What should be given to a cat for fleas? - in detail
Effective flea control for a cat requires a combination of medication, topical products, and environmental measures.
Topical treatments are applied directly to the skin at the base of the skull. Products such as fipronil, imidacloprid, selamectin, or selamectin‑based combos eliminate adult fleas and prevent new infestations for up to a month. Apply the correct dose based on the animal’s weight; excess can cause toxicity.
Oral medications provide systemic action. FDA‑approved options include nitenpyram (rapid kill, 24‑hour effect), afoxolaner, fluralaner, or sarolaner, which maintain protection for 30‑90 days depending on the formulation. Tablets must be given with food to ensure absorption. Dosage is weight‑specific; mis‑dosing can lead to neurological signs.
Flea collars deliver continuous low‑dose exposure. Modern collars contain imidacloprid and flumethrin, offering 8‑month protection. Ensure the collar fits snugly but allows room for two fingers between collar and neck.
Environmental control eliminates flea stages in the home. Steps include:
- Vacuum carpets, upholstery, and pet bedding daily; discard vacuum bags or clean canisters immediately.
- Wash all washable bedding in hot water (≥ 60 °C) and dry on high heat.
- Apply a regulated insect growth regulator (IGR) such as methoprene or pyriproxyfen to carpets and cracks; these agents prevent eggs and larvae from maturing.
- Treat indoor areas with a residual spray labeled for indoor use, following label instructions for concentration and re‑application intervals.
Veterinary consultation is essential before starting any regimen. The vet will confirm the cat’s health status, rule out contraindications (e.g., liver disease, pregnancy), and select a product compatible with the cat’s age and weight. Prescription‑only products, such as certain oral isoxazolines, should be obtained through a licensed professional.
Monitoring after treatment includes checking for live fleas on the cat and in the environment for at least two weeks. If fleas persist, reassess dosage, product choice, and environmental measures. Adjustments may involve rotating active ingredients to prevent resistance.
