Comfortis is the first once-a-month chewable flea preventative approved by the FDA. Starting to work within just 30 minutes, this tasty, beef-flavored tablet provides the same protection a topical treatment does, with all the ease of giving your pet a treat. While other flea treatments may simply kill fleas on contact, Comfortis actively repels fleas for a full 30 days. Since there is no mess on their fur, there is no time period where they need to be kept away from children or other pets either. Safe for use on cats and dogs 14 weeks and up, start making flea medication a pleasant experience today, with Comfortis chewable tablets.

When our dog had fleas and we couldn't get rid of them, our vet recommended Comfortis. It is expensive but it does the job well.

Using comfortis, completely takes care of any fleas any time of the year. Our dog is outside and inside. No itching,
doesn't make him sick. Other products we have used have almost paralyzed him and didn't get rid of the fleas.
Very happy with Comfortis , except for the price.

Rated 4 out of 5 by Sallie So Far this is the only Product that has worked
It has only been two weeks since the product was given to my two cats. I had one cat that continually had fleas. Frontline, Revolution and other topical products did not work. The pills were huge and I did not think I would be able to get my finicky cats to eat them but after breaking them up to small pieces they ate them down like snacks.
Still waiting to see if they continue to do the job but so far they seem to be working with no side effects noticed.

We have 3 dogs and though we never had anything like an infestation occasionally the dogs would get fleas.
We tried every spot on product out there but none seemed to work. Comfortis wiped them out in a day.
We live in the country where we sometimes have to "rescue" an abandoned dog.
There was one that was completely covered in fleas and 1 pill cleared them out in 1 day.

So much easier to give a pill and have it done. Can't use the stuff that goes on the skin because it makes them itch

Excellent Product, but I think I will switch to Trifectis next time.

Rated 5 out of 5 by Marge23 Saved me!
After the frontline stopped working we were infested. My sister told me about this product. As promised 10-20 minutes after ingestion, the fleas started to die.
After using for awhile, not sure it has to do with the product, my dog has been constantly scratching and digging at himself and his skin if scaley and flaky, but I'm not seeing any fleas.

I'd tried just about everything to fight back the flea infestation that was taking over my poor pooch's life. She could barely take a step before having to stop and scratch. Since giving her comfortis, she has been able to sleep soundly and get from point A to point B in record time. I highly recommend this for anyone finding the topical applications no longer effective.
