Thanks for using Petco Pet Education Center, formerly Petcoach! Thankfully, you have a few options here. I recommend you consider using a product called Capstar which is to kill a lot of fleas at once to complement a flea preventative product like Advantage. You can go ahead and give another dose of Advantage now as well. I would not give up on Advantage just yet. Continue to use it for now as this flea may be was a one time occurrence and the Advantage was still being effective. Another option is switching to Bravecto now though again Advantage may still be effective so it may be best to exhaust its use. Good luck and have a great day!

I would not recommend it as the doses are specifically formulated for weight and species. There is no way to really know how much medication you are giving. In my experience, cats tend to react much worse when the wrong dosage is given. I would be very leary of an online chart for adjusting dosages, unless it comes directly from the manufacturer, which I highly doubt that it does. You can also try checking with local shelters and veterinary clinics that may be willing to donate some products. It's worth a try to ask. I hope this helps, best of luck!

I'm sorry to hear you've had trouble finding an effective flea med! Most over-the-counter options are not very effective in my experience, including Advantage - although it's probably the best of the currently available OTC options! Flea collars do not work well, and can often be toxic to cats. Instead, I would recommend getting a prescription flea medication like Revolution or Bravecto from your veterinarian. This will be safe for your kitty, and much more effective. If it's been at least 1-2 weeks since you applied the Advantage, it should be safe to go ahead and use a new medication from your vet.

Advantage treatment is a good start. If your kitty has flea allergies it is necessary to keep fleas from biting her. So: Unfortunately fleas only hop on the body of your pet when they want to feed, then they hop off again and stay in your pet's environment. So you need to treat all pets in the household as well as the environment (which contains the fleas, their eggs and larvae). Flea treatment: 1) Get some flea medication such as a Flea spray or a spot on from a pet shop or your veterinarian (Advantage is fine) and apply monthly 2) get flea powder, put some in your vacuum cleaner bag and vacuum your house and furniture and also non-carpeted areas frequently to remove flea larvae and eggs which live off house dust. Dispose of the bag in the trash outside. Hot-wash all the pet's bedding, If you do this diligently for a few months you will get rid of the fleas.

If you want an effective product please use one of newer ones like Cheristin. I don't think you will get any better results with Advantage. It is recommended to wait a minimum of 3 weeks between product applications. https://worldtails.securevetsource.com/itemView/view/198944_HomeDelivery.pml?productId=115569 While you wait you can get Capstar and give him that every couple days if need be. One pill lasts 24 hours but will kill everything on him. https://www.petco.com/shop/en/petcostore/product/capstar-flea-tablets-for-cats-2-25-lbs You also need to treat the house or the fleas will keep getting on him. I recommend Knockout Spray ES: https://www.chewy.com/virbac-knockout-es-area-treatment/dp/53856
