Here's my two cents. Two Drops. I know I have seen it posted to use
the cat/kitten amount. It was ten years ago the first time I had to
use a flea control and at that time it was suggested only two drops of
Advantage. I have followed that prescribed amount ever since and not
had a flea problem despite other animals coming in from the yard. I
have also used Frontline in the same amount. In using only a couple of
drops I have not found that it needs to be applied more frequently.
There you have my two cents - two drops, works on masters.
