Summary

A cat ear infection, clinically known as otitis, is an inflammation of the ear canal. It may be limited to the outer ear (otitis externa) or affect deeper structures, such as the middle ear (otitis media) or the inner ear (otitis interna).

The deeper the infection travels, the more serious the consequences. While infections in cats are less frequent than in dogs, they're often more complex when they do occur.

Because of Dubai’s local climate and environment, cat ear infections are a serious concern. 

Early Signs

Healthy ears are typically pale pink, while infected cat ears look irritated and dirty.

Cats don't often show signs of pain, which is why we recommend taking a close look at even the smallest of indicators. Common ones include:

• Frequent head shaking or tilting

• Scratching at one or both ears

• Scabbing or hair loss

• Ear inflammation, redness, warmth, or visible swelling

• Foul odor emanating from the ear canal

• Ear discharge (yellow, brown, or black, often waxy or gritty)

• Sensitivity or pain when touched near the ears

• Changes in behavior like hiding, irritability, or seeming off

In severe cases, especially during middle and inner ear infections, cats may experience:

• Ataxia (loss of balance or trouble walking)

• Nystagmus (involuntary side-to-side eye movements)

• Uneven pupil size

• Walking in circles or disorientation

• Hearing loss

• Facial paralysis

Seek veterinary care without delay. Painful ear infections can progress quickly and cause ongoing discomfort and chronic problems. Early treatment is crucial.

Types of Ear Infections

Not all types are created equal. In most cases, outer ear infections can progress to middle and inner ear infections when left untreated.

Common Causes

Ear infections in cats are primarily caused by ear mites, bacteria and yeast, allergies, ear polyps, excessive ear wax, foreign bodies, and underlying diseases.

Ear Mites

Ear mites are the number one cause of cat ear infections. These problematic parasites cause intense itching, present dark, crumbly debris, and can easily spread from one cat to another. Ear mite infestations are common in Dubai, especially in kittens.

Bacterial or Fungal Infections

Cat ear infections develop from bacterial or fungal infections. These often arise when an underlying issue triggers inflammation or excess moisture. They're almost always a secondary reaction to a primary cause.

Allergies

Allergic reactions trigger inflammation in the ear canal, accelerating excess earwax production and creating a moist environment for bacterial and fungal overgrowth. This can come from fleas, food, and environmental allergens.

Allergies are a common concern in Dubai, especially due to the region’s climate, sandy and dusty environment, and year-round use of air conditioning, which brings mold and dust mites.

Ear Polyps

Tumors or growths can obstruct the ear canal, easily trapping moisture and wax that significantly contribute to cat ear infections.

Foreign Bodies or Trauma

Any foreign material, such as blades of grass, small toys, and sharp objects, can get lodged in the ear canal and cause irritation. This leads to swollen tissues, open cuts, and severe infections.

Underlying Conditions

Many systemic conditions, such as diabetes, autoimmune diseases, FeLV, and FIV, can make cats more susceptible to an ear infection. A weak immune system from a more serious underlying cause is a concern.

Which Cats Are at Risk?

Scottish Folds are particularly at risk because of their signature folded ears. They create a narrower canal that can more easily trap wax and moisture, leading to bacterial or fungal overgrowth.

Persians and Himalayan cats are also prone to ear infections because of their flat faces and skin folds.

Other long-haired cats are also at risk because their coat easily traps dirt, allergens, and debris.

Cat ear infections are also common for those with access to gardens, parks, and outdoor spaces.

Young cats, especially rescues or those without regular parasite control, are extremely vulnerable to ear mites, which lead to ear infections.

Additionally, cats with allergies or weakened immune systems are also at risk.
