If you call Merial (the makers of Frontline and Frontline Plus) in the customer support department they will tell you not to do another dose of Frontline because that is what they are told to say to the public. Our clinic actually had a similar incident with a client recently like this only she didn’t think she got the Frontline Plus all the way on the skin. After talking with our Merial Rep (the guru who know the product better than the back of his hand), he said it was PERFECTLY SAFE to apply another dose of the Frontline (it had only been a week). He also stated that you could apply 3 of the 89-132# dog doses to a cat and it would be perfectly safe. If you want to apply another dose of Frontline after 2 weeks you certainly can and it won’t have any ill affects.

Three more things:
1: Make sure you get the product to the skin
2: Don’t give a bath 48 hours before or after applying the product, the way it is distributed through out the skin is through the sebaceous glands on the skin aka the oils. By giving a bath you are removing the mode of transportation for the Frontline, or removing the product itself.
3: Make sure you buy the product from a vet, they are the ONLY people that Merial sells to. They don’t sell to pet stores of any size or name, nor do they sell to online pet pharmacies. Any Frontline you find on a website is most often counterfeit. It is a popular product and many people find it easier to buy online than hop in the car and go to the vet and get it.

  • Do not reapply the Frontline (Topspot or Plus?). Do not use flea shampoo or dip as these are stripping the skin of necessary oils and moisture necessary to protect the skin and distribute the Frontline for 30 days.

    Ensure you are applying the Frontline directly to the skin, parting the hair, and NOT within 48 hours of water exposure, including rain, bath, etc.

    When we still see many fleas, but also dead fleas in the cats bed or any area they frequent, then we know the Frontline is battling a high environmental infestation. Frontline Plus is better than Frontline Topspot and only a few dollars more to sterilize the eggs and kill larva, not just the adults as Topspot is only an adulticide. High flea burdens must be consistently treated by applying Frontline Plus every 4 weeks throughout temperate climate months (in the South year round, in the Northeast March-October, in the West April-August and so on).

    Frontline Spray can be used in the home environment. EctoKyl IGR Spray as well. Wash all linens and vacuum to kill eggs/larva in carpet just prior to applying the sprays. Placing some flea powder or an old-school flea collar in your vacuum bag or container will kill any inside and then immediately dispose! Powder and collar aren’t effective/safe for cats but fine for your vacuum.

    Aventis Sevin Dust and other MAMMAL safe treatments are available for the lawn, in case you are tracking in flea eggs/larva or your cat goes out at all. Mammal friendly is necessary because your cat grooms itself, may eat off the ground/floor, and many lawn insecticides are toxic to birds/mammals necessary to a healthy yard.

    Bad infestations take longer to eradicate and multiple venues of “attack” so to speak. Flea bombs are ineffective as they can’t access areas under furniture and aren’t made specifically tolerant and safe for mammals (such as your cat and you).

  • NO no no no! These treatments are pesticides and are dangerous and toxic if used too close together. A 4 week dose is for four weeks, NOT two. If you give more it will cause permanent liver damage and potentially kill the cat. You do not play around with this stuff.

    The fleas in your environment have not bitten the cat so they aren’t dead. They also probably laid eggs which are hatching and you’re seeing that as well. Just let the cat be, he’s protected and any flea biting him will die.

    YOU on the other hand, can get the vacuum out and vacuum along the floor boards, the carpet, any cracks in the wood floor, and even the furniture every day—this kills any flea it sucks up. They do not survive the trip up the hose of the vacuum.

  • After 2 wks its ok to do a flea dip bath but NOT frontline, that has to wait 4 weeks. Also vaccume and get rid of the eggs all over your house, you can spray with some bug sprays to get rid of fleas, wash any bedding the cat has been on, you may need to bomb your house. (with a bug bomb not an explosive)
  • Give him a flea bath, and kill them inside your home, Bug Bombs or something. Probably not on another treatment. Did you apply the first on properly?
  • Yes, but consider Frontline Plus next time.

    Frontline kills fleas within the first 24 hours for the first two weeks, and 48 hours in weeks 3-4. That is not quick enough to stop the egg cycle. However, Frontline Plus has a second ingredient that will stop the eggs from hatching. The active ingredient in Frontline is non-toxic.

    You also have to treat the environment to stop the flea egg cycle. The flea egg cycle is 3-8 weeks.

    There is another option. Revolution kills fleas within 15-30 minutes after biting, as it is systemic. It also prevents heartworms, ear mites, and a couple of intestinal parasites, a huge bonus for cats that won’t eat the monthly Heartgard heartworm preventive, but is ineffective for ticks.

    No it is not yet safe for your cat to have another treatment now it’s a little bit too soon. Wait another 2 weeks. Are you also treating the house with flea spray such as “acclaim”? If not you need to buy this spray and use it on your pets bedding and use it to treat your carpets. Fleas and their eggs linger around in carpets and furniture and then re-hatch and re-infest your cat. The only way to get rid of these fleas for good is to treat both your home and your cats for fleas.
