Review title: No longer works
Product review: Did you change the recipe Frontline? Is this a conspiracy on your front, or are the fleas conspiring against me? Anyway, my animals all continued to itch like crazy and I continued to find fleas on them after multiple applications (several months). So this is a product that doesn't do the one job it's sold to do.
