  • Comfortis
    Seems to do the job. My dog hates the taste so I have to push it down her throat and give her a treat immediately after but that works. by on 02/21/2019
  • worng size tabet
    We ordered the pill indicated for the cats size. The pill that arrived is much larger than the ones we purchased from the vet. It is monthly torture to get her to take it. It did arrive fast. by on 01/30/2019
  • Works when nothing else will
    My poor cat has been through the ringer when it comes to fleas. He's allergic to flea bites, and we found he is allergic to most topical flea medications. We've tried everything from topicals, powders, flea collars, flea baths, and oral tablets. When we found Comfortis, it was a total lifesaver. We never find fleas on him anymore, and although he hates to take pills it is still effective when we crush it up and put it in his food so it's fairly easy to get him to take it. If you've tried everything and nothing will work, I suggest giving this a go! by on 12/04/2018
