How to cure lice on a cat? - briefly
Apply a veterinarian‑approved lice shampoo or topical insecticide and comb the coat thoroughly to remove remaining parasites. Clean bedding, grooming tools, and the living area to prevent reinfestation.
How to cure lice on a cat? - in detail
Lice infestations in felines are caused primarily by the chewing louse Felicola subrostratus. These parasites attach to the hair shaft, feed on skin debris, and provoke itching and hair loss. Prompt identification prevents secondary infections and reduces discomfort.
Accurate diagnosis requires a thorough physical examination. A fine‑tooth comb or a flea comb should be run through the coat, especially along the neck, back, and tail base. Collected material is examined under magnification to confirm the presence of adult lice or nymphs. Skin scrapings may be taken if dermatitis is suspected.
Effective treatment combines direct parasite eradication, environmental decontamination, and supportive care.
- Topical insecticides: products containing fipronil, selamectin, or imidacloprid are applied according to label instructions, covering the entire body from the head to the tail tip.
- Oral medications: a single dose of a macrocyclic lactone (e.g., milbemycin oxime) or a systemic insecticide (e.g., spinosad) eliminates lice residing on the skin and in the hair shaft.
- Shampoo therapy: a medicated shampoo with pyrethrins or chlorhexidine is used after the first topical or oral dose, leaving the lather on the coat for the recommended duration before rinsing.
- Environmental control: all bedding, blankets, and grooming tools are washed in hot water (≥ 60 °C) or placed in a sealed bag for two weeks. Vacuuming of carpets and upholstery removes detached insects and eggs.
Supportive measures include treating inflammation with a short course of corticosteroids or antihistamines if severe itching persists, and providing a balanced diet to promote coat health.
Preventive strategies reduce the risk of recurrence. Regular application of a year‑round ectoparasite preventive, routine grooming with a fine comb, and periodic inspection of the coat are essential. Maintaining a clean living environment, limiting contact with untreated outdoor animals, and promptly treating any identified infestations safeguard the cat’s health.
Re‑examination two weeks after the initial treatment confirms eradication. If live lice are still detected, a second round of the chosen medication, following the same protocol, is recommended. Continuous monitoring for at least one month ensures that the life cycle is fully interrupted and that reinfestation does not occur.
