What danger does an ear mite pose to a cat? - briefly

Ear mites irritate the ear canal, causing itching, inflammation and secondary bacterial or fungal infections that can impair hearing. Untreated infestations may damage ear tissue and lead to permanent hearing loss.

What danger does an ear mite pose to a cat? - in detail

Ear mites (Otodectes cynotis) inhabit the external auditory canal of felines, feeding on skin debris and secretions. Their activity triggers intense irritation, leading to excessive scratching and head shaking. Persistent inflammation can cause:

  • Thickened, reddened ear tissue
  • Accumulation of dark, waxy debris (“cerumen”) that may become malodorous
  • Secondary bacterial or yeast infections due to disrupted skin barrier
  • Painful ulcerations or crust formation
  • Permanent damage to the ear canal, resulting in reduced hearing or complete deafness

If left untreated, the chronic inflammatory process can spread to adjacent structures, such as the pinna and surrounding skin, producing dermatitis. In severe cases, systemic effects may arise, including weight loss and decreased immune response, particularly in young, elderly, or immunocompromised cats.

Behavioral consequences include increased aggression, anxiety, and decreased appetite, all stemming from constant discomfort. The infestation also poses a transmission risk to other household pets, facilitating rapid spread within multi‑animal environments.

Prompt veterinary assessment, microscopic examination of ear swabs, and appropriate acaricidal therapy are essential to halt tissue damage, restore auditory function, and prevent complications. Regular cleaning and preventive treatments reduce recurrence and protect overall feline health.
