I can't get rid of fleas on a cat; what should I do? - briefly
Use a veterinarian‑prescribed topical or oral flea treatment and simultaneously clean the environment by washing bedding, vacuuming carpets, and applying an approved environmental insecticide. Repeat the treatment according to the product schedule to interrupt the flea life cycle and prevent reinfestation.
I can't get rid of fleas on a cat; what should I do? - in detail
Fleas persist on a feline when treatment is incomplete or resistant. Eliminate the infestation by addressing the animal, its environment, and ongoing prevention.
-
Select a veterinarian‑approved adulticide: spot‑on formulations (e.g., fipronil, imidacloprid), oral tablets (e.g., nitenpyram, spinosad), or collars containing selamectin or flumethrin. Apply according to label instructions; repeat as required for the full life cycle (typically 30 days).
-
Bathe the cat with a flea‑specific shampoo if tolerated. Shampoo removes adult insects and reduces irritation. Rinse thoroughly and dry to prevent skin damage.
-
Treat all household bedding, carpets, and upholstery with a flea‑targeted spray or fogger containing insect growth regulator (IGR) such as methoprene or pyriproxyfen. Follow manufacturer safety guidelines; vacuum before and after application, then discard vacuum bags.
-
Wash removable fabrics (blankets, pillow covers) in hot water (≥ 60 °C) and dry on high heat. For non‑washable items, apply a steam cleaner to penetrate fabric fibers.
-
Maintain regular grooming with a fine‑toothed flea comb. Comb daily for two weeks, discarding captured fleas into soapy water.
-
Implement monthly preventive medication for the cat. Options include topical spot‑ons, oral chewables, or long‑acting collars. Consistency prevents reinfestation from eggs or larvae that survive environmental treatment.
-
Schedule a veterinary examination if fleas persist after two treatment cycles, if the cat shows signs of anemia, skin infection, or allergic dermatitis. The veterinarian may prescribe prescription‑strength products or conduct a flea allergy test.
-
Limit outdoor exposure during peak flea season (spring–early autumn). Keep the yard free of tall grass and use a pet‑safe yard spray if necessary.
Following these measures systematically removes existing fleas, interrupts the development of new generations, and establishes a barrier against future infestations.
