How should a flea‑infested cat be treated? - in detail

Treating a cat plagued by fleas requires a systematic approach that eliminates adult insects, interrupts the life cycle, and prevents re‑infestation.

First, confirm the presence of fleas by inspecting the coat and skin. Use a fine‑toothed flea comb on damp fur; move the comb slowly from the head toward the tail, rinsing after each pass. Visible insects or flea dirt (small dark specks) indicate an active infestation.

Second, initiate immediate adult‑kill therapy. Options include:

  • Spot‑on products containing fipronil, imidacloprid, or selamectin; apply to the base of the neck as directed.
  • Oral medications such as nitenpyram (rapid kill) or a monthly systemic like afoxolaner; dose according to body weight.
  • Topical sprays or shampoos with pyrethrins or pyrethroids; use only if the cat tolerates bathing.

Apply the chosen product following the manufacturer’s instructions, ensuring the cat’s skin is dry and free of excess oil. Repeat the treatment according to the product’s schedule, typically every four weeks, to maintain efficacy.

Third, address immature stages in the environment. Effective measures include:

  • Vacuuming carpets, upholstery, and bedding daily for two weeks; discard vacuum bags promptly.
  • Washing all washable fabrics in hot water (minimum 60 °C) and drying on high heat.
  • Applying a household insect growth regulator (IGR) such as methoprene or pyriproxyfen to carpets, cracks, and baseboards; follow label guidelines to avoid toxicity.
  • Using a flea fogger or bomb only in severe cases, after removing pets from the area and ventilating thoroughly.

Fourth, provide supportive care to the cat. Administer a mild, veterinary‑approved anti‑inflammatory or antihistamine if the animal shows signs of irritation or allergic dermatitis. Monitor for anemia, especially in kittens or debilitated adults; seek veterinary intervention if pale mucous membranes or lethargy develop.

Finally, establish a long‑term prevention plan. Maintain regular monthly preventatives, keep the home environment clean, and limit outdoor exposure during peak flea seasons. Routine veterinary check‑ups should include flea status assessment and adjustment of preventive products as needed.
