What is the ear mite called in cats? - in detail
The parasite that infests feline ears is the species Otodectes cynotis. It is a microscopic, eight‑legged arachnid that lives on the surface of the ear canal and surrounding hair follicles. Adult mites measure 0.2–0.4 mm, feed on skin debris and ear secretions, and reproduce rapidly, with a life cycle of approximately three weeks.
Clinical signs appear within days of infestation. Common observations include:
- Intense scratching or head shaking
- Dark, waxy discharge resembling coffee grounds
- Redness and inflammation of the ear canal
- Secondary bacterial or fungal infection if left untreated
Diagnosis relies on otoscopic examination, where live mites, eggs, and fecal pellets are visible. Microscopic analysis of ear swabs confirms species identification.
Effective management consists of:
- Topical acaricidal preparations (e.g., selamectin, moxidectin, or ivermectin formulations) applied directly to the ear canal.
- Systemic therapy for severe cases, using oral or injectable macrocyclic lactones.
- Thorough cleaning of the ear to remove debris before medication application.
- Re‑treatment after 7–10 days to eliminate newly hatched mites.
Preventive measures include regular ear inspections, maintaining dry ear environments, and administering routine prophylactic ectoparasite preventatives recommended by a veterinarian. Early detection and prompt treatment minimize discomfort and reduce the risk of complications.
