One little flea can't possibly be a problem, can it?
It can. A single female flea can produce up to 50 eggs a day,1 turning ?one little flea? into a full-blown infestation before you even know it's there. Comfortis? (spinosad),now available for dogs and cats, starts killing fleas before they lay eggs and provides a full month of flea protection to help prevent future flea infestations."
And Comfortis is easy to administer! A flavored tablet is administered orally, so no residue, no worries about washing off after swimming, bathing, or grooming.
