I was asked by a vet who wished to remain anonymous to point out the warning label: "CAUTION: Federal (U.S.A.) law restricts Advantage Multi® for Cats (imidacloprid + moxidectin) to use by or on the order of a licensed veterinarian. WARNINGS: Do not use on sick or debilitated cats or ferrets. Do not use on underweight cats. (see ADVERSE REACTIONS). Do not use on cats less than 9 weeks of age or less than 2 lbs body weight. Do not use on ferrets less than 2 lbs body weight. PRECAUTIONS: Avoid oral ingestion. HUMAN WARNINGS: Children should not come in contact with the application site for 30 minutes after application." Sorry about being so quiet. After much up and down for a number of months Steve and I have had a bereavement in our human family, and we have two other senior relatives in delicate shape, so we have been living on a roller coaster for a while and will continue that way.
