I did not notice any difference after putting this on my cats, they have had it on for a week now and I am still combing out fleas that do not appear to be slowing down. I was hopeful because the price is fair, however you only get 3 in the pack unlike the other top brands you get a 4 month supply.  see moreof tmitch22's review

    This product from Hartz works well, when applied the amount is very small which is great for cats! Its far superior than the other topical Hartz products on the market! However it is becoming harder to find, I am so pleased I can still order it from!  see moreof Nicmetro's review

      But this is alot cheaper. They both contain the same main ingredient fipronil that has proven itself effective in preventing fleas. I've been using this product for years, every month and my cats have been flea free. I have one indoor and one outdoor cat.  see moreof Jen's review

        Our dog (3 month old poodle) is not at all interested in these. She like almost everything else we have tried but I would recommend something else for people who are out shopping for something for their dog.   see moreof Rougeboy's review
