What should be used to treat ear mites in a cat's ear? - briefly
Topical acaricidal agents such as selamectin, moxidectin or ivermectin, applied according to veterinary guidance, eradicate ear mites in felines. Subsequent ear cleaning with a veterinarian‑approved solution removes debris and reduces the risk of reinfestation.
What should be used to treat ear mites in a cat's ear? - in detail
Ear mite infestations in felines require a three‑step protocol: accurate diagnosis, thorough aural cleaning, and administration of a proven acaricide. Veterinarians confirm the presence of «Otodectes cynotis» by visual inspection of dark, moving debris and microscopic examination of ear swabs. Once identified, the ear canal is flushed with a pH‑balanced solution to remove debris and improve drug contact.
Effective topical acaricides include:
- Selamectin (e.g., Revolution) – applied once monthly; dosage based on body weight; provides systemic and local activity against ear mites.
- Ivermectin – formulated for otic use; a single dose of 0.5 mg/kg applied directly into the ear canal; contraindicated in certain breeds (e.g., collies) due to MDR1 sensitivity.
- Milbemycin oxime – oral formulation; dosage of 0.5 mg/kg administered once; offers systemic control of mite populations.
- Lime sulfur dip – 1 % solution; applied to the ear canal and surrounding skin; effective for severe cases but may cause irritation; requires protective eyewear for the practitioner.
- Moxidectin – topical spot‑on preparation; 1 % solution; applied at the base of the skull; provides long‑lasting protection against ear mites and other parasites.
Systemic medications (selamectin, milbemycin, moxidectin) also address concurrent intestinal and ectoparasitic infections, reducing the need for multiple products. Topical agents (ivermectin, lime sulfur) act directly within the ear canal, offering rapid symptom relief.
Treatment schedules typically involve a repeat dose 7–10 days after the initial application to eliminate newly hatched larvae. Follow‑up examinations confirm eradication; absence of live mites on otoscopic inspection indicates successful therapy.
Owners should monitor for adverse reactions: excessive erythema, swelling, or discharge may signal hypersensitivity. In such events, discontinue the product and consult a veterinarian promptly. Continuous preventive care—regular ear cleaning and scheduled antiparasitic treatments—maintains ear health and prevents reinfestation.
