Ear Mites in Cats
Ear mites are tiny parasites that live inside a cat’s ear canal and feed on skin debris and wax. They are a common cause of itchy ears in cats, particularly in kittens and outdoor cats. The most common ear mite in cats is Otodectes cynotis.
Ear mites spread easily through close contact with other cats and dogs. Mites can also survive for a short time in the environment, including bedding and grooming areas.
They can cause significant irritation and inflammation inside the ears and, without treatment, may lead to secondary ear infections. Most cats with ear mites develop intense itching and produce a dark ear discharge. Some cats may also shake their head frequently or develop small scratches around the ears from excessive scratching.
Ear mites are usually diagnosed during a veterinary examination and are typically straightforward to treat. Early treatment helps relieve discomfort and prevents complications.

Ear Mites in Cats: Symptoms, Treatment and Prevention
Symptoms of ear mites in cats
Cats with ear mites usually develop itchy and irritated ears. Symptoms may affect one or both ears and can range from mild to severe. Common symptoms include:
- Itching the ears
- Head shaking
- Dark ear discharge
- Red or inflamed ears
- Sensitivity around the ears
Some cats may only show mild symptoms, especially early on.
When to contact your vet
You should contact your vet if your cat is scratching their ears, shaking their head frequently, or developing ear discharge. Ear problems can be uncomfortable and may worsen without treatment.
A veterinary examination is important because other conditions, including bacterial or yeast infections, can cause similar symptoms. Early treatment can help relieve irritation and reduce the risk of complications.
Diagnosis of ear mites in cats
Ear mites are usually diagnosed during a veterinary examination. Your vet will examine your cat’s ears and may use an otoscope to look inside the ear canal.
A sample of ear debris may also be examined under a microscope to confirm the presence of mites. Your vet will check for signs of inflammation or secondary infection at the same time.
Treatment for ear mites in cats
Ear mites are usually treated with prescription spot-on parasite treatment. Your vet may also recommend cleaning the ears and treating any secondary infection or inflammation.
Because ear mites spread easily between pets, other cats and dogs in the household may also need treatment.
Most cats respond well to treatment and improve quickly once the mites are eliminated.
Prevention of ear mites in cats
Regular parasite control can help reduce the risk of ear mites in cats. Keeping your cat’s ears clean and monitoring for early signs of irritation may also help identify problems sooner.
Because ear mites spread through close contact, treating affected pets promptly can help prevent transmission to other animals in the household. Routine veterinary check-ups are also useful for maintaining good ear health.
Outlook for cats with ear mites
The outlook for cats with ear mites is usually very good with prompt treatment. Most cats recover quickly once the mites are eliminated and any inflammation or infection has been treated.
Without treatment, ear mites can lead to ongoing irritation, secondary infections, and discomfort. Early veterinary care helps reduce the risk of complications and supports a faster recovery.
