What should be done when a cat has many fleas? - in detail
A cat suffering from a severe flea infestation requires immediate, systematic action to eliminate parasites and prevent recurrence.
First, isolate the animal in a clean, flea‑free room. Remove all bedding, toys, and washable items; wash them in hot water (≥ 60 °C) and dry on high heat. Vacuum the entire area, then discard the vacuum bag or empty the canister outdoors.
Next, treat the cat directly:
- Apply a veterinarian‑approved topical or oral flea product according to the label dosage. Products containing fipronil, imidacloprid, selamectin, or nitenpyram are effective for rapid kill and ongoing protection.
- Administer a prescription‑only medication if the cat is pregnant, nursing, or has health complications; consult a veterinarian for appropriate options.
- Groom the animal with a fine‑toothed flea comb. Comb each section for several minutes, dipping the comb in soapy water after each pass to drown captured fleas.
Simultaneously, address the environment:
- Treat the home with an insecticide spray or fogger labeled for indoor use against adult fleas and larvae. Follow safety instructions, especially regarding pets and children.
- Apply a monthly environmental flea control product (e.g., diatomaceous earth or insect growth regulator granules) to carpets, cracks, and pet sleeping areas.
- Continue regular vacuuming for at least four weeks, focusing on floors, upholstery, and pet crates.
Monitor progress:
- Check the cat daily for live fleas or signs of irritation. Repeat topical treatment after two weeks if recommended by the product label.
- Maintain a preventive regimen—monthly topical or oral preventatives, routine combing, and clean living spaces—to avoid future infestations.
If the cat shows excessive scratching, skin lesions, or anemia, seek veterinary care promptly for possible secondary infections or supportive therapy.
