unopened package. None of the little foils inside were open or separated. Got an applicator out of the foil and it’s FOR DOGS. 45--88 pound dogs. DOG FLEA STUFF KILLS CATS. The codes on both the cat packaging, and the actual product which is for dogs are on this site as proven counterfeit. 65331-4 and 65331-5.
