Is it harmful to use frontline spot on flea treatment 3 days early?
I am told the effects wear off after about 3 weeks and it wont hurt to apply it again early. You might also put some on the cats back just before the tail because fleas love that area, it’s hard for the cat to get to that part. You might also try switching it out with advantage for cats every couple months because they get used to one flea killer (told to us by the vet) They are still going to scratch some because the flea has to bite them to actually die and so they will itch some and they will scratch like we do when we have an itch. If they lick it, it shouldn’t hurt them but I am told it tastes bad to them. Good Luck.
