Hi there, Is it possible to give my cats Johnsons 4fleas tablets as well as frontline spot on? The spot on runs out anyway on Saturday but has proven inaffective to this bout of fleas so was wondering if it would be safe to give them a tablet now or wait?

If the active ingredient is Nitenpyram (I am having trouble finding this product online but I believe this is the ingredient) then it is fine to give along with Frontline. If you are having a problem with fleas in your cat you may need a prescription product that works long term from your vet such as Comfortis in addition to treating your home, all other pets, and your yard. You can read more about flea control at http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1575 Always be sure you are using a product labeled for cats, as some flea products for dogs are toxic to cats.
