If your kitty has a bell on their collar, you’re probably all too aware of when they are shaking their head! After all, it sometimes seems like they only start noisily shaking their head and scratching their ears when your favorite TV show is on! But why do cats shake their heads? What are the possible causes, and when should you take them to see the veterinarian?

Read on below to find out more.

Why Do Cats Shake Their Head?

The truth is there are loads of reasons why your cat might be shaking their head.

But here are some of the possible causes:
  • Ear mites: Your feline friend might have some creepy crawlies in their ears! Ear mites can cause intense itchiness, and you might notice your cat scratching their ears as well as shaking their head. If you look closely, you might see a brown, thick, waxy discharge in the ears, and they might be going a bit bald on the backs of their ears from all the scratching.
    Ear mites are most common in young kittens but can affect cats of any age. If your veterinarian thinks that your cat might have ear mites, they might look at a swabbed sample under a microscope to see if they can see them crawling around!
  • Ear infection: Ear infections aren’t as common in cats as they are in dogs, but if your cat is shaking their head, it could be precisely that. Ear infections can be caused by bacteria or yeasts. As well as being itchy and painful, they can also spread deeper into the ear canal, causing more serious symptoms like trouble balancing. If your cat has an ear infection, you might notice that their ear is smelly or that they have a yellow, brown, or waxy discharge in their ear.
  • Aural hematoma: An aural hematoma occurs when small blood vessels burst within the ear cartilage, causing it to swell as it fills up with blood. If your cat has an aural hematoma, their ear pinna will look enlarged, like a balloon, and if you gently press it, you will feel that it is full of fluid. Aural hematomas can happen due to trauma, but they most often occur due to excessive scratching or head shaking. Once the hematoma forms, the ear canal becomes narrower, and any infection becomes trapped. The bacteria will begin to thrive in the moist, under-ventilated environment, and your poor kitty’s pain, itchiness, and discomfort will worsen.
  • Polyps: Sometimes, cats can develop polyps deep inside their ear or at the back of their throat. These are soft tissue growths that are usually benign rather than cancerous, and they can cause infection or inflammation. Depending on their location, they might interfere with your cat’s balance, breathing, eye movement, or pupil size.
  • Foreign material: Although it’s unusual, your cat might shake their head if they have a foreign object in it. Hairs, tiny seeds, or other vegetation could lodge in the ear canal and cause itchiness and irritation.
  • Fleas: You might think it odd that fleas could cause your cat to shake their head, but it’s true! Fleas and their bites can cause sudden itchiness and irritation that can make your kitty shake their head or excessively groom, as well as scratching.

What Other Symptoms Might Your Cat Show When They Shake Their Head?

If your cat is suffering from an ear infection, ear mites, or other itchy ailments, you might see them scratching at their ears with their hind legs. If your cat is quite private, they might not scratch in front of you, but you might spot the evidence if the backs of their ears start to look a bit bald!

An infection of the middle or inner ear or a polyp deep in their ear canal might cause them to tilt their head to one side, and they might lose their balance easily or act a bit drunk and wobbly. You might also notice that their pupils are different sizes or that their eyes are flickering side to side. If your cat’s balance is severely affected, they might start vomiting, a bit like when people get motion sickness or vertigo.

If your cat has fleas, they’ll probably give you some other clues aside from the itchiness! You might notice patches of thin fur or bald patches, and if you look closely, you might spot some fleas or flea dirt.

When to See a Vet

Most causes of head shaking in cats won’t get better on their own without veterinary treatment. However, if you suspect that your cat companion has some extra “friends” in the form of fleas, you might be able to treat them at home. It’s worth using a fine-tooth comb to check for fleas or flea dirt and ensure your cat is up-to-date with preventative treatments.

If your cat is shaking their head and has no other symptoms, and their ears look clean and comfortable, it’s okay to keep an eye on them for a couple of days to see if things improve. But, if they seem unwell, have other symptoms, or their ears are red, dirty, smelly, or sore, you should take them to see the veterinarian.

What Are the Possible Treatment Options?

If your cat is shaking their head, the treatment that your veterinarian recommends will depend on the cause.

Ear mites

If your veterinarian sees ear mites down the microscope after taking a sample from your cat, they’ll need to prescribe some treatment. There are various treatments for ear mites, including prescription ear drops and spot-on treatments. When using the ear drops, your veterinarian might suggest treating the ears for a week, then stopping for a week to allow any eggs to hatch. Once the eggs have hatched, the mites can be treated for a further week.

Ear infection

If your cat has an ear infection, they will need antibiotic treatment, usually given as drops into the ear. The type of antibiotic used will depend on which bacteria are causing the infection. Your veterinarian might take a swab to look at under their microscope, or they might send a sample to a specialist laboratory.

Aural hematoma

Aural hematomas often need to be drained. Your veterinarian may be able to use a needle or a small blade to release the blood from inside the ear while your cat is under sedation. However, sometimes the ear can refill with blood after drainage, so a semi-permanent drain or a surgical procedure might be needed. Unusually, some veterinarians have recently started using leeches to treat aural hematomas!


It’s not as easy as you think to find a polyp in your cat’s ear! They can be very deep inside the ear canal, behind the eardrum. So, your veterinarian might need to take X-rays or even do a CT scan to find it. Once located, polyps can be removed using various surgical techniques.

Foreign material

If your cat has a grass seed or other foreign material in their ear, your veterinarian might be able to see it using a special ear scope. If they find foreign material, they can usually remove it under sedation.


Fleas can be treated with spot-on treatments, sprays, or oral parasite treatments. These treatments should be continued even once the fleas are gone as a preventative. Remember, though, that fleas can also be hiding on other pets or in soft furnishings and carpets around the house, so household treatments are also necessary.

FAQ’s About Cats Shaking Their Head

How do I know if my cat has ear mites or an infection?

The symptoms of ear mites and ear infections are very similar, and they both cause itchiness, scratching, and brown discharge in the ears. To decide whether there are ear mites, your veterinarian will need to look at a sample of debris from your cat’s ear. If the cause of the symptoms is ear mites, they’ll be able to see them crawling around amongst the ear wax when they look under the microscope. If they don’t see any ear mites, they can look for bacteria and choose an appropriate antibiotic.

Do indoor cats get ear mites?

Although it’s unusual, indoor cats can get ear mites. It’s most common for cats to get ear mites from other cats, including their mother, if they’re kittens. But some cats have small numbers of ear mites in their ears without showing any signs. Then, if their immune system is suppressed, the ear mites can grow out of control.

Do cat ear infections go away on their own?

Cat ear infections are usually caused by bacteria, and they need to be treated with antibiotics. Ear infections don’t go away on their own, and they can cause your cat a lot of pain. Therefore, if you think your cat might have an ear infection, it’s best to get them examined by a veterinarian as soon as possible.

Should You Be Worried If Your Cat is Shaking Their Head?

If your cat is shaking their head, it’s really important not to ignore it, especially if they have other symptoms or seem in pain.
