# Cat Shaking Head and Scratching Ears: Causes and Urgency


## Key Takeaways

- Head shaking and ear scratching in cats are indicative of discomfort within the ear canal, most commonly caused by ear mites (Otodectes cynotis), bacterial or yeast infections (otitis), or foreign bodies like grass seeds.
- Emergency signs necessitating immediate veterinary attention include constant head tilting, circling, inability to stand, vomiting, swollen/painful ears, thick pus or blood discharge, sudden deafness, or seizures, which can signal severe inner ear infections or ruptured eardrums.
- Moderate urgency signs, such as near-constant head shaking, significant scratching leading to redness or hair loss, foul ear odor, visible dark brown/yellow discharge, flinching upon ear touch, or increased lethargy, warrant a same-day veterinary appointment for diagnosis and prescription treatment.
- Mild, occasional head shaking with no other symptoms can be monitored at home for 24-48 hours, but any increase in signs or the appearance of new symptoms requires prompt veterinary consultation, as ear problems rarely resolve spontaneously.
- Diagnostic procedures performed by a veterinarian typically involve otoscopic examination to visualize the ear canal and eardrum, microscopic examination of ear swabs for mites, bacteria, or yeast (cytology), and potentially imaging for chronic or severe cases.
- Owners should avoid inserting any objects into the ear canal, administering human medications, or using over-the-counter treatments without veterinary guidance, as these actions can worsen conditions or cause iatrogenic damage.

If your cat is shaking its head and scratching its ears, you are right to be concerned. This behavior is almost always a sign that something feels wrong inside the ear canal. The most common causes are ear mites, bacterial or yeast infections, and foreign objects like grass seeds. Most of these are treatable, but some can worsen quickly if ignored.

First, check for emergency signs. If your cat is tilting its head constantly, unable to stand, circling, vomiting, or has a swollen or painful ear, do not wait. These can indicate a severe inner ear infection, a ruptured eardrum, or a foreign body that has traveled deep into the ear. Take your cat to an emergency veterinarian immediately. For everything else, read on to understand what you are seeing and how urgent it really is.

## Is This an Emergency?

The table below sorts your cat's signs into three levels. Use it to decide your next step, but remember that a phone call to your regular veterinarian is always a good first move if you are unsure.

## What Is Most Likely Going On: Ear Infections

Ear infections are the most common reason a cat shakes its head and scratches its ears. The medical term is otitis, and it means inflammation or infection of the ear canal. You may see redness inside the ear flap, a brown or yellow discharge, or you may simply smell something unpleasant. The cat shakes because the infection itches or hurts.

Infections can be caused by bacteria or by yeast, which is a type of fungus that normally lives in small numbers on the skin. When the ear canal becomes moist, irritated, or blocked, these organizms multiply out of control. A cat with an ear infection often holds its head to one side or rubs its ear along the floor or furniture. These infections do not resolve on their own. They require a veterinarian to look inside the ear, identify the organizm under a microscope, and prescribe the correct medication. Dosing must come from the treating veterinarian because the wrong drug or the wrong amount can make the infection worse or damage the ear.

## Ear Mites: The Classic Cause in Cats

Ear mites are tiny parasites that live inside the ear canal. They are extremely common in kittens and in outdoor cats. The medical name is Otodectes cynotis. These mites cause intense itching, and you will often see a dark, crumbly discharge that looks like coffee grounds inside the ear. The cat may shake its head violently and scratch until the skin around the ear becomes raw.

Ear mites are highly contagious between cats, so if you have more than one cat, they may all need treatment. A veterinarian can confirm mites by taking a small sample of the ear discharge and looking at it under a microscope. Treatment usually involves prescription ear drops or a topical medication applied to the skin. Over-the-counter mite treatments are often ineffective and can delay proper care, so it is safer to have the diagnosis confirmed first.

## Foreign Bodies: Something Stuck in the Ear

A foreign body is any object that does not belong in the ear. Grass seeds, plant awns, small pieces of toy, or even a clump of dirt can find their way into a cat's ear canal. The cat shakes its head and scratches because the object is irritating the sensitive lining of the ear. This can happen suddenly, often after the cat has been outdoors in long grass or weeds.

A foreign body will not come out on its own. In fact, head shaking can push it deeper. If you can clearly see an object at the very opening of the ear, do not try to pull it out with tweezers. You risk pushing it further in or damaging the eardrum. A veterinarian has special tools and lighting to remove the object safely. If the object has been in for more than a day, there may also be a secondary infection that needs treatment.

## What Else Could It Be

Not every head shake is an ear problem. Allergies, either to food or to something in the environment, can cause itchy ears and skin. Polyps, which are benign growths in the ear canal, can cause shaking, discharge, and a head tilt. A skin condition called dermatitis can affect the ear flaps. In older cats, a tumor in the ear canal is possible, though less common. Finally, dental pain can sometimes cause a cat to shake its head or paw at its face, though this is less typical.

The key point is that you cannot tell these apart at home. The inside of a cat's ear canal is narrow and curved, and the eardrum sits deep inside. If the eardrum is ruptured, certain medications can cause deafness or severe dizziness. Only a veterinarian can safely examine the ear with an otoscope, which is a lighted instrument, and determine what is actually wrong. The American Veterinary Medical Association provides general guidance on recognizing when professional care is needed, and the MSD Veterinary Manual offers detailed descriptions of ear conditions in cats. Both are reliable resources for understanding what your veterinarian will look for.

If your cat has only mild, occasional shaking and no other signs, you can watch for 24 to 48 hours. Keep the ears dry and do not put anything inside them. If the shaking becomes more frequent, if you see discharge or odor, or if your cat seems painful, book an appointment that same day. Ear problems rarely fix themselves, and early treatment is easier, cheaper, and more comfortable for your cat.

## What You Can Do at Home Right Now

If your cat is shaking its head and scratching its ears, the first step is to look, not to treat. You can safely do a visual check, but you must not put anything inside the ear canal.

**Safe to do:**

- Look at the outside of the ear flap for redness, swelling, scabs, or discharge.
- Gently lift the ear flap and look at the opening of the canal. You may see dark crumbly debris, yellow pus, or a small object.
- Watch your cat for 10 minutes and count how many times it shakes its head or scratches. Note whether it favors one ear.
- Check the skin around the head, neck, and face for fleas, dandruff, or bald patches.

**Never do these things:**

- Do not insert cotton swabs, fingers, tweezers, or any tool into the ear canal. You can push debris or a foreign body deeper, damage the eardrum, or cause bleeding.
- Do not pour water, vinegar, alcohol, or over-the-counter ear cleaners into the ear. If the eardrum is ruptured, liquids can enter the middle ear and cause severe pain or balance problems.
- Do not give your cat any human pain medication. Many human drugs are toxic to cats. The American Veterinary Medical Association lists poisoning as a reason to seek immediate professional help, and dosing must always come from a veterinarian.
- Do not try to remove a visible object yourself. A grass seed or foxtail can be barbed and may break apart.

If your cat is in obvious pain, has a swollen or hot ear flap, tilts its head constantly, cannot stand, or is circling, stop the home check and go to an emergency clinic now. These signs can indicate a ruptured eardrum, a severe infection, or a foreign body that has migrated deeper.

## What to Write Down Before Calling the Vet

A few minutes of observation will help the veterinarian give you better advice, whether in person or online. Write down:

- How long the shaking and scratching has been going on. Hours, days, or weeks.
- How often it happens. For example, 5 head shakes per minute, or scratching every few minutes.
- Which ear seems affected, or if both ears are involved.
- What you see in the ear. Color and texture of any discharge, and whether it smells bad.
- Any other signs. Redness, swelling, head tilt, drooling, vomiting, reduced appetite, or lethargy.
- Whether your cat has been outdoors, near tall grass, or around other animals recently.
- Any medications, flea treatments, or ear products you have already used, and when.

Take a short video of the head shaking and scratching. Video is often more useful than a description because it shows the exact movement and frequency.

## A Home Ear Exam Guide

This exam is for observation only. It does not replace a veterinary examination, and it cannot tell you if the eardrum is intact.

1. Sit on the floor with your cat in your lap or beside you. Have treats ready.
2. Look at both ear flaps from the front and the back. Compare them. Note any swelling, redness, scabs, or hair loss.
3. Gently fold the ear flap back so the opening of the canal is visible. Do not push into the canal.
4. Look at the color of the skin inside the ear. Pale pink is normal. Bright red, dark red, or purple is not.
5. Look for discharge. Dark brown or black crumbly material often points to ear mites. Yellow, green, or pus-like discharge suggests a bacterial infection. A thick, waxy, dark discharge can appear with a yeast infection.
6. Smell the ear. A strong, sweet, or foul odor is abnormal and often indicates infection.
7. Watch your cat's reaction. If it pulls away, cries out, or tries to bite when you touch the ear, that ear is painful.
8. Check for a head tilt. Look at your cat from the front. If one ear sits lower than the other, or the head is tilted to one side, note it.

Stop the exam if your cat becomes stressed or aggressive. Pain in the ear can make even a friendly cat bite.

## Symptom Comparison Table

| Sign You See | Most Likely Causes | Urgency |
| --- | --- | --- |
| Dark brown or black crumbly debris, both ears, intense scratching | Ear mites | Moderate. Needs treatment, not an emergency. |
| Yellow or green pus, redness, strong odor, pain when touched | Bacterial ear infection | Moderate to high. Needs veterinary care within 24 hours. |
| Thick dark waxy discharge, mild odor, head shaking | Yeast infection | Moderate. Needs veterinary diagnosis. |
| Sudden violent head shaking, pawing at one ear, no visible discharge | Foreign body such as a grass seed | High. Needs same-day veterinary care. |
| Head tilt, circling, inability to stand, vomiting | Middle or inner ear infection, or a ruptured eardrum | Emergency. Go to a clinic now. |
| Swollen, hot, painful ear flap with no canal discharge | Ear hematoma, a blood blister from trauma or shaking | High. Needs same-day care to prevent permanent ear deformity. |

## What a Veterinary Visit Usually Involves

The veterinarian will start by asking about the history you wrote down. Then they will examine both ears with an otoscope, a tool with a light and a magnifying lens that lets them see deep into the canal and check the eardrum. This is the single most important step. Without it, the cause cannot be confirmed.

Common tests include:

- A swab of the ear discharge, examined under a microscope to identify mites, bacteria, or yeast.
- A cytology test, which stains the swab to show which type of infection is present.
- Imaging such as X-rays or CT scans, but only if the infection is severe, chronic, or suspected to have spread deeper.

Treatment depends on the cause. Ear mites require antiparasitic medication. Bacterial and yeast infections need medicated ear drops or oral medication. Foreign bodies are removed under sedation or anesthesia. A hematoma may need drainage and surgery.

Costs vary widely by region and clinic. A basic ear exam with a swab might fall in the range of $50 to $150. Adding cytology, sedation, or imaging can raise that to several hundred dollars. These are general ranges only, not quotes. Ask your clinic for an estimate before treatment begins.

## When an Online Vet Can Help, and When It Cannot

Some situations in this article require hands-on care and must not be handled remotely. A suspected foreign body, a painful swollen ear flap, a head tilt with balance problems, or any sign of a ruptured eardrum all need an in-person examination. A veterinarian cannot see inside the ear canal on a video call, and they cannot safely prescribe treatment without knowing the eardrum is intact.

A remote consultation is genuinely useful for early or mild presentations. If your cat has just started shaking its head, if the ear looks clean and pink, or if you are unsure whether a sign warrants a visit, an online vet can help you decide. They can also answer questions about medication side effects, follow up on a known chronic condition, or advise on whether a recheck is needed.

A remote vet can take a history, watch video of your cat, look at visible signs on the outside of the ear, and give advice. In many states they can prescribe medication. But they cannot palpate the ear canal, listen to the chest, take a temperature, run bloodwork, or image anything. Prescribing rules differ by state, and a veterinarian may require an in-person examination before prescribing. If the remote vet advises an in-person visit, take that advice seriously. The American Veterinary Medical Association emphasizes that recognizing when professional care is required is a core part of responsible pet ownership.

## Common Mistakes Owners Make With Ear Problems

**Mistake: Cleaning too deep.** Cotton swabs push wax and debris further into the ear canal. They can also damage the eardrum. If the eardrum is already torn, fluid can reach the middle ear and cause worse problems. What to do instead: clean only what you can see on the outer flap. Leave the canal itself to your veterinarian.

**Mistake: Stopping medication early.** Ear infections look better before they are cured. Stopping drops after two days because the shaking stopped often leads to a relapse within a week. Finish every dose exactly as prescribed, even if your cat seems normal.

**Mistake: Using leftover medication.** Old drops from another pet or a previous infection may be expired, the wrong drug, or the wrong strength. They can also contain steroids that hide signs while the infection worsens. Throw away unused ear medication after treatment ends.

**Mistake: Assuming it is ear mites.** Mites are common in kittens, but adult cats with recurring ear trouble more often have yeast or bacterial infections, polyps, or allergies. Treating for mites when the cause is bacterial delays proper care.

**Mistake: Waiting to see if it resolves.** Chronic inflammation thickens the ear canal over time. What starts as a simple infection can become resistant to treatment. If shaking and scratching persist beyond 24 to 48 hours, book a veterinary appointment.

| Common Mistake | Better Action |
| --- | --- |
| Using cotton swabs in the canal | Wipe only the visible ear flap with a soft cloth |
| Stopping drops when signs improve | Complete the full course prescribed |
| Reusing old ear medication | Discard leftovers and get a fresh diagnosis |
| Assuming mites in every cat | Let a vet identify the actual cause |
| Waiting weeks before calling | Seek care within 24 to 48 hours |

## How to Reduce the Chance of Recurrence

Check your cat's ears weekly. Look for redness, dark debris, odor, or swelling. A healthy ear is pale pink, clean, and odorless. Catching changes early makes treatment shorter and cheaper.

Dry ears thoroughly after bathing. Moisture trapped in the canal encourages yeast overgrowth. If your cat swims or gets wet, gently dry the outer ear with a soft towel.

Control fleas strictly. Fleas trigger allergic skin disease, and allergic cats are prone to ear inflammation. Use a veterinarian-approved flea preventive year-round, also in summer.

Manage underlying allergies. Many cats with repeated ear infections have food or environmental allergies. Your veterinarian may recommend a food trial or allergy medication. Treating the skin condition often reduces ear flare-ups.

Keep foreign material away. Grass awns, foxtails, and plant seeds can lodge in the ear canal during outdoor time. After walks or play in tall grass, inspect your cat's ears and brush out burrs from the fur around the head.

Follow the American Veterinary Medical Association guidance on routine wellness visits. Annual examinations let your vet spot early ear changes before they become painful infections. Cats hide discomfort well, so a professional look matters even when your cat seems fine.

## What Recovery and Ongoing Management Look Like

Most uncomplicated ear infections improve within 5 to 7 days of starting treatment. Full resolution of inflammation can take 2 to 3 weeks. Ear mite treatment typically requires a second dose 3 to 4 weeks later to break the life cycle.

Your cat may need a recheck examination after treatment. This is not optional. The vet re-inspects the eardrum and confirms the infection is gone. Some infections look cured but still harbor bacteria.

Chronic cases require longer management. Cats with allergies, polyps, or narrow ear canals may need periodic cleaning under sedation, long-term medication, or in severe cases, surgery. Your veterinarian will explain the specific plan for your cat.

During recovery, keep the ears dry and prevent scratching. An Elizabethan collar may be necessary for a few days so the ear canal can heal without trauma. Some cats tolerate the collar poorly, but it prevents self-injury that prolongs healing.

Watch for warning signs during treatment. If shaking worsens, the head tilts, or your cat becomes lethargic, contact your veterinarian immediately. These can indicate the infection is spreading or the eardrum has ruptured. The MSD Veterinary Manual notes that deep ear infections can affect balance and hearing if left untreated.

## Frequently Asked Questions

**Can I use olive oil or vinegar in my cat's ears?**
No. Home remedies like vinegar, alcohol, or oils can sting inflamed tissue and disrupt the ear's natural balance. If the eardrum is torn, liquids can enter the middle ear and cause severe pain or balance problems. Stick to products your veterinarian provides. If you suspect a foreign body, do not put anything in the ear, as you may push the object deeper.

**How do I know if the eardrum is ruptured?**
You cannot tell at home. Signs of a ruptured eardrum include a head tilt, circling, loss of balance, or discharge that looks like coffee grounds. Only a veterinarian can confirm this with an otoscope. Never clean deep into the ear if you suspect a rupture, as this can cause permanent damage.

**My cat shakes her head only after eating. Is that an emergency?**
Head shaking after eating is often related to pain or irritation in the mouth or throat, not the ears. Check for food stuck between teeth, dental disease, or a sore in the mouth. If the shaking happens every meal or is accompanied by drooling, pawing at the mouth, or reduced appetite, schedule a veterinary visit within a day or two.

**Will ear problems go away on their own?**
Rarely. Mild wax buildup may resolve, but infections, mites, and foreign bodies do not self-cure. Untreated ear disease worsens over time and can lead to chronic pain, hearing loss, or a hematoma, a blood blister on the ear flap from violent shaking. Seek professional diagnosis instead of waiting.

**How much does an ear infection visit cost?**
Costs vary widely by region and clinic. A basic examination with ear cytology typically ranges from 80 to 200 dollars. Medications add 30 to 100 dollars. Advanced testing like cultures or imaging costs more. Ask your clinic for an estimate before treatment begins. Pet insurance may cover part of the cost if you have a policy.

**Can I prevent ear mites with regular cleaning?**
Cleaning helps remove debris but does not prevent mite infestation. Mites spread through direct contact with infected animals. Keeping your cat indoors, using flea preventives, and isolating new pets for a quarantine period reduce exposure. If one pet has mites, treat all pets in the household, as mites are highly contagious.
