If you’re a cat owner, you know how sensitive your feline friend’s ears can be. But did you know one of the most common culprits behind itchy, inflamed, and dirty ears is a tiny parasite known as the ear mite?
Cat ear mites are tiny parasites causing itching, dark discharge, and irritation in cats’ ears. Prompt diagnosis and treatment are essential.
These microscopic pests can wreak havoc on your cat’s health if left untreated. In this comprehensive guide, we’ll cover everything you need to know about cat ear mites from identifying signs and symptoms to treatment options and prevention strategies.
What Are Cat Ear Mites?
Ear mites, scientifically known as Otodectes cynotis, are highly contagious external parasites that live in the ear canal and on the surface of cats’ skin.
These tiny, spider-like creatures feed on ear wax, oils, and skin debris, causing significant irritation and inflammation. Though they are barely visible to the naked eye, their presence can cause your cat severe discomfort.
Key Characteristics:
- Size: Less than 0.5 mm
- Color: White to pale gray
- Location: Ear canals, outer ear, and surrounding skin
- Lifespan: Approximately 3 weeks, with rapid reproduction
How Do Cats Get Ear Mites?
Ear mites spread mainly through direct contact with other infested animals. It’s incredibly common in multi-pet households, animal shelters, and among outdoor cats.
These mites can also be transferred via bedding, grooming tools, or contact with contaminated surfaces.
Animals prone to ear mites:
- Cats (especially kittens)
- Dogs
- Ferrets
- Rabbits
Common Symptoms of Cat Ear Mites
While ear mites themselves are hard to spot without a microscope, their effects on your cat are very noticeable. Here’s what to watch for:
⚠️ Signs and Symptoms:
- Frequent ear scratching
- Head shaking or tilting
- Dark, crusty, or waxy ear discharge (often coffee ground-like)
- Red, inflamed ear canal
- Foul odor from ears
- Hair loss around the ears
- Restlessness or irritability
- Secondary ear infections
Left untreated, ear mite infestations can lead to permanent ear damage or spread to other parts of the body.
How Are Ear Mites Diagnosed?
A veterinarian will typically:
- Perform a physical ear examination
- Collect a sample of ear debris
- Examine the sample under a microscope for live mites or eggs
Sometimes, an otoscope is used to look directly inside the ear canal.

Can Humans Get Ear Mites from Cats?
