Stronghold for cats a great product
Been using Frontline for years but cats became resistant. When I just started having fleas jump on me I tried this at a friends recommendation with great results by the 2nd dose. My cats do not go out except for an occasional escape which could bring in fleas since I live on 2 acres. I am happy with the results plus my girls dont seem as bothered by the application like they were with Frontline..
