Honestly, you should only buy your flea medications from a vet. Often the ones you buy over-the-counter or on-line are not the same formula (some are weaker or knock-offs and don't work and some are downright dangerous). If you buy from a vet he/she will know the correct dosage for your cat's weight/age and will have the legitimate product, AND, he/she will be able to answer your questions.
