Around 8/6, we realized that Feeby is suffering from fleas (part of another issue, as posted under 'Weird Behavior'). I had some Advantage II that I never used and applied it to her. House cleaning, flea combing, etc. began.
On 8/13, she went in to see her regular vet who said that Adv II is becoming ineffective and he recommended Bravecto, and suggested I start her on it immediately. I asked about overlapping the two treatments, and he said it was no issue because Adv II is a topical formula that enters a cat's sebaceous glands only, whereas Bravecto - although also labeled as a topical - is considered a trans-dermal treatment because it actually enters a cat's blood stream. This appears to be true after looking at hundreds of web sites.
There is an FDA warning about Bravecto possibly causing neurological issues in cats. But, none so on Adv II. There is some information on Adv II causing seizures, but mostly attributed to a cat ingesting it. My vet said that FDA does not regulate Adv II as it does Bravecto. Only the EPA does. This is because of the difference in skin only vs. blood stream.
So far, I have found zero evidence on flea resistance to Adv II - short of a 2014 post from a TCS member in Orlando whose vet told them the same thing. That member is no longer active. I also found an ongoing study regarding the lack of evidence of fleas becoming resistant to Adv II - the most recent being:
In 17-Year Study, Researchers Find Cat Flea Pesticide Remains Effective. The only disconcerting matter with this ongoing study is that Bayer (the maker of Adv II ) has contributed to it.
But, for now I am not giving her Bravecto and will stay the course with Adv II, along with all the other steps to take in getting rid of fleas in one's home.
Just wondering what others are experiencing??
