How to diagnose ear ticks in a cat? - briefly

Examine the ear canal for small, dark, moving parasites attached to the skin, often accompanied by a crusty buildup or gritty sensation. Confirm their presence by gently pulling the ear flap and using a fine‑toothed comb or magnifying lens to visualize the ticks.

How to diagnose ear ticks in a cat? - in detail

Ear‑dwelling ticks in felines present with specific clinical indicators. Visible signs include small, dark‑colored organisms attached to the ear canal walls, swelling of the auricular tissue, and excessive cerumen that may appear brown or black. Cats often display frequent scratching or head shaking, which can signal an infestation.

Physical examination should begin with a thorough otoscopic inspection. The veterinarian inserts an otoscope gently into the external auditory meatus to visualize the canal surface. Tick attachment sites are identified by their rounded bodies and visible legs. Careful manipulation can detach superficial specimens for closer evaluation.

If visual confirmation is uncertain, the following diagnostic steps are recommended:

  • Collect a small sample of ear debris using a sterile swab or curette.
  • Place the material on a glass slide, add a drop of mineral oil, and examine under a low‑power microscope (10–20×) to detect tick morphology.
  • Submit the sample to a veterinary parasitology laboratory for species identification if the practitioner lacks microscopy equipment.

Additional tests may be warranted when secondary infections are suspected. Cytology of ear swabs can reveal bacterial overgrowth or yeast, guiding antimicrobial therapy. In cases of severe inflammation, cytological examination also helps differentiate tick infestation from other otic conditions such as ear mites or dermatitis.

Treatment protocols depend on the identified tick species and the extent of infestation. Common measures include:

  • Topical acaricides formulated for feline use, applied directly to the ear canal.
  • Systemic acaricidal medications administered orally or subcutaneously, following dosage guidelines.
  • Cleaning the ear canal with a veterinary‑approved solution to remove residual debris and reduce irritation.

Post‑treatment re‑examination after 7–10 days confirms eradication. Persistent signs may indicate incomplete removal or reinfestation, prompting repeat otoscopic assessment and possible adjustment of therapeutic agents.

Preventive strategies focus on environmental control. Regular inspection of the cat’s ears during routine health checks enables early detection. Maintaining a clean living area, reducing exposure to tick‑infested habitats, and applying veterinarian‑approved tick preventatives on a monthly basis lower the risk of recurrence.
