1. Activyl Cats
Activyl Spot-On Flea and Tick Control for Cats & Kittens
Activyl contains a lethal active ingredient, Indoxacarb, which works by using a method called bioactivation
in which Indoxacarb is activated using the flea’s own enzymes. When a flea attacks your pet, it absorbs
the active ingredient, which causes the enzymes within the flea’s gut to change. The flea becomes too
weak to feed due to paralyzing effect of Activyl and dies.
