the treatment you choose should depend on a few things, such as the climate (fleas just for summer or most of the year?) and the intensity of infestation, along with consideration of the cat's age/health/weight/indoor or outdoor/etc

i recommend those frontline// advantage // revolution style (do not buy the cheaper versions, they are utter rubbishy shit) treatments if you've experienced multiple flea episodes or if the infestation grows beyond just the cats getting bitten (which will happen easily if untreated, flea eggs do not stick to surfaces, rolling off into the carpet and furniture PLUS they have the ability to remain dormant for very very long periods of time if no food sources are detected)

another bonus of the application of the lethal hair coating (which should remain in effect ~1 month) is that the fleas will usually prefer the cat to the people, which pulls an auschwitz style roundup, removing the menace entirely as they are killed before being able to reproduce, sparing you from having to carpet bomb or call an exterminator

sorry for going all jeanette x yall if you cant tell i've had fleas
