The three cats are indoor-only pets so I surmise the flea must have been picked up at an open window or at the back door, where they spend a lot of their time lazing during the Summer months. There are a lot of squirrels and other critters around all the time outside. Or could one of us have picked up the flea outside and brought it indoors on our clothing?
What should I do - are flea collars effective? Comments & tips would be appreciated. What a way to start my day off.
