Both
advantage and
advantix contain the ingredient imidacloprid to repel fleas, both are produced
by Bayer corpor- ation, both are applied topically, monthly and both are
water resistant. However, k9 advantix contains
an additional ingredient, permethrin, that advantage does not have. This additional ingredient
works in combination with the imidacloprid to control fleas, ticks
and mosquitoes,
something that advantage alone cannot do. Although advantage can be used on cats,
advantix is different, advantix is designed for dogs only and should
never be used on felines.
