How to treat lice in a cat? - briefly
Apply a veterinary‑approved topical insecticide (e.g., fipronil, selamectin) according to the product instructions and simultaneously wash bedding, vacuum carpets, and treat the living area. Schedule a re‑examination after one week to confirm elimination and address any persistent infestation.
How to treat lice in a cat? - in detail
Lice infestations in felines require prompt identification and a systematic approach to eradicate the parasites and prevent recurrence.
First, confirm the presence of lice by examining the cat’s coat and skin. Adult lice and nymphs appear as tiny, tan to brown insects moving quickly through the hair. Look for itching, crusty patches, hair loss, or a “wet” appearance caused by lice saliva. A fine-toothed comb can collect specimens for microscopic confirmation if needed.
Second, select an appropriate ectoparasiticide. Options include:
- Topical spot‑on products containing fipronil, selamectin, or imidacloprid; apply directly to the skin at the base of the neck, following label dosage based on weight.
- Oral medications such as spinosad or afoxolaner; administer according to veterinary prescription, ensuring the cat’s weight is accurately measured.
- Shampoos and dips formulated with pyrethrins, permethrin (only for cats without known sensitivity), or malathion; wet the coat, lather thoroughly, leave for the recommended contact time, then rinse completely.
Third, treat the environment. Lice spend their entire life cycle on the host, but eggs may fall onto bedding, grooming tools, and surrounding surfaces. Wash all washable items in hot water (≥ 60 °C) and dry on high heat. Vacuum carpets, upholstery, and cracks where fallen debris may accumulate; discard the vacuum bag or clean the canister afterward.
Fourth, monitor the cat for adverse reactions. Common side effects include mild skin irritation, temporary lethargy, or reduced appetite. If signs of hypersensitivity, vomiting, or neurological disturbance appear, contact a veterinarian immediately.
Fifth, schedule a follow‑up examination 7–10 days after initial treatment. Re‑apply the chosen product if the label recommends a second dose, and reassess for any remaining lice or reinfestation.
Finally, implement preventative measures: maintain regular grooming, keep the cat’s living area clean, and use a long‑acting ectoparasiticide as part of routine health care. Consistent application reduces the risk of future outbreaks and supports overall feline well‑being.
