How to Clean a Cat’s Ears (and When Not To)

Most cats keep their own ears clean, so cleaning a cat’s ears is less about a routine and more about knowing what a healthy ear looks like, when a gentle wipe is fine, and when the ear needs a vet instead. This page covers all three, plus how to handle a cat that will not sit still.
The short answer: check your cat’s ears about once a week, but do not clean them unless they look dirty. If an ear is dirty but not red, sore or smelly, wipe the ear flap and the part of the canal you can see with a cotton ball and a cat-safe ear cleaner. Never use cotton swabs, hydrogen peroxide or alcohol. Redness, odor, discharge, dark debris, scratching, head shaking or a head tilt mean a vet visit, not cleaning at home.
How we wrote this: the advice comes from veterinarians writing for PetMD and VCA Animal Hospitals, Cornell University’s Feline Health Center, International Cat Care and the ASPCA, all linked where they are used and checked on 29 October 2026. It is general care information, not veterinary advice, and we do not give any treatment advice. If you think your cat has an ear problem, see a vet.
Do cats need their ears cleaned?
Usually not. VCA Animal Hospitals puts it plainly: “Ear cleaning is not usually necessary in cats“, and it warns that over-cleaning may cause irritation in the ear canal. PetMD says most cats do not need frequent ear cleaning, but their ears should be checked regularly, and that indoor cats can still get dirty ears. International Cat Care goes further: it says most vets will advise you to avoid tampering with a cat’s ears at all, because the tissue lining the ear canal is very delicate and easily damaged.
Some cats need more help. International Cat Care says hairless breeds and cats with curled ears may need more care, and to ask your vet team how to do it safely.
What a healthy cat ear looks like
The ASPCA suggests checking your cat’s ears once a week. It describes healthy inner ears as pale pink, with no debris or odor and little or no earwax. Cornell suggests routinely looking for swelling, discharge, discoloration and a build up of dirt and debris. A weekly look during petting or brushing is enough; our cat brush guide has tips for keeping grooming calm.
When to see a vet instead of cleaning
PetMD says not to clean your cat’s ears at home if an infection or injury is suspected. See a vet if you notice any of these, which come from the ASPCA, International Cat Care and PetMD:
- Persistent scratching or pawing at the ears, or shaking the head
- Holding the head to one side, loss of balance, or walking in circles
- Redness, swelling, pain or sensitivity to touch
- An unpleasant smell
- Black, brown or yellowish discharge, or dark debris that looks like coffee grounds
- Debris that comes back after you clean it, bleeding, or hearing loss
Ear mites are a common cause of these signs. VCA says ear mites are the most common cause of ear infections in cats and that your vet must diagnose an ear infection. Cornell says ear mites are extremely contagious and that if you suspect them you should seek veterinary care without delay; left untreated, an ear infection can spread deeper and permanently affect hearing and balance. Cornell also says that if your cat keeps scratching at its ears, do not probe into them to find the cause; consult your vet as soon as possible. Dark debris can also be normal wax, PetMD notes, which is one more reason to let a vet look.
How to clean a cat’s ears
Only for an ear that looks dirty but is not red, sore or smelly. These steps follow PetMD‘s vet written guide, with the gentler outer ear method from the ASPCA.
- Get a cat-safe ear cleaner. PetMD says not to put anything other than a cat-approved ear cleaner in your cat’s ears, and names over the counter cleaners such as Epi-Otic as generally safe for cats, but says it is best to ask your vet first. The ASPCA also suggests asking your vet for a recommendation.
- Have cotton balls or gauze and treats ready. No cotton swabs: PetMD says they can push debris deeper and damage the eardrum.
- Hold your cat calmly. PetMD suggests gently wrapping your cat in a towel to keep them still.
- Apply the cleaner. PetMD says to squeeze it from a soaked cotton ball or put a small amount into the ear canal, then gently massage the base of the ear for a few seconds. The ASPCA’s gentler method skips the canal: put a little cleaner on a cotton ball, fold the ear back gently and wipe away only the wax and debris you can see.
- Let your cat shake their head.
- Wipe the ear flap and the visible part of the canal with a cotton ball or gauze wrapped around your finger. Lift the dirt out rather than rubbing it in, and never go deeper than you can see.
- Reward your cat with a treat or play.
Our view, not a quote from the sources: if one ear is clean, leave it alone. Clean only what needs it.
What not to use
- Cotton swabs: VCA warns of the risk of puncturing the ear drum, and PetMD says they push debris deeper.
- Hydrogen peroxide: PetMD says it should never be used in a cat’s ears.
- Alcohol: VCA says peroxide or alcohol can cause irritation.
- Home remedies or leftover medicine: treating an infection or mites is your vet’s job after an exam.
If your cat will not let you
International Cat Care says to build up your cat’s tolerance of handling gradually and that a cat should never be groomed by force without the option to escape. The ASPCA says that if your cat fights grooming and you or your cat could get hurt, book a professional groomer or your vet. Our view: start by simply touching and folding back the ear for a second with a treat, over several days, before you ever bring out a cotton ball.

FAQ
How often should I clean my cat’s ears?
Most cats never need routine ear cleaning. Check the ears about once a week and clean only when they look dirty but healthy. If dirt keeps coming back, see a vet.
What is the black stuff in my cat’s ears?
It may be normal wax, but PetMD says it can also be a sign of ear mites or a yeast infection, and the ASPCA describes mite debris as looking like coffee grounds. Let your vet check it.
Can I use water to clean my cat’s ears?
PetMD says not to put anything other than a specifically cat-approved ear cleaner in your cat’s ears. Ask your vet what to use.
Can I use cotton swabs (Q-tips) on my cat’s ears?
No. VCA warns that swabs risk puncturing the ear drum, and PetMD says they push debris deeper.
Can I treat ear mites at home?
Cornell says to seek veterinary care without delay if you suspect ear mites, and VCA says your vet must diagnose an ear infection. Your vet will also tell you whether other pets need checking, since mites spread easily between pets.
