Otitis Externa & Media in Cats: Vet Guide 🐱👂 2025

By Dr Duncan Houston BVSc, veterinarian & founder of Ask A Vet.

Otitis externa is inflammation or infection of the external ear canal; when it progresses, otitis media involves the middle ear behind the eardrum. Both can cause intense discomfort and hearing loss in cats. This guide explores:

🔍 What Are Otitis Externa & Media?

Otitis externa affects the outer canal and is common; otitis media is deeper, behind the eardrum, often more serious.

Externa: painful, itchy, discharge
Media: potential head tilt, pain, balance issues

🧬 Causes & Risk Factors

Allergies—flea, food, environment
Ear mites (Otodectes cynotis) in kittens and indoor cats
Bacteria & yeast—often secondary to moisture
Foreign bodies—grass awns, debris
Polyps or tumors in middle ear
Trauma or systemic disease—hypothyroidism

🚨 Signs & Symptoms

Shaking head, scratching ears
Odor, dark wax, crusting
Pain when touching ears; ear canal swelling
Ear discharge—black, yellow, bloody
Signs of otitis media: head tilt, circling, balance loss
Sometimes hearing loss or facial nerve paralysis

🔍 Diagnosis & Evaluation

Otoscopic exam—look at ear canal and eardrum
Ear cytology—to identify mites, yeast, bacteria
Culture from deeper canal—when infection is resistant
Imaging (X‑ray, CT) for middle ear changes
Ruling out polyps, masses, systemic illness

🛠️ Treatment Options

Otitis Externa

Ear cleaning with safe agents
Topical meds: antibiotic/steroid drops (e.g., gentamicin, miconazole)
Systemic antibiotics if deep or severe
Mite treatment if present
Anti-allergy strategy: hypoallergenic diet, flea control

Otitis Media

Extended antibiotic course
Possible myringotomy—flush middle ear
Polyp removal via surgery
Long-term care for recurrent cases

Ear Polyps/Tumors

Surgical removal + histopathology
Follow-up imaging to monitor recurrence
Reconstructive options for chronic cases

📆 Prognosis & Follow-Up

Externa: often curable in 1–2 weeks
Media: may require 4–6 weeks of treatment
Recurrent cases need allergy investigations
Hearing may or may not fully recover
Monitor with rechecks and cytology

🏠 Home Care & Prevention

Regular ear checks and cleaning
Avoid moisture—dry ears after baths
Maintain flea control and hypoallergenic nutrition
Watch for signs and seek early treatment
