  • It works!
    I was very surprised when I tried Capstar. I didn't know what to expect and thought, here goes another thing that won't work..It worked! It's continued working since I started my Gigi on it. I couldn't be happier and neither can she. She was in agony scratching and was covered in fleas every time I bathed her. I'm so happy I've found a solution for her & our problem! Thank you, Capstar! by on 08/19/2020
  • Works Great!
    I have nine indoor only cats that got fleas?? Don't know how. I used Capstar flea killer and it works. I would crush up the pill and put it in their food. The pill is tiny so when you crush it, the cats don't see a thing. It only kills the adult fleas for 24 hours. You need to use something else to kill the babies. by on 01/27/2019

  • Capstar Fizzle
    We used this product a few months ago and it worked fine. Either this shipment was bad or the fleas gathered a very fast tolerance. The fleas were back within a week. by on 05/02/2016
