anything in your cat's ear.
When to See a Vet
Most cat ear infections are treatable, especially when caught early. Getting your cat seen at the first signs of trouble helps prevent an infection from becoming chronic or spreading deeper, which in more serious cases can affect the facial nerves or hearing. If your cat is showing signs of an ear infection, a same-day exam is the fastest way to get answers and relief.

Preventing Future Ear Infections
A few simple habits go a long way toward keeping your cat's ears healthy:
- Check your cat's ears regularly for redness, odor, or discharge
- Stay on top of any underlying allergies with your vet's help
- Keep up with routine wellness visits, where small issues can be caught early
Frequently Asked Questions
How long does a cat ear infection take to heal?
Many outer ear infections improve within a week or two of starting treatment, while chronic or deeper infections can take longer. Following your vet's full treatment plan gives the best chance of clearing it completely.
Can a cat's ear infection clear up on its own?
It's unlikely. Because cat ear infections usually stem from an issue like mites or allergies, they tend to persist or worsen without treatment. A vet visit is the most reliable way to resolve it.
Are cat ear infections contagious to other pets?
The infection itself usually isn't, but ear mites, a common cause, spread easily between cats and other pets. If mites are involved, your vet may recommend treating your other animals too.
Can I use dog ear drops on my cat?
No. Never use another pet's medication or leftover drops. Cats can react differently to certain ingredients, and using the wrong product can cause harm. Always use what your vet prescribes specifically for your cat.
