What should be done if a cat constantly has fleas? - in detail
A cat that repeatedly shows signs of flea infestation requires a systematic approach that addresses the animal, the home environment, and future prevention.
First, confirm the presence of fleas by inspecting the coat, especially around the neck, tail base, and belly. Use a fine‑toothed flea comb; any live insects or flea dirt (small black specks) indicate an active problem.
Second, begin treatment on the cat. Choose a veterinarian‑approved product—topical spot‑on, oral medication, or a collar—based on the cat’s age, weight, and health status. Apply or administer the product exactly as directed, ensuring full coverage of the skin. If the cat has a severe infestation, a short course of a fast‑acting adulticide may be necessary, followed by a monthly maintenance dose.
Third, eliminate fleas from the surroundings. Wash all bedding, blankets, and removable fabrics in hot water (≥ 130 °F) and dry on high heat. Vacuum carpets, rugs, and upholstered furniture thoroughly; discard the vacuum bag or clean the canister immediately. Treat the home with an environmental flea spray or fogger that contains an insect growth regulator (IGR) to interrupt the life cycle. Repeat the treatment after 7–10 days to target newly emerged adults.
Fourth, address outdoor areas if the cat has access outside. Trim grass and weeds, remove debris, and apply a suitable outdoor flea control product to shaded, sheltered zones where the cat may rest.
Fifth, implement preventive measures. Continue monthly prophylactic medication year‑round, even when fleas are not observed. Regularly comb the cat with a flea comb to detect early re‑infestation. Keep the cat’s environment clean and limit contact with untreated animals.
Finally, monitor the situation. Record any signs of itching, skin irritation, or visible fleas for at least four weeks after treatment. If fleas persist despite following these steps, schedule a veterinary re‑evaluation to rule out resistance, underlying health issues, or improper product usage.
