Why Is My Cat Scratching His Ears and Shaking His Head

If you’re asking, “Why is my cat scratching his ears and shaking his head?”, you’re not alone. Ear scratching and head shaking are common signs of ear problems in cats and usually indicate irritation, infection, or parasites. While occasional scratching is normal, frequent or aggressive behavior should be addressed quickly to prevent pain and long-term damage.
Understanding the common causes of itchy ears in cats can help you know when to seek veterinary care and how to protect your cat’s ear health.

Common Causes of Ear Scratching and Head Shaking in Cats
Ear Mites in Cats
Ear mites are one of the most common causes of itchy ears in cats, especially in kittens and outdoor cats. These microscopic parasites live in the ear canal and cause intense irritation.

Signs of ear mites in cats include:
Constant ear scratching
Frequent head shaking
Dark, coffee-ground-like debris in the ears
Red or inflamed ear canals
Ear mites are highly contagious and require prescription treatment from a veterinarian.

Ear Infections in Cats:
Ear infections in cats may be caused by bacteria or yeast. Although less common than in dogs, feline ear infections can be painful and worsen if untreated.

Symptoms of a cat ear infection:
Head shaking or head tilting
Foul odor from the ears
Swollen or warm ears
Pain when the ears are touched
Chronic ear infections can lead to hearing loss or inner ear damage.

Allergies Causing Itchy Ears in Cats
Cat allergies--including food allergies, environmental allergens, or flea allergies—often cause ear inflammation and itching.

Allergy-related ear symptoms include:
Persistent ear scratching
Hair loss or scabs around the head and neck
Excessive grooming
Recurring ear infections
Managing allergies typically requires identifying the trigger with your veterinarian.

Excessive Ear Wax or Dirty Ears
Some cats naturally produce more ear wax. Wax buildup in cat ears can trap bacteria and debris, leading to irritation.

You may notice:
Visible wax or debris
Mild itching
Dirty or greasy-looking ears
Routine ear checks and proper cleaning using vet-approved ear cleaners for cats can help prevent problems.

Foreign Objects in a Cat’s Ear
Dust, plant material, or other debris can become lodged in the ear canal, causing sudden discomfort.

Signs include:
Sudden head shaking
Pawing at one ear
Sensitivity on one side of the head
Never attempt to remove foreign objects at home—this should be handled by a veterinarian.

Ear Injuries or Trauma
Scratching, fighting, or accidents can cause ear injuries in cats, leading to swelling or infection.

Watch for:
Redness or scabbing
Bleeding
A swollen ear flap (ear hematoma)
Prompt veterinary care helps prevent complications.

Ear Polyps or Growths in Cats
Less commonly, ear polyps or tumors can cause chronic ear irritation and head shaking.

Possible signs include:
Ongoing ear problems that don’t improve
Balance issues
Hearing changes
Persistent discharge
These conditions require diagnostic testing and treatment by a veterinarian.

When to See a Veterinarian for Cat Ear Problems
Contact your veterinarian if:
Your cat scratches his ears constantly
Head shaking lasts more than 24–48 hours
There is discharge, swelling, or a bad smell
Your cat shows pain or behavior changes
Early diagnosis prevents infections from becoming severe.

To reduce the risk of ear infections and ear mites in cats, follow these tips:
Check your cat’s ears weekly
Use parasite prevention year-round
Clean ears only when recommended by your vet
