If fleas won’t come off a cat, what should you do? - briefly
Apply a veterinarian‑approved flea treatment—topical, oral, or collar—and concurrently treat the environment with an insecticide spray or fogger to eradicate eggs and larvae. If the infestation remains, consult a veterinarian for alternative or prescription therapies.
If fleas won’t come off a cat, what should you do? - in detail
When a cat remains infested despite initial treatment, systematic action is required.
First, confirm the product’s suitability. Verify that the flea medication matches the cat’s weight, age, and health status; many spot‑on or oral treatments lose efficacy if applied incorrectly or on an unshaved coat.
Second, eliminate the source. Wash all bedding, blankets, and any fabric the animal contacts in hot water; dry on high heat. Vacuum carpets, rugs, and upholstery thoroughly, then discard the vacuum bag or clean the canister to prevent re‑infestation.
Third, treat the environment with a residual insecticide labeled for indoor use. Apply according to label directions, focusing on cracks, baseboards, and pet‑frequent zones.
Fourth, initiate a comprehensive therapeutic regimen for the cat:
- Topical adulticide – apply a new dose if the previous one was less than 30 days old and the label permits a repeat.
- Oral adulticide – use a product containing nitenpyram, spinosad, or a similar fast‑acting ingredient for immediate kill.
- Egg and larva control – administer a product containing insect growth regulator (IGR) such as methoprene or pyriproxyfen to stop the life cycle.
- Bathing – if the cat tolerates it, use a flea‑specific shampoo; repeat after 48 hours to target newly emerged fleas.
Fifth, schedule a veterinary examination. A professional can assess for underlying conditions (e.g., skin disease, allergy, immunosuppression) that may hinder flea removal, prescribe prescription‑strength medications, and provide a tailored follow‑up plan.
Finally, maintain a strict prevention schedule. Apply the chosen adulticide monthly, keep the home environment clean, and monitor the cat weekly for any signs of reinfestation. Consistent vigilance prevents recurrence and protects both animal and household health.
