How can lice be removed from cats? - in detail
Lice infestations in felines are diagnosed by observing small, wing‑less insects clinging to the fur, especially along the neck, base of the tail, and behind the ears. Adult cat lice are about 2–3 mm long, reddish‑brown, and move slowly. Their presence often causes itching, hair loss, and a scaly skin surface.
Effective eradication requires a combination of direct treatment and environmental management. The following protocol is widely accepted by veterinary professionals:
- Topical insecticides – Apply a veterinarian‑approved spot‑on product containing fipronil, selamectin, or imidacloprid directly to the skin at the base of the neck. Follow the label dosage based on the cat’s weight; repeat the application after 7–10 days to interrupt the lice life cycle.
- Medicated shampoos – Use a lice‑specific shampoo containing pyrethrins or pyrethroids. Wet the animal thoroughly, lather the solution, and leave it in contact for the recommended time (usually 5–10 minutes) before rinsing. Repeat every 3–4 days for two weeks.
- Oral systemic agents – In cases of severe infestation, a veterinarian may prescribe oral ivermectin or a milbemycin oxime formulation. Dosage must be calculated precisely; improper use can be toxic.
- Environmental decontamination – Wash all bedding, blankets, and removable fabrics in hot water (≥60 °C) and dry on high heat. Vacuum carpets, upholstery, and storage areas; discard vacuum bags or clean the canister promptly. Treat the household with a residual spray labeled for lice control on surfaces where the cat spends time.
- Follow‑up examination – Re‑examine the animal after the second treatment round. Look for remaining lice, nymphs, or signs of secondary skin infection. If any insects persist, repeat the chosen therapy or switch to an alternative class of insecticide.
Precautions: Do not use products intended for dogs or humans, as they may contain concentrations harmful to cats. Avoid applying treatments to pregnant or nursing animals without veterinary approval. Monitor the cat for adverse reactions such as excessive salivation, lethargy, or skin irritation; contact a veterinarian immediately if symptoms appear.
Preventive measures include regular grooming, routine flea and tick preventatives that also affect lice, and maintaining a clean living environment. Early detection and prompt, targeted treatment minimize discomfort and reduce the risk of reinfestation.
