The most effective cat flea treatments available contain
fipronil as the active ingredient, which was first used in Frontline
Spot On. Other cat flea treatments have been developed to work in the same
way, including Fiprospot and Effipro.
FRONTLINE and Fiprospot are available in packs of three or six doses, whereas
Effipro comes in packs of two or 24 doses and tends to be the most economical
product to use. Indorex is
our recommended household treatment.
