How are ear lice in cats treated? - briefly
Veterinarians treat feline ear lice with a single application of a prescription‑only topical acaricide—commonly selamectin, ivermectin, or a pyrethrin‑based ear solution—followed by thorough cleaning of the ear canal to remove debris and dead parasites. A repeat dose is usually administered after 7–10 days to ensure complete eradication.
How are ear lice in cats treated? - in detail
Ear lice infestations in felines require a systematic approach that combines accurate diagnosis, thorough cleaning, targeted medication, and environmental management.
First, confirm the presence of lice by examining the ear canal with a bright light and a otoscope. Look for live insects, nits attached to hair shafts, and dark debris. A veterinary laboratory may be consulted for microscopic identification if the visual assessment is ambiguous.
Second, cleanse the ear canal to remove debris and reduce the parasite load. Use a veterinarian‑approved ear cleaner containing a mild surfactant; apply the solution according to the label, massage the base of the ear for 30–60 seconds, then allow the cat to shake and wipe away excess fluid with a soft gauze. Repeat the cleaning process daily for three consecutive days.
Third, administer a parasiticide that is effective against lice. Options include:
- Topical spot‑on products (e.g., selamectin, imidacloprid + moxidectin). Apply the recommended dose directly to the skin at the base of the skull, avoiding the ear canal.
- Ear drops formulated for lice (e.g., pyrethrin‑based solutions). Administer the specified number of drops into each ear, then gently massage the base of the ear for one minute.
- Systemic oral medications (e.g., afoxolaner, fluralaner). Give the tablet at the dosage indicated for the cat’s weight; the drug circulates in the bloodstream and reaches the ear canal.
Fourth, treat all animals in the household simultaneously, even if they show no symptoms, to prevent reinfestation.
Fifth, disinfect the environment. Wash bedding, blankets, and soft toys in hot water; vacuum carpets and upholstery thoroughly; apply a residual spray to the home’s floor and baseboards according to the product’s safety guidelines.
Finally, schedule a follow‑up examination 10–14 days after the initial treatment. Re‑inspect the ears for live lice or nits; if any remain, repeat the cleaning and medication cycle. Persistent cases may require a different class of parasiticide or a longer treatment course.
By adhering to this protocol—diagnosis, ear cleaning, appropriate parasiticide administration, simultaneous treatment of cohabiting pets, environmental decontamination, and post‑treatment verification—ear lice infestations in cats can be resolved efficiently and with minimal risk of recurrence.
