How can lice be removed from a domestic cat? - briefly
Apply a fine‑toothed comb to detach and collect the parasites, then administer a veterinarian‑approved lice treatment—either a topical insecticide or an oral medication—according to the product’s instructions. Ensure the cat’s environment is cleaned, washing bedding and vacuuming surfaces to prevent reinfestation.
How can lice be removed from a domestic cat? - in detail
Lice infestations in cats require immediate attention because the parasites feed on blood, cause irritation, and may lead to secondary skin infections. Effective eradication combines chemical treatment, mechanical removal, and environmental control.
A veterinarian‑prescribed topical insecticide, such as a pyrethrin‑based solution or a fipronil formulation, should be applied directly to the cat’s skin according to the product label. The dosage is calculated based on the animal’s weight; the medication is usually spread along the dorsal midline, extending to the tail base and flanks. Repeat applications are often scheduled 7–10 days apart to interrupt the life cycle.
Mechanical removal involves combing the coat with a fine‑toothed lice comb. The procedure should be performed on a damp coat to reduce discomfort. Starting at the head, run the comb through each section of hair, wiping the teeth with a disposable tissue after each pass. Collected insects are disposed of in sealed containers. Repeating this combing session daily for at least two weeks helps eliminate nymphs that emerge after the initial treatment.
Bathing with a medicated shampoo containing selamectin or a similar ectoparasiticide can supplement topical therapy. The cat’s fur is thoroughly wetted, the shampoo applied, lathered for the recommended contact time (usually 5–10 minutes), and rinsed completely. Dry the animal with a low‑heat dryer or a towel to prevent chilling.
Environmental decontamination reduces re‑infestation risk. All bedding, blankets, and soft toys should be washed in hot water (≥60 °C) and dried on high heat. Hard surfaces—floors, countertops, and carrier interiors—must be cleaned with a diluted household disinfectant or a veterinary‑approved spray. Vacuuming carpets and upholstery removes eggs and larvae; the vacuum bag or canister should be emptied immediately into a sealed bag.
A typical protocol may look like this:
- Veterinary examination to confirm lice species and rule out other skin conditions.
- Application of a prescribed topical insecticide (first dose).
- Daily combing with a lice comb for 14 days.
- Bath with medicated shampoo on day 3–5, if tolerated.
- Repeat topical treatment on day 10‑12.
- Full laundering of all washable items and thorough cleaning of the environment.
Monitor the cat for signs of irritation, excessive scratching, or adverse reactions to medication. If symptoms persist beyond two weeks, seek veterinary reassessment, as resistant lice strains or underlying dermatological issues may require alternative therapies.
