How to disinfect a cat of fleas? - in detail
Eliminating flea infestations from a cat requires a systematic approach that combines topical treatments, environmental control, and preventive measures.
First, select an appropriate ectoparasiticide. Options include spot‑on products containing fipronil, imidacloprid, or selamectin; oral medications such as nitenpyram or afoxolaner; and flea collars with synergistic chemicals. Verify the product’s label for species compatibility, weight range, and dosage frequency. Apply spot‑on solutions directly to the skin at the base of the neck, avoiding the eyes and mouth. Administer oral tablets with food to ensure rapid absorption. Replace collars according to manufacturer recommendations.
Second, treat the living environment. Wash all bedding, blankets, and grooming tools in hot water (minimum 60 °C) and dry on high heat. Vacuum carpets, upholstery, and cracks in flooring; immediately discard the vacuum bag or clean the canister. Apply a flea growth regulator (e.g., methoprene or pyriproxyfen) to carpets and cracks, following the product’s concentration guidelines. For severe infestations, consider a professional residual spray that targets adult fleas and immature stages.
Third, repeat treatments on the animal. Most spot‑on and oral products maintain efficacy for 30 days; however, a second application is recommended after 7–10 days to interrupt the life cycle. Monitor the cat for adverse reactions such as excessive salivation, skin irritation, or lethargy; discontinue use and consult a veterinarian if symptoms appear.
Finally, implement long‑term prevention. Maintain a regular dosing schedule, keep the home environment clean, and limit outdoor exposure during peak flea activity periods. Use a year‑round preventive product when the cat spends time outdoors or lives in a multi‑pet household.
